“…Although the generation is expected to be maximal during peak summer months (May, June as per local meteorological conditions); however, the maximum generation about 7,197.53 kWh is recorded in the month of April. It has been observed that solar irradiance and local ambient temperature have a significant influence on energy generation; however, it also upsurges the PV module temperature . This leads to a reduction in the conversion efficiency of the modules and consequently, affects the generation.…”

Currently, India is espousing nonconventional energy sources at an express rate owing to concerns about climate change, emission of harmful greenhouse gases (GHG), and exhausting conventional energy sources. The solar photovoltaic (SPV) plants are, hence, expected to play a noteworthy role to meet energy security and sustainability goals. Contemporary studies reveal substantial ecological concerns associated with installing the ground mounted SPV plants in urban locations. Further observations depict that aforementioned plants need additional land, transmission, and distribution infrastructures. Consequently, rooftop SPV plants are the best solution to produce energy in urban locations, owing to the availability of a large number of empty rooftop spaces with least capacity expenditure. The present article discusses the techno-economic and ecological aspects of a 50 kWp rooftop SPV plant installed at ICFAI University, Jaipur. The plant has produced around 64.149 MWh in the year 2017. The technical assessment focuses on the effects of the meteorological parameters upon energy generation factors. The annual average final yield, reference yield, capacity utilization factor, and performance ratio found to be 106.9 kWh/kWp/month, 149.7 kWh/kWp/month, 14.64 and 70%, respectively. The economic parameters like net present value, internal rate of return, profitability index, and payback period are computed with 0-50% subsidy rates, which supports the financial viability of the plant. The plant contributed significantly to reducing GHG emissions by mitigating 102 t CO 2 , 128 kg SO 2 , 268 kg NO x , and 7,033 kg ash in the year 2017 as evident from the ecological investigation.Statement of industrial relevance: Manufacturing industries are extremely power intensive, as they utilize a substantial amount of energy during the production process. The utilization of sustainable energy sources can considerably curtail the major overhead cost, that is, power, and at the same time minimize pollution. Solar energy utilization is a viable option as large spaces are available not only on rooftops but also allied spaces like parking lots of the industries for installation of rooftop SPV plants.The industries by virtue of location receive extended periods of unimpeded sunlight, as these setups are positioned in separate industrial areas away from residential

Results obtained from monitoring an outdoor experimental 8 kW distribution gridtied solar photovoltaic (SPV) system installed at Energy Technology Station known as KwaZulu-Natal Industrial Energy Efficient Training and Resource Centre (IEETRC) of Durban University of Technology, South Africa is presented in this study. The study was carried out to investigate and compare the system performance with similar installations in a few selected countries. Data were collected between January 2018 and December 2018 and computational analysis was completed with the aid of Simulink and MS-Excel. The evaluated monthly average daily and annual performance parameters of the SPV systemarray yield, reference yield, final yield, system efficiency, inverter efficiency, capacity factor, and performance ratiowere discussed in term with the International Electrotechnical Commission (IEC) standard. A comparison of this study to other studies conducted in Dublin, Morocco, India, and Spain shows that this study final yield and performance ratio of 4.93 kWh/kWp/day and 87.1% is greater than what is reported in the extant literature.

A large number of grid-connected Photovoltaic parks of different scales have been operating worldwide for more than two decades. Systems’ performance varies with time, and an important factor that influences PV performance is dust and ambient aerosols. Dust accumulation has significant effects depending the region, and—on the other hand—understanding the role of absorption or scattering in particular wavelengths from aerosols is a challenging task. This paper focuses on performance analysis of a grid-connected PV system in Central Greece, aiming to study these effects. The methodology of analysis follows three directions, namely, PR computations, use of mathematical model’s prediction as reference value, and normalized efficiency calculation. These metrics are correlated with the levels of dust accumulation on PV panels’ surfaces and the ambient aerosol mass concentration. The results show that only heavily soiled surfaces have significant impact on PV performance and, particularly, a decrease of 5.6%. On the other hand, light or medium soiling have negligible impact on PV performance. On the other hand, the impact of ambient aerosol concentration levels on PV efficiency is more complex and requires further study. Aerosol scattering of different wavelengths can possibly affect PV efficiency, however, this fact may be related to the specific spectral response of PV cells.
