Quick answer: The best solar companies in Simi Valley, CA in 2026 are NRG Clean Power, Ameco Solar, Shelter Roofing & Solar, Next Door Home Upgrades and August Roofing & Solar. Every license on this list was checked against CSLB records in October 2026. Solar in Simi Valley runs about $2.50 per watt, or roughly $18,800 for a typical 7.5 kW system, and SCE’s 4 to 9 PM peak rate is 59 cents per kWh. The 30% federal tax credit is gone for purchased systems, so design and battery strategy now decide your payback.
Simi Valley is the rare California city where the permit is not the problem. That is the first thing I would tell any homeowner here. The city was the third in California to adopt SolarAPP+ automated permitting back in November 2021, and it has required it for standard rooftop systems since January 1, 2023. A clean residential job gets its permit issued online and needs one inspection.
So when a Simi Valley quote drags, the delay is almost never City Hall. It is the installer. That makes picking the right company more important here than in cities where everyone waits on the building department anyway.
The other half of the Simi Valley story sits in the hills above town. The 2018 Woolsey Fire started at the Santa Susana Field Laboratory on the city’s southeast edge. The 2019 Easy Fire threatened the Reagan Library. In May 2026 the Sandy Fire burned 2,183 acres and forced about 33,000 evacuations. When Santa Ana winds blow, SCE can cut power to Simi Valley circuits under Public Safety Power Shutoffs. That is why battery backup is a real decision here, not an upsell.
This 2026 edition replaces our older Simi Valley roundup. We dropped companies that went bankrupt or could not show a valid license, added the genuinely local installers that do most of the work in Wood Ranch, Big Sky, Indian Hills and the older neighborhoods off Los Angeles Avenue, and rebuilt the price math for life after the federal tax credit.
Key takeaways
- Only 4 of the 10 companies below are headquartered in Simi Valley or Moorpark. Shelter Roofing & Solar alone shows 66 verified Simi Valley installs since 2019.
- Simi Valley homes get SCE delivery plus Clean Power Alliance generation by default. Your solar credits follow CPA’s rules, which pay 10% more on surplus than SCE.
- A purchased system completed after December 31, 2025 gets no federal tax credit. A lease or PPA can still carry a federal credit, priced into your monthly payment.
- California’s solar property tax exclusion ends for systems completed after December 31, 2026. Simi Valley’s same-day permits make a December finish realistic if you sign now.
- Under NEM 3.0, a battery moves payback on a 10 kW system from about 10 years to under 8 in our example below.
What makes Simi Valley a different solar market?
Simi Valley is a hot, inland, mostly single-family SCE market with fast permits and real outage risk. Here is the snapshot we use when we size a system in the city.
Simi Valley solar market snapshot (October 2026)
| Factor | Simi Valley detail |
|---|---|
| Utility | SCE delivery and billing; Clean Power Alliance (Lean Power, 40% clean) generation by default since February 2019 |
| Most common rate plan | SCE TOU-D-4-9PM: 59¢/kWh summer peak, 33¢ summer off-peak, 32¢ winter super off-peak |
| Fixed charge | $24.15/month Base Services Charge ($6.00 CARE, $12.08 FERA) |
| Sun resource | 1,712 kWh per kW per year at an ideal south-facing tilt (NREL PVWatts) |
| Installed price | About $2.49/W before incentives; 7.56 kW average system ≈ $18,842 |
| Permits | SolarAPP+ required for standard roof-mount PV up to 38 kW; one combination permit for PV, battery and panel upgrade; one inspection |
| Housing stock | 80% single-family; about 70% of homes built between 1960 and 1989; 72.9% owner-occupied |
| Grid risk | SCE PSPS shutoffs possible during Santa Ana winds; Woolsey (2018), Easy (2019) and Sandy (2026) fires all hit the Simi Hills |

The housing stock matters more than people think. A 1970s tract home off Erringer Road often has a 100 or 125 amp main panel and a 20 to 30 year old composition roof. Your installer should look at both before it quotes you a single panel. A Wood Ranch home built in the late 1980s or 1990s is more likely to have concrete tile and a 200 amp service, which changes the racking and labor price instead.
Who are the top 10 solar companies in Simi Valley?
NRG Clean Power ranks first for Simi Valley in 2026, followed by Ameco Solar, Shelter Roofing & Solar, Next Door Home Upgrades and August Roofing & Solar. The table below shows every company’s state license so you can check it yourself on the CSLB license lookup in about 30 seconds.
Best solar companies in Simi Valley, CA: 2026 comparison
| Rank | Company | CSLB license # | Licensed since | Based in | Best for |
|---|---|---|---|---|---|
| 1 | NRG Clean Power | 1026168 (B, C-10, C-20) | 2017 | Canoga Park, about 15 miles east | Best overall: price guarantee, solar + battery + roofing in one crew |
| 2 | Ameco Solar | 1053172 (B, C-10) | 2019 (Ameco name since 1974) | Valley Village | Long-track-record SFV installer |
| 3 | Shelter Roofing & Solar | 624196 (C-10, C-39) | 1991 | Moorpark | Roof and solar from a Ventura County roofer |
| 4 | Next Door Home Upgrades | 1054136 (B, C-10, C-39) | 2019 | Simi Valley | Enphase-focused local installer |
| 5 | August Roofing & Solar | 786740 (B, C-10, C-39) | 2000 | Simi Valley | Re-roof plus solar on older tract homes |
| 6 | Solar Solutions Company | 999310 (C-46) | 2014 | Simi Valley | Small owner-operated solar specialist |
| 7 | Plug It In Solar | 986882 (C-10) | 2013 | Van Nuys | High Simi Valley install volume |
| 8 | Sespe Power Solutions | 1055763 (C-10) | 2019 | Santa Paula and Ventura | Battery-forward Ventura County option |
| 9 | Semper Solaris | 978152 (B, C-10, C-20, C-39, C-46) | 2012 | El Cajon (San Diego) | Solar, roofing and HVAC under one contract |
| 10 | Sunrun | 750184 (B, C-10, C-39, C-46, C-47) | 1998 | San Francisco | Lease or PPA with no money down |
License data from CSLB records as mirrored on prelien.co and sitevetter.com, checked October 2026. Two mirrors disagreed on renewal dates for Shelter and Semper Solaris; both show active through 2028 in the newer data.
A note on license types: you do not need a C-46 (solar) license to install solar in California. A B (general) or C-10 (electrical) license covers the work. Most of the strongest local companies here hold C-10 or B, so do not let a salesperson tell you their C-46 makes them the only qualified option.
How we ranked these companies
We ranked on five things a Simi Valley homeowner can check: an active CSLB license with no disclosable actions, a physical office within driving distance of the city, a real install record in Ventura County, NEM 3.0 battery design capability, and honest pricing with no door-to-door pressure. Review volume counted, but a 5.0 from 15 reviews counted less than a 4.7 from 700.
Who we left out, and why
- Freedom Forever filed Chapter 11 in April 2026 and converted to Chapter 7 liquidation on August 7, 2026. If you have an unfinished Freedom Forever system, read our Freedom Forever bankruptcy guide.
- SunPower (the original company) went bankrupt in 2024. Today’s SunPower brand is a different company that bought the name.
- Tesla Energy still holds an active license (#888104), but Tesla discontinued Solar Roof in August 2026 and now sells most residential solar through certified third-party installers. CSLB also filed Accusation N2023-271 over three Solar Roof jobs. You can still get a Powerwall from most companies on this list.
- Baker Home Energy is an excellent installer, but it serves San Diego, Orange, Riverside and San Bernardino counties only, not Ventura County.
- Several Simi Valley listings that rank on Google, including a few sales offices and mailbox addresses, could not show a CSLB license number. We do not list those.
The 10 best solar installers in Simi Valley, reviewed
1. NRG Clean Power: best overall for Simi Valley
NRG Clean Power is our pick because it combines a short drive, in-house crews and a written price guarantee. Our Canoga Park office on Owensmouth Avenue is about 15 miles from central Simi Valley over the 118, so site visits, inspections and service calls do not wait for a crew from another county.
We have installed in Simi Valley for years. One recent job was a 6.15 kW system on a shingle roof using 15 REC 410 W panels, Enphase IQ8M microinverters and an Enphase battery. An earlier 7.03 kW system used SolarEdge inverters. That mix is typical for the city: microinverters on chopped-up tract roofs, string inverters on clean south-facing planes.
- License: CSLB #1026168 (B, C-10, C-20), active, no disclosable actions
- Services: solar, batteries (Tesla Powerwall, Enphase, FranklinWH), roofing, EV chargers, panel cleaning and repair
- Credentials: Tesla Certified Installer, EnergySage Elite, CNN Underscored Editors’ Pick, CNET badge, CALSSA member
- Reviews: 4.5 stars from 225+ Google reviews; 4.7 from 777 EnergySage reviews
- Pricing: best price guarantee against a comparable itemized quote; no door-to-door sales, virtual consultations available
The honest tradeoff: we are not always the lowest bid. If a quote comes in well below ours, check the equipment line by line before you decide. Some recent reviews also mention permitting and install timing; ask us for a written schedule at signing.
2. Ameco Solar: the long-track-record Valley installer
Ameco Solar is the oldest name on this list, with a lineage that goes back to 1974 in Los Angeles. The current company, Ameco Solar LLC, holds CSLB #1053172 (B, C-10) and works from Valley Village, a short trip to Simi Valley on the 118 or 101.
Ameco pairs solar with roofing and battery backup, reports more than 7,000 systems installed, and earned REC Certified Gold status in 2026. It rates 4.53 stars from 128 SolarReviews reviews. It offers purchase, loan and lease options through lenders such as GoodLeap and Mosaic.
Watch for: like most busy installers, some reviews mention slow communication after signing. Ask who your project manager will be before you commit.
3. Shelter Roofing & Solar: the Ventura County roofer that does solar
Shelter Roofing & Solar is based on Moorpark Avenue in Moorpark, the next city west, and has been in business since 1978. Its license, CSLB #624196 (C-10, C-39), dates to 1991.
Shelter shows 470 verified utility-connected installs, 379 of them in Ventura County and 66 in Simi Valley since 2019. It carries a 5.0 Google rating from 139 reviews and sells almost no leases. If your roof is near the end of its life, one company owning both the roof and the solar penetrations is a real advantage.
Watch for: no Tesla or Enphase certification is listed on its public profiles. If you want a Powerwall, confirm who installs and services it.
4. Next Door Home Upgrades: the Simi Valley Enphase specialist
Next Door Home Upgrades works from Guardian Street in Simi Valley’s industrial area and holds CSLB #1054136 (B, C-10, C-39), active since 2019. It shows 27 verified Simi Valley installs since 2021 and a 5.0 Google rating from about 90 reviews.
The company advertises Enphase Platinum and Tesla Certified status and also does roofing, windows and ventilation. For a small, local, high-touch installer, it is one of the strongest options in town.
Watch for: its website still promotes the 30% federal tax credit. That credit ended for purchased systems completed after December 31, 2025, so make sure your quote does not count it.
5. August Roofing & Solar: re-roof and solar on older homes
August Roofing & Solar is based on Cochran Street in Simi Valley, founded in 1991, and licensed under CSLB #786740 (B, C-10, C-39) since 2000. It holds Owens Corning Platinum Preferred status and NABCEP business certification, with roughly 4.9 stars from 300+ Google reviews.
August shows 219 verified utility-connected solar installs, 147 of them in Ventura County. It is a natural fit for 1960s and 1970s homes that need a new roof before panels go on.
Watch for: independent review analysis scores August lower on price transparency and long-term warranty support. Ask for warranty terms in writing; its site does not publish them.
6. Solar Solutions Company: the owner-operated local
Solar Solutions Company is a sole-owner solar contractor on Industrial Street in Simi Valley, licensed under CSLB #999310 (C-46) since 2014. It shows 265 verified utility-connected installs and a perfect 5.0 on Yelp from 36 reviews. It sells no leases.
Watch for: the license carries a workers’ compensation exemption, which usually means no W-2 employees. Ask who will be on your roof and whether subcontractors carry their own coverage.
7. Plug It In Solar: high Simi Valley volume from Van Nuys
Plug It In Solar, based in Van Nuys and licensed under CSLB #986882 (C-10) since 2013, shows 102 verified Simi Valley installs, the most of any company we checked. Volume like that means the crew has seen every roof type in the city.
Watch for: it is not a Simi Valley office. Confirm service response times for after-install issues.
8. Sespe Power Solutions: battery-forward Ventura County option
Sespe Power Solutions is headquartered in Santa Paula with a Ventura office, established in 2015 and licensed under CSLB #1055763 (C-10) since 2019. EnergySage lists it as Enphase Gold and Tesla Powerwall Certified, which makes it a solid choice if backup during PSPS events is your main goal.
Watch for: it is about 35 to 40 miles from Simi Valley, the farthest local office on this list.
9. Semper Solaris: solar, roof and HVAC under one contract
Semper Solaris is a veteran-owned company based in El Cajon that holds CSLB #978152 with B, C-10, C-20, C-39 and C-46 classifications. It is one of the few companies that can quote solar, a new roof and a heat pump on one contract.
Watch for: it is headquartered in San Diego County, and public records show 3 OSHA citations. Ask which office and crew will handle a Ventura County job.
10. Sunrun: the lease and PPA giant
Sunrun (CSLB #750184) is the largest residential solar company in the country, and almost all of its new business is lease, PPA or subscription. That matters in 2026: because Sunrun owns the system, it can still claim a federal credit and price it into your payment, which a cash buyer cannot.
Watch for: you do not own the system, the contract runs 20 to 25 years, and selling your home means the buyer must qualify to take over the agreement. Read our California solar financing guide before you sign a lease.
What do Simi Valley homeowners pay for electricity in 2026?
Most Simi Valley homes are on SCE’s TOU-D-4-9PM plan, where power costs 59 cents per kWh on summer weekdays from 4 to 9 PM and 32 to 36 cents the rest of the time. SCE’s average residential rate was 34.5 cents per kWh after the October 1, 2026 rate change, and a typical 500 kWh bill on TOU-D-4-9PM rose to $188.64, according to the SCE rate advisory.
SCE time-of-use rates for Simi Valley homes (current as of October 2026, before baseline credit)
| Plan | Summer peak | Summer off-peak | Winter peak | Winter super off-peak | Best for |
|---|---|---|---|---|---|
| TOU-D-4-9PM | 59¢ (4 to 9 PM) | 33¢ | 50¢ | 32¢ (8 AM to 4 PM) | Most homes, solar-only systems |
| TOU-D-5-8PM | 72¢ (5 to 8 PM) | 34¢ | 55¢ | 32¢ (8 AM to 5 PM) | Homes with a battery that covers the short peak |
| TOU-D-PRIME | 61¢ (4 to 9 PM) | 26¢ | 45¢ | 24¢ (8 AM to 4 PM) | EV, heat pump or battery homes with high usage |
Source: SCE Time-of-Use residential rate plans. Summer is June to September; winter is October to May. Rates shown are SCE-bundled. Simi Valley is in SCE Baseline Region 9, which earns a credit of about 9 cents per kWh on the first 16.9 kWh per day in summer on the two non-PRIME plans.
Two Simi Valley details change these numbers slightly. First, the city is a Clean Power Alliance member, so your generation charge comes from CPA. On TOU-D-4-9PM at 522 kWh a month, CPA’s Lean Power tier came to $190.49 versus $194.39 on SCE bundled service, about 2% less, per CPA’s July 2026 joint rate comparison. Second, every SCE customer now pays a $24.15 monthly Base Services Charge that solar cannot offset.
Simi Valley summers are the real story. Homeowners requesting solar quotes in the city average about 946 kWh a month, according to EnergySage, well above the California average, because inland afternoons push air conditioning hard right into the 4 to 9 PM peak.
How much do solar panels cost in Simi Valley?
Solar in Simi Valley costs about $2.49 per watt before incentives in October 2026. The average quoted system is 7.56 kW at about $18,842, with most quotes between $16,016 and $21,668, according to EnergySage’s Simi Valley data. A 13 kWh battery adds about $13,385 on average.
What pushes a Simi Valley quote higher: concrete tile roofs in Wood Ranch and newer tracts (extra labor for tile hooks and broken-tile replacement), a main panel upgrade on a 100 or 125 amp 1960s or 1970s home, multiple small roof planes that need microinverters, and a battery sized for whole-home backup.
Is there still a solar tax credit in 2026?
No, not for homeowners who buy. The 30% federal Section 25D credit does not apply to systems whose installation was completed after December 31, 2025, per the IRS guidance on the One Big Beautiful Bill Act. Leases and PPAs are different: the company that owns the system can still claim the Section 48E business credit on projects that meet the start-of-construction rules, and good lease offers pass part of that value to you. Our federal solar tax credit update covers the details.
The SGIP battery rebate is also mostly closed for SCE customers as of October 2026. The general residential budget and the equity resiliency budget both show closed on the SGIP program metrics page.
The one deadline that still matters is local to California. The state’s solar property tax exclusion becomes inoperative for systems completed after December 31, 2026, and the bill that would have extended it (AB 2389) stalled in May 2026. Without the exclusion, a new system can raise your assessed value. Simi Valley’s same-day SolarAPP+ permits make a December finish realistic, but only if you sign soon. Our property tax exclusion guide explains the math.
How long does solar take to pay off in Simi Valley?
A solar-only system in Simi Valley pays off in about 10 years in our model, and adding a battery to a larger system brings that to about 7.6 years. The difference is NEM 3.0: SCE now credits exported solar at roughly 5 cents per kWh, while the power you avoid buying at 4 to 9 PM costs 50 to 59 cents.
Simi Valley solar payback at October 2026 SCE rates (purchased system, no federal credit)
| System | Est. annual production | Installed price | First-year bill savings | Simple payback |
|---|---|---|---|---|
| 6 kW, solar only | 9,300 kWh | $15,000 | $1,507 | 10.0 years |
| 8 kW, solar only | 12,400 kWh | $20,000 | $2,009 | 10.0 years |
| 10 kW + 13.5 kWh battery | 15,500 kWh | $38,400 | $5,033 | 7.6 years |
Assumptions, so you can rerun this with your own quote:
- Production: 1,550 kWh per kW per year. NREL PVWatts gives 1,712 for an ideal south-facing roof in Simi Valley; we took about 10% off for real orientations and shading.
- Price: $2.50 per watt for solar, plus $13,400 for the battery, in line with EnergySage’s October 2026 Simi Valley averages.
- Solar only: 40% of production used in the home at 33 cents per kWh (summer off-peak and winter super off-peak), 60% exported at about 5 cents.
- Solar + battery: 50% used directly at 33 cents, 4,400 kWh a year shifted by the battery into the 4 to 9 PM window at a blended 53 cents, the rest exported at 5 cents.
- Not included: future rate increases (SCE’s average rate is up 56% since January 2021 per the CPUC Public Advocates Office), CPA’s 10% higher surplus credit, and the $24.15 fixed charge, which you pay either way.
The takeaway: in Simi Valley, the battery is not the expensive add-on. It is the part that turns cheap midday solar into 53 to 59 cent peak power. A solar-only system still saves real money, but if your quote has no battery and you use most of your power after 4 PM, ask why. Our NEM 3.0 explainer and true-up bill guide go deeper on export credits.
Do you need a battery in Simi Valley for power shutoffs?
If you live near the Simi Hills or the north and south edges of the city, a battery is worth serious thought. SCE can de-energize Simi Valley circuits under Public Safety Power Shutoffs during Santa Ana wind events, and in January 2025 about 52,000 Ventura County SCE customers were told to expect possible shutoffs. A standard grid-tied solar system shuts off during an outage for line-worker safety, so panels alone will not keep your lights on.
The good news: there have been no PSPS events in Simi Valley so far in 2026, and SCE reports 105 miles of covered conductor installed in the city with 35 more planned, according to Simi Valley Neighborhood Council minutes from May 2026. The risk is lower than it was in 2019, not gone. You can check which circuits are affected on the city’s PSPS page.
A single 13.5 kWh Tesla Powerwall 3 runs a refrigerator, lights, Wi-Fi and a gas furnace fan for about a day. Two units, or an Enphase or FranklinWH system sized at 25 to 30 kWh, can carry a central air conditioner for part of a hot afternoon. See our home battery backup guide and Powerwall 3 cost breakdown for sizing, or our backup battery page.
How long does it take to get solar permitted and turned on in Simi Valley?
In Simi Valley a standard rooftop system can be permitted the same day and turned on within a few weeks of install. Here is how the process works in 2026:
- SolarAPP+ approval. Your installer submits the design to SolarAPP+, which checks code compliance automatically. The admin fee is $25.
- City permit. The installer uploads the SolarAPP+ approval to the city’s online portal, and the permit is issued and emailed automatically. One combination permit covers the panels, a paired battery and a main panel upgrade.
- Install. Most residential installs take 1 to 3 days on the roof.
- One inspection. Requested online; requests made by 4 PM can usually be scheduled the next business day.
- SCE Permission to Operate. SCE targets 10 business days after a complete interconnection package for standard systems. Battery systems can take longer.
Ground mounts and additions to an existing system do not go through SolarAPP+; call Simi Valley Building & Safety at (805) 583-6723 first. If your HOA in Wood Ranch, Big Sky or another planned community requires approval, California Civil Code Section 714 gives the HOA 45 days to respond in writing, and it cannot impose rules that add more than $1,000 to your cost. See our California solar permit guide.
How do you choose a solar company in Simi Valley?
Pick the installer that designs for NEM 3.0, shows a clean license and puts the roof question on the table first. Five checks take about 15 minutes:
- Look up the license on CSLB. Confirm it is active, check workers’ compensation status and read any disclosable actions.
- Ask for a 4 to 9 PM plan. A good Simi Valley proposal shows how much of your evening usage the system covers, not just annual kWh offset.
- Get a roof answer in writing. If your roof is more than 15 years old, ask whether the installer recommends replacing it first and what removal and reinstall would cost later. Our removal and reinstall cost guide has the numbers.
- Check the tax credit line. Any purchase quote that subtracts a 30% federal credit in 2026 is wrong.
- Compare itemized quotes. Same panel, same inverter, same battery, then compare price. That is the comparison our price guarantee is built on.
Frequently asked questions
How much does solar cost in Simi Valley?
About $2.49 per watt before incentives in October 2026, or roughly $18,800 for a 7.5 kW system. Adding a 13 kWh battery brings a typical project to about $32,000. There is no federal tax credit for systems purchased and completed in 2026.
Is solar still worth it in Simi Valley under NEM 3.0?
Yes for most owner-occupied homes. Our model shows a 10-year payback for solar only and about 7.6 years for a 10 kW system with a battery at current SCE rates, before any future rate increases.
What utility serves Simi Valley?
Southern California Edison delivers power and sends the bill. Clean Power Alliance supplies the generation by default, on its Lean Power tier, unless you opted out to SCE.
How long does a solar permit take in Simi Valley?
A standard rooftop permit through SolarAPP+ is issued online, often the same day. The full process from signed contract to SCE Permission to Operate usually takes 4 to 8 weeks, with the install itself taking 1 to 3 days.
Who is the best solar company in Simi Valley?
We rank NRG Clean Power first for its price guarantee, in-house crews and Canoga Park office 15 miles away. Among companies based in Simi Valley itself, Next Door Home Upgrades and August Roofing & Solar have the strongest records.
Can I still get a solar rebate in Simi Valley?
Not much. The federal credit ended for purchased systems, and SCE’s SGIP battery budgets are closed as of October 2026. The biggest remaining benefit is the property tax exclusion, which applies only if your system is completed by December 31, 2026.
