  We have not been paid by this company and the outstanding invoice is now more than 90 days delinquent. My solar company was contracted by Demo King Solar to perform a service call for one of their clients who was sold outside of the market they physically operate within (We are in Texas and they are in DC).

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

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

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.

• —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.
• —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.
