Wildomar incorporated as a city in 2008 and has grown steadily as residential overflow from Murrieta and Temecula pushed development north along the I-15 corridor. The city sits entirely within Southern California Edison territory, and as of 2026, residential customers pay 34.5 cents per kilowatt-hour on Tier 1 usage and 41 to 43 cents on Tier 2. The CPUC has approved rate increases through 2028, meaning the trajectory is set for at least two more years of increases on top of the current rate.
Wildomar's housing stock is a mix of 2000s-era construction and newer builds, with a growing school-age population that suggests a high proportion of family households with corresponding electricity loads. This article covers what Wildomar homeowners currently pay, why the solar math works here, and what a $0-down PPA looks like in practice. For the full context on the rate increase schedule, read the SCE rate increases 2026-2028 breakdown.
1. What Wildomar Homeowners Pay SCE
Wildomar's homes range from smaller older properties to 2,000 to 3,000 square foot family homes in subdivisions built from 2000 to 2015. Monthly electricity consumption correlates closely with home size and household size.
Typical Wildomar SCE Bills (2026)
Summer months push bills significantly higher. Wildomar's location in the Elsinore Valley means temperatures regularly exceed 100 degrees from June through September. Central air conditioning running during peak heat can add $100 to $200 per month above the winter baseline for a typical family home.
2. Wildomar Housing Stock and Solar Fit
Most of Wildomar's residential development occurred in three distinct waves: older homes built before the city incorporated, homes from the late 1990s to early 2000s built in early Wildomar subdivisions, and newer builds from roughly 2005 to 2015 when the city experienced its primary growth phase.
Homes from the 2000 to 2015 window sit in a favorable position for solar in 2026:
Adequate roof life remaining
A home built in 2005 has a roof that is approximately 20 years old. Most composition shingle roofs carry a 25 to 30 year lifespan, so there is typically 5 to 10 years of remaining life. This is sufficient to install solar without an immediate re-roof concern. Homes built after 2010 have 15+ years of remaining roof life with no timing concern.
Modern electrical infrastructure
Homes built after 2000 have 200-amp panels as standard. This is the electrical requirement for a typical residential solar installation. No panel upgrade is typically needed, which keeps the installation straightforward.
Good sun exposure
Wildomar's location in southwest Riverside County gives it the same high sun exposure as Temecula and Murrieta, with roughly 275 to 290 sunny days per year. This translates to strong solar production and good financial returns on any installed system.
3. Growing Families and Electricity Load
Wildomar has seen consistent growth in its school-age population, which is a proxy for family household growth. Families with children use more electricity than smaller households: more laundry, more cooking, more devices charging simultaneously, more time at home. A household that was using 900 kWh per month in 2020 may be using 1,100 to 1,200 kWh per month in 2026 as the family has grown.
This matters for solar sizing. When you get a solar proposal, the system is sized based on your current usage. If your usage is growing because your family is growing, it is worth accounting for that trajectory when discussing system size. A system sized for today's 1,000 kWh per month may only partially offset a 1,400 kWh per month household five years from now.
The practical guidance: during the proposal process, share your usage history if it has been trending upward. A good installer will note this and may recommend a slightly larger system to account for reasonable growth. Under a PPA, you only pay for what the panels produce, so a larger system does not increase your risk if your usage happens not to grow as projected.
4. The $0-Down Solar PPA
A Power Purchase Agreement remains the most accessible entry point for Wildomar homeowners who want to reduce their SCE bill without a large upfront investment. The key terms:
5. Monthly Savings Breakdown
For a Wildomar family home using 1,000 kWh per month at current SCE rates:
Year 1 Monthly Comparison (1,000 kWh/mo)
Year-one savings are meaningful but not dramatic. The full financial case for solar is built on the 25-year trajectory, where the rate differential between a locked PPA escalator and SCE's uncapped rate compounds significantly over time.
6. How Savings Grow Over Time
A 25-year projection for a Wildomar home at 1,000 kWh per month:
Projections assume SCE 7% annual increase and PPA 3.5% annual escalator. Your personalized proposal will reflect your contracted rate and actual system design.
7. Locking In Your Rate Before 2028 Increases
The CPUC has authorized SCE rate increases for 2026, 2027, and 2028. These are not hypothetical. They are filed, approved, and scheduled. The rate you sign a PPA at today reflects current SCE pricing. A PPA signed in 2027 will be priced against a higher SCE baseline, meaning the starting rate and the savings projection will both shift.
This is not a sales pressure argument. It is a rate mechanics observation. If your PPA starting rate is set relative to current SCE pricing, and SCE raises rates further before you sign, your PPA starting rate will likely be higher in absolute terms. The savings percentage stays roughly the same, but the dollar amount changes.
For Wildomar homeowners who are considering solar in the 2026 to 2027 window, getting a proposal now lets you see current rate projections before the next round of CPUC increases takes effect. There is no obligation in getting a proposal.
8. Getting Your Estimate
Your monthly SCE bill is the primary input for a savings estimate. Everything else follows from that number: system size, production estimate, PPA rate, and total savings over 25 years.
