20kW Solar Systems

Our 20kW solar system collection features DIY solar kits which will produce at least 20,000 Watts of power. Assuming at least five hours of sunlight per day, this translates to approximately 2,400 kilowatt hours (kWh) of AC power each month.

Choose from a selection of 20kW solar kits with string inverters, microinverters and SolarEdge or Sol-Ark inverters. Both grid-tie and off-grid solar kits are included. Hire a local contractor or install your own 20kW solar panel kit for extra savings!

Frequently Asked Questions for 20kW Solar Systems

How much power can I get out of a 20kW 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. At its highest output, a 20kW solar panel system produces about 20,000 Watts (or 20 kilowatts) of energy.

How many panels does a 20kW solar system require?

The number of solar panels required to generate 20 kilowatts of energy hinges on the efficiency of your panels. Typically, you would need about 55 to 60 panels, but GoGreenSolar solar panels can do the job with 50 panels.

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

A 20kW solar kit requires over 1,150 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.
