20kw on grid solar system specification
The 20kw on grid solar system can produce between 2500kwh and 3500kwh of electricity per month, which is more than enough for a small factory, commercial house. The required PV panel installation area is 100m².
In the case of abundant sunlight, string grid-connected inverters produce more power than off grid inverters and hybrid inverters. It is important to note that the area where the panels are to be installed must not be blocked by sunlight such as chimneys, large trees, buildings, etc., in order to ensure that the overall efficiency of the system is maximized.
