Rebates & savings
Programs that may apply. Confirmed on the visit.
Each state runs its own utility and state programs, and they change more often than anyone would like. We put only what you can actually claim into a quote — then an advisor confirms eligibility in your home. Commercial projects are a different path — see commercial.
Residential Clean Energy Credit (25D) — Expired. The 30% homeowner credit for solar, batteries, and geothermal ended for expenditures made after December 31, 2025 — which the statute measures from the day installation was completed, not the day you paid. Paying early did not preserve it. Helio does not apply it to 2026 residential purchases.
Energy Efficient Home Improvement Credit (25C) — Expired. The heat-pump and envelope credit for homeowners also ended December 31, 2025. 2026 HVAC quotes use state and utility rebates only.
One thing to read this page with. Everything below goes to whoever owns the system. If you buy it, that is you. Under a lease or a power purchase agreement the tariff credits, the certificates and the tax credits belong to the company that owns the equipment — which can still be the right deal, but it is a different one.

Claimed by the owner, never by you
Commercial 48E Investment Tax Credit
The credit that survives — and it is never a line on your 1040. On a lease or a PPA the system owner claims it and prices it into what you pay. How long a system has to be built depends on when its equipment was safe-harboured: equipment committed before the end of 2025 carries eligibility through December 31, 2029 and is exempt from the federal sourcing rules, while a project starting fresh today has to be running by December 31, 2027. That gap is the reason third-party ownership can still carry a federal benefit in years when buying the system outright carries none — and it is a finite runway with a date on it, not a permanent feature. Ask any provider which of the two applies to your system, and get it in writing.
