“…A dusty module heats up faster in comparison with a cleaner module, which in turn reduces the energy generation. The onset of rains in the month of July, therefore, leads to more energy generation in comparison with June, owing to lower ambient temperature and cleaner modules in spite of the increased humidity . High water vapor content in the air causes nonlinear deviation of irradiance occurs on account of nonuniform distribution of water vapor owing to humidity .…”

“…This acclaims that the minimal consideration of the life of the SPV plant as 30 years is acceptable for future techno‐economic investigation. Table illustrates a comparison of the performance factors of the plant with other plants installed in India. As per the observations, the functioning of the studied plant is quite satisfactory.…”

“…The GHG mitigation is the amount of GHG emission lessening by producing the energy from the SPV plant that would otherwise release by the thermal power plant. In Indian conditions, average CO 2 , SO 2 , NO x and ash mitigations per kWh can be taken as 1.58 kg, 0.0019 kg, 0.0041 kg, and 0.11 kg, respectively …”

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

“…Lower PR in summer months was caused by weather conditions as ambient temperature and horizontal global irradiation. In summer in Cairo temperature can achieve over 38 [24]. The lack can also be caused by the covering of PV modules by a layer of speck and dust.…”

Abstract. Photovoltaic installations are becoming an increasingly important player in the global renewable energy production market. The biggest disadvantage of photovoltaic installations is their high price, and relatively low efficiency. Photovoltaic cells achieve a theoretical efficiency of 30%, but in real conditions this efficiency is much lower at roughly 15%. Photovoltaic installations are particularly recommended in locations where the amount of solar radiation is high and where photovoltaic installations will be able to work at full capacity for most of the year. The paper presents an analysis of the work of a photovoltaic installation built for a roofed car park located in eastern Cairo, the capital of Egypt. The installation is built for a car park located at the Schlumberger company. The installation is built of 1344 Hanwha Q.Power L-G325 silicon polycrystalline cell modules, each module has a power of 325 Wp, and the total area of the installation is 2,611 m 2 . Effective irradiance on collectors is 1922 kWh/m 2 . The array's nominal produced energy was 840 MWh/year, the amount of electricity injected into the grid was 587 MWh/year, which means that the calculated performance ratio was 0.62.

This paper presents the assessment of solar resources, investigation of performance, and estimation of normalized performance indices of a 1 kWp Solar PV system in India's climatology of an isolated hilly area. The monthly and yearly mean normalized performance indices are estimated. The annual mean values of the daylight hours, cell temperature, and ambient temperature are 12.7 h/d, 10.89 C, and 1.25 C, respectively. The yearly mean values and corresponding ranges of monthly mean values of capacity factor, performance ratio, array yield, reference yield, final yield, array capture loss and system loss are obtained as 23.60%, 59.82%, 2.83 h/d, 4.63 h/d, 2.69 h/d, 1.8 h/d, 0.14 h/d and (17.56-29.07)%, (47.93-75.55)%, (2.24-3.42) h/d, (2.85-6.1) h/d, (2.13-3.25) h/d, (0.60-2.99) h/d and (0.11-0.17) h/d, respectively.The Levelized Cost of energy is reduced to 85% and 68.22% by using the proposed solar PV/ battery system compared to DG and DG/Battery systems. A saving of 14.8 kl of diesel and the corresponding reduction of emissions of carbon monoxide (244.22 kilograms), unburned hydrocarbons (10.66 kg), particulates (1.48 kg), and nitrogen Oxides (229.42 kg) have also been achieved per year. These findings effectively provide optimal power solution strategies for policymakers in the concerned area.
