Bill reality (rough estimate)

From your proposal summary, often 90 to 110%.

6 quick questions about your solar financing terms

Question 1 of 6

Does the proposal show a cash price (not just monthly payments)?

A legitimate quote always includes the total system cost before financing. If you only see monthly payments, the true cost may be hidden.

FAQ

Why is my bill not $0 when the proposal says 100% offset?

Fixed charges, minimum bills, demand charges, and how credits apply to leftover usage all sit outside a simple offset percentage.

Are dealer fees normal on financed solar?

Common, but they should be disclosed. Compare cash price to total financed payments, not just monthly payment.

What's the difference between a solar loan and a PPA?

A solar loan finances equipment you own. A PPA (Power Purchase Agreement) means a company owns the panels on your roof and sells you the power. PPAs often have annual escalators and complicate home sales.

Should I worry about 0% interest solar loans?

Usually. True 0% financing is rare. Most '0% interest' solar loans include a dealer fee (15-30%) baked into a higher system price. Compare the cash price to the financed price to see the hidden cost.
