THE SUNMATE COMMERCIAL SOLAR HEATING SYSTEM - 30% FEDERAL TAX CREDIT

WHY INVEST IN SOLAR HEATING?

High return on investment: Up to 10.5% after Federal rebate

Higher Efficiency: from October 1 to April 30, SunMate solar hot air panels can collect up to 24.6 kWh per square foot

Cost Less to Install: An average of $2.44 per watt, $1.70 after Federal rebates

Greener Choice: Less solar panels needed to collect the same amount of solar energy, less cost to install

South Facing Wall Installation: No issues with drifts of snow covering panels resulting in no power loss

Environmental Solar Systems has 25 years years of solar experience
