Reasons to look at others

It does not say how you can payIts site lists no way to pay: no purchase, loan, rent or PPA plan. All three alternatives below list theirs. Ask which plans TerraSol offers and who would own the panels.
Its panel brand may be out of dateIts FAQ names SunPower panels. SunPower filed for bankruptcy in 2024. Ask which panels your quote uses today and who backs their warranty.

TerraSol Energies 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 clear explanations of permits, utility approval, net metering and solar credits, no sales pressure, and respectful, tidy crews. The one negative review, from 2018, describes a fine installation followed by two years of unanswered calls and emails about follow-up work, with only one visit. These are issues to ask about, not a measure of how often they happen. Ask TerraSol who handles follow-up service after installation and how quickly it responds.

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 (181 reviews read, back to Feb 13, 2017). We found no Trustpilot page for TerraSol Energies 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 TerraSol Energies cost?
TerraSol does not publish a system price or payment plans on the pages we reviewed; it offers a free estimate. Ask for an itemized quote showing the cash price, system size, equipment models and any financing it can arrange, with the financed total, APR and fees. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.
Payment options not listed
Ask the companyThe site lists no purchase, loan, lease or PPA terms. Ask which plans it offers and who owns the system under each.
We found no payment plans on TerraSol’s residential page or FAQ, read October 13, 2026.
TerraSol’s FAQ says it installs SunPower Helix panels. SunPower filed for bankruptcy in 2024, so ask which panel brand your quote uses today and who backs its warranty. TerraSol also offers solar maintenance, including performance monitoring. 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).
What does TerraSol Energies’s warranty cover?

Where does TerraSol Energies operate, and which licenses were checked?
TerraSol’s about page says it has served Pennsylvania, New Jersey, Delaware and Maryland since 2009 from its base in Chadds Ford, and its homepage title names Chester and Delaware counties in Pennsylvania (read October 13, 2026). A listed state does not mean every address qualifies or that EcoGen can connect you with TerraSol there.
