124 Contracts. Two Weeks. One Determined Team.

When the world shut down in 2020, we were gearing up for one of the biggest challenges in our history.

With battery storage demand skyrocketing, supply chain delays, and a small but dedicated crew, our worker-owners came together to make it happen.

Our latest blog takes you behind the scenes of the 2020 SGIP rush and shares how teamwork, adaptability, and a commitment to our community helped us navigate an unprecedented time.

Ever wonder what happens to the solar energy your home produces?

During the day, your panels generate electricity that can power your home. Depending on your system, excess energy may be sent to the grid or stored in a battery for later use.

Understanding where your energy goes is the first step toward getting more from your solar system.

When the power goes out, what do you want to keep running?

The refrigerator? Internet? Lights? Medical equipment? Heating or cooling?

Backup power isn’t necessarily about powering everything. It’s about identifying what matters most to your household and designing a solution around those priorities.

Let’s talk about what backup power could look like for your home.

Solar isn’t one-size-fits-all, especially in Northern California.

Your property, roof, energy use, utility rate plan, future electrification goals, and backup power needs can all influence what makes sense for your home.

That’s why we believe good solar starts with understanding the homeowner first.
Local knowledge. Thoughtful design. A system built for you.

There’s something different about working with people who live and work in the same community you do.

We’re a local cooperative focused on helping our neighbors make informed decisions about solar, battery storage, EV charging, and home energy.

No two homes are exactly alike, and we believe your energy solution should reflect that.

Local expertise. Community focused. Built for the long term.

Installing solar is only the beginning.

Your solar system is a long term investment in your home, and keeping an eye on its performance matters.

Monitoring and routine system checks can help identify production changes, equipment issues, and other problems that may otherwise go unnoticed.

Protect the system you invested in.

Your home’s energy needs probably won’t look the same five years from now.

Maybe an EV is in your future. Maybe you’re considering a heat pump, electric appliances, battery storage, or another home upgrade.

Thinking ahead when designing or upgrading your solar system can help prepare your home for what comes next.

Build for today. Plan for tomorrow.

You have solar. Do you need a battery too?

It depends on what you want your energy system to do.

Battery storage can help you use more of the energy your system produces, provide backup power during outages, and give you greater control over when you rely on the grid.

The right answer starts with your home, your energy use, and your goals.

Your electric bill shouldn’t be the only way you know how your solar system is performing.

System monitoring gives you a clearer view of production and can make it easier to recognize when something doesn’t look right.

A little more visibility can make a big difference when you own solar for the long haul.
