8kW Solar Panel Systems: How Much Do They
On average, an 8 kW solar panel system costs $20,720,
An 8 kW solar panel system will produce an average of 700 to 1,400 kWh of electricity per month, depending on your exact home and where you live. One of the biggest factors in how much energy solar panels produce is the amount of sunlight your roof gets.
Moreover, you can also play around with our Solar Panel Daily kWh Production Calculator as well as check out the Solar Panel kWh Per Day Generation Chart (daily kWh production at 4, 5, and 6 peak sun hours for the smallest 10W solar panel to the big 20 kW solar system).
8 kW solar panel systems generally use between 20 and 22 solar panels and require about 390 square feet of roof space. The number of solar panels you need for an 8 kW system depends on the power rating of the panels. For example, you would need about 23 panels if you used 350 watts.
Larger installations like a 10 kW system (about 25 panels) produce approximately 10,000–15,000 kWh annually, enough to power even energy-intensive households. Sizing your system correctly is key. A professional solar installer can match the system capacity with your household's energy needs to maximize efficiency and savings.
