For perspective, according to the EIA, the average American household uses 10500 to 11000 kWh of energy per year. This amount of energy translates to about 900 kWh per month or 30 kWh of energy per day. In other words, a 4kW solar system would only be able to offset about 50% of the energy consumption of the average U.S. household.
The exact number of solar panels that you need to make up a 4 kW solar system will depend on the Power rating (Wattage) of the solar panels you plan on using. For example, if you use 200 Watt solar panels, you’ll need 20 solar panels to make up 4000 Watts (4000W ÷ 200W = 20).
A 4kW solar system would require between 190 and 260 sq. ft. (21 to 24 sq. m.) of roof space depending on how efficient the solar panels are. The more efficient the solar panel used in the 4kW system, the less space will be needed.
Mini-split systems are most efficient. A 12,000 BTU unit requires about 1.5kW solar and 10kWh battery per day of operation. For central AC, you’ll need a large system (10kW+ solar, 30kWh+ batteries) plus generator backup. How long do off-grid solar systems last?
