- Working conditions were simulated by forward biasing the 1 mm2 solar cells at the same current level (250 mA, i.e. 25 A/cm2) they would handle at the operating concentration (i.e. 1000 suns)’
It is demonstrated that the relationship between current flow and irradiance in a photovoltaic circuit with zero bias voltage can be simulated by the equation,
I = Im tanh (αH/Im) + βImH + γIm,
where Im is the maximum photocurrent, H is the irradiance, and α, β, and γ are constants. This study ,to investigate the relationship between solar radiation (flux) and current, voltage, solar radiation and efficiency of solar panel, in location (Oman ). Solar Radiation (flux) measurements as well as formal meteorological data were utilized. Data were recorded from the digital instruments used. Analyses were made between solar radiation (flux) and current, voltage and efficiency.
The Results obtained show that there is a direct proportionality between solar flux and output current as well as solar flux and efficiency of solar panel. This implies that an increase in solar flux leads to increase in output current which enhances efficiency (performance) of a solar panel.
Result
The solar panel was of crystalline silicon type with surface area of 0.19m2 and capacities of 9.0V and 2.5A, respectively.
