Using 4 hours of full sun, gives you this equation: 250 watts x 4 hours. Thatâs 1 kWh (1,000 watts) in a day per 250-watt panel. If you multiply 1kWh per panel by 30 days in a month, youâll find that each 250 watt rated panel will produce about 30 kWh in an average month.
Left on for 10 hours, it will consume 1000 watt-hours, which is the same as 1 kilowatt-hour, or 1 kWh. Similarly (and under ideal conditions), if a 345 watt solar panel is left in the brightest sun for 1 hour, it will generate 345 watt-hours of energy.Under those same ideal conditions, after three hours, it will generate a little over 1 kWh.imilarly (and under ideal conditions), if a 345 watt solar panel is left in the brightest sun for 1 hour, it will generate 345 watt-hours of energy.
