The sun’s output power is given as 1000 W/m2. The solar module has a surface area of 1 m^2 with a conversion efficiency of 10%. A charge controller converts the 20V module voltage to 12V battery voltage, with an efficiency of 84% The battery is 12V with a capacity of 10Ah. Assuming the battery is half empty and the bulb is powered on, how long will it take for the battery to be fully charged? How long can the bulb be powered at night, assuming full battery when the sun goes down and that you can fully drain the battery
