AfterFast, Reliable Commercial Solar Installation Across Los Alamitos
Commercial solar installation in Los Alamitos typically runs $2.35-$3.10 per watt before incentives, so a 50 kW rooftop array lands between $117,500 and $155,000. Most commercial projects we handle take 6-14 weeks from permit to power-on, though the JFTB airfield review can add a few weeks if your roof sits near the approach path. Call (877) 550-6892 and we’ll give you real numbers off your actual usage, not a brochure guess.
Gus’s Solar has worked inside Los Alamitos’s 90720 and 90721 ZIP codes for years, and we know the local permitting rhythm better than an out-of-town crew ever could. The Community Development counter reviews rooftop solar against a specific checklist, and near Katella Avenue that checklist changes. We handle it so you don’t have to.
Why Gus’s Solar Is Los Alamitos’s Preferred Commercial Solar Installation Company
Gus Petrakis started this company in 2011 and still answers his own phone. When a Los Alamitos business owner calls about a warehouse array or a carport, they talk to the person whose name is on the permit, not a call center three states away. That’s how we’ve built our reputation across Los Alamitos and the surrounding cities.
Our crew knows the Los Alamitos commercial building stock. The flat TPO roofs on industrial buildings along Cerritos Avenue, the older single-story retail near Los Alamitos Boulevard, the newer flex spaces by the 605. Each roof type changes the racking approach, the ballast plan, and the wire runs.
Gus’s crew does the install. Background-checked, uniformed, and trained on the specific brands we carry. No subcontracted labor, ever. When we say we’ll be at your Los Alamitos business on Tuesday, the same crew that quoted it is the crew that rolls up.
The 90-Day Done Right Promise applies to every commercial job. If something isn’t right after commissioning, Gus makes it right. In writing. One call brings him back.
Our Commercial Solar Installation Services in Los Alamitos
We handle the full scope of Commercial Solar Installation for Los Alamitos businesses, from a small office rooftop to a warehouse that runs three shifts.
Commercial Rooftop Solar
Most Los Alamitos commercial rooftops are either low-slope TPO on the industrial side or composition shingle on older retail buildings. TPO roofs need non-penetrating ballasted racking where possible, and we coordinate with your roofer to keep the warranty intact. On shingle roofs near the JFTB approach, we file the FAA paperwork and schedule the glare study before we touch a panel.
Commercial Battery Storage
Time-of-use rates from SCE mean a battery can pay for itself faster here than in a flat-rate market. Los Alamitos businesses with afternoon peaks benefit from shifting stored solar into the 4-9 PM window. We install Tesla Powerpack and FranklinWH commercial batteries, sized to your actual interval data, not a multiplier from your square footage.
Warehouse & Industrial Solar
Warehouse roofs along the Los Alamitos industrial corridors present the best per-watt economics of any commercial project. Big, open, low-slope roofs with minimal shading. We’ve handled arrays from 30 kW up to several hundred kW. The permitting step that catches most out-of-area installers is the FAA notification for anything near the JFTB runway line. We build that timeline into the contract from day one.
Solar Carport Installation
Carports make sense for Los Alamitos businesses that want canopy shade and production in the same footprint. They require structural engineering, deeper footings for the coastal soil conditions here, and sometimes a variance if your lot sits in a setback zone. We quote the engineered cost, not a ballpark figure that changes at the permit desk.
Commercial Solar Maintenance
Salt air off the Pacific at Seal Beach drifts inland 3-4 miles into Los Alamitos, and that salt settles on panels and racking. We recommend a spring and fall cleaning and hardware inspection for any commercial array here. Corroded fasteners, loose panel clips, and bird nesting under panels are the three things we fix most often on existing commercial systems in the 90720 ZIP.

Trusted Brands We Service in Los Alamitos
We stock Qcells, REC, and Panasonic panels at our Los Angeles warehouse and install them daily in Los Alamitos. For inverters, we work mostly with SolarEdge and Enphase. Power optimizers handle the morning June Gloom better than plain string inverters, especially on commercial roofs that don’t get full sun until 10 AM from late May through July. If you already have a system with SunPower or Canadian Solar, we service those too.
We keep common parts local so a Los Alamitos repair doesn’t wait on a slow freight delivery from the East Coast. Most maintenance visits here are same-week.
Common Commercial Solar Installation Problems We See in Los Alamitos
- FAA Form 7460-1 surprises. Rooftop solar within the JFTB notification radius triggers an FAA review and glare analysis before the city issues a permit. Out-of-area contractors often find this out at the permit counter, adding weeks to a project they promised would close in a month.
- Marine layer overproduction math. Sizing a Los Alamitos commercial array with generic Southern California irradiance data overstates production by 8-12% because June Gloom suppresses morning output from late May through July. We size with local TMY data from the Long Beach station, not a statewide average.
- Aging 100-amp service panels. Older commercial buildings from the 1950s through 1970s commonly carry 100-amp panels that SCE flags during interconnection review. You’ll need a 200-amp upgrade before net metering gets approved. We catch this in the site survey and fold the cost into the initial quote.
- TPO roof penetrations done wrong. Flat commercial roofs in Los Alamitos don’t forgive sloppy flashing. We use properly flashed mounts with manufacturer-rated seals, because a leak that starts on a TPO roof three years later is a lawsuit and a ruined customer relationship.

FAQs - Commercial Solar Installation in Los Alamitos
Only commercial rooftops and carports within the JFTB notification radius trigger FAA Form 7460-1. The city’s permit technicians flag projects near the runway approach path for FAA coordination review. Most of the industrial corridor along Katella Avenue falls within scope; the retail strip near Los Alamitos Boulevard at the northern edge of the 90720 ZIP usually does not. We check your parcel against the current FAA obstruction map during the free site survey and tell you before any contract is signed. Call (877) 550-6892 and we’ll run your address.
We use Local TMY irradiance data from the Long Beach station rather than generic Southern California averages. June Gloom suppresses morning production from late May through July, cutting 8-12% off what a generic model would predict. We also pair the array with power optimizers so each panel runs independently when one string sits in shade from a neighboring structure or the Catalina Eddy cloud deck. Gus quotes the year-25 output, not the day-one brochure number.
No, not in most cases. SCE’s interconnection review looks at your service panel capacity regardless of inverter type. A 100-amp panel on a 1950s-1970s commercial building in the 90720 ZIP frequently fails that review for any solar system above roughly 10 kW. You’ll need a 200-amp upgrade before SCE approves net metering. We catch this in the initial survey so the upgrade cost is in your first quote, not a mid-project surprise. Call (877) 550-6892 for a site visit; estimates are free.
A glare study models how much sunlight your panels will reflect toward aircraft on approach and toward the JFTB control tower. The engineering firm runs a geometric solar position analysis for every hour of daylight across a full year and checks the results against FAA glare thresholds. If any angle exceeds the limit, the FAA can require panel tilting, repositioning, or anti-reflective glass coatings. We scheduled one for a commercial rooftop near Katella Avenue in 90720 and filed it with the permit package, which kept the city and the FAA moving in parallel instead of sequentially.
No. All three cities fall under Southern California Edison, but the net metering program is now NEM 3.0 for new commercial applications, and export credits are tied to avoided-cost rates that shift by time of day. Los Alamitos sits in the same SCE rate territory as Seal Beach and Long Beach, so the rate structure is identical. What changes is the production profile: Los Alamitos sits slightly inland from Seal Beach, so the marine layer burns off 30-60 minutes earlier here, which shifts some production into higher-value midday hours. That’s a real marginal advantage. Call (877) 550-6892 and bring your last 12 months of SCE bills; we’ll run the exact offset and payback for your load profile.
