Solar pricing, 2026
Solar panel cost in Southern California, explained honestly.
Solar panel cost for most Southern California homes runs about $18,000–$32,000 gross for a typical 6–10 kW system before incentives — roughly $2.50–$3.50 per watt installed. Below we break down what you actually pay by system size, what moves the number up or down, and how financing replaced the expired federal tax credit.
What solar costs by system size.
These are gross price ranges before incentives, based on typical SoCal installs at $2.50–$3.50 per watt. Your roof, panel choice, and city will move you within — or occasionally beyond — these bands.
| System size | Best fit | Approx. gross cost |
|---|---|---|
| 5 kW | Smaller homes, low usage, or a starter offset | $13,000 – $17,500 |
| 6 kW | Common for a modest single-family home | $15,000 – $21,000 |
| 8 kW | The SoCal sweet spot for most households | $20,000 – $28,000 |
| 10 kW | Larger homes, pool pumps, or some EV charging | $25,000 – $35,000 |
| 12 kW | High usage, two EVs, or all-electric homes | $30,000 – $42,000 |
| + Battery | Tesla Powerwall 3 (most homes pair one under NEM 3.0) | + $13,500 – $17,500 |
All figures are estimates and ranges, shown gross before incentives. Your exact quote depends on your roof, system size, equipment, any electrical upgrades, and your city’s permit fees. We do not use these numbers as a price — we use them as a starting point for a real, line-item quote.
Financing
Good news: we have financing.
Whether you want to own your system or lease it, every Helios financing option starts at $0 down and $0 out of pocket — and for most homeowners, the monthly payment comes in lower than the electric bill it replaces. You trade an unpredictable, rising utility bill for a fixed payment on something you control.
$0
Down
Nothing to pay to get started.
$0
Out of pocket
No upfront check to write.
Lower monthly, most often
Typically less than your old electric bill.
Own your system
Finance the system toward full ownership with $0 down. You build equity instead of renting power, and you own it outright once it’s paid off — with the same 25-year panel warranty and 10-year workmanship guarantee on every install.
- $0 down, $0 out of pocket
- Build equity in your home
- Payment often below your old bill
Lease it (Propel prepaid-lease)
Prefer not to put a loan on your credit? Our prepaid-lease option is also $0 down and captures the federal commercial clean-energy credit — passing roughly 30% of the value through as a reduction up front. You take title to the system in year 6, and we handle monitoring and support the whole way.
- $0 down, $0 out of pocket
- ~30% commercial-credit value up front
- You take ownership in year 6
Financing offered through our lending partners on approved credit. $0-down terms and monthly amounts depend on system size, credit, and your utility rate — we show your exact numbers on your quote.
What actually drives your price.
Two homes on the same street can get very different quotes. Here is why — and which of these we can see before we ever climb on your roof.
Roof type and complexity
Composition shingle is the baseline. Spanish tile, S-tile, and wood shake need specialized mounting hardware and slower, more careful labor — they can add several thousand dollars. Steep pitches, multiple roof planes, and three-story access also raise the labor line.
System size (kW)
This is the single biggest lever. Bigger systems cost more in total but usually less per watt, because fixed costs like permitting and the trip to your roof get spread across more panels. We size to your actual usage — not to maximize the invoice.
Panel and inverter tier
We install Tier-1 monocrystalline panels (REC, Q CELLS, Silfab) with Enphase microinverters by default. Premium panels cost a little more per watt but carry stronger warranties and degrade slower. We never quote off-brand equipment to hit a lower sticker price.
Battery storage
Adding a Tesla Powerwall 3 typically adds about $13,500–$17,500 before incentives for one unit. Under NEM 3.0 most SoCal homeowners pair a battery with solar — but it is a separate, optional line you can see and decide on.
Electrical panel upgrades
Older homes with a 100-amp main panel or a full busbar sometimes need a panel upgrade or a load-side connection before solar (and especially a battery) can be added safely. When that applies, we show it as its own line — it is usually $2,000–$4,500.
Permitting and your city
Permit fees, plan-check requirements, and inspection timelines vary by jurisdiction. Some SoCal cities are fast and cheap; others add cost and weeks. We quote the real fee for your specific permit office rather than a generic estimate.
The incentive reality, stated plainly.
The 30% residential federal solar tax credit ended on December 31, 2025. If a company is still quoting you a price that assumes you’ll get that homeowner credit back at tax time, walk away — it no longer exists for systems you buy outright.
What still works is our prepaid-lease option, Propel. Our financing partner captures the federal commercial clean-energy credit and passes roughly 30% of the value through to you as a reduction up front. You take title to the system, in your name, in year 6. For many homeowners that’s actually better than the old credit, because it’s money off the top rather than a refund you wait for.
On batteries, the SGIP rebate is now limited to income-qualified households and fire-zone resiliency tiers, so most homeowners should budget without assuming a battery rebate. We’re not tax advisors — we’ll put every structure in writing and recommend you confirm it with yours.
Payback
When solar pays for itself.
Solar only
~10–14 yrs
Under NEM 3.0 on SCE, PG&E, and SDG&E, exported power is credited at a much lower rate, which stretches solar-only payback. Still a real return given SoCal rate inflation — just slower than the NEM 2.0 era.
Solar + battery
~6–9 yrs
Storing daytime production and using it during the 4–9 PM peak — instead of exporting it cheap — is what brings payback back down. It’s why most SoCal homeowners now pair a battery.
Municipal utilities differ: LADWP, Pasadena Water & Power (PWP), and Riverside Public Utilities (RPU) run their own net-metering and rate structures, so payback in those territories can be meaningfully different. We model your specific utility before quoting a payback number.
How we quote
Every line. No padded markups.
Most of the price horror stories in this industry come from quotes you can’t read — one big number with the markup baked in. We do the opposite. Your quote shows panels, inverter, mounting, labor, permitting, monitoring, and any battery or panel upgrade as separate lines.
Tim, the owner, personally signs off on every design and every quote before it reaches you. That’s the check that keeps the numbers honest — and it’s why we can show you cash, loan, and prepaid-lease economics side by side instead of steering you to whichever pays us most.
Solar cost questions, answered.
The pricing questions we actually get on discovery calls — answered without the sales spin.
- How much does solar cost in Southern California?
- Most Southern California homes need a 6–10 kW system, which lands between roughly $18,000 and $32,000 gross before any incentives or financing. That works out to about $2.50–$3.50 per watt installed. Smaller 5 kW systems can start near $13,000; larger 12 kW all-electric setups can reach the low $40,000s. These are ranges, not quotes — your exact number depends on roof type, system size, panel choice, whether you add a battery, and your city's permit fees. We give you a real line-item quote, not a teaser price.
- Is solar still worth it in 2026 after the federal tax credit ended?
- For most SoCal homeowners, yes — but the math changed and you should understand it. The 30% residential federal solar tax credit ended on December 31, 2025, so you can no longer claim it on a system you buy outright. What still works is our prepaid-lease option (Propel): our financing partner captures the federal commercial clean-energy credit and passes roughly 30% of the value to you as a reduction up front, and you take title to the system in year 6. Combined with SoCal's high and rising utility rates, solar — especially solar plus a battery under NEM 3.0 — still pencils out for most homes. We're not tax advisors; we put the structure in writing and recommend you confirm it with yours.
- How much does a solar battery add to the cost?
- A single Tesla Powerwall 3 typically adds about $13,500–$17,500 before incentives. Larger homes — or homes that want to back up air conditioning, a heat pump, or EV charging — often need two units, which roughly doubles that line. The SGIP battery rebate that used to lower this is now limited to income-qualified households and fire-zone resiliency tiers, so most homeowners should budget without assuming a rebate. We model solar-only and solar-plus-battery side by side so you can see exactly what the battery costs and what it saves.
- What's the price per watt for solar in SoCal?
- Typical Southern California residential installs run about $2.50–$3.50 per watt installed, gross, before incentives. A clean composition-shingle roof on a straightforward layout sits toward the low end; tile or shake roofs, multi-plane layouts, panel upgrades, and difficult access push toward the high end. Price per watt usually improves on larger systems because fixed costs are spread across more panels.
- What is the payback period on solar in Southern California?
- Under NEM 3.0 — the net-metering rules on SCE, PG&E, and SDG&E for systems permitted after April 2023 — solar-only payback typically runs about 10–14 years, because exported power is credited at a much lower rate than before. Adding a battery lets you use your stored daytime production during the 4–9 PM peak instead of exporting it cheap, which brings payback into roughly the 6–9 year range for most homes. Municipal utilities like LADWP, Pasadena Water & Power, and Riverside Public Utilities run their own programs, so the math there is different — we model your specific utility.
- How does financing work now that the tax credit is gone?
- You have the same core options as before — pay cash, take a solar loan, or use our prepaid-lease (Propel). The difference is where the ~30% comes from: instead of a residential tax credit you wait to claim, the prepaid-lease captures the federal commercial clean-energy credit and passes that value through as money off your cost up front, with title transferring to you in year 6. We show cash, loan, and prepaid-lease economics side by side on every quote so you can pick what actually fits your situation — not what pays us the most.
- Do you really offer $0-down solar financing?
- Yes. Both our ownership financing and our lease/prepaid-lease options are $0 down and $0 out of pocket to start — there's no upfront check to write. For most homeowners the monthly payment comes in lower than the electric bill it replaces, because you're financing a fixed asset instead of paying a utility rate that keeps climbing. Exact terms and the monthly amount depend on your system size, credit, and utility rate, and financing is offered through our lending partners on approved credit. We show your real numbers on your quote.
