For the three quotes everyone tells you to get

Compare solar quotes side by side

Enter two or three quotes, whether a lease, a PPA, a loan or a cash price, and see them ranked by what each kWh of solar power really costs you over the deal. Warnings for each quote are listed below the ranking.

How to compare solar quotes

Cost per kWh is the fair yardstick. A lease, a PPA, a loan and a cash price can't be compared by their monthly payment or their headline price. We add up everything you'd pay over the deal (payments, interest, escalators, and for a system you own, a replacement inverter) and divide by all the power the panels would make. The lowest number wins.
Check the production estimates. A quote that promises more power per panel looks cheaper per kWh. If a quote's estimate is well above your state's average, we flag it: ask how they got it. If quotes leave it out, we use your state's average for all of them.
Look at the total too. A bigger system or a longer contract can save more in total while costing more per kWh. When the cheapest per kWh isn't the one that saves the most, we say so.
Batteries change the math. A quote with a battery costs more per kWh of solar power, but the battery moves power to your evenings. Compare its savings, not only its cost per kWh.
Price isn't everything. Before you pick, check each company (license, who installs, warranties) and go through the contract checklist.

Assumes electricity prices rise 2.5% a year and panels lose 0.5% of their output a year, with no federal credit for buyers in 2026. How the numbers work.
