Fast, Reliable Solar Battery Storage & Backup Across Paramount
When the power kicks off in Paramount, most folks find out the hard way that their rooftop solar shuts down with it. Grid-tied inverters are designed to cut out during outages for utility worker safety, which means those panels on your roof do nothing for you the moment SCE goes dark. A home battery changes that. Solar battery storage in Paramount typically runs $13,500 to $19,500 installed after the federal tax credit, and a well-sized system keeps your refrigerator, lights, internet, and medical equipment running through most outages without you lifting a finger.
We’re Gus’s Solar, and we’ve been putting batteries on Paramount homes long enough to know the streets from Garfield Avenue to the neighborhoods tucked west of the 710. If you want a straight answer about what battery backup will actually cost on your house, call (877) 550-6892. A live person answers.
Why Gus’s Solar Is Paramount’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 and never handed the keys to a private equity firm or an out-of-state call center. When you call about a battery install in Paramount, you’re calling the owner’s own shop. Gus’s crew does every install. Nobody is subcontracted, and nobody is knocking doors with a laminated badge claiming to be “with the utility.”
We’ve worked on homes across the 90723 zip code, from the modest postwar bungalows near Paramount Boulevard to the cul-de-sac streets east of Downey Avenue. Homeowners in Paramount tell us the same thing after other companies have come through: the quote changed at the door, the salesman needed a signature that night, and the phone number stopped working the week after. We don’t do any of that. Bring us a bill, we’ll bring you the math. Take two weeks to think about it. The price will be the same.
Gus’s crew shows up in uniforms, background-checked, with the owner’s name on the truck. We’re part of Paramount‘s working neighborhood, not a pop-up sales crew running a short-term blitz out of a rented conference room. If something isn’t right, one call brings Gus back. That’s the 90-Day Done Right Promise, in writing, on every job.
Our Solar Battery Storage & Backup Services in Paramount
Tesla Powerwall Installation
The Powerwall 3 is the battery we install most often in Paramount. It’s a compact unit that mounts on a garage wall or exterior side yard, and it pairs cleanly with homes that already have or are adding solar. For a typical Paramount ranch home with a 100-amp panel, one Powerwall usually covers the essentials during a blackout: fridge, a few lights, the Wi-Fi, and a gas furnace blower. We quote the year-25 output, not the day-one brochure number.

Enphase IQ Battery Installation
If your existing system is Enphase microinverters, the IQ Battery 5P is often the simplest retrofit. It integrates natively with Enphase monitoring so you see solar production and battery state in one app. Homes in Paramount west of the 710 tend to accumulate faster panel soiling from the freight corridor, and Enphase’s per-panel monitoring makes it easier to spot a panel that’s underperforming before it drags down your whole array. We also handle Solar Panel Cleaning in Paramount when that diesel film gets too thick.

Whole-Home Backup Power
Whole-home backup means the battery is sized and wired to carry every circuit in the house, including the air conditioner. That takes a larger battery bank than most folks expect, especially with Paramount’s summer heat. We’ll walk you through exactly what a full-home setup looks like on your actual utility bill usage, not a generic estimate. If a salesman needs an answer tonight, the answer is no.

Battery Retrofit for Existing Solar
Most Paramount homeowners who call us already have solar and want to add storage after NEM 3.0 cut their export credit, sometimes after realizing they need Paramount Solar Panel Repair first. The retrofit usually involves adding a battery, a new inverter or a hybrid inverter, and some rewiring at the main panel. On older Paramount homes with original 100-amp service, we’ll often recommend a panel upgrade to 200 amps at the same time so you don’t have to open up the wall twice. That cost gets quoted upfront, never as a surprise change order.

Trusted Brands We Service in Paramount
We install and service batteries from Tesla, Enphase, SolarEdge, and FranklinWH, plus solar panels from Qcells, Panasonic, and REC, and we handle Solar Panel Maintenance & Monitoring in Paramount too. For Paramount customers, that matters because we keep common parts and firmware knowledge local, not “eligible for warranty review.” If a Powerwall throws an error code or a FranklinWH aGate needs a replacement power module, we can usually be on site fast. You won’t wait two weeks for a remote diagnostic with someone reading a script in another time zone.
Common Solar Battery Storage & Backup Problems We See in Paramount Homes
- Battery undersized for actual nighttime usage. A single 13.5 kWh battery sounds like a lot until a family runs the AC, a pool pump, and a second fridge overnight. We always size against your real kilowatt-hour history from your bill, not a square-foot average.
- Existing solar doesn’t charge the battery during a grid outage. Many older grid-tied systems need a hybrid inverter or a backup gateway added. Without it, the battery sits at 20% while your panels produce nothing usable. This is one of the most common callouts we get in Paramount.
- Diesel soot and dust choking off panel output. Homes west of the 710 facing east catch a steady load of freeway particulate that cuts solar production faster than the sun-hours math would predict. A battery can’t charge what dirty panels don’t produce. We flag this on every Paramount site visit.
- Original 100-amp panels limiting what a battery can back up. Paramount’s housing stock from the 1950s and 1960s frequently has original or early-replacement 100-amp service. A whole-home backup almost always needs a 200-amp upgrade first, and we quote that as part of the job from day one.
Pricing for Solar Battery Storage & Backup in Paramount, CA
A single Tesla Powerwall 3 or Enphase IQ 5P installed in Paramount typically runs $13,500 to $16,500 before incentives. A FranklinWH aPower system with the aGate controller usually lands between $14,000 and $18,000 depending on whether you’re adding whole-home backup circuits. Battery retrofits to existing solar fall in the $9,000 to $13,000 range for the battery and controls, with a 200-amp panel upgrade adding another $3,200 to $4,800 when the house still has the original 100-amp service. The federal tax credit knocks 30% off the total. Senior and Veteran customers get 10% off, and that never expires. We don’t charge a trip fee for homes inside our own county, so an estimate in Paramount is free. Call (877) 550-6892 and we’ll give you a number off your actual bill.

FAQs - Solar Battery Storage & Backup in Paramount
For most Paramount homes, we can schedule an estimate within a few days and complete a standard single-battery install within two to three weeks of permitting. Emergency service calls for existing customers are handled as fast as we can get a truck to your street. Call (877) 550-6892 and a live person will tell you the soonest we can be there. No voicemail, no ticketing portal.
Yes. We work across the entire 90723 zip code, from the streets west of the 710 near the freight corridor to the residential blocks around Paramount High School and the neighborhoods bordering Downey and Bellflower. There’s no part of Paramount we won’t come to for an estimate, and no trip charge inside our county.
If it’s an emergency where your existing battery has failed and you’re without backup power, we’ll get someone out as fast as our schedule physically allows. Most outages in Paramount are handled same-day or next-day for existing customers. For new installs, same-day isn’t honest; the equipment often needs to be ordered for your specific panel configuration. We’ll give you a real timeline when you call.
No. The equipment cost is identical and our labor rate doesn’t change across neighboring cities. The only Paramount-specific cost factor is the higher likelihood of a 200-amp panel upgrade on older postwar homes, which adds $3,200 to $4,800 when needed. That’s a house-age issue, not a city-pricing issue. Estimates are free and the number we quote is the number you pay.
You get the manufacturer’s warranty on the equipment, which is typically 10 years for Tesla, Enphase, and FranklinWH batteries, plus our 90-Day Done Right Promise on the installation itself. If something isn’t right, Gus makes it right. No fine print, no “that’s normal.” Call (877) 550-6892 for specifics on the equipment you’re considering.
