  We haven't been paid by this company and the outstanding invoice is now more than 90 days delinquent. My solar company was contracted by Demo King Solar to perform a service call for one of their clients who was sold outside of the market they physically operate within (We are in TX and they are in DC). We were tasked to troubleshoot a solar panel and microinverter to determine which part was faulty. We completed our voltage tests as per manufacturer recommendations and took and submitted photos of the different steps we took during the inspection. It was initially determined that the solar panel was bad so one was RMA'd and the new panel was replaced during a separate visit and once it had been shipped/received. After installing and testing the panel, it was discovered that the microinverter was bad and not the panel. While onsite, we contacted Demo King and the inverter manufacturer to go through troubleshooting so that the inverter could be RMA'd. Once technical support agreed that the microinverter was bad and needed to be replaced through warranty, we were never spoken to again by Demo King or its employees Mike and Joel. Though our company followed the troubleshooting procedure as per the manufacturers recommendations, and even had technical support verify the steps we took to test and inspect the equipment while we were onsite, Demo King Solar stopped responding to our calls and emails after we performed the work and they have yet to pay the invoice and the amount they agreed to for the service we provided. ***It's incredibly important to note that we were initially asked to RMA a solar panel. After an agreement was reached and our technician was on-site, were were asked by Mike, from Demo King, to give him a call. At that time, they changed the scope of work over the phone and requested additional troubleshooting to take place while we were on site. We did so on behalf of the homeowner, who had been waiting months for this issue to be resolved.

  Had 18 REC Panels installed with Enphase inverters. From the time I signed the contact to installation and finally *** from ******* was a bit longer than hoped. I was hoping for *** in April/May 2024, ended up being August 2024. Despite the delays, system is operating well except for clouds and snow.

  Be very careful with the owner of this company, he is a dishonest person, he was paid an advance for the work and he never completed the work, he left the work incomplete, my recommendation if you do work with the owner of this company, do not give him money until the work is done. This is advanced if you give a deposit before starting the work to Mr. ***** owner of Demo King, he will not complete the work, what happened with our project, be very careful with this dishonest person, he tries to show that he is a great person but behind that human being there is a dishonest person. He took over $135,000.00. We will be end in court. He didn't even tell us I will refund part of the money. Am fair person and think he have to refund some money and he say no to that. Be careful.With this guy named ****** from demo king his the "owner"

  Looking for solar I got a text from Demo King Solar. They gave me the best price. I got back to them and discussed where the panels would go and how many. I also told them I had many other people come out and gave me prices. All the other company's said the tree next to the garage had to go. Plus all others said 19 400kw panels. These guys started out with 19 panels then changed to 15 panels. I had to pry another panel out of them. Back to the tree. They told me the tree was fine and sent out a inspector. Inspector said tree was no problem. So I went ahead and gave them a deposit. 3 months went by and still no solar. Meantime the tree has bloomed. I come to find the tree is blocking my roof by noon time. I told them about this and took photos. They said they noted and see if they could trim tree. Never mentioned to me I had to pay for a trim. I pushed the issue a few times since. Once they got permits and all was set to install they said tree was my problem and suggested I go ahead with panels and later down the rode get the tree removed. I replied I am a senior and I am on a fixed income. There is no way I could pay another 2 - 3 thousand dollars for a tree. I told them this was on them since they ignored the tree the whole time and it was there job to check for trees. Since I had to cancel the order for there oversight they charged me ******. Not a happy guy to pay for others mistake.

  These guys have done a great job installing 34 Q Cell Solar panels on my rooftop. I was concerned about the roof so much & they gave me 15 years roof penetration warranty unlike any other installer. Also they are locals so its a great deal to have this project done by Demo king team

  My new system has just recently begun to perform; it only went online last month. So far, there have been no complaints. I'm extremely happy. My first power bill, which I just got, only cost me $15. Not something to whine about. Derek worked as a salesperson. I couldn't have asked for a nicer, more respectful young man.
