Customer Service is one of the worst I have dealt with. When I called because my system isn't reporting the lady claimed it was caused because of the electrical storm (which we had not had an electrical storm) I told her numerous times we had no storms but she didn't listen. I've called 5 times, still waiting for someone to fix the issue. No idea if my system I producing like they said it would be. I was told when they were trying to get me to sign the contract that they also monitor the systems and would be able to tell if something wasn't working correctly right away. Guess that was a lie, they do not monitor the systems, its up to me to check it daily. Would not recommend Sun Power to anyone. Worst customer service once you sign

Have had the system install and producing since March of 2012. I have kept month by month records since I have lived in the house. Central California is hot in the summer and my average monthly bill prior to the installation was $393 (that was over a 5 year period). After the installation the average cost per month was $110 a month.

I have a 22 panel system which provided 180% of our electrical needs last billing cycle. We got a $117 credit from SCE! Installation was done last July with some minor hiccups by a Sunpower crew. The install is one of the best I have seen. We monitor it daily and have had zero issues since going live. I would certainly recommend to all my friends.

They sold me a 58 panel system that was to generate more than 30,000kw per year to offset prior years usage by 100%. After 11 month of service the system has produced 19,595kw. Further, prior to initiating the contract I advised SUNPOWER that I have a steel roof and if walked on it would distort the stamped steel shingle. They assured my family they had experience with this type of roof and it would be OK. My roof is completely destroyed and they have admitted to that fact. They now are stalling to fix same. I suggest you consider other sources for your solar panel needs.

Have had our panels over a year and they look great and function extremely well. The company worked with us through the whole process answering all our questions as we went along. The installers were very professional and knew exactly what to do. In a single word, awesome.

This was one of three companies I looked at and it was the manufacture and online monitering that sold me. Never been happier.

Just purchased system. Outstanding service including sales, transparency, installation. SunPower was installer in our area, unlike several other companies locally. Must admit that your ranking Sungevity #1 for 2017 is odd since it went bankrupt last month!

My system was installed in 2008. Have not had any issues. Monthly bills are $5 per month so the system will easily pay for itself.

SunPower explained exactly how many panels I needed , where the panels were going to be placed and I received a 25 year warranty on panels and labor. All of my questions about how solar system worked were answered promptly. I especially like being able to access system and monitor usage online so I k now that system is working. I am not suppose to have to pay more than $37.00 a month for electricity. Bills have averaged $151.00 per mo. So far so good!

Purchased several months ago. Installed when promised, follow up excellent, functioning as promised and expected. No regrets.

Had solar system installed by one of sunpowers so called authorized dealers in 2016. My home uses 13000kw a year and was sold a 10k system. Since September 2016 the system has only produced 1600kw. My electric bill is over 200 a month and I now have a loan of 240 a month. What I was sold was not what was advertised. False claims and if you purchase a system from sunpower they will do nothing to help you if the dealer is bad. They only stand behind the system if it is leased. So buyer beware don't not buy a system from them. I am going to have to go to court to get the matter resolved. I paid over 40k for a system that will not save me money

My installation was done in September 2016 and have averaged an electric bill of $13 per month from my electric company. I am saving an average of $75/month. My salesman was excellent and he patiently explained what would happen and the timeline. The system works flawlessly and I cant wait to see what will happen in the summer with the central air and pool filter on.

Had Sunpower installed in 2016. Up to this date, March 2017, it has perforrmed without a problem. I am looking forward to summertime, when we use air conditioning 24/7 every day for 4 months. So far no problems and also no electric bills.

I took the leap 8 years ago and my Sunpower system installed by Baker Electric has now paid for itself. There has been no problem with the panels or inverter. Highly recommend Baker and Sunpower. My system produces more than they said it would! I like that, under promise, over deliver never gets old!

My solar system was installed 5 years ago in Bakersfield by "Sun Solar" utilizing Genuine SUNPOWER PANELS. It gets real hot here in Bakersfield. My typical former $ 500 to $800 per month Electric bills now average about $ 10. I keep my big house cool in the summer and save a fortune. I was a bit nervous before I tool the leap of faith and agreed to SOLAR> I am very Happy !
