Question 1

How many kW of solar can I install on a parking lot?

Accepted Answer

Surface-lot solar canopies typically install 350-400 watts per parking stall covered. A 200-stall lot supports 70-80 kW; a 1,000-stall lot supports 350-400 kW.

Question 2

What does a solar parking canopy cost per kW?

Accepted Answer

Installed costs run $2.80-$4.20 per watt for parking canopy systems — about 30-40% more than rooftop solar. A 100 kW canopy is $280K-$420K turnkey before incentives.

Question 3

What is the federal Investment Tax Credit for solar?

Accepted Answer

The federal ITC covers 30% of total project cost for projects starting construction through 2032, then 26% in 2033 and 22% in 2034. Bonus 10% applies in qualifying low-income or energy-community areas.

Question 4

How fast does a solar parking canopy pay back?

Accepted Answer

Simple payback runs 8-12 years. With 30% ITC and 60% MACRS bonus depreciation, after-tax payback drops to 4-7 years. Pairing with EV charging or premium covered-parking pricing drops payback below 5 years.

Question 5

Can I lease the canopy via a Power Purchase Agreement?

Accepted Answer

Yes. PPAs require zero capital — a third-party developer takes the tax benefits and you buy power at a fixed rate below grid pricing for 20-25 years.
