What does Project Solar cost? It posts the whole list
Project Solar’s Texas list starts at $2.15 a watt, plus a size charge and a $10 fee. An 8 kW system comes to $18,810 before incentives.
Most solar companies hide prices until a sales visit. Project Solar does the opposite. Its price list shows the base price, the size charge, battery prices and every add-on. Smaller systems cost more per watt. That is because the size charge drops as systems get bigger.
Build a Project Solar price, the way its price list does
These are Project Solar’s own Texas numbers. Pick your size and extras to see the total before incentives.
From Project Solar’s Texas price list dated October 5, 2026. Systems under 4 kW add $1,000. Other add-ons, like travel fees, extra roof planes or the 1.9% PayKeeper fee, are not shown. Your final quote may differ.
Its homepage also says prices start “as low as $1.61 a watt.” That figure is for other places or bigger systems. For Texas, use the price list.
Its October 5, 2026 price list is the same in Arizona, California, Colorado, Florida, Nevada and Texas, so this calculator works for all six.
The catch: a partner company installs your system
Project Solar sells the system online. Then one of its partner companies puts it on your roof.
Its warranty terms say each system is “installed by one of our preferred partner installers.” So the company you buy from is not the crew on your roof. In our formula, that costs all 12 points for who installs.
Here is why it matters. In one 2026 complaint, the partner company went bankrupt, and the project sat unfinished for months. Project Solar says it backs the install warranty if a partner fails. Still, before you pay, ask which partner will do your job. Get its name and license number in writing.
Why Project Solar is not in our Texas ranking
Its Texas electrical contractor license, EC-37910, expired on March 28, 2026. We only rank companies with an active license.
Texas still appears on its price list, so it may still sell there through partners. If you are in Texas, ask Project Solar for a current license or seller registration number. Then look it up on the state’s license search before you sign.
How Project Solar scores 67
Its warranty and clean legal record scored well. Partner installers, missing certifications and a stale tax-credit claim cost the most.
Project Solar missed 33 points. Partner installers cost 12. No NABCEP or equipment-maker certification cost 6. Loan fees not shown cost 5, and the stale tax-credit claim cost 4. No outside warranty backup cost 3. Its B- grade cost 1, and being six years old cost 2.
Every company gets this same formula, built from public records. Project Solar pays us nothing, and ads never touch a score.
A strong warranty, including a power promise
Project Solar covers workmanship and roof leaks for 10 years. It also guarantees how much power your system will make.
The production guarantee is rare. Project Solar promises a set amount of power each year. The promise drops 5% after year one, then half a percent a year, for up to 25 years. If you come up short, it pays 15 cents for each missing kilowatt-hour, once a claim is approved. Its terms aslo say there is no savings guarantee.
Equipment warranties come from the makers, with Project Solar as your contact. Panels carry 25 years. The warranty can move to a new owner if you give written notice within 20 days.
A stale tax-credit claim on its homepage
Project Solar’s homepage says homeowners can still benefit from the 30% tax credit. For people who buy, that credit ended on December 31, 2025.
Its add-ons page also says your true cost will be 30% less. Yet its own October 5, 2026 price list assumes no tax credit at all. The mixed message cost Project Solar 4 points for honest tax-credit claims.
The lesson is simple. Use the price list, not the homepage, and leave the 30% out of your math. If anyone tells you the credit still applies to a purchase, ask them to show you the law in writing.
A B- grade and a warning about price claims
The BBB gives Project Solar a B- because it did not answer 2 complaints. The BBB also flagged its “lowest price” ads.
On December 31, 2024, the BBB asked Project Solar to back up, change or stop “lowest price” claims on its website and signs. As of January 10, 2025, it had not, the BBB says. Its file shows 18 complaints in three years, and the BBB publishes 13 of them.
We read all 13, from October 2023 to August 2026. Project Solar answered 11. Slow replies came up in 10. One customer waited about seven months for return labels on a failed generator. Money problems came up in 7. One customer said they were still waiting on about $32,000 after an install stalled.
Complaints cost points in our formula only when the BBB flags a pattern. This file has an ad notice, not a complaint pattern, so the B- grade is what counts.
33 states, plus D.C. and Puerto Rico
Project Solar’s install-area page lists 33 states plus D.C. and Puerto Rico. A second list on the same page shows 32.
The two lists on its install-area page disagree on Idaho, Utah and Michigan. Its power-purchase plans reach 18 states, and a do-it-yourself kit is sold in most of the lower 48. Its price list covers only Arizona, California, Colorado, Florida, Nevada and Texas.
Ask Project Solar to confirm it serves your address before you pay anything. And check the partner installer’s license in your state.
