Service Overview
What Is a Solar Inspection?
A solar inspection is a comprehensive, data-driven evaluation of a home’s photovoltaic system — from panel output and inverter condition to installation quality and remaining useful life. The result is a graded, shareable certificate you can use during a home purchase, sale, or for your own peace of mind.
Add-On to a Home Inspection
Pair the solar inspection with any complete home inspection for an integrated picture of the entire property. Ideal for buyers who want everything documented in a single inspection visit — the home and the solar system together.
Stand-Alone Solar Inspection
Already own your home or representing a seller who wants to market their solar proactively? Schedule a solar inspection on its own, any time, without bundling it with another service. Perfect for homeowners, sellers, and agents preparing a listing.
What You Receive
A Sprk Solar graded certificate (A–F), a full solar system detail report covering production health, remaining system life, safety & quality, and energy storage evaluation. Sellers also receive a Solar Listing Report to support marketing.
How It Works
A Tech Inspect certified inspector visits the property, performs the on-site inspection, and collects all required system data. Sprk Solar then generates the professional graded report — typically delivered within 24–48 hours of the inspection.

Know What You're Actually Buying
When a home has solar, the listing will highlight the savings — but what it won’t tell you is whether the system is functioning, how many years of production remain, or whether the solar is actually owned by the homeowner. These details directly impact the home’s value and your monthly costs.
Solar only saves you money if two things are true: the system is functional, and it’s owned by the homeowner (not leased or under a PPA that transfers to you). Our inspection addresses both — before you close.
- Verify energy production health — measured kWh output vs. expected production
- Understand remaining system life — separate grades for panels and inverter
- Confirm the ownership model — owned, loan-financed, leased, or PPA
- Evaluate installation quality — safety, labeling, wire management, setbacks
- Assess energy storage — battery backup status and net metering confirmation
- Get a graded A–F certificate — a clear, objective score you can negotiate from

Market Your Solar. Maximize Your Value.
A solar system is one of the most valuable upgrades a home can have — but only if buyers understand and trust the value. A proactive solar inspection positions you as a transparent seller and ensures the system is accurately represented and correctly valued before negotiations begin.
We generate a Solar Listing Report — a professional, shareable document designed specifically to support your listing. It highlights energy production, annual savings, system age, ownership structure, and projected 10 and 25-year buyer savings. Your agent can attach it directly to listing sites and marketing materials.
- Get ahead of buyer inspection requests — no surprises during escrow
- Support correct home valuation — give appraisers documented system data
- Increase listing appeal — buyers love verified, quantified energy savings
- Strengthen your negotiating position — with third-party certified data
- Receive a Solar Listing Report — ready to share with agents and buyers
For Real Estate Professionals
Serve Your Clients Better on Every Solar Transaction
Solar transactions are complex. Ownership models, transfer procedures, loan assumptions, and system valuations all require specialized knowledge. Our Solar Inspection Report gives you the data your clients need — and the documentation you need to protect the transaction.
Assess Energy Production Health
Know exactly how much energy the system is producing versus what it's expected to produce. Measured kWh output, monthly production charts, and a scored health rating give you and your clients real numbers to work from.
Remaining Useful Life
Separate grades for solar panels and inverter show the remaining life in years and percentage. This directly supports appraisal value and helps buyers understand the long-term savings trajectory they're actually purchasing.
Installation Quality Evaluation
The safety and quality score evaluates breaker labeling, conduit labeling, fire code setbacks, pest proofing, wire management, and panel condition. An independent quality grade you can share with confidence.
Energy Storage & Boost Listing Appeal
Battery backup and net metering status are documented and scored. Listings with a verified solar certificate and clear savings data stand out — and buyers who understand the value are more confident and motivated to close.
Solar Transfers & Contracts: What Every Agent Needs to Know
Loan assumptions, PPA transfers, UCC-1 lien releases, escrow coordination, and utility net metering transfers all require specific steps. Our in-depth guide covers the full process for both buyers' and sellers' agents — from listing to close.

Common Questions
Frequently Asked Questions
Everything you need to know about our solar inspection service.
Why should I get a solar inspection when buying a home?
Solar panels have no moving parts — there's no obvious way to know if they're working without measurement. Many original installers have gone out of business. An inspection confirms production levels, system condition, ownership structure, and remaining life before you commit to the purchase.
Does solar add value to a home?
Solar adds value only when it's owned by the homeowner (not leased or under a PPA) and in good working condition. A solar inspection and listing report documents the system's verified value and ownership model clearly for buyers and appraisers.
How long does a solar system last?
A well-installed solar system can last 50 years or more. Panels typically retain around 80% efficiency at year 25–30. Inverters generally need replacement every 10–15 years. Our inspection shows exactly where on that life cycle your specific system sits.
What is included in the graded certificate?
The A–F graded certificate covers four scored categories: Solar System Remaining Life, Solar Energy Production, Solar Energy Storage (battery/net metering), and Safety & Quality. You also receive detailed system specs, inverter data, installer info, and projected savings.
Can I get just a solar inspection, without a full home inspection?
Yes. The solar inspection is available as a fully stand-alone service. You do not need to purchase a complete home inspection. It can also be added to any complete home inspection for an integrated property assessment.
How does the solar transfer work when selling?
The process depends on whether the solar is owned outright, financed with a loan, or leased/PPA. Each situation requires different steps involving the lender or lease company, escrow, and the utility provider. See our agent guide for a full walkthrough of each scenario.
Ready to Know What Your Solar Is Really Worth?
Whether you’re buying, selling, or just want peace of mind — a solar inspection takes the guesswork out of one of your home’s biggest assets.
