Step 1: REDUCE OR ELIMINATE YOUR ELECTRIC BILL
By creating your own clean solar energy, you can reduce or completely eliminate your electric grill. We typically see an average of a 7-9 year return on investment.
With 25-year manufacturer warranties on all of the system’s major components, you can be assured that your system will continue to produce clean power for years to come.
Step 2: PROTECT YOURSELF AGAINST RISING UTILITY RATES
New England has some of the highest electricity costs in the continental US. The cost of electricity is constantly rising and will never stop.
When you create your own energy, you are no longer subject to your utility companies’ fluctuating rates. Solar payments are fixed and easier to budget.
Step 3: PROTECT THE ENVIRONMENT
In a world with increasingly finite natural resources, it’s up to all of us to do our part. Purchasing a solar array is not only a great investment, but it also lowers your carbon footprint.
To date, our systems have produced more than 20,000,000 kWh of clean energy! That is the equivalent to the carbon emissions from 1,500,000 gallons of gasoline, 16,000,000 lbs of coal, or 32,000 barrels of oil.
