Cost of Solar Energy
When deciding whether to go solar, many people hesitate because they think the solar power cost will be too high. While you do pay for a solar installation up-front, you can expect to recoup your initial expense through monthly utility savings. Once you've realized this return on investment, you will begin to save money. Our ROI calculators will show you how long it would take to pay off the cost of solar energy installation before your monthly savings begin.
To determine how much you could save by going solar, locate the past 12 months' utility bills and add up the amount spent on electricity and the amount of electricity consumed in kilowatt hours. Enter in your zip code to see a calculation of how much you could save in one year by switching to solar energy. To learn more about the savings you'll see by going solar, use a ROI calculator here.
Solar Panel Financing
If you cannot afford to pay for solar energy up front, consider solar panel financing. Pay a low up-front fee or choose an option that allows for zero down, then make monthly payments. Alternately, you can sign a power purchase agreement and pay a low monthly rate for generated solar power. Learn more about solar financing here. Qualifying solar water heaters and solar panels are also eligible for a federal green tax credit. These tax incentives are available for new or existing primary or secondary residences, but are not available for solar rentals.
