Introduction
I. INTRODUCTION
In today's world of technological developments, electricity plays a crucial role for a nation's development, for both developing and developed nations the challenge is being able to meet the growing demand for energy. According to a report from the Central Electricity Authority in 2018, it is observed that there is 8629 million units in energy supply but simultaneously 3314 megawatts in peak power demand. [1] To satisfy such demand, production needs to increase. Considering the limitations of conventional power sources, we go for alternative energy sources like solar and wind. This paper discusses on solar energy generation by designing a Grid Connected solar PV setup of 2.6 Kw power capacity in the location of Mangalpalli, Telangana. These systems are capable of feeding electricity directly into the connected grid, operating alongside conventional sources of energy. These produce clean electricity near where it's used, reducing losses and eliminating the need for batteries. [2] Their performance depends on local factors such as climate, PV Array orientation, and inverter efficiency.[3] Hence there is a need of a method to determine efficiency of such PV installations in a way where all technical, economic and annual performance aspects gets covered. For such designing and analyzing of PV systems, there are various tools available. These tools are implemented by engineers and scientists for optimization and analysis. Such tool is PV Syst, a PC software that was developed by the University of Geneva, it offers pre-feasibility analysis, simulation and forecasting for PV systems.[4] This research paper aims to design and simulate a 2.6 Kw solar PV system to implement 3-step method for efficiency evaluation in order to assess the energy production potential of this PV system.
II. METHODOLOGY
This paper proposes a 3-Step methodology where the complete evaluation of a PV system is divided into three important steps. They are-
A. Parameter Analysis
The Primary Block that extracts electricity out of solar irradiation is a solar cell. A solar cell produces output power according to its characteristics under different conditions. These characteristics examine Voltage, Current and Power parameters of solar cell under normal under constant and varying temperature. These characteristics help us in understanding the stability, compatibility with the power grid, efficiency and performance under different levels of irradiation. Overall, this analysis covers aspects related to solar cell and its efficiency in generating a stable efficient power.
B. Performance Analysis
Performance analysis is studying the performance of the PV system by considering power production, losses, efficiency, balance, irradiation in order to achieve valuable information about power production and estimate forecasting of aspects that enable us to gain understanding about the efficiency of the technical aspects of a PV system. All the technical aspects of this PV system like power production, performance, efficiency are covered under performance analysis.
C. Financial Analysis
Financial analysis is the study in which installation costs and operating costs of the PV setup are considered to gain calculated analysis on income variation, yearly net profit which are necessary for the planning and organizing of a solar PV system. This also gives a proper estimate on return on investment and cumulative cash flow to the user which aids in pre-feasibility of the system. Overall, this analysis covers all the monetary aspects behind establishing a solar PV system. Fig I illustrates proper understanding of this methodology below.
Hence, the above analysis clearly shows that we saved 64.238 tons of CO2 emissions this proves the feasibility of this system. So, we can say that this PV system improves air quality, supports bio diversity and ecosystem.[6]
From Financial Analysis, we can say that this system efficiently produces energy of 4121 kWh/year spent installation cost of 133,500/-INR and operating cost of 6,253.40 INR/year. Considering Project lifetime to be 20 years with start year to be 2020. According to the forecasting results of this analysis, payback period is to be 6.1 years with Return of investment rate of 569.6%. This shows that financial analysis was successful for this PV system.
Conclusion
In this paper, a 2.6 Kw Solar PV system integrated with Grid is designed and evaluated successfully using PV Syst software. It can be observed from all the analysis we have performed it proves this PV system to be stable, compatible with power grid, performs efficiently under different levels of irradiation and temperatures. Also, despite of minor losses the system is experiencing still persists to perform well and is potent in producing power for long term scale of time which makes this system financially secure and provides return on investment support and more profitability within 6.1 years of installation.
