Our mission

Your purchase from Mars Solar is a lot like buying from your neighborhood corner store. Not only are you supporting our family, but you’re also supporting other, extraordinarily hard-working small businesses and their families...

Our products are designed and assembled in Colorado, USA. We pay our partners fair wages because we want them to feel secure and valued. And, for operations, we hire our family and friends.

Now, with all that said, if we are lucky enough to call you a customer, great. But, if for whatever reason you don’t see anything that catches your eye, please walk away with this…

I encourage you to leave the world better than you found it by thoughtfully choosing quality over quantity, less over more, lasting over “trending” and profound over popular.
