Helping Riverside County homeowners navigate SCE rates and solar options since 2020
Most solar problems happen before the first panel goes on the roof. Customers skip pre-purchase due diligence, accept quotes without comparing price per watt, and sign contracts without reading escalator clauses or dealer fee disclosures. By the time the install is done, the leverage is gone.
This checklist covers every decision point in chronological order. It is built for California homeowners, specifically those in SW Riverside County (Temecula, Murrieta, Menifee, Lake Elsinore, Wildomar) where SCE service territory and local HOA rules create specific considerations.
1. Pre-Purchase Checklist
Run these checks before requesting a single quote. Issues found here could change the size of system you need, the cost to install, or whether solar makes sense at all right now.
Roof Condition
Roof age: panels typically carry a 25-year production warranty. If your roof is 12+ years old, get a roofing inspection before signing a solar contract. Re-roofing under a solar array costs 30-40% more than a standard re-roof because panels must be removed and reinstalled.
Roof material: asphalt shingle, concrete tile, and metal standing seam are all compatible with standard mounting hardware. Spanish clay tile, wood shake, and flat tar and gravel roofs add complexity and cost. Ask any installer for a specific mounting plan if you have non-standard roofing.
Structural capacity: most California residential roofs are engineered for standard dead and live loads. A 400W panel weighs approximately 45 lbs. A 20-panel system adds 900 lbs distributed across roof framing. Ask your installer for a structural assessment if the home is pre-1980.
Condition assessment: soft spots, visible sagging, or active leaks must be repaired before installation. Most reputable installers will identify these during site survey. Confirm they have done a physical walk, not just a satellite estimate.
Shade Analysis
Use a tool like Sunmetrix, Google Project Sunroof, or ask the installer to provide a shading report for your specific roof plane. A south-facing plane with 10% shade from a neighbor's tree can reduce production by up to 30% if your system is not designed with optimizers or microinverters.
Note any planned changes: a new tree, a planned addition, or a neighbor who mentions adding a second story. Future shade is not captured in any model and is your responsibility to disclose.
Temecula and Murrieta homes with Western orientation can still work well. West-facing arrays underperform south by 12-15% on annual production but produce well during peak TOU pricing hours (4-9pm), which improves bill savings under NEM 3.0.
Electrical Panel Capacity
Verify your main panel is 200A or has room to add a solar disconnect. Panels under 100A or older Federal Pacific or Zinsco panels may need replacement before solar can be permitted. Panel upgrades typically cost $1,800-3,500 in Riverside County.
If you are adding an EV charger at the same time as solar, confirm the panel can handle both loads. A 48A Level 2 charger plus solar inverter plus existing loads on a 150A panel often triggers an upgrade requirement.
Ask your installer to pull a permit before starting any work. All solar installations in California require a permit. An installer who proposes unpermitted work is a deal-breaker, not a cost savings.
HOA Rules
California Civil Code 714 prohibits HOAs from effectively banning solar panels, but they can require approval for aesthetics. Submit your HOA application before signing a solar contract so you understand any design restrictions.
HOAs can require panels to be not visible from street level, match roof color within reason, or avoid certain roof planes. These restrictions can affect system size and orientation, which affects production estimates.
Most HOAs in Temecula and Murrieta approve solar within 45 days of application. If an installer is not familiar with the HOA approval process in your community, that is a concern.
Ownership vs. Renting
You must own the property to sign a solar purchase agreement or loan. Renters cannot install solar on a property they do not own. Community solar programs exist but are limited in SCE territory.
If you plan to sell within 5 years, understand how your solar agreement transfers. Owned systems add to appraised value and transfer with the property. PPAs and leases require the buyer to assume the agreement or require you to buy out the contract at sale.
If you are buying a home with an existing PPA or lease, request the full agreement before closing. Know what the buyout cost is, what the monthly payment is, and when the agreement expires.
2. During the Quote Process
Get at least three quotes before deciding. Use price per watt as the primary comparison metric, not total system cost. A larger system at a lower cost per watt may still be a better value than a smaller system at higher cost per watt if production is adequate.
Questions to Ask Every Installer
What is the system size in kilowatts DC and what is the annual production estimate in kilowatt-hours? (These numbers let you calculate price per watt and cost per kWh offset independently.)
What panel brand and model are you quoting? Get the spec sheet. Look for degradation rate (good panels degrade less than 0.5% per year), efficiency (20%+ for premium panels), and temperature coefficient (lower is better for hot inland climates like Temecula).
What inverter technology are you using and why? String inverters are lowest cost but produce at the rate of the weakest panel. Microinverters and DC optimizers cost more and perform better when shade is a factor.
What warranties does this system carry? Ask for workmanship warranty, panel product warranty, panel performance/production warranty, and inverter warranty - separately. These are four distinct documents.
Who files the permit and who handles the SCE interconnection application? Confirm these are included in the price. Some installers charge separately for permit fees.
What is your CSLB license number and what is the expiration date? You can verify California Contractors State License Board status at cslb.ca.gov. A valid C-10 (electrical) or C-46 (solar) license is required.
Price Per Watt Benchmarks for SW Riverside County
In 2026, the fair market range for a purchased solar system in Temecula, Murrieta, Menifee, and surrounding communities is $2.30 to $2.60 per watt DC before the 30% federal Investment Tax Credit. This range reflects quotes from installers operating in this specific market.
Installer Red Flags
Cannot provide a CSLB license number on the spot, or the license is expired when you verify it online.
Provides only a total system price and cannot break down cost per watt.
Claims you will have a zero dollar electricity bill every month. Under NEM 3.0, every SCE customer pays a minimum baseline delivery charge even with solar.
Offers same-day signing incentives or tells you the price expires tomorrow.
Does not mention the NEM 3.0 interconnection requirement or does not explain how export credits work under current policy.
Proposes installing without a permit because it will speed up the process.
3. Contract Checklist
Read the contract before signing. This is not optional. A California solar contract is typically 30-60 pages. The provisions below are where mistakes happen most often.
Escalator Clauses
A PPA or lease agreement typically includes an annual payment escalator of 0% to 3%. At 2% escalation, your year-1 PPA rate of 22 cents becomes 26.8 cents in year 10 and 32.7 cents in year 20. Model out the full 20-25 year payment schedule before signing.
If the escalator is tied to an index (such as the Consumer Price Index), ask for the historical average of that index and model a range of scenarios.
Some purchase agreements include escalator clauses on monitoring fees or service plans. Read the fine print on any recurring charge, not just the main system payment.
Dealer Fee Disclosure
California law requires solar installers to disclose dealer fees charged by their financing partners. These fees are typically 20-30% of the financed amount and are paid by the installer to the lender upfront, then baked into your loan principal.
Example: an $18,000 cash-equivalent system with a 25% dealer fee means the lender actually advanced $22,500 to the installer. Your loan is for $22,500, not $18,000. You pay interest on the full $22,500.
Ask for the dealer fee percentage in writing before signing. If an installer refuses to disclose it or claims there is no dealer fee on a financed transaction, that is incorrect - all solar lending products in California include some form of dealer/origination fee.
Production Guarantees
A production guarantee commits the installer to a minimum annual kWh output. If the system underperforms, they compensate you for the difference at your contracted rate. Not all installers offer production guarantees - ask specifically.
Verify the guarantee covers the specific production number cited in your proposal, not an estimate range. Some proposals show a range of 9,800-11,200 kWh per year; the guarantee may only cover the lower bound.
Understand what triggers the guarantee: typically, it applies only when underperformance is caused by equipment failure or installation error, not shade growth, weather deviation, or your usage habits.
Warranty Terms
Covers installation quality: roof penetrations, wiring, mounting hardware. Standard is 10 years minimum. Ask who backs this warranty - the installer, and what happens if the installer goes out of business.
Covers manufacturing defects and physical panel failure. Industry standard is 25 years from Tier 1 manufacturers (Jinko, LONGi, REC, Panasonic, Q Cells). Verify the warranty is backed by the manufacturer directly, not just the installer.
Guarantees minimum power output over time. Standard is 90% at year 10, 80% at year 25. Verify the degradation curve in writing. Some budget panels offer 80% at year 25 with a steeper degradation curve in years 1-10.
4. Financing Checklist
Solar financing is one of the most misunderstood parts of the buying process. These are the specific items to verify in writing before signing any financing agreement.
Loan APR: the true annual percentage rate after all fees. A 2.99% promotional rate that jumps to 6.99% after year 1 is not a 2.99% loan. Ask for the effective APR over the full loan term.
Loan term: solar loans in California typically run 10, 15, or 25 years. At the same APR, a 25-year term means far more total interest paid than a 15-year term. Get the total interest paid number for each term option.
Prepayment penalties: most solar loans have no prepayment penalty, but verify in writing. If you refinance your home, you may want to pay off the solar loan. A prepayment penalty turns that into a cost.
Dealer fee in loan principal: ask specifically what dollar amount represents the dealer fee in your loan. If the lender says the loan is for $24,000 but the cash price is $18,000, $6,000 is the dealer fee baked in. You are financing an origination cost. Know this before signing.
ITC timing: the 30% federal Investment Tax Credit is claimed when you file taxes the year the system is installed. If your installer tells you to take an ITC distribution from your loan principal within 18 months, ask how that calculation works. Missing the ITC recapture window on a loan can result in your payment jumping significantly.
Lender identity: know who your lender is. Solar-specific lenders (Mosaic, Sunlight Financial, GreenSky, Service Finance) have different terms and customer service histories. Research the lender separately from the installer.

The work is not done when the panels go up. These steps must happen before your system can legally produce and export energy to the grid.
Permission to Operate (PTO) Application
SCE must issue Permission to Operate before your system can legally turn on. This process typically takes 5-30 business days in Riverside County depending on current SCE queue. Your installer should file the PTO application and provide you the application confirmation number.
Do not turn on your system before receiving PTO. Running a solar system before SCE approval can result in fines and required disconnection.
Once PTO is received, SCE will send an email with your new bi-directional meter installation date or confirm your existing meter is compatible. Verify this step happens.
NEM 3.0 Enrollment
All new solar installations in SCE territory after April 2023 enroll in NEM 3.0 (Successor Tariff). Under NEM 3.0, excess solar energy exported to the grid is compensated at an avoided cost rate of approximately 8 cents per kWh rather than the retail rate of 34.5 cents. This is a significant change from NEM 2.0.
The practical implication: self-consumption is more valuable than export under NEM 3.0. Systems paired with battery storage that shift solar production into peak consumption hours (4-9pm) perform materially better under NEM 3.0 than solar-only systems.
Confirm with your installer that NEM 3.0 enrollment is handled as part of the interconnection application. Enrollment is automatic for new systems but verify you receive SCE confirmation.
Monitoring Setup
Every modern solar system includes a monitoring app (Enphase Enlighten, SolarEdge mySolarEdge, Solar Analytics for other systems). Set up your monitoring account on install day, not weeks later. Monitoring lets you catch production problems within days rather than after a full billing cycle.
Set up daily production alerts so you receive a notification if your system produces zero or near-zero kWh on a clear day. This is the fastest early warning for an inverter fault or disconnected panel.
Download your production data monthly and compare against the production estimate in your proposal. Track variance from the first full month. A system producing 15% below estimate in its first summer is a warranty claim, not normal variation.
Utility Program Enrollment
California SGIP rebate: the Self-Generation Incentive Program provides rebates for battery storage systems. Verify with your installer whether your battery qualifies and whether the SGIP application was filed. Waitlists are active; file as early as possible.
SCE TOU rate plan selection: under NEM 3.0, you must be on a TOU rate plan. The default plan assigned by SCE may not be optimal for your usage pattern. Request a rate analysis from SCE or a solar advisor after 90 days of solar production data.
Homeowner insurance update: notify your home insurance provider that a solar system has been installed. Most insurers cover rooftop solar under standard dwelling coverage, but coverage limits may need adjustment for systems valued at $15,000-30,000.
6. Final Red Flags List
If any of the following occur at any stage of the process, stop and investigate before proceeding.
Installer cannot or will not provide a CSLB license number for verification.
Quote is a single total price with no breakdown by component (panels, inverters, mounting, labor, permits).
Production estimate is not tied to a specific simulation tool output (PVWatts, Aurora, Helioscope). Ask for the report.
Dealer fee is not disclosed in writing before you sign.
Contract references a different system size, panel model, or inverter brand than what was discussed verbally.
Installer promises to handle your taxes or guarantees you will receive the federal ITC. They cannot make that promise. Consult your tax advisor.
Company cannot provide three local references from installs completed in the past 12 months within 20 miles of your home.
Monitoring access is not included in the contract or requires a separate monthly fee beyond year 1.
Contract does not specify who files the PTO application with SCE and how long the installer commits to supporting that process.
No 3-day right of rescission disclosure in the contract. California law requires this for consumer contracts signed at home.

Frequently Asked Questions
The fair market range for a purchased solar system in SW Riverside County in 2026 is $2.30 to $2.60 per watt DC before the 30% federal Investment Tax Credit. Quotes below $2.20 per watt warrant careful scrutiny of panel quality and warranty terms. Quotes above $2.90 per watt require clear justification - usually premium panels or battery storage inclusion.
A workmanship warranty covers installation quality issues - roof penetrations, wiring, mounting hardware - and is typically backed by your installer for 10 years. A performance warranty covers panel power output over time and is backed by the panel manufacturer for 25 years (typically guaranteeing 80% of rated output at year 25). These are separate documents from separate companies. Both should be provided in writing before you sign.
NEM 3.0 is California's current net energy metering policy for new solar installations. Under NEM 3.0, excess solar energy exported to the SCE grid is compensated at approximately 8 cents per kWh (avoided cost rate) rather than the retail rate of 34.5 cents. This makes self-consumption far more valuable than export, which shifts the economics toward solar systems paired with battery storage that can hold energy for use during evening peak hours (4-9pm) instead of exporting it.
A dealer fee is an origination charge paid by the installer to a solar lender, typically 20-30% of the financed amount. The fee is baked into your loan principal, meaning you finance and pay interest on this origination cost over the life of the loan. California requires dealer fee disclosure in the solar contract. A $18,000 cash system with a 25% dealer fee becomes a $22,500 loan. You should know this number before signing.
In Riverside County, SCE's PTO process typically takes 5-30 business days from submission. During high-volume periods (spring and summer solar season), processing can run toward the longer end of that range. Your installer files the application; ask for the confirmation number so you can track it. Do not turn on your system before SCE issues PTO approval - this is a regulatory requirement, not a suggestion.
