About How to choose the size of rooftop photovoltaic panels
Statistics showthat most people consume more electricity during the summer and winter, when the A/C or heat is running. If possible, collect your last 12 months of electric bills, then tally up your kWh usage and divide by 12 to get a monthly average.
Next, divide your monthly kWh usage by 30 to estimate your average daily kWh usage. The average American home uses about 900 kWh per month, so we’ll use that in our example: 900.
Sunlight availability affects how much energy your solar panels generate. Use NREL’s GHI maps to see how many sun hours you can expect to get in your location. Below is NREL's.
Most grid-tie homeowners choose to offset 100% of their energy needs with solar. But it is also possible to start with a smaller system for partial offset.
From there, we need to add a bit of overhead to account for inefficiencies and degradation rate of the panels.
