How It Works

Electricity rates have increased an average of 2-4% per year historically. At 3% annual increases, a $0.14/kWh rate becomes $0.29/kWh in 25 years. Solar locks in your energy cost at installation. The gap between rising grid rates and fixed solar cost widens every year, making solar more valuable over time.
