Description Solar cash allows customers to forgo monthly payments and pay for their system in full. Solar loan customers pay a fixed monthly payment and an interest rate with the option of a 10-, 15-, or 20-year term. Signing a solar lease allows customers to pay a set monthly fee for solar energy over 10 years.
Cost Full cost of system Set monthly payments Set monthly payments
Pros Immediate return on investment, increase in property value, and available tax incentives Zero money down, zero payments for the first 90 days, and three term options Customers don’t pay for installation
Cons Requires a one-time payment equal to the full cost of the system Calls for monthly payments that include a set interest rate Customers don’t own their system, have no choice in installed equipment, and forfeit potential tax incentives

Frequently Asked Questions About Sunergy

How much roof space will my system need?

Sunergy recommends 80 square feet of roof space for every 1,000 watts of solar modules. The average size of a system ranges between 5,000W and 8,000W, so the required roof space is between 400 square feet and 700 square feet.

Can I sell power back to my utility company?

Yes. With net metering, any excess energy your system produces will go to the electrical grid and result in your utility company awarding you credits towards your total utility bill.

Is there any required system maintenance?

It’s recommended that you clean your solar panels annually with soap and water.
