🌎🐾 Happy Earth Day!

We’ll be honest—this one snuck up on us a little! But the mission never changes: cleaner energy, a healthier planet, and a brighter future for the next generation (two-legged and four-legged alike 🐶).

Every solar panel installed is one more step toward reducing our footprint and protecting the place we all call home. And if our Huggy-logo could talk, we’re pretty sure he’d say: “More sun, less carbon… and maybe a treat.” ☀️🍃

If you’ve been thinking about going solar, today’s a great reminder—every day is Earth Day when you’re making smarter energy choices.

Let’s keep it simple, sustainable, and just a little bit fun.

We enjoy the hiking trails and the great things that does on the Southcoast of Massachusetts so we were really excited when asked if we would be interested in installing a 12KW system expansion designed and engineered by our friends
The cedar roof made for a challenging installation but our background in roofing enables us to take on these types of projects!

We had the pleasure of hosting code expert Matt Piantedosi to educate us on the 2026 National Electrical Code solar updates. We had a great mix of other local installers, building/electrical inspectors and fire department officials. It was a great day of learning spent with other folks committed to providing jobs built to the highest quality standards.

Multiple power outages and feet of snow! ☃️

We are getting calls already so if you are without power and worried about a snow covered array unable to charge your batteries give us a call now!!

We will be available late tomorrow and this week to clear snow off of arrays!! 💪

Solar + energy storage is an amazing combo… but if your panels get buried under snow while the power is out, and you don’t have an integrated generator, your battery may not be able to recharge. 🔋🚫

We’ll be out and on call to help clear off modules and keep your system running.

Don’t get left cold and in the dark — give us a call or text! 📞✨

It’s been a bit since we’ve done an employee spotlight and we’ve brought some more good people on so we’re going to get this going again! 💥

Meet Matt Cummings.
Matt’s been with us for over a year now and is now our lead licensed electrician. He came to us with years of electrical and solar specific experience. He quickly fit right into the Portside culture and we are so grateful to have him on our team.

He’s also one of Huggy’s favorites.🐶

Outside of work Matt enjoys riding his motorcycle, hiking with his dog and drawing.

We’re stoked you’re on board Matt, and looking forward to many more successful years with you! 👏

On Feb. 1, California’s batteries bridged the solar gap with seamless precision. After discharging through the night until sunrise, they spent the daylight hours charging, then pivoted back to exporting power well past midnight – effectively sustaining the state on solar energy for a full 24-hou...
