Helping Riverside County homeowners navigate SCE rates and solar options since 2020
Solar pricing is one of the most commonly researched and least clearly answered questions in home improvement. You will find ranges like "$15,000 to $50,000" plastered across the web - technically accurate, completely unhelpful. This article gives you the actual numbers for Wildomar homes, broken down by system size, financing method, and what drives price variation here.
Wildomar is an unincorporated area that became a city in 2008, nestled between Murrieta and Lake Elsinore. From a solar perspective, Wildomar and Murrieta are nearly identical - same solar resources, same SCE utility territory, and the same installer market serving both cities. The main practical difference is that permits run through Wildomar City rather than Murrieta, and the Wildomar permit office averages 3-4 weeks turnaround vs 2-3 weeks in Murrieta.
Upfront: there are two fundamentally different ways to get solar - buy the system or use a PPA. The price question looks very different depending on which route you take. We cover both.
1. The Short Answer
The rest of this article explains what drives the numbers in each scenario and how to figure out which one applies to your specific home and usage.
2. Cost by System Size
System cost scales with size, which is determined by how much electricity your home uses. Here are the real 2026 installed costs for the Wildomar and Southwest Riverside County market:
3. Why Prices Vary
Within any system size category, final price varies based on several factors. Understanding them helps you evaluate quotes accurately:
When comparing quotes, look at cost-per-watt rather than total price. A 6.5 kW system at $3.00/watt is $19,500. The same spec at $2.38/watt is $15,470. Cost-per-watt strips out size differences and lets you compare apples to apples.
4. The $0-Down PPA: A Different Calculation
A PPA removes the purchase price question entirely. Instead of buying a system, a solar company installs panels on your roof at no cost and you pay for the electricity they produce.
For most Wildomar homeowners with a $200-$400/month SCE bill, the PPA monthly payment is significantly lower than the current SCE bill - meaning you start saving from the first month without spending a dollar. For a side-by-side cost breakdown, see the full PPA vs purchase breakdown.
5. Solar Loan Option
If you want to own without paying cash upfront, a solar loan is a middle path. Here is how the numbers work for a typical Wildomar home:
- Installed cost:$19,500
- Federal tax credit (30%):-$5,850
- Net cost after credit:$13,650
- 20-year loan at 5.99% APR:~$97/month
- Monthly savings vs $240 SCE bill:~$143/month
After the tax credit reduces the financed amount, the monthly loan payment can be well below what you were paying SCE - making a solar loan a compelling option even for homeowners who do not have cash on hand.
One important note: the 30% tax credit safe harbor deadline is July 4, 2026. If you are considering a loan purchase to own the system and claim the credit, starting the process now means you are not rushed.
6. Wildomar vs Murrieta vs Temecula: Does Location Matter?
For solar production: essentially no. Wildomar, Murrieta, and Temecula all sit in the same inland valley with nearly identical solar resources. All three are SCE territory. Here is how they compare:
All three cities have nearly identical sun resources and pricing. The only practical difference between Wildomar and Murrieta is the permit timeline - Murrieta runs 2-3 weeks while Wildomar averages 3-4 weeks. Neither difference materially changes the economics of going solar.
System pricing for the same specification is essentially the same across all three cities. The panel brands, inverter types, and installation labor do not change based on which side of the city limit line your house is on.
7. The Best Way to Know Your Number
The ranges above give you a framework, but your actual number depends on your specific SCE bill, roof size, and shading situation. The fastest way to get a real estimate is the free calculator on this site.
Enter your average monthly SCE bill and you get:
- Estimated system size (kW and number of panels)
- Monthly PPA payment vs your current SCE bill
- Monthly savings from day one
- 25-year total savings projection

Frequently Asked Questions
Yes - reputable installers include permit fees in their quotes. Ask specifically when comparing quotes. Some installers list permits as a separate line item; others bundle them. The total cost is what matters.
Wildomar is served by Southern California Edison (SCE). This is the same utility serving Murrieta, Temecula, and most of Southwest Riverside County. Your interconnection process, net metering rules, and bill structure are the same as neighboring cities.
Panel-level optimizers or microinverters are sometimes quoted separately from string inverter systems, so compare inverter specs. Battery storage is always a separate line item unless explicitly included. Main panel upgrades (if your electrical panel is undersized) are also separate and can add $1,500-$3,000.
In a purchase scenario (cash or loan), the typical payback period for Wildomar homes is 7-9 years, after which the electricity is effectively free for the remaining 15+ years of system life. With a PPA, there is no payback period - you start saving from month one.
SCE no longer offers direct solar rebates. However, the SGIP (Self-Generation Incentive Program) provides rebates for battery storage systems in California. If you are adding a battery alongside solar, SGIP rebates can significantly offset the battery cost. Ask about SGIP eligibility when you get your quote.
