I want to light one 70watt bulb for 12 hours at night time. I want to know what should be the Watts of the solar panel and how much Ah battery will I require?
I searched many of the questions here and found this one relevant. But the question is how will I know the volts which you assumed here to be 12 V?
May I know if I have done the right calculation as below
Panel Watts req = 70 * 32 / 10
Assumed 12V, Battery Ah= 70W / 12V * 12h = 70Ah
