What we check

Six things we read before you sign

A solar contract is one of the larger purchases a homeowner makes — and the most important details are the ones easiest to gloss over. Here's exactly what we look at.

Price per watt ($/W)

The single cleanest way to compare two quotes for different system sizes. We translate your proposal to a $/watt figure and tell you where it lands versus a fair, installed-and-permitted price in your area.

Equipment tier

Which panel, inverter, and battery brands are actually specified? Tier-one hardware and a Tesla Powerwall 3 (13.5 kWh usable, 11.5 kW output, ~10-year warranty) are not the same as unnamed, white-label parts quietly swapped in later.

Production-estimate honesty

Does the proposal's projected production and savings account for NEM 3.0, your roof's real orientation and shading, and your actual usage — or is it an optimistic model designed to make the payback look shorter than it is?

Financing fine print

We read the part most people skip: payment escalators that raise your bill every year, dealer fees baked into a low APR, and the difference between a true cash price and a financed price. $0-down lease/PPA structures can pass the commercial §48E credit through to you — we confirm whether yours actually does.

Warranty & who stands behind it

A 25-year warranty only matters if the company is still around — and reachable — to honor it. We check who carries the workmanship, equipment, and production guarantees, and whether service is handled locally or routed to a call center three states away.

Who actually does the work

Many quotes come from sales-only dealers who subcontract the install to whoever is cheapest that week. We confirm the licensed installer of record so you know exactly who is on your roof and who you call if something needs service.

Red flags we often find

The patterns that cost homeowners the most

We see a lot of proposals. These are the four issues that show up again and again — and the ones a second set of eyes catches before they're locked into a 25-year agreement.

Inflated savings projections

Headline savings that assume utility rates climb forever, ignore NEM 3.0 export credits, or quietly bake in incentives you may not qualify for. We re-run the math against approximate SCE (~$0.36/kWh), SDG&E (~$0.47/kWh), or PG&E (~$0.42/kWh) averages and your real bill.

Vague or swappable equipment

"Premium panels" with no brand, an inverter listed only by category, or a battery referenced without a model number. If the contract doesn't name the hardware, the installer can substitute lower-tier parts and you'd have no recourse.

Hidden dealer fees

A financed price thousands above the cash price, with the gap buried as a 'dealer fee' to buy down a flashy low APR. The advertised rate looks great; the total you pay does not. We separate the two so you can see the real cost.

No battery under NEM 3.0

A solar-only design sold with old-rules savings claims. Without storage, much of your daytime export earns very little back. If the quote doesn't even discuss a battery, that's a signal the savings story may not hold up.

Why quotes vary

Why solar quotes vary so much in California (2026)

Three proposals for one house can land thousands of dollars apart and all be 'correct' — because they are rarely quoting the same equipment, the same crew, the same scope, or the same product. These six things explain almost every gap we see.

Dealer fees and financing markups

A low advertised APR is often paid for with a dealer fee folded into the financed price, so the same hardware can be thousands more on a loan than for cash. A $0-down lease or PPA is priced differently again — the financier owns the system and can pass its commercial §48E credit through as a lower payment — so its monthly number is not comparable to a purchase price. Always ask for the cash price and the financed price side by side.

Equipment tier

Tier-one panels, a name-brand inverter, and a specified battery model (a Tesla Powerwall 3, for example) cost more than unnamed 'premium' parts that can be swapped later. Warranty length and who backs it ride along with the brand. Two quotes that look far apart may simply be pricing different generations of hardware.

In-house crews vs. subcontracted installs

Some quotes come from sales-only companies that resell the install to a subcontractor, adding a layer of margin or, at the other extreme, cutting price by handing your roof to whoever bids lowest that week. Who holds the license, who does the work, and who honors the workmanship warranty all move the number.

Roof type and layout

Concrete and clay tile, common across Southern California, takes more labor and hardware than composition shingle. Steep pitches, multiple small roof planes, shading, and a roof that needs repair before panels go on all add scope. One quote may have priced your roof; another may have assumed a simple one.

Permits, plan check, and your utility

Every city or county building department (the AHJ) sets its own plan-check fees, inspection rules, and turnaround, and each utility has its own interconnection paperwork. Older homes often need a main-panel upgrade before the utility will approve the system. Some quotes include all of that; some list it as 'not included'.

Whether a battery is included under NEM 3.0

Under NEM 3.0 the credit for exporting daytime solar is low, so most sound 2026 designs pair panels with a battery. A solar-only quote will always look cheaper than a solar-plus-battery quote for the same home — it is not the same product. Compare solar-plus-battery to solar-plus-battery, or the cheaper quote is just an incomplete one.

Same house, three quotes — an 8 kW system at $2.50–$3.50 per watt
Quote	Price per watt	8 kW total (before battery & financing)	What usually explains it
Quote A	$2.50/W	$20,000	Bottom of the range. Often standard-tier equipment, a simple composition roof, and no battery or panel upgrade in scope — confirm nothing is 'not included'.
Quote B	$3.00/W	$24,000	Middle of the range. Typically named tier-one hardware, an in-house crew, and permits and standard electrical work priced in.
Quote C	$3.50/W	$28,000	Top of the range. Usually explained by a tile or complex roof, a main-panel upgrade, premium equipment, or a dealer fee inside a financed price — ask which.

Illustration only, not a quote. The $2.50–$3.50 per watt range is the widely cited 2026 figure for California residential solar installed before battery storage and financing — the same range in our California solar cost guide. Totals are simply price per watt × 8 kW. To convert your own quote, divide its price by the system size in watts; our cost-per-watt guide shows where each equipment tier lands.

The fix is not to chase the lowest number — it is to make every quote answer the same six questions and then compare price per watt for the same scope. Our financing page explains what a cash, loan, or lease/PPA price actually contains, and a local advisor will do the translation for you at no cost: upload any proposal on our estimate form and you get an itemized read of where it lands and why.

Questions

Second-opinion FAQs

Yes. Send us any solar or battery proposal you've received and a local OC Solar advisor will review it line by line at no cost. There's no pressure to switch and no obligation to buy from us — if your existing quote is genuinely strong, we'll tell you so. The goal is to make sure you can sign with confidence, whether that's with us or someone else.

The most useful thing is the written proposal or contract itself — that's where the system size, equipment brands, price, financing terms, and production estimate live. Your most recent utility bill helps us sanity-check the production and savings math against your real usage. You can upload these on our estimate form, or call us and we'll walk through them with you.

No. An honest review only works if it's honest. We'll flag the things that genuinely concern us — vague equipment, hidden dealer fees, a production estimate that ignores NEM 3.0 — and we'll also point out anything the other quote got right. We're a licensed California contractor (CSLB #1023627); our reputation depends on giving you the straight version.

Under NEM 3.0, the credit you earn for exporting daytime solar to the grid is far lower than it used to be, so a solar-only system that looks great on paper can underdeliver in practice. A battery lets you store your own daytime production and use it at night instead of buying expensive grid power. Any quote that projects big savings on a solar-only system without addressing NEM 3.0 deserves a closer look.

Because the quotes are rarely for the same thing. The biggest gaps usually come from six places: a dealer fee or financing markup folded into the financed price, the tier of panels, inverter, and battery specified, whether the company installs with its own crews or subcontracts the work, how much labor your roof type and layout add, what the local permit and utility interconnection require, and whether a battery is included at all. Divide each quote's price by its system size in watts to get a price per watt, then confirm all three cover the same equipment, the same electrical scope, and the same battery before you compare the totals.

Widely cited 2026 ranges put a typical California residential solar installation at roughly $2.50 to $3.50 per watt installed, before a battery and before financing. That per-watt figure includes labor, permits, and standard electrical work. On an 8 kW system that works out to about $20,000 to $28,000. A quote outside the range is not automatically wrong, but it should be explained by something you can see on the paperwork, such as premium equipment, a tile roof, a main-panel upgrade, or a dealer fee. Treat the range as a benchmark, not a quote; your real number depends on your roof, usage, and equipment.
