Size to daytime use
A kWh you use as your panels make it saves the full retail rate; a kWh you export earns the lower value-of-solar credit. We start with your interval data from LPC’s meter and size the array to cover what the home actually uses during daylight, plus planned daytime loads.
Expanding a grandfathered system
If your system predates 2025, it keeps retail-based credits through January 2040. LPC applies value-of-solar to systems expanded after January 1, 2025. Adding a few panels could cost more in lost credit value than they produce, so we get LPC’s answer in writing before designing an expansion.
When solar isn’t the answer
If you rent or your roof won’t work, LPC’s Renewable Power Purchase Program lets you buy renewable power without panels. From January 1, 2027, plug-in solar up to 1,920 watts will be allowed with a notification — useful for trimming daytime use, but it earns no bill credit.

How exports are credited
Exports credited at a value-of-solar rate below retail
System size limit
Confirmed per project
Net metering, in plain English
For systems installed or expanded after January 1, 2025, exports earn a value-of-solar bill credit, which is below the retail rate. Systems installed before then keep retail-based credits through January 2040. Self-generation customers pay a higher fixed monthly customer charge and a lower energy charge.

FAQ
Questions we hear
Does Longmont still have net metering?
Yes, but systems installed or expanded after January 1, 2025 are credited for exports at a value-of-solar rate below retail. Older systems keep retail-based credits through January 2040.
What is Longmont’s value-of-solar rate?
LPC publishes it on its residential and commercial rate pages. We use the current published rate in every proposal rather than an estimate.
Does LPC offer a solar rebate?
Not as of September 2026. LPC points customers to Efficiency Works for efficiency rebates.
Will adding panels to my old Longmont system change my credits?
It can. LPC applies value-of-solar to customers who expand systems after January 1, 2025. Confirm with LPC before expanding.
