Why Gus’s Solar Is Cotati’s Preferred EV Charger Installation Company
Gus’s Solar has been working in and around Cotati long enough to know the difference between a problem you can see and one hiding behind a 1970s electrical panel. We’re not a national outfit with a call center in another state. Gus Petrakis founded this company in 2011, publishes his name and license number, and answers his own phone. When you call (877) 550-6892, a live person picks up, not a voicemail tree.

We schedule most installs within two to three business days of your call, and we show up in uniform with background-checked techs.

What makes us different in Cotati: we don’t hand work off to subcontractors, we don’t pressure you to sign tonight, and we quote the year-25 number on solar-paired systems, not just the day-one brochure figure. Bring us a bill, and Gus will bring you the math.
Our EV Charger Installation Services in Cotati
Level 2 Charger Installation
A Level 2 charger turns a dead battery from an overnight worry into a two-to-four-hour errand. Most Cotati homes we visit in the older tract neighborhoods off School Street and West Sierra Avenue have either no dedicated 240V circuit or one that’s already shared. We run the circuit, mount the charger, and configure it for your panel’s actual capacity. In Cotati, a straightforward Level 2 install on a panel with spare capacity typically runs $650 to $900 before permits. If we need to pull a new circuit across an attached garage or through a crawlspace, budget $1,000 to $1,450.
Tesla Wall Connector Installation
We install more Tesla Wall Connectors in Cotati than any other single charger model. The unit itself is solid, and it pairs well with a solar setup when the placement is right. But we’ve seen too many Cotati installs where the connector went up on a garage wall facing the street, only to discover the roofline actually angles northeast once you put a compass on it. That’s the hexagonal street grid at work. For Tesla owners in Cotati, a Wall Connector install on an existing 240V line starts around $700. With a new circuit run, expect $1,100 to $1,750. We also configure the charger’s scheduling to draw power when your home actually has surplus, which matters here because the Petaluma Gap fog knocks out morning solar production for much of the summer.
Panel Upgrade for EV Charging
This is the job we end up doing most often in Cotati. The city’s housing stock was built largely between 1960 and 1985, and a lot of those homes still run on 100-amp panels. Add a Level 2 charger pulling 32 to 48 amps, run the AC, and switch on the dryer, and that main breaker trips. Not every home needs a full panel swap. We start with a load calculation off your actual usage, not a generic worksheet. If a panel upgrade is necessary, a 100-to-200-amp swap in a typical Cotati ranch or split-level runs $2,500 to $4,000, with permits and PG&E coordination included. We’ll tell you honestly if you can get by with a smart load managed charger instead, which often cuts the cost by half.
Garage & Driveway Charger Wiring
Whether your charger goes in the garage or out at the driveway’s edge, the wiring path matters more in Cotati than in neighboring cities. The angled lots here mean conduit runs often zigzag around corners that don’t align with any logical compass direction. We’ve fished wire through detached garages off Old Redwood Highway and run surface conduit along driveways in the neighborhoods east of the plaza. A garage install on an interior wall near the panel is the cheapest: $650 to $900 total. A driveway pedestal or detached garage run needs trenching and conduit, which lands between $1,200 and $2,100 in Cotati’s rocky, clay-heavy soil.

Common EV Charger Installation Problems We See in Cotati Homes
- Tripped main breakers from a missing load calculation. Older 1960s to 1980s panels in Cotati often have no spare capacity for a dedicated 240V circuit. A Level 2 charger wired without checking actual loads trips the main when the AC and dryer run at the same time. We run the numbers before we touch anything.
- Slower solar-paired charging on summer mornings. The Petaluma Gap’s marine layer sits over Cotati well into midday from June through August. Systems sized with generic Sonoma County irradiance data underproduce, leaving you with a partially charged EV by evening. We model your system on Cotati-specific sun data, not the county average.
- Roof problems hiding behind a charger install. Many Cotati homes still carry their original composition shingle roofs. Before we mount conduit or a paired solar array, we check the roof condition at every penetration point. Skipping this step means leaks, and leaks mean callbacks.
- Charger placement based on the wrong compass reading. Cotati’s hexagonal street grid means a house that looks south-facing from the street might actually face northeast. We’ve pulled out a compass on dozens of site walks and corrected charger and panel placement because of it. It’s a small thing that changes monthly charging output in a big way.

FAQs - EV Charger Installation in Cotati
That’s the Petaluma Gap fog. Cotati gets more overcast summer mornings than Santa Rosa just seven miles north, and if you’re charging off solar, the marine layer cuts morning production meaningfully. In winter and spring, afternoon skies clear and production actually beats summer mornings here, which is the reverse of most of Sonoma County. We size Cotati systems for this reversed seasonal curve so you’re not left with an empty battery on a foggy July morning. Call (877) 550-6892 and we’ll walk through your actual production numbers.
Sometimes, but not always. It depends on your existing loads and whether you add a smart load management device that tells the charger to back off when the AC or dryer kicks on. We’ve done plenty of Cotati installs on legacy 100-amp panels using load managed chargers, which cost $200 to $400 extra and avoid a $2,500 to $4,000 panel swap. But if your panel is already maxed out, we’ll tell you straight. Bring us a bill, we’ll bring you the math, and you can take two weeks to decide if you want to.
Yes, more than most people expect. The historic hexagonal plat radiating from the downtown plaza means street-facing orientation often doesn’t match true compass direction. A garage that looks south-facing from the curb can actually be angled northeast by 30 degrees or more. For solar-paired charging, that changes afternoon production enough to matter. We pull out a compass on every Cotati site walk and verify azimuth before we mount anything.
Yes, if you’re on PG&E’s net metering program and your system was sized with EV charging in mind. The catch in Cotati is that the Petaluma Gap’s fog curve means summer credits build slower than in Rohnert Park or Santa Rosa. If your current system was sized before you bought the EV, you may be pulling more from the grid than you expect, especially on gray summer mornings. We can run the numbers off your actual bill and tell you whether a system expansion or a battery makes sense before you spend anything. Free estimate, no signature wanted tonight.
Then we fix the roof first, or we coordinate with a roofer we trust before we mount anything. A lot of Cotati’s 1960s and 1970s composition shingle roofs are at or near the end of their service life. Mounting conduit or a solar array on a failing roof means leaks and expensive repairs later. We include a roof condition check in every solar-paired EV estimate, and we’ll tell you honestly if the roof needs to come first. If a roofer quotes you a number, bring it to us for a free second opinion.
