Helping Riverside County homeowners navigate SCE rates and solar options since 2020
If your SCE bill is over $200 a month and climbing, you are not alone. Rates in Southern California have increased more than 80% over the past decade and the trajectory is not changing. The question most homeowners ask at this point is straightforward: what would solar actually cost, and would it be worth it?
This article gives you real numbers - not marketing estimates. System sizes, monthly PPA payments, net savings from day one, and what the tax credit does if you decide to buy. All based on current SCE rates and 2026 installation costs in Riverside County.
1. The $200 Bill Problem
SCE's average residential rate is 34.5¢/kWh in 2026 - up 83% from ten years ago. When you break down what a given bill actually represents in electricity consumption, the numbers are striking:
These are real numbers Temecula-area homeowners face every month. And because SCE has received CPUC approval to increase rates further through 2028, the bill you have today is not the bill you will have in two years.
SCE rates have increased at roughly 7% per year on average. A $300/month bill today becomes a $421/month bill in five years at that pace. Solar locks in a lower rate and insulates you from that trajectory.
2. What System Size Do You Actually Need?
System size is driven by your consumption - how many kilowatt-hours per month you actually use. Here is a straightforward mapping from bill amount to system size for Riverside County homes (based on 5.5 peak sun hours/day average):
These are estimates based on average usage patterns. Your specific system size will depend on actual consumption data from your SCE account, roof orientation, shading, and whether you plan to add an EV or other large loads in the next few years.
3. The PPA Option: No Money Down
With a $0-down solar PPA, you pay nothing to install. The solar company owns the panels, handles all maintenance, and you simply pay for the electricity they produce - at a rate currently 36% below SCE's.
- PPA rate: 22¢/kWh (locked in at contract signing)
- SCE rate: 34.5¢/kWh (currently, and rising)
- Savings per kWh: 12.5¢ - 36% less than SCE
What that looks like in real monthly dollars:
The PPA does include a 3.5% annual escalator - your rate increases each year. But SCE has increased at 7% per year historically. The gap between your PPA rate and what you would have paid SCE grows every year in your favor.
4. What About Rate Increases?
The PPA escalator (3.5%/year) sounds like a concern until you compare it to SCE's actual trajectory. Here is how the rates diverge over time starting from 2026:
By year 10, your PPA rate is still less than half what SCE will charge. The savings do not shrink over time - they grow. This is why a 25-year PPA is not a risk; it is a hedge against a rate structure that has consistently gone in one direction.
5. The 30% Federal Tax Credit
If you choose to buy (rather than use a PPA), the Section 48E federal tax credit covers 30% of the total installed system cost. Here is what that means for a typical system:
- Installed cost (before credit):~$18,000
- 30% federal tax credit:-$5,400
- Your net cost:~$12,600
On a 20-year solar loan at 5.99% APR, a $12,600 net cost comes to roughly $90/month. For a homeowner currently paying $300/month to SCE, that is still $210/month in savings - every month, for 20 years.
The Section 48E safe harbor deadline is July 4, 2026. After that date, this 30% credit is no longer guaranteed. If you are considering buying (not a PPA), act before July 4. Read the full breakdown in our federal tax credit deadline article.

Frequently Asked Questions
SCE received CPUC approval for a 12.9% rate increase effective January 2026, on top of earlier increases. Combined with the 2024 and 2025 hikes, the average Riverside County household is paying approximately 30% more than two years ago. Homes with A/C running through Inland Empire summers are hit hardest - SCE peak rates reach 58 cents per kWh during afternoon and evening hours.
A system sized to offset a $400/month SCE bill typically reduces grid draws by 70-90%, bringing the bill to $40-80/month depending on system size and battery storage. With a $0 down PPA, the combined solar payment plus residual SCE bill typically runs $180-240/month - still significantly less than $400.
SCE no longer offers direct solar rebates. The main financial mechanism is NEM 3.0 net billing, which credits exported solar at avoided-cost rates (roughly 5-8 cents/kWh). Homeowners who purchase a system can claim the federal 30% Investment Tax Credit. California's SGIP program provides rebates for battery storage systems added alongside solar.
For a purchased system, payback is typically 7-9 years for Temecula homeowners with $300-500/month SCE bills, after which electricity costs near zero for the remaining 15+ years of system life. With a $0 down PPA, there is no payback period - savings start month one with no upfront investment.
With a PPA, the solar company owns the panels and you pay per kWh at a rate below SCE. You pay $0 to install and $0 for maintenance. Buying means you own the system, pay upfront (or finance it), and the electricity it produces costs you nothing. PPA = no risk, lower total return. Buying = upfront cost, higher total return.
