Fast, Reliable Solar Battery Storage & Backup Across Allen
A solar battery install in Allen typically runs between $12,000 and $18,500 before incentives, and most homes we serve in 75002 and 75013 are up and running within two to three weeks of permit approval. That is the straight answer. What takes longer here isn’t the battery itself, it’s the Architectural Review Committee process that nearly every Allen HOA requires before you can put a battery on an exterior wall or run conduit across a side yard. We know those rules cold, we know the Allen permitting office turnaround times, and we have been quoting jobs in Twin Creeks, Watters Creek, Lovvorn Farm, and Cumberland Crossing long enough to tell you exactly what your HOA will and won’t approve before you spend a dime. Call (877) 550-6892 and we will walk your specific street and home layout over the phone.
Why Gus’s Solar Is Allen’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis founded this company in 2011 and put his own name on the truck. That matters in Allen more than most places, because this city runs on relationships and reputation. When a homeowner in Twin Creeks checks on a contractor, they ask neighbors. They ask the HOA manager. They ask the guy at the hardware store. Gus has been answering his own phone for 29 years in this metro, and the background-checked, uniformed crew that shows up at your door is his own crew, not a subcontractor handed a work order from a call center three states away.
Allen customers call us back because we do what we said we would. The 90-Day Done Right Promise is in writing on every battery job we do here: if it isn’t right, Gus comes back and makes it right. No argument, no ticket queue. One call, and he is the one who answers. For Allen specifically, our scheduling team coordinates from the Dallas-Fort Worth office and sends crews into Allen every weekday, often same-day for diagnostics when a homeowner reports a battery fault or a post-storm failure. A live person answers 24/7, so when a hail front rolls through at 2 a.m. and your system throws an error, you talk to a human, not a voicemail.
Our Solar Battery Storage & Backup Services in Allen
Some companies sell you a battery and walk away. We build a backup system that fits how Allen homes are actually built and how Allen HOAs actually rule. Here is what that looks like across the most common battery jobs we do in this city.
Tesla Powerwall Installation
A Tesla Powerwall 3 install in Allen lands between $14,000 and $18,500 for a single unit with the Gateway and a partial-home backup panel, depending on how far your main panel sits from the garage wall where the battery will live. Allen’s two-story brick homes with front-load garages usually put the battery on an interior garage wall, which keeps the HOA happy and shortens the conduit run to the main breaker. We stock Powerwall accessories in our Dallas-Fort Worth shop, so Allen installs rarely wait on parts.

Enphase IQ Battery Installation
Enphase IQ Battery 5P systems run $11,000 to $15,000 for a typical Allen retrofit, installed as an AC-coupled system that works with existing Enphase microinverters. That matters in Allen because so many of the 2000s-era homes already have Enphase IQ7 or IQ8 inverters on the roof, and pairing an IQ battery with that ecosystem is the cleanest path to whole-home backup. We reference the Enphase commissioning portal for Allen ZIP codes daily.

Whole-Home Backup Power
Whole-home backup in Allen means sizing a battery bank to carry two AC units, a pool pump, and a refrigerator through a summer hail-front outage or an Oncor rotating outage. For a 4,000 to 5,500 square foot Allen two-story, that is two Tesla Powerwalls or three Enphase IQ 5Ps, landing between $28,000 and $42,000 installed. The Allen wildcard is HOA conduit review: a smart install routes through the attic and down an interior chase rather than across a street-visible exterior wall, and we design that in from day one, not as a change order after the red tag.

Battery Retrofit for Existing Solar
Allen has a huge installed base of grid-tied solar from the 2015-2020 boom, when battery backup was a luxury. Homeowners who went solar then are now retrofitting batteries, and we handle about three of these a month in Allen. A typical retrofit in 75013 runs $13,000 to $19,000 depending on whether we can reuse the existing inverter or need to add a hybrid unit. The honest catch: some low-profile racking systems Allen HOAs forced years ago left no conduit pathway for battery expansion, so a retrofit may require soffit work or a new penetration. We quote that cost up front, not after you’ve committed.

Trusted Brands We Service in Allen
We install and service Tesla Powerwall, Enphase IQ batteries, and FranklinWH aGate and aPower systems across Allen, and we keep common diagnostic parts for all three in the Dallas-Fort Worth shop. When an Enphase IQ 5P in a Watters Creek home reports a thermal fault in August, our crew can often be there that day with the part on the truck. For Allen’s HOA-heavy installs, our internal wiring and flush-mount practices are built around Enphase and Tesla specs, because those two brands dominate the ARC-approved battery conversations in this city.
Common Solar Battery Storage & Backup Problems We See in Allen Homes
- HOA red-tag after rough-in: A battery placed on a street-visible exterior wall without ARC review gets flagged weeks after installation, forcing a relocation that adds drywall, stucco patch, and re-pulling conduit. In Allen, we file the ARC paperwork before we order equipment, not after.
- Dead array during outage: Owners in 75002 and 75013 who skipped battery backup discover their solar array can’t power the house when the grid drops. Oncor doesn’t care that you have panels if there’s no battery and no gateway, your refrigerator stays dark until the utility restores the line.
- No conduit pathway for expansion: Low-profile racking specs forced by Allen HOAs left many 2016-2020 solar installs with no spare conduit capacity. When homeowners want to add a battery today, some retrofits require soffit tear-out or a re-roof penetration to route the new circuits. We map this before we quote.
- Hail-impact stress on battery enclosures: Collin County sees golf-ball hail multiple times per decade, and exterior battery enclosures take direct hits. We inspect mounts and enclosures on every Allen service call and recommend impact-rated mounting locations for any outdoor install.

Our crews run Solar Battery Storage & Backup in Allen daily and serve the surrounding communities where the rules and housing stock differ enough to matter. Lucas and Fairview share Allen’s HOA density but often have larger lots and more tolerance for ground-mounted battery enclosures. Plano’s older, less HOA-saturated pockets move faster on permits. Murphy’s newer builds often have 2020-era panels that pair cleanly with Enphase retrofits. Each city plays by different rules, and we know which ones apply before we quote.

FAQs - Solar Battery Storage & Backup in Allen
Most Allen HOAs will approve an exterior battery mount only if it is not visible from the street and the conduit run is painted to match the wall. Texas Property Code §202.010 prevents an outright ban on solar devices, but Allen’s ARC committees routinely enforce placement and visibility rules, especially in Twin Creeks and Watters Creek. The safer play is an interior garage wall or a utility-closet install, which clears ARC review faster and avoids the red-tag risk. Call (877) 550-6892 and we will tell you what your specific HOA’s ARC guidelines say before you commit to a wall.
No, a hail strike to the battery enclosure does not void the manufacturer’s warranty, but cosmetic enclosure damage and mounting failure from a direct golf-ball impact are not covered under most standard warranty terms. Tesla, Enphase, and FranklinWH all require installation per their wind and impact mounting specs, which is why we install to IEC 61215 large-ball impact standards in Allen regardless of the brand. If a storm damages your battery mount, call us; we inspect and repair under our workmanship coverage.
Yes, depending on your Oncor plan and whether your municipality has adopted a retail-rate net metering structure. In Allen, most homeowners are on Oncor delivery with a retail electric provider of their choice, and some REPs offer free-nights or time-of-use plans where charging a battery from the grid between 9 p.m. and 6 a.m. is either free or deeply discounted. That math changes your whole battery sizing, because a battery that shifts your load off peak has a faster payback than one that only matters during outages. Bring us your utility bill and we will map it out.
Because Allen’s residential code enforcement follows the National Electrical Code, and NEC 2020 and 2023 require module-level rapid shutdown for rooftop PV even when microinverters are present. Microinverters shut down the DC side at the panel, but the battery and its AC wiring also need a rapid shutdown initiation device at the service disconnecting means. Practically, that means a system with battery backup needs a shutdown initiator mounted at the meter or main breaker, and it has to be accessible to Allen fire crews. We handle that in every install and sign off on the final inspection.
For a 4,000 to 5,000 square foot two-story in 75013 with two central AC units, you need at least 27 kWh of usable storage to ride out a four-hour outage with both condensers cycling, which translates to two Tesla Powerwalls, three Enphase IQ 10Ts, or one FranklinWH aPower plus an expansion module. If you only want to back up the downstairs unit, refrigerator, and a few lighting circuits, a single 13.5 kWh battery gets it done. We will look at your breaker panel and your actual AC tonnage before we recommend a size, because undersizing a backup system is the most common mistake we correct on Allen retrofits.
