Kwh of energy/month? PV solar panels are sold by the 100w, 1000w etc. I know the energy I use per month in Kwh. What does the 100 watt solar panel rating mean? How do I calculate how much energy in Kwh I can get from a 100 watt panel in one month? This must require information about the average sunlight in my region in that month. Where can I find that information and how is it used to calculate the actual monthly production in Kwh per 100 watt rated panel?
