Home Solar Cost Guide

What Colorado pays for your exported solar power

Export compensation is the single biggest payback lever in 2026. Here is Colorado's current rule in plain words, with the official source.

Under Colorado's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for Castle Pines homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

Castle Pines, Colorado has about 15,162 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

The honest 2026 answer for Castle Pines: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Colorado's export compensation, covered in the net metering section.

Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Colorado rules that decide your payback

RuleColorado status
Export compensation (net metering)Colorado requires investor-owned utilities to offer net metering: under PUC Rule 3664 (4 CCR 723-3), excess generation is carried forward month to month and credited at a 1:1 ratio against the customer's retail kWh consumption, with any accrued excess credits compensated within 60 days after each calendar year at the utility's average hourly incremental cost of electricity supply, unless the customer makes a one-time written election to roll credits forward indefinitely.
State incentiveColorado Sales and Use Tax Exemption for Components Used to Produce Energy from a Renewable Energy Source (Sec. 39-26-724, C.R.S.); utility rebates may also apply.
Sales tax on the systemExempt
Property tax on added home valueExcluded

A Colorado net-metered system may be sized to supply no more than 120 percent of the customer's average annual electricity consumption at the site, and unless the homeowner files a one-time written election to keep rolling credits over, leftover credits are cashed out each year at the utility's average hourly incremental cost - well below the retail rate the credits were originally worth.

Common questions

How long do solar panels actually last?

Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.

Should I lease, get a PPA, or buy?

Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.

How do I check if a solar quote is fair?

Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.

What happens if my installer goes out of business?

Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
