Fast, 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.

Call (877) 550-6892

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.

Pricing for Solar Battery Storage & Backup in Clearlake, CA

Here is what Clearlake homeowners should expect to pay, before the 30% federal tax credit, for the battery work we do most often:

  • Tesla Powerwall 3 single-battery install: $14,500 - $17,500
  • Enphase IQ Battery 5P single-unit install: $10,500 - $13,000
  • FranklinWH aGate + aPower pair: $18,000 - $24,000
  • Whole-home backup, two or more batteries: $22,000 - $38,000
  • Battery retrofit to existing solar (NEM 2.0 system): $11,000 - $15,500
  • Battery expansion, adding a second unit to an existing system: $9,500 - $13,000

Ground-mount ballasted platforms, common for Clearlake’s manufactured homes, add $1,800 to $3,500 depending on the site. Structural assessments run $250 to $500 when a roof-mount is being evaluated. Estimates are free, the number is the number, and you should take two weeks to think about it. The price will be the same.

What San Jose Customers Say

Trusted by homeowners across San Jose and surrounding areas.

★★★★★

"He modelled it on my actual bill and the current export rates rather than the old ones, and told me plainly that the payback was longer than the door knockers had claimed. Then it came in about where he said it would."

Octavius Redmond · Verified customer
★★★★★

"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."

Sunita Balakrishnan · Verified customer
★★★★★

"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
