Here’s what you’ll need to estimate your number of solar panels:
Your average energy usage per month. The average Florida home uses about 1,110 kilowatt hours (kWh) in electricity per month. The average price per kWh was $.117, so the average bill was $130.51.
Your roof size and capacity to support solar panel racking equipment.
The energy efficiency of the solar panels and solar equipment.
The solar panel size.
The average solar panel cost in the system.
Your best bet is to consult an experienced solar installer who can give you a free solar installation quote.
