A solar PV project equipped with single-axis tracking equipment can generate around 34% more revenue over 25 years compared to a conventional fixed-tilt solar PV project through increased power generation. Tracking equipment increases the plant load factor from an average of 19% for fixed-tilt projects to around 25% for tracking projects. This additional generation of around 22 million kWh over 25 years provides opportunities to earn additional revenue from power sales and renewable energy certificates. While tracking equipment represents only a 12% increase in capital costs, the increased revenue potential justifies the additional expenditure with payback periods of 2-4 years.

This document discusses using bifacial solar modules in east-west orientations to better match solar power generation to load profiles. Simulations show bifacial modules in east-west orientations can generate more total power over a day compared to south-facing monofacial modules due to light collection from both sides. However, shading losses increase at high density spacings. Using reflective material between modules can significantly increase power output by over 60% by reflecting more light to the rear side. Proper system design accounting for load profile, storage costs, reflectivity and other factors is needed to determine the most economical solar solution. Further measurements on real systems are still required to improve simulation accuracy for bifacial modules.

IRJET- Comparative Study of Maximum Power Point TechniquesIRJET Journal
This document compares different maximum power point tracking (MPPT) techniques used in photovoltaic (PV) systems. It evaluates the performance of incremental conductance (INC), perturb-and-observe (P&O), and fuzzy logic controller (FLC) MPPT techniques under changing weather conditions. The results show that INC performed the best in both dynamic response and steady-state operation, followed by P&O and FLC. It also discusses issues with conventional MPPT techniques like continuous oscillation around the maximum power point and loss of tracking direction during rapid irradiance increases. A modified P&O technique is proposed to address these issues simultaneously.
Energy Storage Technoecon Final Report_Revised March 2014Puneet Mannan
This document provides a techno-economic comparison of three energy storage technologies - sodium sulfur batteries, compressed air storage, and power to gas - operating with two wind power facilities in Alberta under different strategies. It models 16 scenarios using actual 2012 wind and electricity market data from two wind farms. The results show that co-locating an energy storage facility can increase total revenues for a wind operator by 28-50% compared to operating without energy storage. The increased revenues come from storing low-cost electricity and withdrawing it during higher price hours. Operating costs and losses from the storage technologies partially offset the higher selling prices.

It notes that O&M budgets are typically 1-5% of installation costs but can vary significantly based on plant characteristics, contractual agreements, and other factors. As installation costs decrease, O&M is becoming more important for project economics. The document outlines key factors that influence budgeting, such as maintenance strategies, contractual structures, and budget development terms. It also provides details on typical budget line items and ranges, labor requirements, and insurance considerations for PV O&M. Finally, it proposes ways to improve transparency and standardization around O&M budgeting processes.

IRJET- Modeling, Simulation and Control of a Photovoltaic Energy System w...IRJET Journal
The document presents a photovoltaic (PV) energy system with a fuel cell backup to ensure continuous operation of connected loads. The PV array normally powers the loads when solar irradiance is within its nominal range. When irradiance falls below a threshold, the fuel cell takes over to feed the loads. The proposed hybrid system is simulated in MATLAB/Simulink. Results show the system can efficiently address the intermittent nature of PV power by integrating a fuel cell backup.

Report on the IMPROVING THE EFFICIENCY OF SOLAR PHOTOVOLTAIC POWER GENERATION...Yuvraj Singh
The document is a seminar report on improving the efficiency of solar photovoltaic power generation. It discusses several ways to improve efficiency, including improving the conversion efficiency of solar panels, using automatic solar tracking systems, implementing maximum power point tracking technology, and exploring complex photosynthesis mechanisms. The report analyzes these methods and concludes that using these technologies can effectively improve the efficiency of solar power generation.
The document discusses a hybrid controller for renewable energy power plants in stand-alone sites. It describes a prototype hybrid solar PV-fuel cell-battery-diesel generator system of up to 5 kW that was developed. Experimental testing showed the controller effectively switches between the different power sources based on availability and load demand. A cost-benefit analysis found the hybrid system has a payback period of 5-10 years compared to a traditional diesel-battery system due to lower operating costs and carbon tax savings over the 30-year lifetime. The technology has commercial potential for powering telecom towers, hospitals and other remote facilities independently of the grid or continuous renewable energy availability.
This document outlines an energy monitoring and management program for an industrial plant. It includes:
1. Monitoring energy consumption from electricity and fuels across the plant to understand energy use.
2. Analyzing energy use of specific plant processes and equipment like DG sets, motors, compressors to identify inefficiencies and savings opportunities.
3. Providing reports on energy use metrics like power factor and consumption over time to track performance.
The goal is to understand energy use at the plant to identify areas for improvement and set targets to reduce energy costs through efficiency measures and demand management.
Drivers and Barriers in the current CSP marketLeonardo ENERGY

This project aimed to build a small-scale wind energy storage system using a lead-acid battery. An AC-DC rectifier circuit was used to simulate the output of a small wind turbine, charging a 12V lead-acid battery. A controller circuit regulated the charging to avoid overcharging the battery. When charged, the battery provided electricity to loads through a 150W inverter. Testing found the system could charge the battery in 6 hours and power loads for 57 minutes, with 89.3% efficiency. However, limitations included not using a real wind turbine and higher capacity components being too costly. Overall, the project demonstrated a basic wind-battery energy storage system as a model for further study.

How Changes to Time of Use (TOU) Rates are Impacting Commercial & Industrial ...Jim Dodenhoff
The significant penetration of solar energy in the electricity supply mix, especially in Western U.S. states, has resulted in profound changes to the shape of electricity system load curves. In the past, utility electricity suppliers with summer peak demand generally found their load peaking from mid-day to late afternoon. These same geographic areas have also been the most attractive candidates for solar implementation. The net effect has been a shifting of system net daily peak period to later in the day: spanning mid-late afternoon to early-late evening.
A guiding principle behind most ratemaking is to have electricity rates reflect real-time system costs. This provides higher pricing signals to the customer when the system has less available supply of electricity. Many utility tariffs are now either incorporating Time-of-Use (TOU) tariffs and/or moving their peak periods to later in the day to more accurately reflect net system peak and the impact of significant solar supply. These changes can have large cost impacts on Commercial & Industrial end users who have significant load in the evening hours.
This presentation will model these TOU tariff changes in California and other Western geographic areas. Energy management technologies such as energy storage and advanced controls will be analyzed as potential solutions to mitigate increased costs from TOU tariffs.
Finally, the carbon-intensity of unique utility electricity grids will be analyzed in the context of TOU peak periods. The author will present findings showing whether purchase of utility electricity during daily peak periods buys into a higher carbon emitting generation fleet, and to what degree.
IRJET- Various MPPT Techniques for Solar PV SystemIRJET Journal
This document discusses various maximum power point tracking (MPPT) techniques used in solar photovoltaic (PV) systems. It describes the need for MPPT controllers to extract maximum available power from PV arrays and compares different MPPT algorithms, including Perturb and Observe (P&O), Incremental Conductance (INC), Artificial Neural Network (ANN), and Fuzzy Logic Controller. For each technique, the document outlines the basic principles, methodology, advantages, and limitations. It concludes that MPPT is crucial for improving PV system efficiency and that the appropriate choice of MPPT method depends on the specific PV system application.
IRJET-Review on Solar Thermal and Photovoltaic Energy SystemIRJET Journal
This document summarizes and compares solar thermal and photovoltaic energy systems. Solar thermal systems indirectly generate electricity by using solar collectors to heat a liquid or gas, then converting the heat to electricity. Concentrated solar power is a type of solar thermal that uses tracking mechanisms to focus sunlight and achieve higher temperatures and efficiencies. Photovoltaic systems directly convert sunlight into electricity using solar panels without heat exchange. While photovoltaic systems have higher energy production, even at low light levels, their limitation is lack of cost-effective electricity storage. Solar thermal systems allow for thermal energy storage at low cost and therefore can provide dispatchable electricity production. Both systems show potential but differ in energy conversion methods and ability to store excess energy
