A tesla solar roof costs 22 to 45 per square foot which includes the solar roof tiles a powerwall roof and site repairs and complete system installation. Here s a general example. System size kw square footage needed for low efficiency 16 square footage needed for medium efficiency 18 square footage needed for high efficiency 22 5 kw.

Household is a 6 62 kw solar system to match the 9 000 kwh of average energy usage by u s. Tesla solar roof cost. How many solar panels do you need for a 2000 sq. Most residential solar panel systems use between 250 325 watt solar panels.

Ft so most homeowners will have more than enough room for solar panels. For example if the amount of power needed is 5 000 watts and each shingle is rated at 50w you need 100.
