Solar Alliance Review
Commercial solar builder that also offers home systemsResidential work unconfirmed since the May 5, 2026 cease trade orderBased in Knoxville, TennesseeProfile updated October 15, 2026
Is Solar Alliance a good choice?
Solar Alliance is mainly a commercial solar builder; its homepage focuses on businesses, churches, utilities and community solar. Its home solar page centers on pre-engineered Sunbox systems for builders and developers, with custom home designs on request. Its parent company could not file audited financial statements on time, and the British Columbia Securities Commission issued a cease trade order against it on May 5, 2026; the order was still active on October 13, 2026, and the TSX Venture Exchange suspended its shares (company release, TSXV bulletin). Its last release naming 2026 work lists only commercial and municipal projects, so its residential work is unconfirmed since the order. Homeowners should ask about warranty terms, payment plans and who services the system.

Why choose Solar Alliance, and why you might not
What Solar Alliance does well, and where to be careful, compared with the installers it competes with most.
Reasons to choose Solar Alliance
It builds large business projectsSolar Alliance mostly builds solar for businesses, churches, power companies and shared community projects. It also helps farms and non-profits apply for a federal grant.
It offers ready-made home systemsIts home systems, called Sunbox, come in three set sizes and are aimed at home builders. It also does custom home designs on request and puts in EV chargers.
We found an active Kentucky licenseWe found an active Kentucky license for Solar Alliance when we checked on October 13, 2026. Its site prints no license numbers, so ask for them.
Some owners praise its crewsIts good reviews praise skilled crews and neat installs. One owner says a recalled part and a failed control box were fixed quickly.
Reasons to look at others
Its parent company is in trouble with regulatorsIts parent company did not file audited financial reports on time. A Canadian regulator ordered its shares frozen on May 5, 2026, and the order still stood on October 13. Ask who will back your warranty if the company changes.
Its Tennessee license was not activeIts Tennessee license showed inactive or expired when we checked on October 13, 2026. Ask for a current Tennessee license before you sign.
It lists no warranty and no way to paySolar Alliance publishes no warranty, no home payment plans and no equipment brands. Of the three alternatives below, LightWave lists 5 years on its own work. Get all of this in writing.
Many owners report unanswered callsFour negative reviews describe weeks or months of unanswered calls and emails, some about systems that did not work. Ask who answers service requests today.
Solar Alliance reviews: what customers say
Each review site shows its own score; we read them on October 12 and 13, 2026 and do not combine them or add our own rating.

The five positive reviews below praise knowledgeable, skilled crews and neat installs, and one says a recall and a failed controller were fixed promptly. Of the five negative reviews, four describe weeks or months of unanswered calls and emails, including about non-working systems and missing warranty details, and one is a shareholder’s complaint, not a customer’s. These are issues to ask about, not a measure of how often they happen. Ask Solar Alliance who answers service requests today and how warranties pass to a new homeowner.

How we picked these: the five newest 5-star and the five newest 1- or 2-star reviews with written text on Google and Trustpilot, as of October 2026 (28 reviews read, back to Apr 24, 2018). We found no Trustpilot page for Solar Alliance on October 12, 2026. Each quote is one sentence, word for word. Picking the highest and lowest ratings shows the range of experiences; it is not a representative sample, and we did not verify what reviewers describe.
How much does Solar Alliance cost?
Solar Alliance does not publish a fixed system price; its home solar page gives only an old starting figure and describes the federal tax credit as current. The federal residential credit ended for systems placed in service after December 31, 2025, so leave it out of your math. Ask for an itemized quote showing the cash price, system size, equipment models and forecast production. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.
Payment plans
Ask the companyNo residential payment plans are listed. The site mentions USDA REAP grant help and federal incentives for businesses and nonprofits.
Based on Solar Alliance’s home solar page and FAQ, read October 13, 2026. No loan, lease or PPA is listed for homes.
Solar Alliance does not name the panel, inverter or battery brands it installs on the pages we read. Its home solar page describes Sunbox systems engineered in three typical sizes, plus EV chargers and custom designs. Your written proposal should list the exact panel, inverter and battery models, the system size in kilowatts (kW) and the forecast yearly production in kilowatt-hours (kWh).
