  Well, Luminalt just finished installing a 5.25kW system on my roof. They have been super easy to work with, everything happened as they said they would, very straightforward team, great work, easy process etc. Highly recommend them!

  One of the very best contractors we've ever dealt with. The whole company has amazing customer service, from the guy who came out to discuss all of the options available (he worked up several different detailed proposals so we could make an informed decision), to the office staff who scheduled meetings and installation dates. The crew that did the installation was friendly and punctual, and got the whole job done in a couple of days. The founder of the company came out to meet with the city inspectors. He has been working in solar and alternative energy all over the world since the '80s, and has a wealth of knowledge and experience. Can't recommend them highly enough. They deserve all of their five star reviews.

  I had started down the solar road with one of the big companies that does a lot of promotion. They didn't do anything 'wrong', per se, but there was so much hype and constant selling that it made me nervous. Then I compared their reviews to Luminalts and had the Luminalt people give me a quote. They were a little more expensive, but for an investment of this kind over many years it seemed a small amount of money compared to feeling like I was getting straight answers. I just threw the switch on my new solar setup yesterday and every step of the way with Luminalt was a pleasure--they are very direct, on time, competent and all those good things. All thumbs and fingers up!

  Luminalt has installed 5 solar photovoltaic systems on 3 of my San Francisco apartment buildings. I am now supplying "house" electric for 45 apartments. The installs were terrific - from meeting with Nelson to plan and cost to dealing with each of the installs. The technicians were excellent and did what they said when they said and cleaned up after. There were no complaints from any of my tenants and they like living in a "green" building that also has thermal hot water. I have the upmost respect for the company and the bonus is that they are a San Francisco based firm.

  Customer service and technological expertise shine at Luminalt. Friends in Oakland raved about Noel Cotter and Luminalt, so we called them when our solar system malfunctioned. We first installed a solar PV system on our SF home in 1997 and upgraded to a bigger system in 2002. In 2009 a fuse blew in a breaker and the large East Bay solar company that installed our system blew us off. Another solar company in SF's Sunset district helped us out by replacing the breaker. Same thing happened in 2011. Again, the SF company helped us. But when the same thing happened in 2015, they didn't return our call. So we called Luminalt, who responded quickly. Noel not only got our solar running again but he's the only one who explained WHY this was happening, not just what was happening. This was not normal. A blown fuse should be a very rare occurrence -- I don't want anyone reading this to think that maintenance is a problem with solar systems. It's not! But if something does go wrong, I want someone like Noel on the job who can explain what to do for a permanent fix. If we ever need new equipment or service, I'm calling Luminalt.
