Fast, Reliable Solar Battery Storage & Backup Across Redwood Shores
If you’re reading this, the power probably flickered during the last winter storm, or you got your first true-up bill under NEM 3.0 and realized the math changed. In Redwood Shores, a battery backup system turns your rooftop solar into power you can actually use when the grid goes down or when PG&E rates spike at 7 p.m. A whole-home battery install in the 94065 zip code typically runs $14,000-$22,000 after incentives, and most jobs take one to two days once the equipment arrives.
We’ve worked on homes along Bridge Parkway, out near the lagoon, and through the townhome clusters off Marine Parkway. We know the HOA approval process here, and we know the salt air that comes off San Francisco Bay does a number on equipment that wasn’t specced for it. If you want a straight answer about whether a Tesla Powerwall or an Enphase IQ Battery makes sense for your specific house, call us at (877) 550-6892. A live person answers, day or night.
Why Gus’s Solar Is Redwood Shores’s Preferred Solar Battery Storage & Backup Company
Gus’s Solar is owned and operated by Gus Petrakis, who has put his own name on the building since 2011. That matters here more than most places, because Redwood Shores isn’t a town where you trust just anyone on your property. It’s a master-planned community where neighbors talk, where HOA boards communicate, and where a bad install on one roofline gets seen by forty people every morning on their way to Oracle or Electronic Arts.
We answer our own phone. When you call (877) 550-6892, you get a person who can look at your file, tell you when Gus’s crew can be in Redwood Shores, and give you a real answer about pricing. No voicemail maze, no call center three states away. Our Redwood Shores customers tell us the same thing, that the estimate we gave them on paper matched the final invoice, and that when something needed follow-up, the same crew came back, not a sub we’d never met.
We work on Tesla Powerwall, Enphase, Panasonic, and FranklinWH systems. We keep common components staged locally so a Redwood Shores service call doesn’t sit waiting on a part that has to ship from Texas. And every job includes the 90-Day Done Right Promise in writing: if it’s not right, Gus makes it right.
Our Solar Battery Storage & Backup Services in Redwood Shores
Tesla Powerwall Installation
A Tesla Powerwall 3 installed in Redwood Shores runs $11,500-$15,000 per unit including gateway, labor, and permits. For most homes here, one Powerwall covers essential circuits, two gives you genuine whole-home backup. The salt-mist exposure off the bay means we make sure all exterior conduit and connectors are marine-rated, something a crew from inland San Jose might not think twice about.

Enphase IQ Battery Installation
The Enphase IQ Battery 5P is modular, which suits Redwood Shores townhomes and condos where wall space matters. A typical install lands around $9,000-$13,000 for the first unit, less per unit when you stack multiples. We see a lot of homes along the lagoon side choosing Enphase because the hardware footprint is smaller than a Powerwall and it integrates cleanly with existing Enphase microinverter systems.

Whole-Home Backup Power
If you want the furnace, the refrigerator, the internet, and the lights to all keep running during an outage, that’s a whole-home backup configuration. In Redwood Shores, where many properties back up to water and the evening wind can take down lines, this usually means two batteries plus a smart load panel, landing around $24,000-$34,000. We sit down with your actual PG&E usage data before quoting anything, so you’re not paying for capacity you don’t need.

Battery Retrofit for Existing Solar
Plenty of Redwood Shores homes installed solar years ago, back when NEM 2.0 meant selling excess power to the grid was actually worth it. If your system needs attention, we also handle Redwood Shores Solar Panel Repair. Now that NEM 3.0 has cut export values, adding a battery is how you hold onto the power your panels already make. Retrofit pricing runs $12,000-$18,000 depending on your inverter setup and panel age, and it’s the single most common job we do in the 94065 zip code right now.

Common Solar Battery Storage & Backup Problems We See in Redwood Shores Homes
- Salt-air corrosion on battery enclosures and conduit. Persistent west wind off San Francisco Bay carries fine salt mist. We regularly replace corroded connectors and corroded conduit on Redwood Shores installs that a generic contractor, not a local one, put in five years ago and hasn’t looked at since.
- HOA compliance failures that stop a battery retrofit cold. Nearly every home in Redwood Shores sits inside an HOA that has an architectural review process. We’ve seen systems ordered and then denied because the placement didn’t meet shoreline-community guidelines. Our Redwood Shores experience means we help you pre-flight the HOA packet before you spend a dollar.
- Incorrect system sizing due to the marine layer. Contractors calibrated for San Carlos or Belmont underestimate how much the afternoon fog off the bay cuts production. A correctly sized battery for Redwood Shores needs local PVWatts inputs, not default ZIP code data.
- Existing solar inverters that won’t talk to new battery hardware. Homes built during the 1990s and 2000s construction phases often have older string inverters that need a communication bridge or a full inverter swap before a battery can be added. We handle that in-house rather than leaving you with two systems that don’t coordinate.
Pricing for Solar Battery Storage & Backup in Redwood Shores, CA
Here’s the honest math. A single Tesla Powerwall 3 installed in Redwood Shores: $11,500-$15,000. An Enphase IQ Battery 5P: $9,000-$13,000 for the first unit. A retrofit onto existing solar with one battery: $12,000-$18,000 out the door. Whole-home backup with two batteries and a smart panel: $24,000-$34,000. These numbers include permits, labor, and the Federal Investment Tax Credit where applicable. They do not include any Redwood Shores HOA-specific engineering documents, which some associations require and typically add $300-$900.
What actually moves the price in Redwood Shores is your existing inverter, the age of your panel, and whether your HOA wants architectural drawings. We quote from your actual PG&E bill, not a brochure, and the price we quote is the price you pay. Bring me a bill, I’ll bring you the math. Call (877) 550-6892 for a free estimate, and take two weeks to think about it. The price will be the same.
