Abstract— Solar Energy is the prime important
source of energy, and it has continued to gain
popularity globally. As of 2018, about 486 GW of solar
PV was installed worldwide. One of the key
requirements for socio-economic improvement in any
nation of the world is the provision of dependable
electricity supply systems. Recently, there is a massive
growth in access to solar electricity in several Africa
countries, notably South Africa, Egypt, Morocco, and
Algeria. As a result, it decreases the global population
without access to electricity with an appreciable value.
This paper review the present state of solar energy
capacity in the world also identifies vital approaches of
improving their functionality, reliability, and
affordability as well as the essential method that
policymakers may implement in the future. The result
shows that there is a recurrent growth in solar energy
annually and as at the end of 2018 Asia with the largest
capacity of 56.58%, while Central America and the
Caribbean have the lowest installed capacity of 0.36%.
As the request for an uninterrupted supply increases in
different regions, progressive builders are embracing
solar photovoltaics (PV) renewable energy as an option
for their customers.
Prediction of the Power Output of Solar Cells Using Neural Networks: Solar Ce...CSCJournals
The prediction of the output power of solar cells in a given place has always been an important factor in planning the installation of solar cell panels, and guiding electrical companies to control, manage and distribute the energy into their electricity networks properly. The production of the electricity sector in Palestine using solar cells is a promising sector; this paper proposes a model which is used to predict future output power values of solar cells, which provides individuals and companies with future information, so they can organize their activities. We aim to create a model that able to connect time, place, and the relations between randomly distributed solar energy units. The system analyzes collected data from units through solar cells distributed in different places in Palestine. Multilayer Feed-Forward with Backpropagation Neural Networks (MFFNNBP) is used to predict the power output of the solar cells in different places in Palestine. The model depends on predicting the future produce of the power output of solar cell depending on the real power output of the previous values. The data used in this paper depends on data collection of one day, month, and year. Finally, this proposed model conduct a systematic process with the aim of determining the most suitable places for an installation solar cell panel in different places in Palestine.

Major depletion of fossil fuel and the increase of greenhouse gasses such as carbon dioxide, chloroflurocarbons (CFCs), hydroflurocarbon (HFCs), perflurocarbons (PFCs) and Sulphur hexafluoride (SF6) worldwide are the catalyst for the interest of many counties towards renewable energy. The rising cost of electricity due to higher demand and less resource also led to the renewable energy venture. One of the most famous renewable energy is solar energy. Unfortunately, renewable energies are dependent on environment conditions, too. One of the major problems that affect the output energy of the solar panel is the cloud shadowing problem. Photovoltaic solar and wind hybrid system is capable to reduce the effects of the cloud shadowing by harvesting two different energy resources. However, the availability of wind energy harvesting has shown its instability performance. In this work, the photovoltaic solar array of the laboratory-scale single axis solar tracking system to maximize the output energy of the solar panel is examined experimentally. The solar array is connected in series and parallel configurations, and is experimented under different partical-shadowed conditions. The experimentation is done to develop a solar array that has a minimum effect towards this type of occurances. Experimental results proved that the parallel configured solar panel has showed less influence by the cloud shadowing as compared to the single one.

This paper investigates the prospects and cost-effectiveness of implementation of standalone PV/wind system in sokoto state Nigeria. Daily electricity demand, yearly solar radiation and wind speed were applied to determine the optimum sizing of the renewable energy (RE) system. To design optimum RE with proper sizing of system components, meteorological data obtained from the National Aeronautics and Space Administration were applied as input for this study. In Nigeria, sokoto is a region with solar radiation of 6kWh/m 2 /day and wind speed of 5m/s at 10m above height. Using the Homer optimization software, the optimum integrated RE system is 35.21kW PV, 3 x 25kW wind turbines, 12 x 24V lead acid battery and 17.44kW converter. The system has a total capital cost of $249910.24, the replacement cost of $82914.85 and maintenance cost of $53802.80 for 25 years. Though the initial capital cost is high but the long term benefits are enormous, considering the high cost of implementing rural electrification scheme, coupled with ahike in electricity tariff. There is also a payback period of 5 years. The results imply a standalone PV/wind system is feasible in rural communities of sokoto with 100% pollution free energy system.
The utilization of conventional sources of energy releases harmful pollutants to the environment causing global warming and acid rain. For that reason, it becomes necessary to use a non-depletable, sustainable and eco-friendly renewable energy as a mean of producing electricity. Malaysia is tropical country rich in resources beneficial in electricity generation as it is in equatorial region therefore it has an abundance of solar irradiance of average annually. In addition, Malaysia’s demand in electricity is increasing to 124,677 GWh by 2020. Therefore, the electricity generation from renewable sources in Malaysia is anticipated to grow in the future alongside the government endorsement due to its clean, eco-friendly and free source of energy which can highly reduce the dependency on oil and gas that emits harmful pollutants to the environment. This paper gives a comprehensive review on the renewable projects and researches in Malaysia, challenges that affect popularity of renewable energy in Malaysia and available and successful renewable energy system in Malaysia.

Improving Efficiency of Power Systems by Demand Side Management Method Yayah Zakaria
In the smart grid infrastructure based power systems, it is necessary to consider the demand side management to enhance the energy reduction and system control. In many countries the resources are very less so the available
resources have to be used in an efficient manner without any loss. The total loss cannot be avoided but it can be reduced. In the proposed system, the Particle Swarm Optimization (PSO) technique is used to distribute the power in the smart grid. Here, the grids are arranged in such a way that the losses in it are reduced. The load connected to the grid is rearranged according to their use. It uses a new and stochastic scheduling technique to handle the uncertainties in the power system. Solar and wind power are taken in account for twenty four hours and the values are given to the PSO algorithm. The experiment was conducted by MATLAB and the results show that the efficiency level of wind and solar power systems was increased by an appreciable level. The proposed technique is compared with the normal system without using Demand Side Management (DSM) and it shows that the proposed system gives better results than the existing systems.

Sustainable energy in India: A Paradigm ShiftAdarsh Tripathi
This presentation briefly introduces with the current scenario of Sustainable & Renewable Energy in India. It also includes various government policies & various case studies from the very remote villages & locations of India.
The Renewable energy sources, especially wind turbine generators, are considered as
important generation alternatives in electric power systems due to their non-exhausted nature and
benign environmental effects [1]. The fact that wind power penetration continues to increase has
motivated a need to develop more widely applicable methodologies for evaluating the actual benefits
of adding wind turbines to conventional generating systems. In this paper reliability evaluation of
wind power generation system is carried. Reliability evaluation of generating systems with wind
energy sources is a complex process. It requires an accurate wind speed forecasting technique for the
wind farm site. The method requires historical wind speed data collected over many years for the
wind farm location to determine the necessary parameters of the wind speed models for the
particular site [3]. The evaluation process should also accurately model the intermittent nature of
power output from the wind farm. For the data analysis excel data analysis tool is used and
probability distribution of wind speeds are calculated [10]. This study shows the system availability
for the generation of power from wind turbine generators installed at the Hanamasagar, a village
near Gajendragada of Karnataka State.

Renewable energy plays a very important role in the improvement and promotion of environmental sustainability in agricultural-related activities. This paper evaluates the techno-economic and environmental benefits of deploying photovoltaic (PV)- battery systems in a livestock farmhouse. For the energy requirements of the farm to be determined, a walkthrough energy audit is conducted on the farmhouse. The farm selected for this study is located in southern Nigeria. The National Renewable Energy Laboratory’s Hybrid Optimization Modeling for Electric Renewable (HOMER) software was adapted for the purpose of the techno-economic analysis. It is found that a standalone PV/battery-powered system in farmhouse applications has higher economic viability when compared to its diesel-powered counterparts in terms of total net present cost (TNPC). A saving of 48% is achievable over the TNPC and Cost of Energy with zero emissions. The results obtained show the numerous benefits of replacing diesel generators with renewable energy sources such as PV-battery systems in farming applications.

Maximizing Output Power of a Solar Panel via Combination of Sun Tracking and ...ijtsrd
Energy is the basic needs for human comforts and day to day activities. Energy is the key factor for social and economic developments in today scenario. Now a day’s global warming is the main problem of developing counties, due to the nonstop combustion of fossil fuels all over the world, creating environmental hazards and reducing conventional energy sources. This scenario is contributing to the need to search for an new renewable source of energy, which is clean and available in excess. Due to the huge impetus in the government policies on the development of solar energy, it is acting as a main alternative renewable energy source. The solar energy is popular due to easy maintenance, cleanliness, sustainability, and zero noise characteristics. Therefore, Photo Voltaic module supplying loads with and without Maximum Power Point Technique MPPT is applied in the current studies to find the best results. Since the Photovoltaic array output is known to be affected by radiation of sun and temperature, which makes is compulsory to find out an effective method to draw out maximum power from Photo Voltaic cell modules. In my work, Perturb and Observe PandO algorithm is selected because of its easy implementation Solar energy is the clean and eternal source of energy till the end of the world. In this paper main focus is how to improve the efficiency of solar based power generation .Solar energy is variable depends upon the time and the atmospheric condition and hence output of the solar cell is directly proportional to the insulation level and inversely proportional to cell temperature and also the cell never operates at maximum power.

Modelling and analysis of a PV/wind/diesel hybrid standalone microgrid for ru...journalBEEI
The scarce electricity supply in Nigeria is a key factor to the low industrial development in a country well-known for having the least electrification in Africa per capita. Presently, Nigeria employs four different kinds of energy such as coal, natural gas, hydro, and oil. Three of the four resources mentioned above used for the production of energy in Nigeria is connected with increasing emissions of greenhouse gas: natural gas, oil, and coal, with coal releasing the worst. This paper presents a model and analysis of PV/Wind/Diesel hybrid system for rural electrification in Kaduna state, northern Nigeria. HOMER (Hybrid Optimization Model for Electric Renewable) software tool was used for optimization and modeling of this work. Simulation results show that the PV/Wind/Diesel system with Battery storage is the most cost-effective system since it recorded considerable cost of energy and reduces CO2 emissions significantly.
Solar technology offers great potential in terms of supplying the world’s energy needs. However, its current contribution to the world is still limited. The main factor is related to high initial cost of building the system. This paper will provide an up-to-date review of solar concentrators and their benefits to make solar technology affordable. It will also analyse on some of the existing solar concentrators used in the solar technology for the past four decades. The design and performance of each concentrator will be explained and compared.

The Internet has become one of the greatest inventions of mankind for learning and sharing of useful information through electronic means. For some years now, the developed nations have adopted the use of the e-learning system. Presently, the COVID-19 outbreak has given rise to the adoption of the e-learning system by many countries of the world being the most viable alternative for teaching and learning. This paper uses a pragmatic approach to evaluates the benefits and challenges associated with the e-learning system. A survey was conducted among students in a higher institution and a total of one hundred and twenty-five responses was gathered from the online questionnaire to know the likely challenges faced by students with the e-learning system and also at an online researchers’ forum. The result shows that 30.40% of students complained about weak internet connectivity from the questionnaire administered which is also the major problem in most developing nations, and for optimal performance of the e-learning system, there should be adequate provision for strong internet connectivity, standard IT infrastructure, and user-friendly e-learning platform.
Analysis of grid connected independent power plant capabilities on electricit...Najeem Olawale Adelakun
At the core of any meaningful economic activity is electric power. Absence or inadequacy of it in a nation
stalls development in that nation. In Nigeria, there is a wide gap between forecast power and actual
power generation needed for productive endeavours. For instance in July 2017, the generation peak load
forecast was 14190MW while the actual generation peak load was 4567MW. In July 2018 it was again
14190MW (forecast) but 5110MW (actual). This paper uses descriptive statistics to analyse Independent
Power Plant (IPP) capabilities spread across ten years (2009-2018). The results show that there is need
to encourage more private investors to build additional IPPs in order to increase adequate power
generation in Nigeria – especially in post-COVID-19 socio-economic crisis. Consequently, it is expected
that the wide gap between generation peak load peak load forecast and actual peak load would be
narrowed.
Wastage of water has been a
common phenomenon in several public locations
such as event centre, restaurants, malls, mosque,
churches, and also at home due to negligence of tap
user or due to sophisticated tap used that visitors
may not know how to operate, to curb wastage and
prevention of damage to the wash hand basin. A
solar-powered automatic wash hand basin system
was developed to cater for any challenges that may
arise. The solar-powered automatic wash hand
basin systemis a sensor-based system with constant
a supply of electricity that starts automatically
whenever anyone put his/her hand just below the
water tap outlet, which significantly reduces water
consumption to some extent and can as well
eliminate cross-contamination by keeping hands
and germs away from commonly-used surfaces
especially during this COVID-19 pandemic.This
system can help in automating the work of human
beings with great ease and without any difficulty
which will make the tap to last longer, reduce water
usage, and also guide against any form of germs or
diseases from cross-contamination.
The Relevance of Doubly – Fed Induction Generator (DFIG) in Modelling and Sim...Najeem Olawale Adelakun
The need for clean and stable electricity has given rise to renewable energy globally. Currently, Wind Energy generation is one the leading renewable energy sources and DFIG-based wind turbine are invariably the best approach to generate a multi-megawatts power at variable speed with less fluctuation in output power, ability to control its generated active and reactive power with minimal cost. This paper presents a model of a grid connected DFIG based Wind Turbine system for variable- speed where the speed range requirements are small, the overall system simulated using MATLAB/SIMULINK and the results shows the behaviour of DFIG with this type of control system and the numerous advantages in terms of cost reduction and the potential to build economically at multi-megawatt power system, as a result, DFIG grid connected wind turbine is essential.
The energy efficient load is considered as an important tool for efficient management of available
electrical energy in Nigeria because it allows electricity utility to meet the power demand of many consumers
with little or no increase in power supply generation. This paper discusses the technical and economic benefit of
using energy efficient load for electrical services design considering a four-bedroom apartment in Nigeria as a
case study. Load analysis and evaluation were carried out using both conventional load and energy efficient load
for electrical services. The technical benefits were determined by calculating the total energy demand, apparent
power and current drawn by the four-bedroom apartment. Apparent power and current are important tools to
determine Transformer capacity, Cable capacity and Generator capacity for the apartment. The economic
benefits were determined by calculating the daily energy consumption by the four-bedroom apartment and this
is a great tool in computing the daily cost of electricity by the apartment. The result shows that 41.26% of total
energy demand is saved and 32.96% of daily energy consumption is saved if the energy efficient loads were
used as an alternative to conventional load for that four-bedroom apartment.

Robots play important roles in day to day
activities of human endeavour and can perform
complex tasks speedily and accurately. Robots are
employed to imitate human behaviours and then
apply these behaviours to the skills that lead to
achieving a certain task in solving the challenges
faced by impaired people in society. This robotic arm
was achieved using light-weight steel iron for the
frames, a moderate torque MG995 Towerpro, and
servo motor. Two Atmega328 Arduino
microcontroller was employed to control the motors
through the use of pulse width modulation
technique. Mathematical models were developed for
the mechanism to represent the kinematics involved
at each joint with mathematical variables. Then, the
stability of the system was carried out using a step
input signal being a type zero system.
Outage analysis and system disturbances on 330k v and 132kv transmission syst...Najeem Olawale Adelakun
The Persistent power outage in the country due to
faults has become alarming to the government and the body
responsible for electricity generation in the country. It also
creates a major problem for electricity consumers in Nigeria,
there must be an improvement in the reliability of the
transmission system in Nigeria. This research work is
predominantly concerned with the analysis of outages on
330kV and 132kV transmission system, and system
disturbances on generation and transmission system for five (5)
years. The result shows that the forced outages are the most
occurred outages on the 330 kV line, while on 132 kV line,
emergency outages have the highest number of outages in 2014
but decreases rapidly over the years, similarly, twenty-seven
(27) major system disturbances occurred in 2016 with 31%
against ten (10) with 11% disturbances in 2015, while 2014 and
2018 with the same number of system disturbances of thirteen
(13) with 15%, it is apparent that more disturbances occur on
the transmission system, and there should be a proper
protection scheme to maintain stable grid network.
Consequently, Mini-grid and off-grid solutions will
prominently address the issue of power supply shortage and
instability in Nigeria.
Presently, there is rapid growth in Technology advancement. Developed countries are searching for new alternative energy sources to minimize the pressure on natural sources like gas, uranium, oil, coal, etc. However, natural sources of energy are inadequate and expensive, which also contributed heavily to greenhouse gas emissions. Developing countries like Nigeria are also trying to exploit different renewable energy sources like solar energy, hydropower, wind energy, bioenergy, etc. to accomplish their increasing demand and also to eradicate the energy crisis Nigeria has been experiencing due to insufficient electricity generation. This paper analyses the importance of renewable sources, the challenges and the benefits. This paper also analyses how renewable energy can be accepted as a perfect solution for economic development.
ABSTRACT
Electricity exists in a form that is useful to exploit, however, it will also be important to install electricity as
efficiently as possible, and design of the power distribution system should be convenient so as to minimize
power losses. This paper analyses the electrical service design of a Storey building using the lumen method for
the lighting calculations. The purpose of this work is to present a suitable approach to electrical services design
based on the provision of the Institution of Electrical Engineers (lEE) Regulations, which includes lighting,
power, distribution boards schematics. The results of the whole analysis and design was illustrated with
AutoCAD application. This work gives a direct approach from design of the electrical services to the installation
stage. The results of the calculations in the design helps the designer to make vital decisions such as types of
luminaries, sizes of cables and nominal ratings of protective devices required by each circuit and by the entire
installation in line with appropriate standards and regulations.
A STUDY AND ANALYSIS OF ENERGY GENERATION AND CONSUMPTION IN DANGOTE CEMENT ...Najeem Olawale Adelakun
ABSTRACT
Energy supply for economic activities has been a major problem in Nigeria such that it does appear that solution
to stable, reliable power supply is not yet in sight. Consequently, consumers (industrial, residential and
commercial) have all resorted to self-generation to complement whatever supply (if any) that comes from the very
unreliable national grid. For instance, the available power supply to the entire nation fluctuates between 3000MW
and 3500MW. A study of monthly energy generation in Dangote Cement Plant for a typical year was carried out.
This was compared with the equivalent monthly generation from the entire Nigeria’s grid system. The results
show that in 2013, at the early stage of commencement of production of operation in the plant), the total energy
generated by the Dangote Power Plant was 406762.33 MWH while the total energy consumed by the company
was 401903.72 MWh. Dangote’s total energy generation in 2013 represents 1.4% of Nigeria’s total generation
from grid in the same year. The total distribution loss was 4858.61 MWH (which is 1.2% of the total energy
generated by the company).Comparatively, the total generation from national grid in 2013 was 29628699. This
study further shows that Dangote Cement, Ibese produces enough energy for its use and could even sell any excess
if encouraged.
RETOOLING NIGERIAS ELECTRICITY GENERATION SUB – SYSTEM FOR SUSTAINABLE GRID O...Najeem Olawale Adelakun
ABSTRACT
Experts are varied in estimating the amount of power needed for national development. One expert
estimated 297,900 MW by the year 2030 using a 13 percent Gross Domestic Product (GDP). The Power
Sector Road Map’s aspiration is 40,000 MW by the year 2020 while the preferred Vision 20:2020 target is
40GW (40,000 MW) available capacity. Vision 20:2020 further proposed that hydro sources contribute 10%
of this value; thermal, 80%; coal, 6% and renewables, 4%. However, as at December 2017, Nigeria’s total
installed generating capacity was 12,324.40 MW. In order to assess the fundamentals and proffer solutions
for the improvement of power generation to meet popular expectations, this work analyses the installed
capacities of the nation from 1986 – 1995, on the one hand and from 2007 – 2016, on the other hand using
graphical illustrations and tables. The gap between the two time phases was deliberate to create some effect.
The results show that over the years, there has been an apparent, non – challance towards systematic
development of Nigeria’s power sector. To put a check to this deteriorating condition / trend, useful
suggestions have been made
Design and Evaluation of Electrical Services for an Energy Efficient HomeNajeem Olawale Adelakun
Abstract- Nigeria is facing an acute shortage of
electric power that drives economic activities.
Consequently, all sectors of the economy are facing
a retrogression in productivity. Besides, even much
of the power made available either from the grid or
self-generation is wasted due to poor installation
design and use of inefficient devices and equipment
such as filament bulbs, and fluorescent lamps
(among others). This work examines the present
common practice of electrical services that wastes
energy with the viewing to advancing the best
practice that minimises overall energy / power loss. A
three-bedroom flat and an eatery in Nigeria were
used as a case study. Load audit, analysis and
calculations were made to assist in making vital
decisions as to the types and sizes of luminaires,
cables and protective devices (among others) to be
used in accordance with known standards and
regulations. The results show that 71.8% and 69.1%
respectively of energy is saved for lighting in three-
bedroom flat and eatery; 37.4% and 30.8% in other
loads used in three bedroom and eatery respectively.
All this is as a result of use of frugal design and
energy saving – saving devices. This further implies
a saving in absolute cost of energy consumed in a
particular situation.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Abstract— Solar Energy is the prime important
source of energy, and it has continued to gain
popularity globally. As of 2018, about 486 GW of solar
PV was installed worldwide. One of the key
requirements for socio-economic improvement in any
nation of the world is the provision of dependable
electricity supply systems. Recently, there is a massive
growth in access to solar electricity in several Africa
countries, notably South Africa, Egypt, Morocco, and
Algeria. As a result, it decreases the global population
without access to electricity with an appreciable value.
This paper review the present state of solar energy
capacity in the world also identifies vital approaches of
improving their functionality, reliability, and
affordability as well as the essential method that
policymakers may implement in the future. The result
shows that there is a recurrent growth in solar energy
annually and as at the end of 2018 Asia with the largest
capacity of 56.58%, while Central America and the
Caribbean have the lowest installed capacity of 0.36%.
As the request for an uninterrupted supply increases in
different regions, progressive builders are embracing
solar photovoltaics (PV) renewable energy as an option
for their customers.

I. INTRODUCTION
Recently, the need for a clean and environmentally
friendly energy source has given Solar energy a
massive growth due to both technological
improvements resulting in cost reductions and
government policies supportive of renewable energy
development and utilization.
The solar energy system is the transition of sunlight
into electricity, it can be achieved directly using
photovoltaic (PV) panels or indirectly with the aid of
concentrated solar power (CSP). Concentrated solar
power systems with a total of 5,469 MW installed
capacity worldwide which amour to 1.13% of the total
solar energy installed globally. Solar Energy has an
estimated world-wide average power potential of
24W/m2
of the earth's surface [2]. As at the end of
2018 the solar power was about 486 GW globally.
According to the International Renewable Energy
Agency (IRENA) report, (2019) Nigeria with 19MW,
South Africa 2959MW, Egypt 770MW, Morocco 735
MW, Algeria 435MW out of 6093 MW Solar Energy
Installed Capacity in Africa 2018.
II. MATERIALS AND METHOD
The Photovoltaic system can be classified into two
parts which are the PV array (this includes the PV
panels and support structures) and the balance-of-
system (BOS) components (which includes storage
batteries, Charge controllers, inverters and wirings).
A. Basic Components of Solar Power
There are four basic components of a solar power
system: Solar Panels, Charge Controller, Batteries,
Power Inverter.
a) Solar panels: are composed of individual solar
cells that are connected to form a solar module and
multiple solar modules are connected to form a solar
array, it can be connected in series, parallel or series-
parallel combination for maximum power output.
b) Charge Controllers: Charge Controllers are used
to preventing overcharge of the battery by preventing
high voltage that damages the batteries. The minimum
charge controller for home uses a technology called
Pulse Width Modulation (PWM), but the best charge
controllers use Maximum Power Point Tracking
(MPPT) technology.
c) Batteries: Deep Cycle Batteries are needed for
the storage of electricity, but more specialized
batteries such as Tubular batteries are also gaining
popularity for larger applications like powering your
home.
d) Power Inverters: The electricity produced by the
PV panel is Direct Current (usually 12V, 24V, or 48V,
etc.), which is then converted to Alternating Current
(AC).
However, Fig. 1.0 shows that DC load can be
connected to the charge controller and battery storage
system respectively, it is essential to incorporate a
circuit breaker in between the charge controller and
the battery storage system to prevent excess current
to flow to the battery in case of short circuit. Which can
be replicated at all the necessary points.

There is a recurrent growth in solar power capacities
yearly as shown in Fig. 2, China tops the world with
the most capacity. Besides, Fig. 4, shows the
percentage of solar power capacity by regions in the
world, from the pie chart, Asia has the largest
percentage with 56.58%, the difference is not far-
fetched but since three countries from Asia is among
the top five countries with much capacity of Solar
energy in the world and Central America and the
Caribbean with the lowest percentage of 0.36%
respectively.
Fig. 5, implies that Solar Photovoltaic is the most
common with 98.87% installed capacity and only
1.13% from the Concentrated Solar power system,
and table 4, also depict that some regions of the world
have not explored the CSP approach at all, but some
with minimum installed capacity.

should be embraced owing to the benefits associated
with it, from the total solar energy installed worldwide
Asia has the largest installed capacity of 56.58%,
while Central America and the Caribbean has the
lowest installed capacity of 0.36%. As the request for
an uninterrupted supply increases in different regions,
progressive builders are embracing solar
photovoltaics (PV) renewable energy as an option for
their customers, moreover, if all the suggestions and
recommendations stated in the paper is implemented,
solar energy will be more functional, reliable and
affordable which will also help the deployment on a
large scale.
RECOMMENDATIONS
The following are suggested for improvement of Solar
energy power technology:
a) Renewable energy power station such as
solar (PV) should be actively encouraged.
b) There should be massive increase in
manufacturing capacity and more effort has to
be put into improving efficiencies while
reducing the manufacturing costs.
c) Installation of LEDs bulb instead of
incandescent or high power consume bulb.
d) Turn off all standby mode for used equipment.
e) Embraced the culture of energy efficient
home.
f) High consumption devices should be run
during the day when there is sun.
