Your electricity needs are increasing

Over the next decade you’ll add an EV charger, swap the furnace and water heater for heat pumps, and replace the gas range with induction. Every one of those decisions runs through your electrical panel, and increases your reliance on the grid.

PG&E is not able to deliver.

What most installers get wrong.

They sell solar and batteries. They don’t consider your home as one connected energy system.

Four things that make a Potrero system different.

Every design decision is made to lower your cost over the long run.

Same upfront price as the typical Bay Area quote. Roughly double the value over the long run.

They were very straightforward - clear communication from start to finish, no surprises, install team was awesome and the product works great. The price was much less expensive than other quotes I got for solar and batteries.

Production is right where they said it would be, and we've already had a PG&E power outage where the whole-home battery backup worked flawlessly.

One project. One engineer. Start to finish.

The person who designs your system signs off on the final install. No call-center handoff, no salesperson disappearing after you sign. The first conversation is a design consultation with the engineer who would run your project.

The questions we get from buyers who are paying attention.

Same price. Twice the value.

A 30-minute design consultation, with the engineer who would run your project. We’ll bring the conservative case and a fixed price. If it doesn’t pencil for your house, we’ll say so.
