چکیده انگلیسی

A study is conducted for solar PV energy generation from two grid-connected installations (mc-Si and a-Si power plants) located at the same place in Gujarat, Western India. Data-sets on electricity production were collected over entire year and compared under actual climatic conditions. The final yield of mc-Si power plant varied from a lower value of 2.79 h/d in the month of August to a maximum value of 5.14 h/d in the month of March. Final yield for amorphous silicon power plant varied from a lower value of 2.62 h/d in the month of August to a maximum value of 4.84 h/d in the month of March. The performance ratio (PR) of the mc-Si power plant ranges from 57.1 to 93.14 and for a-Si power plant, PR ranges from 53.72 to 87.64. The a-Si solar PV power plant found to have high capture losses as compared to the mc-Si solar PV power plant.

مقدمه انگلیسی

In the last decade solar energy has emerged as a promising resource of green energy alternative to non-renewable energy resources. Solar energy is probably the strongest-growing electricity generation technology, demonstrating recent annual growth rates of around 23% and worldwide production of 32.34 GW in 2012 consisting of both grid-connected and off-grid remote power supplies [1]. Besides playing the noteworthy role in the future energy blend, PV generation is significantly contributing to the environmental impact of electricity supply. PV technology is one of the best ways to harvest the solar energy since PV requires very little maintenance and is capable of giving output from microwatts to megawatts. Solar energy is effectively utilized in two ways, i.e., either by using it directly for heating or cooling of air and water without using an intermediate electric circuitry (i.e. solar thermal), or by converting it into electrical energy by using solar photovoltaic (PV) modules. Direct conversion of solar radiation into electrical energy is the most suitable way of utilizing solar energy. Among the various PV technologies, Si is one of the widely used semiconductors for the fabrication of solar cell. About 80–90% of PV cells manufactured worldwide are Si wafer based solar cells [2]. An elevated demand and exponential increase in the supply of components for PV systems have led to a very significant price drop per kW installed, and economic incentives have encouraged a large number of small investors to enter the emerging PV market. The world PV market is rapidly growing, attracting an enormous investment interest due to various lucrative schemes offered by different nations. The lucrative schemes guarantee a higher tariff as compared to the conventional sources of energy for 25 year period with a higher supplementary subsidy [3] and [4]. Recently, various studies related to performance enhancement, forecasting, maintenance, power conditioning and quality analysis of grid-connected photovoltaic power plant have received much attention [5], [6], [7], [8], [9], [10] and [11]. Due to ever increasing demand and supply of solar PV modules it becomes very important to compare the performance of available technologies in actual climatic conditions. In this article a comparative study on the performance of amorphous silicon (a-Si) solar PV power plant and multi-crystalline silicon (mc-Si) solar PV power plant (being a part of 1 MW power plant) under hot Indian climatic conditions is presented.

نتیجه گیری انگلیسی

A study is conducted for solar PV energy generation from two 500 kWP grid-connected installations (a-Si power plant and mc-Si power plant) located in same area, both of which experience the same fluctuation in temperature and radiation. This study shows that the final yield of mc-Si power plant varied from a lower value of 2.79 h/d in the month of August to a maximum value of 5.14 h/d in the month of March. Final yield for amorphous silicon power plant varied from a lower value of 2.62 h/d in the month of August to a maximum value of 4.84 h/d in the month of March. The performance ratio of the mc-Si power plant ranges from 57.1 to 93.14 and for a-Si power plant, PR ranges from 53.72 to 87.64. The a-Si solar PV power plant found to have high capture losses as compared to the mc-Si solar PV power plant.
