How much solar power for a 2hp motor to run continously?
I saw the solar charged lawn mower but I was wondering how much solar panel footage would you need for it to just run and run with no battery, but still cutting like a smallish push lawn mower?
2HP is 1.5kW. Allowing for inefficiencies, that is 2kw. At 12 volts, that is 170 amps!
10-watts per square-foot for peak output is a common number for arrays. for 2000w, you will need 200 square ft! That is an area 14' by 14'.
And you have to keep it pointing directly at the sun as you mow.
