Cost, Savings & Financing
How much can I actually save on my electric bill?
It depends on your usage, roof, and utility rate, but our customers typically see a substantial reduction in their monthly electric bill, and net metering credits push it lower still. Your proposal includes a production estimate and a savings projection specific to your home rather than a generic average.

Incentives & Tax Credits
Is the 30% federal solar tax credit still available?
The federal residential solar tax credit under Section 25D ended for systems placed in service after December 31, 2025. Homeowners buying a system with cash or a loan in 2026 should not count on a federal residential credit. Colorado state and utility incentives still apply, and different rules govern commercial and third-party-owned systems. Talk to your tax professional about your specific situation — and talk to us about what incentives remain in your utility territory.

Roofing
How much does a new roof cost?
Most roofs fall between $5,000 and $30,000. The range is wide because four things drive it: material (asphalt shingle is the most affordable; metal, tile, and slate cost more), roof size, complexity of the labor, and local code requirements. We give a fixed quote after inspecting the roof rather than a per-square estimate over the phone.

Storm Damage & Insurance
Does homeowners insurance cover hail damage to my roof?
Often, yes — hail damage is a covered peril under most Colorado homeowners policies, subject to your deductible and to whether your policy pays replacement cost or actual cash value. Coverage decisions are between you and your carrier. We can inspect and document the damage; your adjuster determines the claim outcome.

Warranties & Service
What warranty comes with a solar installation?
You get a 25 to 30-year manufacturer product warranty on the panels and a 10-year workmanship warranty from us covering anything related to our installation. Because we don’t subcontract, the workmanship warranty is backed by the same company that did the work — there’s no finger-pointing between contractor and installer.

Batteries & Backup Power
Will my solar panels keep working during a power outage?
Not on their own. A grid-tied system without a battery shuts down during an outage — that’s a required safety feature so power isn’t sent onto lines that utility crews may be working on. If you want power during outages, you need battery storage. This surprises a lot of homeowners, so it’s worth deciding up front.

EV Chargers
What’s the difference between Level 1 and Level 2 charging?
Level 1 is a standard 110V household outlet — it works, but a full charge can take 12–24 hours. Level 2 runs on 240V and delivers roughly 12 to 60 miles of range per hour of charging depending on the vehicle and charger. For anyone driving daily, Level 2 is the difference between charging overnight and planning your week around it.

Living With Solar
Do solar panels work in Colorado winters and snow?
Yes. Panels are actually more efficient in cold temperatures, and Colorado’s high number of sunny days is a genuine advantage. Heavy snowfall temporarily reduces production, but panels are mounted at an angle that sheds snow, and the dark surface warms and clears faster than the surrounding roof. Annual production estimates already account for winter.
