Solar Panel Cost in Elk Grove, CA (2026): $4.14/W State Median
By Chad SimpsonUpdated 7 sources citedElk Grove, Sacramento County
Homeowners across PG&E, SCE and SDG&E territory who bought their own solar systems reported a median of $4.14 per watt between January 2025 and May 2026, across 58,628 systems. The middle half paid $2.90 to $5.53 per watt.
Sacramento Municipal Utility District (SMUD), Elk Grove's main utility, is not in the CPUC's interconnection data, which covers only PG&E, SCE and SDG&E. The data holds no Sacramento County figure either, so the figure above is statewide.
A 6.15 kW system, the median size connected across PG&E, SCE and SDG&E territory in 2025, comes to about $25,500 at that median, or $17,800 to $34,000 across the middle half.
Those are reported costs, not a quote, and no federal credit comes off a Elk Grove system finished in 2026: 26 U.S.C. §25D does not cover one whose installation is completed after December 31, 2025 (state and federal rules).

What a solar permit costs in Elk Grove
Elk Grove does not publish a dollar figure for a residential solar permit. Whatever it charges, Government Code §66015 limits a city to $450 for a home system up to 15 kW, plus $15 per kW above that, unless it adopts a written finding that its cost is higher.
- What Elk Grove publishes: Elk Grove's Building Safety, Inspection and Permits page does not publish a solar permit fee, so ask the Building Division or the installer for the City's figure before comparing quotes. If the job goes through SolarAPP+, SolarAPP+ charges its own processing fee.
- How to file: Yes. Elk Grove's Building Division requires electronic submittals for permit applications and related documents. Its page does not describe a solar-specific route; the California Energy Commission's SB 379 data, which each city reports itself, lists Elk Grove's platform as SolarAPP+.
- Automated permit platform: SolarAPP+. Per the CEC SB 379 data (self-reported); the City page checked does not describe a solar route.
Sources: City of Elk Grove, Building Safety, Inspection and Permits, checked September 23, 2026; California Energy Commission, Residential Solar Permitting Program data (SB 379 platform status as self-reported by each jurisdiction; data last updated August 3, 2026), checked September 23, 2026; Gov. Code §66015, checked September 24, 2026. Elk Grove in the California Solar Cost Index sets this fee beside every other city's.
Solar data for Elk Grove: SMUD is not covered
SMUD customers are not in the CPUC data, so nothing in it describes most Elk Grove homes.
Across California homes served by PG&E, SCE or SDG&E, 45% of 2025 systems were leased or on a PPA, 55% had a battery and the median size was 6.15 kW.

The Elk Grove project checks that change the decision
Elk Grove is SMUD territory, not PG&E, so a savings estimate built on PG&E rates or PG&E's Solar Billing Plan does not describe an Elk Grove bill. SMUD pays a flat rate for exported power.
Ask the same three questions
- Does the savings estimate use SMUD's Solar and Storage Rate, 9.6 cents per exported kWh, and SMUD's Time-of-Day (5-8 p.m.) rate?
- Does the quote include SMUD's one-time fee to connect a new solar system?
- What City permit fee is in the quote? Elk Grove does not publish it.
Local checks
SMUD, not PG&E
The California Energy Commission's service-territory map places all of Elk Grove in SMUD's territory. SMUD is a publicly owned utility with its own solar rate, described below.
A flat export rate
A home approved to install solar on or after March 1, 2022 is on the Solar and Storage Rate, which pays 9.6 cents per kWh for exports at any hour or season since June 1, 2026. Credits carry over to later bills.
Electronic submittals
Elk Grove's Building Division requires permit applications and documents to be submitted electronically. The CEC's SB 379 data, self-reported, lists the City's automated platform as SolarAPP+.

Before you sign
In California the middle half of reported costs spans $2.90 to $5.53 per watt, and roof, panel work, equipment and contract terms explain most of that gap. California Solar Tax and Permit Rules for 2026 covers them, and the tax, lease and disclosure rules a Elk Grove contract follows.

How does SMUD pay for solar exports in Elk Grove?
Elk Grove is SMUD territory, not PG&E, so PG&E's Solar Billing Plan does not apply. A home approved to install solar on or after March 1, 2022 goes on SMUD's Solar and Storage Rate, which since June 1, 2026 pays 9.6 cents per kWh for exported power regardless of time of day or season. The customer stays on SMUD's Time-of-Day (5-8 p.m.) rate, credits carry over to later bills, and SMUD charges a one-time fee to connect a new system.
