Founder & Owner
Meet Our Founder
Built on Honesty.
Driven by Results.
Freddy Petkus founded Critical Mass Solar after years as an educator and basketball coach — roles that taught him one thing above all else: people make better decisions when they're genuinely informed, not pressured.
That experience shaped everything about how Critical Mass Solar operates. Freddy holds a business degree and a Massachusetts Construction Supervisor License (CSL), and he built this company on a simple belief: homeowners and business owners deserve straight answers, honest numbers, and the space to decide for themselves.
"We Inform. You Decide." isn't a tagline. It's how every site assessment, every proposal, and every conversation is conducted. If solar doesn't make sense for your property, Freddy will tell you that too.
Our Philosophy
Why We Educate First
Solar is a significant investment. Before you commit, you deserve to understand exactly what you're getting — the real payback period, honest production estimates, the incentives that actually apply to your situation, and the questions you should be asking every installer you talk to.
We install residential, commercial, and agricultural solar across MA, NH and New England. Whatever your property type, we take the time to walk you through the numbers — no glossy brochures, no bait-and-switch financing. Just clear information so you can make the decision that's right for you.
Our Work
Real Installations. Real Results.
From residential rooftops and agricultural properties in Massachusetts to commercial arrays in New Hampshire, every Critical Mass Solar installation is designed for maximum performance and long-term reliability. We serve homeowners, businesses, and farms across MA, NH and New England — and we stand behind every project we complete.
