How the work is coordinated
No Tesla-certified-installer claim is made unless a grounded source states it. Denver-metro work is permitted locally. Colorado has no statewide general-contractor license. Cities and counties license general contractors. DORA licenses electrical and plumbing (and similar regulated trades), not general contractors. Autotelic is a municipally licensed Denver general contractor that coordinates licensed specialty trades. Denver building permits run through Community Planning and Development (CPD). Costs are project-specific; no dollar figures.

FAQ
Common questions
How much does Home Battery / Energy Storage Assessment cost in Longmont?
$199.
How do I book?
Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.
What's not included?
Battery hardware and installation labor are not included.
What changed with the federal tax credit in 2026?
The federal residential clean energy credit expired for systems placed in service after December 31, 2025, so homeowners who pay cash or finance with a loan in 2026 receive no federal credit. Some installers still advertise the old credit; we do not. Leased or PPA systems still capture roughly 30% through the section 48E credit (through 2032), passed through by the lessor.
What will a Powerwall run during an outage?
It depends on which circuits are on the protected loads. A single Powerwall can keep essentials like lights, refrigeration, outlets, and a gas furnace running for many hours, but running an entire home for a long outage requires enough battery capacity for your specific loads. We model this during design so the system matches your expectations.
Does a Powerwall require solar panels?
No. Powerwall works as a standalone backup battery charged from the grid, so solar is not required for outage protection. Adding solar lets the battery recharge during the day and extends backup coverage, but it is optional.
How do the permit and Xcel interconnection work?
We pull the municipal electrical permit and submit the Xcel Energy interconnection application on your behalf. After installation, a municipal inspection and Xcel approval are required before the battery is given permission to operate and activated.
Who qualifies for Xcel Energy's Renewable Battery Connect rebate?
Xcel Energy customers with qualifying battery systems may be eligible for $350 per kW, up to $5,000, with income-qualified customers eligible for $800 per kW. Rebate amounts depend on program-year funding availability and the program rules in effect when the application is submitted.
