    I had an excellent experience consulting with John on evaluating a solar roof system for my home.

    John and his team are first rate. They focus on the entire customer experience, making sure solar is the right fit and address all the upfront and on-going considerations (tax credits, net-metering etc). Knowledgeable and customer-first team.

    John Marsiglia with Solar150 reached out to me about installing Solar on my home in Towson, MD. I have been very curious about going solar, as energy companies continually raise rates.

  • Better Business Bureau

    “have earned 5 star reviews and an A+ rating from the Better Business Bureau .”

Its website also mentions warranty and free estimate, but not in a sentence we can quote cleanly.

  • It posts on LinkedIn and Facebook. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Reisterstown is the area its listing was returned for, not an address we hold.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
