How much power do you actually use?
Solar systems are sized in 1 kW - 20 kW (and larger) systems. A typical residential size is 4 kW.
4 kW, or 4 kilowatts = 4,000 watts
A 4 kW system will generate around 4,000 DC watts per hour
Multiply the per hour generation by 5.4 which is an average number of sun hours in a day (4,000 x 5.4 = 21,600)
Multiply the new total by the average number of days in a month (21,600 x 30.5 = 658,800)
Multiply the new total by .77. This is the "derating" factor, or the amount of energy lost when DC current is turned into AC current. (658,800 x .77 = 507,276)
So, a 4 kW system will generate about 507,276 watt-hours per month, or about 507 kWh.
Now compare this number with the kWh usage noted in your electric bill. How many kWh do you use in a typical month? Twice this amount? Then you would save roughly 1/2 your electric bill if you installed a 4 kW system.
Consider how much money you save per month to figure out how long it will take to pay off your system.
The most productive system is located on a South- or West-facing roof (or area) that is shade-free from 9am-3pm every day of the year.
