Why You Should Get a Solar Inspection Before You Sell Your Sonoma County Home
If you’re selling a home in Sonoma County and it has solar panels, congratulations—you’re already ahead of the curve. Solar systems are a major selling point for buyers who care about energy efficiency and long-term savings.
But before you list your home, there’s one step most sellers overlook: getting a solar inspection. A solar inspection eliminates buyer confusion and gives them the confidence to submit an offer with less inspection terms. The solar inspection will:
1. Verify the System Is Working Properly
A solar inspection ensures your system is producing power as it should. Over time, panels can degrade (usually 1–2% per year), and problems like unsealed bolts, broken panels, or inverter issues can reduce output—and buyer confidence.
Fun fact: nearly 30% of solar companies fail within their first three years. That means many systems were installed by companies that no longer exist, leaving homeowners unsure who to call for service.
2. Ensure the Installation Meets Standards
Inspectors check whether panels were installed correctly and safely. City inspectors rarely climb onto roofs, so it’s common to find unbolted panels, exposed wiring, or missing sealants that could cause leaks or safety issues.
3. Smooth the Transfer for Buyers
If your solar system is leased or under a Power Purchase Agreement (PPA), buyers will want to understand the details. A solar inspection will:
-
Confirm the lease terms match the actual system installed.
-
Review third-party contracts for fair terms (ideally under 30 years and below the current kilowatt rate).
-
Verify there’s a production guarantee (best case is a monthly production guarantee, with an annual “true-up” under $300).
Having this information ready helps you transfer ownership smoothly and keeps negotiations clean.
4. Answer Buyer Questions Before They Ask
Buyers will want to know:
-
How big is the system?
-
How much does it save annually?
-
Is it sized properly for their energy use?
-
How do they monitor production or request service?
A solar inspection provides the answers and gives buyers confidence in the system’s value.
5. Keep the System Performing at Its Best
Dust, pollen, and even bird nests can create shade that clogs up energy flow (think “electron bottleneck”). An annual cleaning is recommended to keep your panels efficient and extend their lifespan.
Inspectors can also check for critter damage (yes, squirrels love to chew solar wires) and recommend adding a wire guard if needed.
6. Understand Your NEM Tier Before Making Changes
If you’re on NEM 1, congratulations—it’s the most generous net metering program. Don’t make system changes that bump you to NEM 2 or NEM 3, where credits are lower and rates fluctuate by time of use.
7. Battery or No Battery?
Some homeowners add batteries for backup power or to offset peak rates. Just know that not all systems are configured for both economic and backup use. A solar inspection can help determine if adding a battery makes sense.
8. Get a Professional Solar Report
Companies like Shine On Solar offer a comprehensive inspection for about $299, which includes:
-
System performance testing
-
Repair estimates
-
Power output review
-
Contract guidance for third-party systems
They also offer cleaning and diagnostics services. In many cases, fixing an inverter ($4K–$5K) or replacing a damaged panel ($550) pays for itself for a smoother sale and a stronger home value presentation.
