Waste of my time

Heed my warning. DO NOT DO BUSINESS WITH SUNERGY. Signed the purchase agreement after three phone calls with Chris. Set up an appointment for site evaluation. Never have anyone shown up... Lost contact with Chris. At least I did not give any money to anyone.

Fraud of all Times

I can’t still believe that Chris Hammerstone from Sunergy Inc. is a fraud. Back in end of March 2022, I applied through EnergySage and received quote from Chris for Solar System Installation. The quote was reasonable, so I selected Sunergy as my solar system provider. I was fooled by 5 stars rating of Sunergy Inc on EnergySage based on 24 reviews. I received and promptly signed the “cost bound” agreement at end of March 2022. Chris stopped by my place within a week to collect the initial deposit check of $1000. I met Chris face to face when he came to collect the initial deposit. He sounded to be honest and nice person but “hey” looks can be deceiving. In mid of April 2022, Chris submitted the engineering plan for solar system to City of Irvine for approval, but his license with city was expired. There has been bunch of back and forth (slow and frustrating) between him and city to finally resolve the license issue and getting the plan approved. Finally on June 1, city approved plan and it was now the time to enter into next phase of project – i.e. acquisition of equipment and installation. Until then Chris has been responsive on text or phone – usually picking up phone or calling back in response to text message. He was responding at his will – though not a great experience as customer but still an acceptable behavior. Then on June 7, Chris dropped bomb on me by saying that he will not abide to the price quoted in the agreement because price for selected REC panels has gone up. At time of contract signing in April, he was very clear and promised that price will be abided because he already put a purchase request with REC. He offered me Solaria panels in place of REC400. Solaria panels are $50-$60 per panel cheaper in price so I told him to adjust the total price of agreement. Also I will be losing rebate of $400 from EnergySage that I was getting for REC panels. Once I requested price adjustment of agreement, Chris just disappeared from face of earth and never responded to email, phone and text. I have tried to reach him multiple times over the 6 weeks period to get update or discuss options, but I guess he decided to just gulp and never return my initial deposit. I contacted EnergySage (rep name Bob) and reported the issue I faced with Sunergy Inc. Bob and his management also tried to reach Chris for multiple weeks but were unsuccessful to get hold of him. At this time, I have lost all hopes to receive back my initial deposit or getting solar installation from Sunergy. I am a victim of a fraud and would request you all to beware of Sunergy Inc and Christopher Hammerstone. Also it seems that EnergySage doesn’t take any accountability on credibility of providers on their platform because they could not provide me guidance on next steps to recover deposit from fraudulent provider.

Solar installer

Chris and Michael did a good job installing my solar system. In a little more than two months I have the solar up and running. There was a problem which the solar panels were not matched with the final inspection report from SCE. This was immediately fixed by Chris. I am glad that we decide to go solar , go through Energysage , choosing Sunergy for our solar project. Chris is always available to answer my questions. It is a great experience to work with him and his team. It is very nice to be able to see how much energy we use daily and how much my solar system produces.

Great Decision

I had a few solar company representatives come out and explain/give their pitch on solar panels for my home. Seemed like I had different direction and answers from each and after all that, I still had questions. Chris at Synergy came recommended by ALOT of neighbors, so I thought I would try one last time. I am glad I did! Chris came in, spent a lot of time answering my questions and giving me the real deal with what solar can and can't do, how he works, the process, etc. I could tell right away that Chris was knowledgeable, responsible and real. Chris answered all my questions in a way I could understand and I was comfortable with (I am sure I asked many questions more than once). I have no regrets going with Chris and Sunergy.

Excellent from start to finish

We had been shopping for solar for about 6 months and had been in contact with a few other companies. What I found was either the prices were way to hight for our needs or the customer service was very poor. I got a recommendation from a neighbor to contact Chris Hammerstone with Sunergy. Right off the bat I could tell this was going to be a different experience that I had with the other company. Chris came over to the house and explained everything in detail and did not try to sell us on anything more than what I asked for or needed. From the time we agreed moving forward with the project it wasn't more than 3 weeks and the solar was installed and up and running. We have been very happy with our solar and the best part is the electric bill has been under $25.00. Best investment we have made

Fantastic Service!

Chris did a fantastic job! He personally took care of our home solar project. Took care of all agency applications and county approvals. Kept us updated on daily progress and delivered the system as promised. I would recommend his work any day!
