Frequently Asked Questions About 15kW Solar Systems

How much power can I get out of a 15kW Solar System?

Variables like weather, temperature, the age of your system and whether your panels are heavily soiled can affect how much power your solar system can produce. Generally, if you account for these system losses, a 15kW solar system produces about 12.9kW of energy. 

How many panels does a 15kW solar system require?

The number of solar panels required to generate 15 kilowatts of energy hinges on the efficiency of your panels. Typically, you would need about 50 to 60 panels, but GoGreenSolar panels can do the job with 38 panels.

How much space will the solar panels take on my roof?

A 15kW solar kit requires over 874 square feet of space. Solar panels with string converters need to be grouped together and facing the same direction. You’ll want to consider whether this option is the right choice for you or if you’d be best served by solar panels with microinverters. Microinverters allow you to place panels in various locations, directions and angles on your roof. If space is at a premium, this choice will offer you more flexibility.
