The term 20 kW solar panel system refers to the system's total power output capacity. A kilowatt (kW) is a unit of power that describes how much electricity a solar array can generate at any given moment under ideal conditions. In practical terms, a 20 kW system can produce a substantial amount of energy, enough to power a large household or small commercial facility. However, the actual energy generated can fluctuate based on various factors, including panel orientation, shading, and, importantly, the physical size of the solar panels themselves.


Technicians usually install a distributed solar PV system on the rooftops of homes or businesses. These solar power systems generate electricity to offset the property owner’s usage and send any excess production to the electric grid.
