Solar Panel Efficiency?
200 watt solar panel generates how much watts of electricity per month?
I've operated a 25 kilowatt (kw) solar panel system for two years (144 panels, rated at 190 watts each, just about like yours). It averages 110 kilowatt hours (kwh) per day, but clear days get about 160 kwh. My system generates about 3300 kwh per month (we dump directly to grid), worth about $4,000 per year. Payback for my system, which cost $100,000 (after utility rebates and tax credits), is 25 years (the expected lifetime, coincidentally). Under similar conditions, your 200 watt solar panel would average 820 watt-hours per day, or about 25 kwh per month, worth $2.50.
