Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
