Not in California?

California pays 30 to 35¢ for grid power and 4 to 8¢ for the solar you export. That gap is the whole story: on the big three utilities, batteries went from upgrade to prerequisite, while LADWP customers still enjoy the retail-rate deal the rest of the state lost.

About EcoGen America

In California, Your Meter Decides the Math.

Since April 2023, new solar customers on PG&E, SCE and SDG&E sit on the Net Billing Tariff: exports are priced hourly at roughly 4 to 8¢ while retail power costs 30 to 35. The gap is why a battery is no longer optional equipment on those utilities; storing your own power beats selling it by a factor of five.

But California is not one market. LADWP customers in Los Angeles still earn retail-rate net metering credits, the deal the rest of the state lost, and SMUD in Sacramento runs its own programs outside CPUC rules entirely.

Two more wrinkles: your export rate locks to your interconnection vintage for nine years, and households already on NEM 2.0 keep their 20-year legacy terms unless an expansion triggers a new interconnection, a mistake no one should make casually.

EcoGen America starts where the money starts, with who runs your meter, then models the battery math honestly and matches you with installers who design for the tariff you are actually on.

Our vetting process

Tariff-First Network

Every installer we list designs for the Net Billing Tariff or your municipal alternative, not for the net-metering world that ended in 2023.

Quote Analysis

Built-in checks for solar-only quotes on NBT utilities, dead SGIP promises, and designs that would break a NEM 2.0 legacy lock.

Utility-Specific Numbers

PG&E, SCE, SDG&E, LADWP and SMUD each run different rules. We model the one on your meter, including the ACC Plus adder where it exists.

Privacy First

Your information goes only to the installers you choose to hear from. Nothing is resold.

Thirty Cents In, Six Cents Out

Export pricing per the CPUC Net Billing Tariff using the Avoided Cost Calculator; your rate locks to your interconnection vintage for nine years. Battery-inclusive systems run $25,000 to $45,000 before incentives and pay back in 7 to 10 years. Consistent with our California incentives guide.

The corollary most quotes skip: on the big three, a solar-only system exports its best afternoon production at the worst price. If a proposal has no battery and no self-consumption story, it was designed for 2022.

Meter, Battery, Vintage: The California Sequence

1

Identify

CPUC utility or municipal? The answer changes everything downstream, from export rates to whether a battery is essential or optional.

2

Pair

On PG&E, SCE and SDG&E, design battery-first: store the afternoon, spend it in the evening, export only what is left.

3

Protect

Your export rate locks to your interconnection date for nine years, and NEM 2.0 households risk their 20-year legacy terms by expanding carelessly. Timing is part of the design.

The Los Angeles and Sacramento Exceptions

The 2023 export cut applied to CPUC-regulated utilities. Californians on municipal power live under different rules, and some of them are better.

  • LADWP still pays retail. Los Angeles municipal customers earn full retail-rate net-metering credits, the arrangement every other major California utility ended. For an LA homeowner who cannot size purely for self-consumption, this is the most valuable incentive left in the state, and it is why LADWP has not needed a rebate program since 2018.
  • SMUD writes its own rules. Sacramento’s utility runs its programs entirely outside CPUC jurisdiction. Check SMUD’s current compensation terms directly before trusting any statewide generalization, ours included.
  • NEM 2.0 legacies are gold; handle with care. Households interconnected before April 15, 2023 keep roughly 30-to-35¢ export credits for 20 years from their interconnection date. An expansion that triggers a new interconnection can forfeit that. Get tariff advice before touching a legacy system.
  • SGIP is mostly a memory for standard households. Most residential battery rebate categories are closed. A quote leaning on SGIP money should name the exact category and its current waitlist status.

California solar is not dead; it is bifurcated. Know which side of the line your meter sits on before comparing any two quotes. The full program map is in our California incentives guide.

California Contract Checks

The Questions That Break Bad California Quotes

Post-2023 California rewards buyers who interrogate the design, not the brochure. Four questions do most of the work.

Clause to verify: Make the proposal name your utility and tariff, and confirm the export rate and vintage lock used in the model.
Clause to verify: Ask for the self-consumption percentage the design achieves, with and without the battery. Numbers, not adjectives.
Clause to verify: For every incentive in the quote, ask: which program, which category, confirmed available this month? Then check.
Clause to verify: Get the annual escalator, the buyout schedule, and what a home sale requires of the buyer, all in writing.
Verify your paperwork

Four questions, any quote, any utility. California installers worth hiring answer them without friction.

Who Should Skip California Solar Right Now

The highest rates in the continental U.S. keep most California roofs viable. These are the exceptions, and they are bigger than the sales industry admits.

  • Solar-only budgets on the big three. If a battery is out of reach, the 4-to-8¢ export rate means a system that sells its best hours for pennies. Either budget the pair, roughly $25,000 to $45,000 all-in, or wait until you can.
  • NEM 2.0 households itching to expand. Your legacy terms are worth more than the new panels. Any change that triggers a new interconnection resets you onto the Net Billing Tariff; exhaust every non-triggering option first.
  • Buyers counting on SGIP. Most residential categories are closed. If the quote”s math needs a battery rebate to work, it does not work.
  • Heavy evening usage with no storage plan. The tariff punishes exactly this profile: buy at peak evening rates, export at midday lows. Fix the design or skip it.
  • Short tenure. Battery-inclusive payback runs 7 to 10 years. Selling sooner transfers the value, and any lease, to a buyer who must accept it at closing.

What still cannot hurt you: your property taxes. California”s 100% exclusion means a solar system adds no assessed value, statewide. Run your own scenario in our worth-it breakdown.

California Solar FAQs

Is solar still worth it in California after the export cut?

Yes, but the design changed. Retail power at 30 to 35¢ is the highest in the continental U.S., so offsetting your own usage still pays powerfully; exporting does not.

On PG&E, SCE and SDG&E that means battery-first design and a 7-to-10-year payback on the pair. On LADWP, solar alone still works the old way.

What exactly does the Net Billing Tariff pay for my exports?

Roughly 4 to 8¢/kWh, priced hourly through the CPUC’s Avoided Cost Calculator, with an adder boosting early years for PG&E and SCE customers but not SDG&E.

Whatever rate applies at your interconnection locks to your system for nine years, which makes your connection date part of the economics.

I’m on NEM 2.0. Can I add panels or a battery safely?

Carefully. Your legacy terms, roughly 30-to-35¢ credits for 20 years from interconnection, survive only as long as you avoid changes that trigger a new interconnection agreement.

Batteries can usually be added without losing the lock; system expansions are where people get burned. Get tariff-literate advice before signing anything.

Do Los Angeles homeowners really still get retail net metering?

Yes. LADWP is municipal, outside CPUC jurisdiction, and still credits exports at the retail rate, which is why LA is now the best rooftop-solar deal among major California cities.

SMUD in Sacramento is similarly independent but runs different terms; check directly.

Will solar raise my property taxes in California?

No. The state’s 100% property tax exclusion means the added value of a residential solar system is not assessed, anywhere in California.

That exclusion and the federal lease-side commercial credit are the last broad incentives standing after the 2026 changes.
