How big is a 15kW solar power system?

A 15kW system using 370W panels will require about 71.9 square meters of roof to be installed. Each 370W panel measures about 1.75m x 1m. 15kW solar power systems are mostly suitable for small businesses with low energy needs. This size of solar power system is classed as "Commercial".

Do I need a 15kW solar system?

Whether or not you need a 15kW solar system will depend on many things. If you are a Commercial customer and you use between 57.5kWhs and 90.6kWhs then a 15kW solar system could be a good choice to help reduce power bill costs. Solar Proof Quotes offer a quick and easy way to get 15kW solar system quotes.

Can a 15kW solar array be put on an inverter?

A 15kW solar array can be put with an inverter with an AC output of 11.25kW. What you "can" do is not what you "should" do. All inverters have different specs. And based on those specs you might be able to put a LOT more panels on than the rated inverter capacity. That does not mean you should.
