Question 1

Is solar still worth it in California in 2026?

Accepted Answer

Yes — but the math changed. Under NEM 3.0 utilities pay much less for exported solar, so the value now comes from pairing solar with a battery to power your home during the expensive 4–9 PM peak instead of buying from the grid. With rising utility rates, a solar-plus-battery system typically pays back in about 7–9 years.

Question 2

Is the 30% federal solar tax credit gone?

Accepted Answer

For homeowners who buy with cash or a loan, yes — the federal residential credit (IRC §25D) expired December 31, 2025. The 30% value still exists on $0-down lease/PPA plans, where the financing company claims the commercial §48E credit and passes the savings to you as a lower payment (through about 2027). Anyone advertising a 30% homeowner tax credit in 2026 is out of date.

Question 3

How long does it take to go solar with OC Solar?

Accepted Answer

Install itself is usually 1–2 days. Our median is about 30 days from signing to install and about 60 days from signing to Permission to Operate — total time depends on city permitting and utility interconnection, which we manage end-to-end and report on weekly. We'll give you a realistic timeline up front — no surprises.

Question 4

Do I need a battery, or just solar panels?

Accepted Answer

In California's NEM 3.0 environment, a battery is what makes solar pencil for most homes — it stores your cheap daytime solar to offset expensive evening rates and keeps your home powered during outages. We'll size the right combination for your usage.

Question 5

What happens if my solar company goes out of business?

Accepted Answer

Your manufacturer warranties (Tesla, Enphase, Q CELLS, REC) are tied to the equipment and survive regardless of any installer. With OC Solar you also get an established company (founded in 2016) that grew while competitors closed, plus independently-backed workmanship coverage — so your protection isn't dependent on us being here, even though we plan to be.

Question 6

What areas does OC Solar serve?

Accepted Answer

We're headquartered in Irvine and serve Orange County and broader Southern California from eight offices, including Los Angeles, Ontario, Temecula, San Diego, Fresno, Bakersfield, and Palm Springs.

Question 7

Is my roof a good fit for solar?

Accepted Answer

Most Southern California roofs are. We model your actual roof, shading, and usage in Aurora before recommending anything — never a copy-paste layout. Complex or partially shaded roofs usually just call for the right inverter architecture, not a smaller system. And if your roof is near the end of its life, we'll tell you honestly and can replace it first as an Owens Corning Roofing Preferred Contractor.

Question 8

Does OC Solar offer financing?

Accepted Answer

Yes — several paths: pay cash for the lowest lifetime cost, own it with a $0-down solar loan (ENFIN or GoodLeap), go $0-down with a lease/PPA through LightReach by Palmetto, or — if credit is a concern — a prepaid plan through Participate Energy with no credit check. On lease, PPA, and prepaid plans the financier claims the commercial §48E credit and passes roughly 30% of value through as lower pricing.

Question 9

What services does OC Solar offer besides solar panels?

Accepted Answer

Battery storage (Tesla Powerwall 3 and Enphase IQ Battery), the Tesla Solar Roof as a Tesla Premier Certified installer, premium shingle roofing as an Owens Corning Roofing Preferred Contractor, Level 2 EV charger installation, commercial and multifamily solar, and repair service for existing systems — plus heat pumps coordinated through licensed HVAC partners.

Question 10

How much do solar panels cost in California in 2026?

Accepted Answer

Widely cited 2026 estimates put a typical California residential system around $15,000–$30,000 before financing, with a battery adding meaningfully on top. Treat that as a ballpark, not a quote: system size, equipment tier, roof complexity, and electrical work all move the number. That's why OC Solar quotes a single itemized proposal instead of a flyer price — the free estimate is the only figure that's accurate for your home.

Question 11

How is solar priced — per panel or per watt?

Accepted Answer

Per watt. California installers quote by system size in kilowatts at a price per watt, commonly landing somewhere around $2.50–$3.50 for residential solar before financing or battery. That's why two homes with the 'same number of panels' can have very different totals — panel wattage, equipment tier, and electrical scope all change the math.

Question 12

How much does a battery add to the cost of solar?

Accepted Answer

It depends on how much storage you need — capacity, backup goals (essentials versus whole home), and your electrical setup drive the number, so we quote the battery as a separate itemized line you can see. A battery raises the up-front cost, but under NEM 3.0 it's what makes solar actually save money: you use stored daytime power during the expensive 4–9 PM peak instead of exporting it for a low credit.

Question 13

What drives a solar quote up or down?

Accepted Answer

Five things move pricing the most: system size (how much electricity you use), panel and inverter tier, whether you add battery storage and how much, roof complexity — tile is more labor than composition shingle, and steep or multi-plane roofs cost more — and electrical upgrades like a main-panel swap or a sub-panel for backup loads. An itemized proposal shows you each piece.

Question 14

What's the payback period for solar in California?

Accepted Answer

For a correctly sized solar-plus-battery system, most California homeowners see payback in roughly 7–9 years. That's an estimate, not a guarantee — it assumes utility rates keep escalating around 5% annually and shifts with your utility, usage, and design, so individual results vary. After break-even, the system keeps producing on equipment warrantied for 25+ years.

Question 15

Can I go solar with $0 down?

Accepted Answer

Yes, two ways: a $0-down lease/PPA through LightReach by Palmetto, where the financier owns and maintains the system and you pay one low monthly rate, or a $0-down solar loan through ENFIN or GoodLeap, where you own the system from day one. If credit is a concern, Participate Energy's prepaid plan has no credit check and no lender. We'll show the real numbers on each path side by side.

Question 16

Is it cheaper to buy or lease solar in 2026?

Accepted Answer

Cash purchase has the lowest lifetime cost and fastest payback, but buyers no longer get a federal tax credit (§25D expired December 31, 2025). A lease or PPA needs nothing down, includes maintenance, and captures the federal §48E value — the financier claims the credit and passes roughly 30% through as a lower payment. Which wins depends on your cash, credit, and how long you'll stay in the home.

Question 17

Why do solar quotes vary so much between companies?

Accepted Answer

Usually because they're not quoting the same thing. A cheaper-looking bid often drops the battery NEM 3.0 economics require, assumes a lower equipment tier, or skips electrical work you'll be charged for later — and in 2026, some proposals still quietly assume the expired homeowner tax credit. Compare solar-plus-battery to solar-plus-battery at the same scope. We review competing quotes free.

Question 18

Does a bigger solar system always save more?

Accepted Answer

No. Under NEM 3.0, exported surplus earns very little, so oversizing the array to dump power onto the grid wastes money. The smarter design sizes the array to cover your usage and charge a battery for the 4–9 PM peak — a right-sized system costs less up front and saves more than the 'add more panels' pitch.

Question 19

Did the solar tax credit expire in 2026?

Accepted Answer

The federal residential solar tax credit (IRC §25D) expired on December 31, 2025 — homeowners who buy a system with cash or a loan in 2026 cannot claim it. The commercial §48E credit did not expire: on a lease, PPA, or prepaid plan, the financier owns the system, claims §48E, and passes roughly 30% of the value through to you as a lower price, generally through about 2027. It's a price benefit built into the plan — not a credit on your own tax return.

Question 20

What solar incentives are still available in California in 2026?

Accepted Answer

Three real ones: the federal §48E credit on $0-down lease/PPA and prepaid plans (claimed by the financier and passed through as roughly 30% lower pricing, through about 2027), California's SB 710 property-tax exclusion for systems qualifying before January 1, 2027, and the NEM 3.0 battery economics themselves. The 30% homeowner credit (§25D) expired December 31, 2025, and broad SGIP battery rebates closed with it.

Question 21

Is there a federal solar tax credit for homeowners in 2026?

Accepted Answer

No. The federal Residential Clean Energy Credit (IRC §25D) — the 30% credit for systems you buy with cash or a loan — expired for systems placed in service after December 31, 2025. Any company still advertising a 30% homeowner tax credit in 2026 is out of date. The surviving federal value lives in third-party-owned plans through the commercial §48E credit.

Question 22

What is the §48E credit and how does it lower my price?

Accepted Answer

§48E is the federal clean-electricity investment credit available to commercial owners. On a lease, PPA, or prepaid plan, the financing company owns your system, claims §48E, and passes the value — roughly 30% — to you as a lower payment or rate, through about 2027. It's a price benefit baked into the plan, not a tax credit you file for.

Question 23

Will solar raise my property taxes in California?

Accepted Answer

No — California excludes the added home value of an active solar system from property-tax reassessment, and SB 710 made that exclusion permanent for systems qualifying before January 1, 2027. In plain terms: add solar without raising your property tax bill. Confirm your specific situation with a tax professional before signing.

Question 24

Does California have a state solar tax credit?

Accepted Answer

No. California has no state solar income-tax credit. The state-level benefits are the SB 710 property-tax exclusion (for systems qualifying before January 1, 2027), net billing under NEM 3.0, and certain utility or local programs that vary by territory. We'll tell you which actually apply at your address.

Question 25

Can I still get an SGIP battery rebate in 2026?

Accepted Answer

Probably not. SGIP's general-market and equity budgets largely closed at the end of 2025; only limited income-qualified pathways may remain — for example households meeting income thresholds, in high-fire-threat areas, or with critical medical electricity needs. We'll check your eligibility honestly, and the battery's value stands on time-of-use savings and backup power either way.

Question 26

What is NEM 3.0 and how does it change my savings?

Accepted Answer

NEM 3.0 — the Net Billing Tariff covering SCE, SDG&E, and PG&E interconnections after April 15, 2023 — cut what utilities pay for exported solar by roughly 75%. The savings now come from storing your daytime solar in a battery and using it during the expensive 4–9 PM peak instead of selling it back cheaply. It's why nearly every system we design includes storage.

Question 27

A company is advertising a 30% homeowner tax credit. Is that legit?

Accepted Answer

No — for cash and loan buyers that credit expired December 31, 2025. A proposal that still assumes it either misstates your net cost by thousands or confuses the expired §25D credit with the §48E credit only a financier can claim on a lease/PPA. Treat it as a red flag — and get the quote reviewed. We review competing quotes free.

Question 28

How long will the §48E pass-through be available?

Accepted Answer

Through roughly 2027 under current law. The financier claims the commercial §48E credit on third-party-owned systems — leases, PPAs, and prepaid plans — and passes the value through as lower pricing. If you want that roughly-30% federal value reflected in your price, the practical window is now; we'll confirm current availability when we build your proposal.

Question 29

Do businesses still get a federal solar tax credit in 2026?

Accepted Answer

Yes. The commercial §48E investment credit remains available for business-owned systems through roughly 2027 — a key difference from the expired residential §25D credit. A business that owns its system may claim it directly. Tax treatment depends on your specific situation, so confirm details and timing with a qualified tax professional.

Question 30

Will my solar panels work during a power outage?

Accepted Answer

Not by themselves. Grid-tied solar shuts down during an outage for safety, so a blackout leaves a panels-only home dark even on a sunny day. A battery like the Tesla Powerwall 3 keeps essentials — or your whole home, depending on sizing — running through PSPS shutoffs and storm outages, then recharges from your panels the next day.

Question 31

Why is 4–9 PM the most expensive time for electricity?

Accepted Answer

Demand peaks in the evening as everyone gets home, right as solar production falls with the sun — so the grid is most strained. California's investor-owned utilities price that window highest on time-of-use plans. It's also exactly the window a battery is designed to cover: store cheap midday solar, discharge it during the peak.

Question 32

How does a battery actually save money under NEM 3.0?

Accepted Answer

By timing. Exported daytime solar earns a low credit under NEM 3.0, while evening grid power is the most expensive you buy. A battery charges on your cheap midday solar and discharges during the 4–9 PM peak, so you stop buying power at the highest rates. That daily shift is where modern California solar savings come from.

Question 33

How many Powerwalls do I need to back up my house?

Accepted Answer

A single Powerwall 3 — 13.5 kWh of storage and 11.5 kW of continuous power — backs up most small-to-medium Southern California homes; larger homes typically pair two to three units, and up to four can run in parallel. We design for whole-home or essential-loads backup based on your real loads, not a template.

Question 34

Tesla Powerwall 3 or Enphase IQ Battery 10C?

Accepted Answer

Powerwall 3 is an all-in-one unit with the solar inverter built in, 11.5 kW of continuous power, and 185 LRA motor-starting for AC compressors. The Enphase IQ Battery 10C is a cobalt-free LFP AC-coupled system with 10 kWh of usable capacity, 7.08 kVA of continuous power, a 15-year warranty, and quiet passive cooling. Both are excellent — the right one depends on your loads, space, and existing equipment.

Question 35

Can I add a battery to solar I already have?

Accepted Answer

Yes. The Enphase IQ Battery AC-couples to most existing systems regardless of who installed them, and we retrofit Powerwall onto many setups after confirming compatibility. It's one of the most common upgrades we do for homeowners whose solar predates NEM 3.0 economics — and it works even if your original installer is no longer around.

Question 36

How do I know if I'm on NEM 3.0?

Accepted Answer

If you applied for interconnection with SCE, SDG&E, or PG&E after April 15, 2023, you're on NEM 3.0 (the Net Billing Tariff). Municipal utilities like LADWP set their own net-metering and rate rules, which can differ substantially. We read your actual utility bill and design to whichever tariff serves your address.

Question 37

What's the difference between whole-home and essentials-only backup?

Accepted Answer

Whole-home backup keeps everything running, which takes more stored energy and power — often multiple batteries for a larger house. Essentials-only backs up a chosen subset (refrigerator, lights, Wi-Fi) through a backup sub-panel, so a smaller battery lasts longer in an outage. We size for whichever you actually need based on your real loads, without overselling capacity.

Question 38

How long will a battery run my home in an outage?

Accepted Answer

It depends on what you're powering. A Powerwall 3 holds 13.5 kWh of usable energy, so essentials-only backup stretches far longer than whole-home use with air conditioning running. Paired with solar, the battery recharges each day, so backup isn't limited to a single charge — and Tesla's Storm Watch pre-charges automatically before forecast outages.

Question 39

What are the steps to go solar with OC Solar?

Accepted Answer

Five: design and signing (days 1–3, with your dedicated project manager assigned day one), permits and approvals (about 2–4 weeks, handled by us), install day (typically 1–2 days), city inspection (about 1–2 weeks), and utility Permission to Operate. We prepare every form and report status weekly — the permit, inspection, and PTO steps run on your city's and utility's calendars, which we manage but can't skip.

Question 40

How long does it take to go solar from signing to power-on?

Accepted Answer

Our median is about 30 days from signing to install and about 60 days from signing to Permission to Operate — though city permit queues and utility timelines vary, and those steps are outside any installer's direct control. The install itself usually takes 1–2 days. We give you a realistic timeline up front and a status update every week.

Question 41

Do I have to pull the permit or deal with my utility?

Accepted Answer

No. We prepare and submit every permit form, schedule and meet the city inspector, and file your interconnection and PTO applications in-house — you do nothing except read the weekly updates. Knowing local permit offices and utility processes is where an established local installer earns its keep: fewer rejections, fewer delays.

Question 42

What is Permission to Operate (PTO)?

Accepted Answer

PTO is your utility's final authorization to switch the system on and connect to the grid. It comes after the building inspection passes, is granted on the utility's own timeline — often the longest single wait in the process — and your system must stay off until it arrives. We submit the application, push it through, then activate your system and set up monitoring.

Question 43

Why can't I turn my system on right after install day?

Accepted Answer

Because the utility hasn't authorized it yet. After install, the city must inspect the work and your utility must grant Permission to Operate — turning on before PTO isn't permitted. The wait is on their calendars, not ours, which is why we flag exactly which steps the city and utility control and update you weekly until power-on.

Question 44

What happens if the city inspection finds an issue?

Accepted Answer

We fix it fast. We schedule and meet the inspector ourselves and handle any corrections same-week, so you're not stuck waiting through an open-ended punch list. Because every job is run and warrantied by OC Solar with in-house crews, there's no subcontractor to chase — one company is accountable for passing your inspection.

Question 45

Does my city offer instant solar permits (SolarAPP+)?

Accepted Answer

Some California jurisdictions use SolarAPP+ for near-instant automated permitting; others review plans manually, which can take a few weeks. That's the biggest reason permit timelines vary city to city. We prepare each package to your jurisdiction's specific requirements to avoid avoidable rejections, whichever process your city runs.

Question 46

Do you handle SCE, SDG&E, PG&E, and municipal utilities?

Accepted Answer

Yes — all three investor-owned utilities, plus municipal utilities like LADWP that set their own net-metering and rate rules. The interconnection paperwork, rate-plan implications, and battery strategy differ by utility, so we design and file to the rules of whichever utility actually serves your address. Our eight offices span SCE, SDG&E, PG&E, and LADWP territory.

Question 47

Who manages my project day to day?

Accepted Answer

A dedicated OC Solar project manager, assigned the day you sign. One company, one point of contact from design to power-on — every job is run and warrantied by OC Solar with in-house crews, and you get a status update every week until your system is on.

Question 48

Which solar panel brands does OC Solar install?

Accepted Answer

Our flagship is the Tesla T420S — a 420 W, all-black, low-profile module — alongside Q CELLS Q.TRON BLK M-G2+ (N-type TOPCon, up to 440 W) and REC Alpha Pure-RX (heterojunction, up to 470 W). All are tier-1, all-black panels with 25-year warranties, and we recommend the combination that fits your roof and budget.

Question 49

What's the difference between TOPCon and heterojunction (HJT) panels?

Accepted Answer

Both are modern N-type cell technologies that produce more and age slower than older p-type panels. Q CELLS' TOPCon (Q.ANTUM NEO) reaches 22.5% efficiency with at least 90.58% power at year 25; REC's HJT cells are lead-free, reach 22.6% efficiency, and hold a best-in-class −0.24%/°C temperature coefficient with 92% power at year 25 — the edge on hot roofs.

Question 50

How long do solar panels actually last?

Accepted Answer

The panels we install are warrantied for 25 years of product and performance, and degradation is slow and published: the Tesla T420S is guaranteed 98% of rated power after year one and 85% at year 25; REC Alpha Pure-RX guarantees 92% at year 25. These are modules built for SoCal heat and 25+ years on your roof — the warranty is the floor, not the ceiling.

Question 51

Which inverter is best — Enphase, SolarEdge, or Tesla?

Accepted Answer

Whichever fits your roof and goals. Enphase IQ8 microinverters put conversion on every panel — maximum redundancy and shade tolerance, 25-year warranty. SolarEdge pairs per-panel optimizers (25-year) with one efficient central inverter — strong on complex, shaded roofs. Powerwall 3 builds the inverter into the battery, the right call when storage is part of the design. We model your actual roof in Aurora before recommending.

Question 52

What makes the Tesla Powerwall 3 different from other batteries?

Accepted Answer

The solar inverter is built in — one wall unit converts your solar, stores 13.5 kWh, and delivers 11.5 kW of continuous power with 185 LRA motor starting for AC compressors. It accepts up to 20 kW of solar across six MPPTs, scales to four units in parallel, and Storm Watch pre-charges automatically before forecast outages. We install it as a Tesla Premier Certified team.

Question 53

Do solar panels lose power in Southern California heat?

Accepted Answer

All panels produce slightly less as they heat up, which is why the temperature coefficient matters here. The panels we install are among the best on this spec: REC Alpha Pure-RX at −0.24%/°C, Q CELLS Q.TRON at −0.30%/°C, and Tesla T420S at −0.331%/°C. A low coefficient means more output through SoCal summer afternoons — exactly when power is most valuable.

Question 54

What is the Tesla Solar Roof, and who is it for?

Accepted Answer

It's a building-integrated system that replaces your roof and your panels at once: tempered-glass solar tiles plus visually matched steel tiles form one seamless surface rated Class A fire, Class 4 hail, and up to 194 mph design wind. It shines when you need a new roof anyway and want integrated solar with a premium look; if your roof is sound, traditional panels usually deliver more watts per dollar.

Question 55

Can OC Solar replace my roof as part of the project?

Accepted Answer

Yes. We're an Owens Corning Roofing Preferred Contractor installing TruDefinition Duration and Oakridge architectural shingles — with Class 4 impact-resistant options via Duration STORM. Re-roof and solar are planned, installed, and warrantied as one project by one team — which avoids paying to remove and re-install panels if the roof fails mid-warranty.

Question 56

Which EV chargers does OC Solar install?

Accepted Answer

The Tesla Wall Connector for Tesla vehicles and universal Level 2 chargers with the standard J1772 connector for other EVs — wired on a dedicated 240-volt circuit by our in-house electricians under CSLB #1023627. We run a load calculation on your panel first and tell you before any work whether you need an upgrade or load-management hardware.

Question 57

How do I monitor what my system is producing?

Accepted Answer

Every install includes 24/7 monitoring through the manufacturer's app, and both Enphase and SolarEdge report panel-by-panel production — so a sagging module shows up in the data, not as a surprise on your bill. We back that with a written production guarantee: if the system underproduces against the contracted estimate, that's our problem to fix.

Question 58

Do solar panels need maintenance or cleaning?

Accepted Answer

Very little. Solar panels have no moving parts, and in most of Southern California seasonal rain rinses off the dust that settles between storms, so routine washing usually isn't necessary. The more important upkeep is watching performance, which is automatic here: every install includes 24/7 monitoring through the manufacturer's app, so a panel that underproduces shows up in the data. If anything does need attention, you call OC Solar's own in-house service team — there's no subcontractor or third party to chase — and we're built to support your system for the next 25 years.

Question 59

What warranties come with an OC Solar system?

Accepted Answer

Three layers: manufacturer warranties on the hardware (25 years on panels, 25 years on Enphase microinverters, 10 years on Powerwall 3, 15 years on the Enphase IQ Battery 10C), OC Solar's workmanship warranty on the installation itself, and a written production guarantee with 24/7 monitoring. We'll walk you through exactly what each covers before you sign.

Question 60

What's the difference between a manufacturer warranty and a workmanship warranty?

Accepted Answer

Manufacturer warranties cover the equipment — panels, inverter, battery — and are tied to the product, so they survive even if the installer disappears. A workmanship warranty covers how it was installed: roof penetrations, wiring, flashing, service visits. That layer is only as good as the company behind it, which is why financial stability matters more than the lowest bid.

Question 61

What is a production guarantee?

Accepted Answer

A written commitment that your system will produce what the contract says. We model your roof and usage, give you a written production estimate, and monitor the system 24/7 — if it underproduces against the contracted estimate, that's our problem to fix, not yours. You can watch real performance yourself in the app at any time.

Question 62

What's the warranty on a Tesla Powerwall 3?

Accepted Answer

Ten years, with unlimited cycles and at least 70% capacity retained — covering the integrated solar inverter as well, since it's part of the unit. One honest detail many installers skip: the warranty requires the Powerwall to stay connected to the internet. The Enphase IQ Battery 10C alternative carries a 15-year, 6,000-cycle warranty at ≥60% capacity.

Question 63

What is REC ProTrust, and why does a 25-year labor warranty matter?

Accepted Answer

REC ProTrust covers the Alpha Pure-RX panel for 25 years of product, performance, and — rarely in solar — labor, so a warranty replacement doesn't cost you the service visit. It applies when the system is installed and registered by a REC Certified Solar Professional (systems under 25 kW); otherwise REC's standard 20/25 coverage applies. We'll confirm what your specific design qualifies for.

Question 64

What ratings and reviews does OC Solar have?

Accepted Answer

4.9 stars across 400+ Google reviews, 4.7 stars across 451 Yelp reviews, and a BBB A+ rating — plus recognition on Solar Power World's 2025 Top Solar Contractors list and Panasonic's Top Residential Installer of the Year for Southern California in 2023. We show ratings from multiple platforms and respond to criticism publicly rather than curating a wall.
