Last 6 months: 2 reviews, 1 negative. ## The honest read Helio Solar's website describes solar, batteries, heat pumps, roofing and electrical work designed as one system. A 2026 post on r/Connecticut placed Helio Solar in Trumbull. It holds a 4.4-star Google rating from 43 ratings. A recent customer describes an 18.275 kW system with 43 panels on a roof with many faces, and says the company coordinated with them and their contractor and cared about how the conduits were positioned and run. A recent 3-star review says the install went smoothly, with no hardware issues and installers who left their work areas clean. That customer also says it took 2.5 weeks of following up after the utility rejected the proposed drawings before Helio responded. That customer says the company received their incentive payment in January 2026 without their knowledge, and a check was written to them in June 2026 after months of emails and calls. A 2026 customer described numerous meetings to add options such as a critter guard and a hybrid inverter, and said the panels went on in a day while the permits took much longer. A 2025 customer said Doug set reasonable expectations, and that when there was some property damage on the exterior of the house, Helio fixed it in an expedient fashion. A 2023 customer said the company spent a few hours and two trips fixing their air conditioning, which had nothing to do with the solar power, and that Nick ran out to buy them a new thermostat. A 2024 customer had a car charger installed for their electric vehicle. In a 2024 one-star review, a customer said the installation took 3 months longer than initially promised, that answers to questions took weeks, and that Helio did not allow owners to adjust the time-of-use settings on their Sol Ark battery. **Strengths:** - A complex roof layout — a recent customer describes 43 panels on many roof faces - A clean install site — a recent customer says installers left work areas clean - A damage repair — a 2025 customer said exterior damage was fixed quickly **Concerns:** - Slow communication — a recent customer says a response took 2.5 weeks - An incentive payment — a recent customer says it was repaid months later - Battery settings access — a 2024 customer said owners could not adjust them ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Its website describes solar, batteries, heat pumps, roofing and electrical work designed as one system _(confidence: medium)_ - [Official Website](https://www.helio.solar) — “About (self-reported, verbatim): Solar, batteries, heat pumps, roofing, and electrical — designed as one system so you make your own power, …” - 4.4-star Google rating from 43 ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Helio%20Solar&query_place_id=ChIJW-RUaBQL6IkRP1M2pY8LF_E) — “Google: 4.4★ from 43 ratings” - A recent customer describes an 18.275 kW system with 43 panels on a roof with many faces _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT21SSFVUZFBaWHBzVFVwaWNYa3RRM2RFUVd0dE9HYxAB!2m1!1s0x0:0xf1170b8fa536533f!3m1!1s2@1:CAIQACodChtycF9oOmRHUTdPZXpsTUpicXktQ3dEQWttOGc%7C%7C?hl=en-US) — “5★ We were very happy with Helio solar.
