By this time, solar technology is convenient, proven and well accepted in Bangladesh. It is
environment friendly and price of solar panel is decreasing day by day. Energy generation is one of the key
factors in driving the socio-economic growth of any country. In Bangladesh, increasing demands for energy has
already exceeded the capacity from existing power plants by conventional sources of energy. Rarikandi is a place
of cultivation, for this reason population is also higher in this region. Rarikandi has no direct connection with the
town because it is surrounded by a river. But Solar energy can bring a new era for the villagers. Energy status
will be discussed in this paper with more explanation and with present and future demand. The performance of
solar system in bangladesh has also been good, as the average irradiance remains 4.99 KWh/m2/day throughout
the year and the seasonal variation of insulation is small. Chattagram is the nearest place in RETScreen software
from where climate data is taken.
Standalone Solar Power Systems are completely independent from any electric utility grid. They are
most often used in remote areas where electricity is not available or where the connection fees of the grid are
higher than the cost of an alternative energy system. Standalone solar systems (also known as autonomous, or off
grid systems) are used to collect and store solar energy to be used by household appliances. The project at last is
only accepted if the cost of overall project is suitable for financing. In this paper the cost was estimated by using
Net Present Value (NPV) method. The aim of this paper is to investigate the possibility of supplying electric
energy from solar power to the village Rarikandi, Chandpur

Scenario of Rural Electrification in India- Challenges and ImpactIJERA Editor
In this paper, the present scenario of rural electrification in India is taken into account. Basically, the electrification in this country is facing a lot of problem and is a growing matter of concern for all. The development in production is not reaching the one who need them. Also taking into picture the present sources of energy it is difficult to make the electricity available to the people belonging to rural areas who don’t have much source of income. To overcome this drawback we can utilise renewable sources of energy which is easily available and accessible. Also harvesting this will not cost much except the initial cost of setting up the device to utilise this type of energy. Many projects have been initiated by the government of India to provide subsidy and equipments like solar lantern and solar cooker etc. to the rural population but this didn’t turn out to be effective as the follow could not be done by the people to maintain the devices. This can be overcome by implementing off-grid projects which can be initiated at small levels so that people don’t have burden to maintain them and it even don’t have any adverse effect to environment or society.
The development of a country is dependent on the per person energy consumption rate, which is very low
in Bangladesh. Bangladesh installed a capacity of 10416 MW electricity on June 2014 and three fourth of
which is considered to be accessible. Near about 45% people has no access to electricity. Therefore,
electricity shortage is an acute crisis in Bangladesh. As Saint Martin Island is far away from the main
land, it is almost impossible and cost ineffective to supply electricity from the national grid. For
connection of nearly 6000 peoples of Saint Martin to the main stream of development and to make this
island more attractive to the tourists, it is very essential to provide electricity for them. Power generation
by combining solar, wind and diesel, known as hybrid system can be the most efficient technique for the
electrification of these types of Island. Based on this principle, in this paper a hybrid system is designed
for electrification of Saint Martin’s Island. In the analysis, realistic data is used for load calculation and
optimization analysis for most effective solution. Hybrid Optimization Model for Electric Renewable
(HOMER) software is used to find out the final optimization and sensitive analysis of hybrid system. This
system satisfies the load demand and reduces carbon emission which will help to generate green energy.
Economic and Optimization Study of an Hybrid Solar-Diesel System for A Coaste...paperpublications3
Abstract: Photovoltaic power system has become most acceptable renewable energy system for rural areas that do not have access to grid system. This system was designed to supply electricity to Akodo which does not have access to the national grid network of power supply in Nigeria. Akodo, a community in Ibeju Lekki Local Government Area of Lagos State, which is made up of about 150 houses and requires about 89KW load which can be supply conveniently by the solar diesel system, is found to be more appropriate in this research work. The initial cost seemed to be on the high side, but on the long run the maintenance of the system which was very minute accorded the system significant advantage. It is now economical to embark on this research work which would be found to be highly beneficial.
Optimization towards cost effective solar mini grids in bangladeshDipta Majumder
People living in remote rural areas e.g. islands of Bangladesh don’t have access to electricity due to financial and technical challenges. Solar Photovoltaic (PV)-Diesel based hybrid mini grids can be a way to electrify remote rural areas of Bangladesh. However, solar energy is costly compared to conventional energy sources. Hence, optimization is essential to ensure success of solar mini grids in remote rural areas. Optimization of mini grid plant capacity based on demand is discussed. Diesel consumption and excess electricity from plant are the key optimization parameters. A case at Paratoli, Narsingdi, Bangladesh is taken into consideration to validate the optimization. Data is further analyzed to find out the future requirements and effects after optimization.

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.

Energy demand forecasting of remote areas using linear regression and inverse...IJECEIAES
Efficient energy demand forecasting is pivotal for addressing energy challenges in remote areas of Bangladesh, where reliable access to energy resources remains a concern. This study proposes an innovative approach that combines linear regression analysis (LRA) and inverse matrix calculation (IMC) to forecast energy demand accurately in these underserved regions. By leveraging historical energy consumption data and pertinent predictors, such as meteorological conditions, population dynamics, economic indicators, and seasonal patterns, the model provides reliable forecasts. The application of the proposed methodology is demonstrated through a case study focused on remote regions of Bangladesh. The results showcase the approach's effectiveness in capturing the intricate dynamics of energy demand and its potential to inform sustainable energy management strategies in these remote areas. This research contributes to the advancement of energy planning and resource allocation in regions facing energy scarcity, fostering a path towards improved energy efficiency and development. These techniques can be applied to estimate short-term electricity demand for any rural or isolated region worldwide.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract: By this time, solar technology is convenient, proven and well accepted in Bangladesh. It is
environment friendly and price of solar panel is decreasing day by day. Energy generation is one of the key
factors in driving the socio-economic growth of any country. In Bangladesh, increasing demands for energy has
already exceeded the capacity from existing power plants by conventional sources of energy. Rarikandi is a place
of cultivation, for this reason population is also higher in this region. Rarikandi has no direct connection with the
town because it is surrounded by a river. But Solar energy can bring a new era for the villagers. Energy status
will be discussed in this paper with more explanation and with present and future demand. The performance of
solar system in bangladesh has also been good, as the average irradiance remains 4.99 KWh/m2/day throughout
the year and the seasonal variation of insulation is small. Chattagram is the nearest place in RETScreen software
from where climate data is taken.
Standalone Solar Power Systems are completely independent from any electric utility grid. They are
most often used in remote areas where electricity is not available or where the connection fees of the grid are
higher than the cost of an alternative energy system. Standalone solar systems (also known as autonomous, or off
grid systems) are used to collect and store solar energy to be used by household appliances. The project at last is
only accepted if the cost of overall project is suitable for financing. In this paper the cost was estimated by using
Net Present Value (NPV) method. The aim of this paper is to investigate the possibility of supplying electric
energy from solar power to the village Rarikandi, Chandpur.
Keywords: Energy demand, solar potential, Load profile, system design, Cost estimation
I. Introduction
Less than half of Bangladesh’s population of 150.6 million has access to grid electricity; in rural areas,
where most people live, the percentage is even lower. Even those with access to grid electricity suffer
interruptions in supply because of serious power shortages. Today stands at around 40% of the total population
and has a large unsatisfied demand for energy, which is growing by 10% annually. Around 76% of the population
lives in the rural area have lower coverage of electricity. [1] Solar home systems are bringing the benefits of
electrical power to millions in rural Bangladesh, as a testament to the numerous and varied benefits access to
cheap, clean and renewable distributed solar PV can have in developing countries. Microfinance provider
Grameen Shakti’s efforts to market and sell solar home systems (SHS) in rural areas across the country that lack
grid access have proved extremely successful. [2] The main idea of this project is to make an independent solar
system which can able to provide sufficient amount of electricity in Rarikandi, Chandpur.
Energy generation is one of the key factors in driving the socio-economic growth of any country. In
Bangladesh, increasing demands for energy has already exceeded the capacity from existing plants from
conventional sources of energy. Thus access to electricity is very limited where Per capita energy consumption is
about 237 KOE [3]. In Bangladesh solar photovoltaic (PV) systems are being widely deployed in rural areas and
large scale coverage in rural areas with renewable energy sources is being actively considered with mini-grid
structure. ]. There are still lots of area where there is no supply of electricity [4].
Rarikandi village is located (23°23'37.5"N 90°40'18.3"E/23.393744, 90.67175) in matlab uttar upojila of
chandpur thana of chittagang(23.3°N91.8E) district.[5] Rarikandi is a place of cultivation, for this reason
population is also higher in this region. Rarikandi has no direct connection with the town because it is surrounding
by a river.
People of this village are mostly farmer and they need electricity only for irrigation purpose and for
normal living. So, for better life they need electricity. Figure 1.3 Illustrate the process how PV solar panel
batteries and inverter can be connected and supply electricity for daily purposes. Amount of cost estimation also
done for overviewing the system expenditure which is very helpful for Investigation.
II. Energy Status
In 2012, Bangladesh’s primary energy consumption was an estimated 56% natural gas, 24% traditional
biomass and waste, 16% oil, 3% coal, and 1% hydropower and solar. So far, in Bangladesh, up to 29 April 2012;
Infrastructure Development Company Limited (IDCOL) has installed 1,429,440 Solar Home Systems (SHS)

throughout the country [11] which clearly has been proved to be a very successful program in Bangladesh to
address the lighting demands. Solar photovoltaic (PV) systems are in use throughout the country with over 2.9
million household-level installations having a capacity of 122.2 MW (April 2014). [12]
Population Growth Rate:
The increment of population can be calculated using exponential population growth formula as:
= ∗ (1)
Where, P: Population after t years (in this case we choose 20 years’ time)
Po: current population (currently village has 700 populations) r: rate of increment (we assume 0.26%)
t: time period in years (we assume 10 years)
Rarikandi is a small area (8km2). In 1991 the total population in matlab uttar (Chengar Char)was
262,504 and in 2001 the population was 299,935 and in 2011 the total population was 292,057. The density is
1,122inh./Km2 and the population change rate 0.26%.[13] So in the year of 2022 the total population would be
300,713. But considering only the village rarikandi, every year new people are coming and started living In 2012
the total population was around 600 In 2025 the total population of in rarikandi would be around 10000. And their
demand will also increase and the amount of cultivated land will decrease.

Most of the part of Asia including Bangladesh also lies on subtropical region. Figure 3 and 4 show global
horizontal irradiance (GHI) for most of the Asian country which is provided by NREL (National Renewable
Energy Laboratory).

Average temperature data for chandpur from 1900 to 2009 are taken just for observing the lowest
temperature and highest temperature of the area.[14] From figure 3.4 it can be shown that minimum temperature
can be found in the month of January.

Figure 5 shows the temperature and rainfall history from 1990 to 2009. Minimum temperature can be
found in January February and December. So care should be taken for considering the worst condition for
designing the system.
Figure 6 represent the daily solar radiation data from RETScreen software and Daily Solar Radiation is
the amount of energy emitted by the sun, provides the range of daily radiation throughout the year for chattagram.
Optimum Angles for Solar PV Array Adjust by month [15] so, from the table tilt angle can be adjusted
through the year to get the maximum power from solar array. But for fixed tilted system, 67 degree with vertical
axis and 23 degree with horizontal axis. For setting up/construct the solar array with a fixed tilt angle is easier
than to make the array angle through-out the year. Adjusting of the tilt angle can be achieved by tracking system
or by manually-with the help of gear arrangement.
IV. Load Profile
Currrent load profile for the village rarikandi shows in table below. But every year new people are
coming and those people who are already living, they also increase their family. Considering the condition it can
be seen that the load demand is now around 200Kw and it will be increased day by day.In Load profile calculation
different time was taken for power supply For example each house will get 6 hours power supply and school will
get 8 hours.

V. System Design
Standalone Solar Power Systems are completely independent from any electric utility grid. They are
most often used in remote areas where electricity is not available or where the connection fees of the grid are
higher than the cost of an alternative energy system. Standalone solar systems (also known as autonomous, or off
grid systems) are used to collect and store solar energy to be used by household appliances. These systems
typically generate from 100 Watts (very small systems) to 5 kilowatts (larger systems, multi family homes).
During the day, the electricity generated is used to power the home and charge the batteries. At night, and during
rainy days, all necessary power is provided by the batteries.

DOI: 10.9790/1676-1061127135 www.iosrjournals.org 132 | Page
If the off grid home has no other power source, both the PV array and the battery bank have to be
significantly oversized by design to account for possibly 4-5 days of inclement weather.
Currently, PV is most competitive in isolated sites, away from the electric grid and requiring relatively
small amounts of power. In these off-grid applications, PV is frequently used in the charging of batteries, thus
storing the electrical energy produced by the modules and providing the user with electrical energy on
demand.[17]
Fig.7: Off-grid System line diagram
The DC electricity produced by the solar panel or module (s) is used to charge batteries via a Solar
charge controller. AC appliances are powered via an inverter connected directly to the batteries. Most standalone
solar system need to be managed properly. Users need to know the limitations of a system and tailor energy
consumption according to how sunny it is and the state of charge (SOC) of the battery. The solar panel need to be
configured to match the system DC voltage, Which determined by the battery. The operating voltage of a solar
panel in a off grid system must be higher enough to charge the batteries. A charge controller is design to control
and to protect the battery so long wording life time should be ensured without impairing the system efficiency.
Main purpose of the controller is to protect the battery from over-charging by limiting the charging voltage and
prevent the current flowing back (reverse current) into the solar panel during night. The charge controller passes
the generated electricity on to the batteries. The battery or stand-alone power inverter is the heart of the AC
coupled system. It ensures that generated and load power are balanced at all times. If too much energy is
generated, the inverter stores this surplus energy in the batteries. If energy demand exceeds supply, the inverter
discharges energy from the batteries. The battery storage system is generally configured to run at 24 or 48 volts. It
is contained in a separate room or enclose, if in the same room as the inverter and other componentry. A
management system that includes battery, generator, and load management is absolutely essential for the optimum
operation of a off grid power supply system. Cables need to be UV resistant and suitable for outdoor applications.
It is very important to keep power losses and voltage drop in the cable to a minimum. It is recommended that this
be less than 3% between the array and the batteries and less than 5% between the battery and DC loads.

VI. Cost Estimation
He project at last is only accepted if the cost of overall project is suitable for financing. In this scientific
project the cost was estimated by using Net Present Value (NPV) method which is discussed in this sub chapter.
The formula for NPV calculation is given in equation 3 as:
= − + Σ( − )/( )i
= ……. (3)
Where, Ao = initial investment, Ai = Annual investment, Zi = Annual payback, n = number of years, and q=1+p,
p = interest rate in %
At NPV = 0, 0 = -Ao + (Zi. /a), (we can write this from equation 3, where a=q−1/1−q−n )
From NPV method we can find the following three cases related to project financing:
1) If NPV = 0 ,Investment will be paid back with p interest rate within n years
2) If NPV > 0 ,Investment paid + profit from project
3) If NPV <.0 , Loss from project
For estimating the cost recent market price has been taken and using Net Present Value (NPV) method
NPV is chosen as zero. Cable cost and other costs like labor and maintenance cost are included for total project
cost estimation. But if government will provide some financial support then lower tariff can be obtained. So in
this case NPV is taken as zero.
Table below mentioned all the price list and total price for battery, inverter, and controller and PV
module are calculated and total project cost was estimated. NPV was taken as zero for calculating fid in tariff.
Table 9 : Price list for all products
PV module 0.473€/Wp
Inverter 1394€/piece
Controller 441.8€/piece
Battery 200€/piece

Total Controller cost 42,413€
Total Battery cost 2,83,200€
Extra (Labor, maintenance, 150,000€
others)
Total project cost 7,04,036€
On the basis of rough design, an initial estimate of system costs can also take place. The costs in the
calculation shown here include power inverter, PV module storage battery, installation cost and other cost.

VII. Conclusion
The major benefits would be a large amount of people can able to use electricity which can help them
to develop themselves and they can able to know what’s happening daily. This project is an example for Proper
utilization of solar energy and also a population free process.
Initial Cost is high for the owner of the station but government can also provide some financial help
which can be profitable but processing takes long time. Design must be perfect. Lack of knowledge about
proper maintenance of solar technologies can be an issue. Major limitation would be happened when rainy
season comes and solar panels are not able to provide enough electricity. In this circumstances power supply
may be cut off.
