Cost ranges for Longmont homes
At $2.80–$3.25/W installed: 5 kW is about $14,000–$16,250, 6 kW about $16,800–$19,500, 8 kW about $22,400–$26,000. LPC doesn’t offer a solar rebate we’ve found, and the federal homeowner credit ended for systems completed after 2025.
Designing for value-of-solar
Under the 2025 rule, self-consumed energy is worth the full retail rate and exported energy is worth less. We model your hourly usage pattern, then size the array so most production is used on site. West-facing panels, which produce later in the afternoon when many households are home, can earn their place here even though they make fewer total kWh than south-facing ones.
If a smaller array plus a battery beats a bigger array on your bills, that’s what we’ll recommend. If neither beats doing nothing by enough to justify the cost, we’ll say that too.
FAQ
Questions we hear
Is solar still worth it in Longmont after 2025?
For many homes, yes — but less automatically than before. Self-consumed solar still offsets retail power; exports earn less. Homes with daytime usage, EVs or heat pumps tend to come out best.
Should I get a south- or west-facing array in Longmont?
South produces more total energy. West can match your afternoon and evening use better, which counts more under value-of-solar. We model both on your roof.
What does a 6 kW solar system cost in Longmont?
About $16,800–$19,500 installed at our $2.80–$3.25 per watt, before any incentives. Lease and PPA options can reduce upfront cost to zero; verify current terms.
