The influence of solar power and solar flux on the efficiency of polycrystalline photovoltaics installed close to a river

Abstract

There is an increasing focus on utilizing the renewable energy resources, especially solar energy as the fossils are expected to deplete in near future. Solar Photovoltaics have remained of particular interest because of their relative lower overall efficiencies. Most researchers are trying to enhance the overall performance of Solar Photovoltaic and trying to study factor that may possible lead to an increase in the overall performance of a Solar Photovoltaic Panels. A thorough investigation was carried out to study the influence of solar power and solar flux on the performance parameters of Photovoltaic (Polycrystalline). The data used in the research was obtained by in-situ measurement approach using an SM206 precision digital solar power meter, a digital solar flux meter, and an M890C+ digital Multimeter. The result obtained shows an interesting correlation for current, efficiency and solar power as well as for solar flux which indicates that high solar power and solar flux positively enhances the performance of the photovoltaic. The results also reveal that once the solar power or solar flux reaching the photovoltaic exceeds 200W/m2 or 20Klux, the voltage from the photovoltaic approaches maximum and remains fairly stable irrespective of the amount of solar power or solar flux reaching the photovoltaic. The data collected for three months, July, August and September shows prediction efficiency of 87 %, 63% and 71% at 11:30am, 12:30 pm and 10:30 am respectively.

Performance evaluation of polycrystalline photovoltaic modules in a Guinea Savanna and Mangrove swamp

“…The graphs show that high level of irradiance favours an increase in current, power and efficiency, showing that linear relationships exist between irradiance and current, power and also irradiance and efficiency. Figures 12 to 15 perfectly agrees with studies by [25].…”

Evaluation of the Performance of Photovoltaic System under different Wavelengths from Artificial Light in a Controlled Environment

“…Hence the results obtained with this methodology tends to be free of any uncertainty that may have occurred due to the presence of time lags as noticed in referenced (Kazem and Chaichan, 2016) and (Njok, et al, 2020c). The efficiency of the PV module is greatly influenced by several parameters including design and maintenance of the module and solar power, and may be determined by (1) as shown by (Njok, et al, 2020b), while the normalized power output efficiency and performance ratio was computed by ( 2) and ( 3) respectively as shown by (Ogbulezie, et al, 2020).…”

Design and implementation of an I-V curvetracer dedicated to characterize PV panels

“…The solar cell is a nonlinear device [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and can be represented as a current source model, as shown in Figure 1. In our case, a photovoltaic panel is constituted of 36 solar polycrystalline cells in series (Kyocera LA 361 K51) tilted at 35° angle facing south.…”
