hello
we want to build a simple off grid solar set up for a small farm house to run some led lights and keeping some simply 12v and 5v devices running a few hours a day.. we found a good deal on two 100watt 24v panels. the label on the panels say that they have a 5amp rating.. so according to our calculations 5amps/h * 5 sunhours per day= 25amps per panel per day.. 2 panels would be 50amps @ 24v.. if we only need 12v does this mean that we would have 100ams? our base of this idea is amp * volt = watts and watts / volt = amps so that would be 50a * 24v = 1200w /12v = 100a? would this be correct?
