Solar, storage, and microgrid installation in Sausalito

Our office is on Bridgeway. Most of our team lives in Marin. We've installed solar on more Sausalito and Marin homes than almost any other engineering-led contractor in the area — and we're the only one whose CEO will pick up the phone if something goes wrong five years from now.

Why Sausalito properties make great solar candidates

Sausalito sits in a microclimate that is structurally better for solar than most of California gives it credit for. Marin's daytime fog burn-off lines up neatly with peak production hours, the hillside orientations on Bridgeway and through the canyons give plenty of south-facing roof exposure, and the building stock skews modern enough that structural retrofits are usually straightforward. The properties that pencil hardest are the ones you'd expect: hillside homes with backup-power needs and commercial buildings on the marina with strong daytime load profiles.

Marin's three solar-specific realities:
  • PSPS exposure. PG&E Public Safety Power Shutoffs hit Marin regularly during fire-weather windows. Battery storage isn't a luxury here — for hillside properties it's the difference between staying in your home during an event and not.
  • PG&E rate environment. Sausalito is on PG&E (not MCE — though MCE is the load-serving entity for many Marin customers). Residential rates run 30–45¢/kWh on average tiers. Solar economics here are stronger than the statewide average.
  • Marin County permit posture. Marin County's building department and the Sausalito building counter both have well-defined solar permit pathways. Average timeline from signed contract to permit issuance is 2–4 weeks — better than most Bay Area jurisdictions.

What we install in Sausalito

Residential Solar + Storage

Whole-home solar paired with batteries sized for PSPS and rate arbitrage. Maxeon, REC, Enphase, and Sol-Ark are our standard residential equipment.

Estate Microgrids

Multi-building properties where the main house, guest house, ADU, and pool house all need coordinated solar+storage. Off-grid-capable designs for hillside compounds.

EV Charging

Level 2 home charging paired with solar production schedules. Garage and motor-court installations coordinated with your electrician or contractor.

Commercial Rooftop

Marina-facing buildings and Bridgeway commercial properties. We design around your tariff, your tenant load, and your roof's actual structural capacity.

Local references

We've delivered systems across the Sausalito 94965 ZIP and broader southern Marin. A 122 San Carlos project in our case-study archive ran 2024 with full project P&L documentation. For broader portfolio examples, see our Pacific American Group case study (Hayward, replicable in Sausalito commercial properties) and our Airport Business Center portfolio (Sonoma County, 5-property model).

What our Sausalito clients ask most

How does the Marin fog affect production?

Less than people assume. Average annual solar irradiance in Sausalito is roughly 1,450 kWh/kW/year — only ~7% below sunnier Bay Area locations and well within the band where commercial and residential solar both pencil. We model your specific microclimate before we propose a system size.

Can we install on hillside or stilt-built homes?

Yes — that's a significant share of what we do in Marin. Hillside structural assessments and engineering get rolled into the design phase, and we coordinate with structural engineers (your own or one of our standard partners) when needed.

How long is a typical Sausalito install?

From signed contract to PTO (Permission To Operate): 8–14 weeks for residential, 4–9 months for commercial. Sausalito permit timelines are favorable; PG&E Rule 21 interconnection has been the variable in 2025–26.
