AfterFast, Reliable Solar Battery Storage & Backup Across Clearlake
A solar battery for a Clearlake home typically costs between $11,500 and $18,500 installed, with whole-home backup systems running $22,000 to $38,000 depending on the battery count and whether the home is a manufactured unit that needs a ground-mount platform. Most Clearlake installs take one to two days, and our crews are here every week, not once a quarter. If your power is out right now or your inverter is throwing a fault code, call (877) 550-6892 and a live person picks up, day or night.
We work on Clearlake’s manufactured homes, mobile homes on permanent foundations, and the older wood-frame houses off Dam Road, Olympic Drive, and throughout the 95422 zip code. This is not a place where a stock rooftop battery mount always works. The housing here is different, the heat here is different, and the math on your PG&E bill is different. We plan around all three.
Why Gus’s Solar Is Clearlake’s Preferred Solar Battery Storage & Backup Company
Gus Petrakis started this company in 2011 and put his name on the building, the trucks, and the work. He is the one who answers when you call after hours, not a call center three states away. When a Clearlake homeowner calls about a battery that stopped charging or a backup circuit that did not switch over during a brownout, we treat it like it is our own power that went out. Because it might be, next week.
Clearlake homeowners have been burned by out-of-town solar companies before. A national outfit quotes one number on the phone, another at the door, and then a subcontracted crew shows up with no idea how a manufactured home chassis handles a wall-mount inverter. That does not happen with us. Gus’s crew does the install. Background-checked, uniformed, and trained on the exact housing stock Clearlake actually has. We do not hand the work off.
We answer the phone 24/7 with a live person, and our response time to Clearlake for emergencies is same-day in most cases. The 90-Day Done Right Promise is in writing on every battery job: if it is not right, Gus comes back and makes it right. One call. That is the whole warranty process.
Our Solar Battery Storage & Backup Services in Clearlake
Every battery job in Clearlake starts the same way: we look at your actual PG&E bill, your CARE status if applicable, your roof or ground space, and the real year-25 output math before we quote anything. Bring me a bill, I’ll bring you the math. That is how we work here.
Tesla Powerwall Installation
A Tesla Powerwall 3 installed in Clearlake runs $12,500 to $16,500 after the federal tax credit, including the gateway, permit, and labor. For manufactured homes off Dam Road or in the Highlands, we typically spec a ballasted ground platform instead of a wall mount, because a Powerwall weighs over 250 pounds and the interior wall framing in a 1970s double-wide was never built for that load. The system still backs up your essential circuits the same way.
Enphase IQ Battery Installation
Enphase IQ Battery 5P systems are a good fit for Clearlake because the modular design lets us install smaller 5 kWh units in multiple locations. That matters on older wood-frame homes where we want to keep the battery close to the subpanel and avoid a 40-foot conduit run across the side of the house. A single 5P with an Enphase system controller runs about $9,800 to $13,000 in Clearlake, and pairs cleanly with existing Enphase microinverter arrays.
Whole-Home Backup Power
Whole-home backup in Clearlake means sizing for a well pump, refrigerator, medical equipment if present, and lighting circuits during a PG&E Public Safety Power Shutoff. Clear Lake is not the coast, but interior Lake County still gets heat waves that strain the grid, and winter storms can knock out lines for hours. A two-battery whole-home system that covers the full main panel runs $22,000 to $38,000 depending on the home and the panel configuration. In manufactured homes, the transfer switch must be mounted on a backplate tied to the frame rails, not screwed into wall paneling. Too many crews skip that and bow the wall on day one.
Battery Retrofit for Existing Solar
Clearlake has hundreds of homes with solar panels that were installed before NEM 3.0 changed the export math. If you have an older grid-tied system and you are now getting pennies for what you send back to PG&E, a battery retrofit is the way to fix that. Retrofitting a FranklinWH aGate or Tesla Powerwall onto an existing array in Clearlake runs $11,000 to $15,500 after the tax credit, and it usually requires an updated line diagram and a new interconnection application, which we handle. We also check the condition of the original roof penetrations because on older Clearlake homes, that 2012-era racking may be the weak point.

Trusted Brands We Service in Clearlake
We install and service batteries from Tesla, Enphase, and FranklinWH, and we stock common components in our service vehicles so a Clearlake call does not wait three weeks on a backordered part. If you have existing solar from Panasonic, Canadian Solar, or JinkoSolar panels, the battery side still integrates cleanly with Enphase or Tesla hardware. We do not push one brand. We size the battery to your bill, your outage history, and your home’s physical reality.
Common Solar Battery Storage & Backup Problems We See in Clearlake Homes
- Inverter thermal throttling on 95°F+ summer days. Clearlake sits inland, east of Clear Lake, and regularly hits triple-digit temperatures from June through September. Inverters mounted on west-facing walls or in tight utility closets derate to protect themselves, which means your battery charges slower than the spec sheet promises. We mount inverters in shaded, ventilated locations or add active venting when the wall is unavoidable.
- Care-discounted consumption throws off the savings math. Many Clearlake residents receive PG&E’s CARE low-income rate, which lowers the baseline cost of the power a battery can offset. A contractor who ignores that will show you a payback period that has no relationship to reality. We calculate off your actual CARE-tier bill, not a generic PG&E residential rate table.
- Thin 1960s-1980s roof sheathing fails a structural review. Standard lag-into-rafter battery and inverter mounts on a roof need solid, code-compliant sheathing. Half-inch plywood from the 1970s, which is common in Clearlake’s smaller wood-frame homes, often does not pass. We catch this during the site assessment and move the equipment to a non-penetrating ground mount instead of forcing it.
- Salt-air corrosion from Clear Lake attacks mounting hardware and enclosures. Clear Lake is a natural freshwater lake, but the evaporative mineral content in the air close to the shore, especially around the docks and the lower streets near the lake, accelerates corrosion on untreated steel. We specify galvanized and powder-coated racking, stainless fasteners, and sealed conduit fittings on battery jobs near the shoreline.

FAQs - Solar Battery Storage & Backup in Clearlake
Yes, and we do these installs regularly in Clearlake. The key difference is that the battery and inverter usually go on a ballasted or non-penetrating ground-mount platform instead of a wall or roof mount, because the chassis and wall framing in a manufactured home are not built to carry that weight. We run a backplate to the frame rails for the transfer switch, which keeps the interior paneling from bowing. The backup capability is identical to a stick-built home. Call (877) 550-6892 and we will come out and look at your home specifically.
Yes, the mineral-laced air close to Clear Lake’s shoreline accelerates corrosion on untreated steel hardware, mounting brackets, and conduit fittings. We specify galvanized and powder-coated racking, stainless fasteners, and sealed enclosures on battery jobs within about a mile of the lake. On one 1978 double-wide off Dam Road, we replaced a corroded garage-door roller track and four rusted hinges before mounting a Tesla Powerwall on a ballasted ground platform, and we swapped in galvanized high-cycle springs and nylon rollers while rewiring the backup circuit to cover the well pump and refrigerator. The salt exposure had already pitted the old springs.
It depends entirely on your actual CARE-tier consumption and your solar array size, which is why we refuse to quote a battery in Clearlake without looking at the bill first. A CARE customer’s lower baseline rate means the battery offsets cheaper power than a non-CARE customer’s, so the payback period is longer and a naive estimate overstates the savings badly. For many CARE customers, the battery’s value is more about outage protection than bill savings. We model both and tell you the truth before you spend anything.
An east-facing array with afternoon shade still produces strong morning output, and under NEM 3.0 that morning production exports at a very low credit rate. A battery lets you store that morning generation and use it through the hot afternoon and evening, which is exactly when Clearlake’s inland heat drives your air conditioning load. The battery also gives you backup power during the PSPS events and storm outages that hit interior Lake County. We will model your actual production with shade factored in before recommending anything.
We mount inverters on shaded walls, add standoff brackets for air circulation, and when necessary install ventilation or relocate the unit to a cooler location like a north-facing wall or a garage with venting. Clearlake’s inland position means no coastal fog to cool the hardware, and a west-facing wall with direct afternoon sun can push an inverter to derate, which slows battery charging and clips output during exactly the hours you need it most. We plan for the heat, not around it. Free estimates include a full thermal site review.
