Planning a heat pump or solar installation in Folsom? This page covers every SMUD energy rebate in one place, then matches you with a vetted local installer.
In 2026, a Folsom homeowner served by SMUD can claim $3,000–$4,000 for a heat pump, $2,000 for solar, $5,400 for a home battery, $4,000 for a heat pump water heater, and $1,600 for insulation. SMUD's My Energy Optimizer program can add up to $10,000 more for enrolling a battery in demand-response.
Folsom is served by SMUD (Folsom Municipal Utility District), a municipal utility with some of the most generous, straightforward rebates in California — no NEM 3.0 complications, and rebates that stack with the federal tax credit.

A typical household combining a heat pump and solar keeps $5,000–$6,000 in direct SMUD rebates. Add the battery storage enrollment bonus and a household pursuing the full stack can reach well over $15,000 in rebates and incentives before the federal tax credit is even applied.
Two quick questions — free, instant estimate, no sales calls.
Start your assessment →Beyond the standard $5,400 battery rebate, SMUD's My Energy Optimizer program pays homeowners to enroll a qualifying battery in demand-response — letting SMUD tap a small amount of stored power during grid stress in exchange for an enrollment bonus that can reach up to $10,000. This stacks with the base rebate and with the federal residential clean energy tax credit, and it's the single largest dollar opportunity on this page for households considering both solar and storage together.

These are the backbone. They're the same whether you're in Sacramento, Folsom, Roseville, or Rancho Cordova — SMUD serves the whole metro area under one utility, unlike much of California which is split across investor-owned utilities.
A cold-climate heat pump both heats and cools your home using electricity. Amount depends on system size and efficiency tier.

SMUD (Folsom Municipal Utility District)
Strong, reliable sun
Central Valley climate means consistent solar production most of the year — a key reason the payback here beats coastal California.
Mixed gas and electric
Hot summers mean cooling matters as much as heating — a heat pump handles both.
Municipal utility, generally reliable
SMUD is publicly owned and not subject to the same wildfire-related outage patterns as some investor-owned California utilities.
SMUD's heat pump rebate runs $3,000–$4,000 depending on system size and efficiency tier. A typical 3-4 ton system costs $13,000–$22,000 installed, so most Folsom homeowners net $9,000–$19,000 out of pocket, paying back in roughly 14 years from the $900/year in savings.
Folsom gets strong, reliable sun most of the year, which is why the payback here is faster than coastal California. A 6kW system runs $15,000–$18,000, and after the $2,000 SMUD rebate the payback is about 11 years from roughly $1,400/year in savings.
Beyond the $5,400 battery rebate, SMUD's My Energy Optimizer program pays up to $10,000 in additional incentives for enrolling a qualifying battery in demand-response, on top of the standard rebate and any federal credit you claim.
Yes. SMUD rebates are separate from and stack with the federal residential clean energy and energy-efficiency tax credits, so you claim both without either one reducing the other.
Renters can't claim the structural rebates directly since those go to the property owner, but SMUD's My Energy Optimizer program offers free or discounted efficiency devices open to renters. Condo owners can pursue in-unit upgrades like a heat pump water heater with building approval; whole-building retrofits go through the HOA. See the full breakdown below.
Apply through an SMUD-participating contractor before work begins wherever possible — some SMUD rebates require pre-approval, and starting work first can forfeit eligibility.
Most rebate dollar figures on this page assume you own the property and control the whole building. Here's what changes if you rent or live in a condo:
You can't claim the structural rebates (heat pump, insulation, solar, battery) — those go to whoever owns the property. SMUD's My Energy Optimizer program does offer free or discounted efficiency devices open to renters. If you want the bigger upgrades, the ask has to go to your landlord.
In-unit upgrades you control yourself — a heat pump water heater, an in-unit heat pump — may qualify for the rebates above with your building's approval, usually required for anything touching shared systems or exterior walls.
Heat pumps, insulation and solar for a whole condo or apartment building go through the HOA or property owner as a group decision, not the single-family numbers on this page. Contact SMUD directly to ask about multifamily program options.
