    Sunlux install the Panasonic panels on my roof. At every process, Sunlux was courteous and efficient. They finished installations in a day (but took some time to get permits). The panels work great and I'm saving on electricity from the first day they started working.

  • Our experience with Sunlux was great from the time we signed the contract with the sales rep. thru the completion of the installation. A couple of weeks delayed with the install due to the rain, but that was out of anyone's control. Aside from that, everything went fairly smooth. Customer service was courteous and responsive. We'd definitely recommend Sunlux!

    The Sunlux solar process and installation was seamless and came together with their management of the City, HOA, install, and Edison. Beginning to end, 6-weeks and everything just as proposed. We took a long time to decide and vetted three other solar companies. Sunlux was competitive and worth a little for the peace of mind.

    John Linder 4/02/2019
  • SunLux is great. They called us to let us know there was an issue that needed fixing. Talk about being proactive!!!!! They came out and fixed the problem as it was an easy fix. But they went above and beyond and did some extra work to make sure that it wouldn't happen again. I am very please with them.

    5 star rating Sunlux won the bid.  Received quotations and inspections from three of the biggest solar companies.  

    Although the prices were similar, Sunlux was able to acquire a unique loan at an amazing interest rate.  Also, they did not try to oversell the number of panels.  

    Installation was fast (4 hours), clean, and almost invisible.  Looks great with no system...
