Is the Equipment in My Solar Quote CEC-Listed? How to Verify Model Numbers
The California Energy Commission's Solar Equipment Lists include panels, inverters, batteries and related equipment that meet national safety and performance standards, and they're updated three times a month. Incentive programs use them, and some utilities and local governments use them when they review interconnection and permit applications — though the CEC is clear that being listed isn't itself required to install equipment in California. For a homeowner, the lists are a quick way to confirm that the exact model in a quote is a real, tested product with published ratings. The check takes a few minutes: get the full model number from the quote or datasheet, find it on the list — or on its page in Cali-Graf, the free equipment directory built by Cali Energy, a Los Angeles solar and roofing contractor, which shows the listing and its date — and ask the seller about anything that doesn't match.
Step 1 — Get the exact model number
A quote should name each piece of equipment by manufacturer and model, not just a brand or a wattage. Model numbers often carry suffixes that matter — a power class, a black frame, a voltage, an output rating — so copy them exactly. "Premium 430 W panels" or "or equivalent" isn't a model number; ask for one.
Step 2 — Look it up
| Where | What you get |
|---|---|
| The CEC's Solar Equipment Lists | The official lists — PV modules, inverters (including smart inverters), batteries and energy storage systems — viewable or downloadable |
| Cali-Graf's equipment page for the series | CEC listed with the date, every model in the series as listed, specs with sources, warranty, tests and local installs |
On a Cali-Graf page, the models table shows each listed variant. For batteries and inverters, the listing is often per output rating or voltage — Tesla's Powerwall 3, for example, has five listed configurations from 5 to 11.5 kW. A note on the page flags listing quirks, such as a manufacturer that was formerly listed under another name.
Step 3 — Read what the listing says
- Ratings. Power for panels; continuous power and energy for batteries; weighted efficiency for inverters — measured to the standards the list requires.
- Listing date. When the model was added.
- Grid functions. For inverters and batteries, whether the equipment carries UL 1741 SB, the grid-support certification used for California's interconnection rules.
- Code notes. For batteries, notes such as a JA12 declaration for California's energy code for new homes, and any limits the CEC records.
What each spec means in plain terms is in how to read a solar panel spec sheet and how to read home battery specs.
If the model isn't there
| What you find | What to ask |
|---|---|
| The brand is listed, but not this model | "Is the model number in the quote exact? Which listed model is it?" |
| A different power class or rating than quoted | "Why does the quote say 430 W if the listed model is 410 W?" |
| Not listed at all | "Why this product, and will my utility, permit office or any incentive accept it?" |
| A newer model not yet listed | "When is it expected on the list?" |
An unlisted product isn't automatically unsafe or illegal, but it's a reason to slow down — especially if you're counting on an incentive that requires listed equipment. In Cali-Graf's design tool, a panel that isn't on the list is marked not in the CEC list — only the datasheet values are known.
Two more checks while you're there
- Who installs it locally. Each Cali-Graf equipment page lists the licensed installers whose Southern California permits name the product; see what equipment does my installer actually install?.
- Independent tests. Where published, Kiwa PVEL and RETC results appear on the page; see PVEL and RETC results explained.
