No power

My system was installed around 4 years ago. I upgraded and added 5 panels last year. Just had a $550 bill and a projected this month bill of another $500+ and after multiple emails, calls and service tickets over the past two weeks still no call or care to have someone come and look at it and fix it. They only seem to care about install and after that they just don't care.

Solar system lost 60% of it's generation in just 3 years. Sunlux has been completely unresponsive with support. I can't even get anyone to come out and look at my system.

Thank you, Sunlux

Just want to say that Shawna was extremely helpful throughout this entire process. Shawna constantly answered all our questions and provided us with all the information we requested and I have to add, did it with a smile. Shawna never acted like we were bothering her. I must’ve called 50 times with questions .The entire team at SUNLUX was very professional. I recommend Sunlux if you’re getting Solar.

Easy, Smooth and Problem Free

Excellent walk through on the process by the estimation team. The installation was less than a day, once permits from the city had come through and the crew were really nice, courteous and seemed to like my dog (she likes to supervise). Clean and well-done installation. I thought the engraved likeness of the house with the solar arrays that was installed on the panel was a nice touch! Berlyn was excellent in keeping us up to date on what was going on and getting all of the paperwork sorted out and the permits in order. Kudos to Berlyn! Thank You!

Your search for Solar company ends here and if you're going with solar make sure to get quoted by Mike Valencia and Your Project Manager must be Shawna Vargas. Shawna was tremendously great form beginning to end. She went above and beyond to get me enrolled in NEM 2.0. She even worked after office hours and on her vacation day to communicate with SCE constantly to complete my application. She's the best and highly recommended. I would also like to thank Installation team Lead Kurtiss Reed, Omar Ceja, Dave Perry and Alejandro Cabellos. Also Inspection team Felipe, Michael and Adrian was the Great and made sure everything is up to date and passed city's inspection. I wish I can give 10 stars to this Company and team members. Thank you Sunlux..!!

Great Service!

Each team member that we worked with provided us with excellent service and follow up. There were significant delays with the city permitting (to be expected) but Shawna kept me informed each week that she was committed to pushing them along.

Very smooth and efficient and proffesional!

I have been researching going solar for a few years and just never pulled the trigger. I had decided a long time ago to go with Sunlux, for a few reasons but mainly because Don (gary) Lupo was very patient and willing to answer all my questions and concerns very clearly and honestly. I wish I would've gone forward earlier. I was really nervous to make this big investment but I was so very pleased how smooth this whole process was. it was a pleasure to work through this process with this team. Berlyn was so amazing with her proffesional and couteous customer service, at first I thought her emails were canned responses until i actually asked her something and her response was immediate, that goes along way with me! I also expected major delays and made sure I packed my patience because I came in right before the deadline of NEM 2. To my surprise the process went way faster and way smoother than expected and Berlyn was very efficient with her weekly communications and I was informed on what to expect at every step. I will gladly refer this company, it has really been a pleasure working with the whole team !!!

About SunLux

SunLux was started by 3 founders in very early 2015.  They have been in the solar industry for nearly 10 years and have seen it all and done it all with over 6,000 installations under their belt.   However, they had a vision to do things differently.  They built a business model that is one of the leanest operations you will encounter.  Why?  It means SunLux can beat any price and still offer quality name brand components and some of the best looking installations you will find!  Their focus is heavily customer oriented by staying in constant communication every step of the way.  They built a model that will support the customer during the process and many years after! Founders of SunLux have seen it all and have over 30 years of combined experience.  They founded SunLux to offer something different, a better kind of energy.  They are passionate about solar and saving money for their customers, but more importantly improving the quality of life and the environment around them.  They are also passionate about giving back to local schools and churches to better the community and make an impact on peoples lives.
