We researched all options before putting solar panels on our bungalow in Oak Park, so we were pretty confident when we selected Brighten Solar. Still, the level of care and service blew us away. Jeremy and Marine know their stuff; they are both personable and professional. And the installation was so easy, we hardly knew it happened. If it wasn’t for the fact that our electric bill fell into the basement, we wouldn’t know those panels were up there. Highly recommended.
