If the photovoltaic panel considered converts the incident s

If the photovoltaic panel considered converts the incident solar radiation to electricity at an efficiency of 11%, what is the difference in power delivered by this panel to a 1.2kW load if the photovoltaic panel is 1m by 2m?

Solution

area of the panel=1*2=2 m²

efficiency is output per given area, here are =2m²

1.2*10³ (11/100) =output power / 2

output power=22*1.2*10³/100= 264 W m² =264/2=132W

difference in power= 1200-132= 1068W
