6.88 kW Installation for Homeowner in Southern Illinois

pic 1 (1)

This Southern Illinois homeowner kept it simple and smart with 16 Q-Cell 430W panels on the roof paired with a Tesla Powerwall 3 for backup power when the grid can’t deliver. The compact 6.88 kW system is projected to generate 185,962 kWh over 25 years, offsetting over 354,000 lbs of CO2 and the equivalent of more than 409,000 miles worth of driving. Proof that you don’t need a big system to make a real difference.
