Core Development Group online reputation

The majority of Core Development Group's happy clients have recommended them to others. The vast majority of their clients have praised the quality of their work and the competence of their employees. The company's dedication to its customers and its readiness to go above and beyond is likewise highly regarded. However, there have been complaints from some customers about the installation process and support. However, the industry still looks to Core Development Group as a dependable and trustworthy source of solar power.
"My panels finally started functioning after 9 months, but now I'm experiencing issues with my roof, even though my home was built in 2019. They opted to shut down since the installation was botched. It was a problem right from the start. Oh, and the battery is acting up, too. I'm up for helping track them down if anybody else is. All the harm they've caused must be compensated for." - Donald F.
"I, too, have heard similar complaints from others about the installation procedure being too long due to a lack of communication and inexperience. It was impossible to get in touch with anybody, and even when I did, I received empty assurances. The owner answered his phone after a long wait, but he pushed me off repeatedly. Now that the firm is insolvent and the panels are not produced as promised, we are stuck with no options. The owner was obviously trying to put me off since he was planning on filing, which explains his behavior. Looking for a lawyer in case I decide to sue the corporation or Goodleap. Is anybody having any success? Unfortunately, I still have to pay my energy bill and my solar panel bill to Core Development Group. If anybody knows a good lawyer, please let me know." - Samuel M.
"I have had nothing but problems with this business, as have a few others here. After failing to deliver for 11 months, they have apparently closed shop. I'm in support of the couple that has or will initiate the class action lawsuit. While going solar is still an option for me, I need to find a reliable firm to come and complete the work that has already been started. Unfortunately, it's not the roof of the home that needs fixing, but rather the roof of the back deck. In retrospect, I should have simply paid the cancellation money in March of 2021 and gone with my instinct." - Jovanny K.
"The solar panel installation that I paid for back in March of 2021 is still not done. The panels, however, have been paid for by me for the last 7 months. April of 2021 saw the installation of the panels. The wiring wasn't done until September. I've been told they're arranging my inspection for months now, but nothing ever happens. They decided to inspect on January 12th, 2022. Naturally, nobody showed up. I called before 5:00 and no one would answer the phone. Even after emailing, I received no replies." - Logan O.
"If you value your sanity, you should avoid working with this organization. I can relate to many of the stories posted here. My contract was signed in September 2021, it is now January 2022 and I still have no power. Numerous calls to customer service result in technicians being assigned, but they don't come or even call to cancel the call. Since I haven't even hooked up my panels yet, I have no idea if they will produce anything. It's insanely frustrating. PLEASE TREAT THEM WITH CAUTION!" - Frank K.
"This solar firm has the BEST customer service I've ever experienced. You won't find a more welcoming or professional setting than at Core Development Group, and you won't regret taking advantage of their free consultation—all it did was help me save money, better understand the process, and find a way to beat these utility companies. They are here to stay and provide a hand, so don't go looking for them. The help you've given me and my family is invaluable, so thank you very much!" - Terry E.
"We had a great experience working with Core Development Group to install a Tesla solar battery to our preexisting solar panels. Since our excess solar power is now stored in the battery, we can use it whenever the sun goes down without connecting to the grid. The battery is useful because it can keep the lights on when the electricity goes out, which is common during storms like hurricanes and squalls. The installers from Core Development Group were prompt, polite, and well-versed in what they were doing. They come with our highest recommendation!" - Jacob U.
"Despite the fact that there have been setbacks in getting my panels up and running. It has been brought to my attention that the installation schedule may be impacted by events beyond your control, such as lengthier-than-expected inspections or plan reviews. Lisa, however, whom I have just recently spoken with, has been quite helpful in addressing my concerns and answering my questions about my installation. She has been really helpful in answering my inquiries and calming my nerves. With her help, maybe we can move things forward more quickly and easily." - Taylor W.
"At year's end, I had a Tesla Powerwall installed as a backup for my solar panel array. They made it simple to close the deal, and they accommodated my budget and finance requirements to find a plan that worked for me. Some quotes were slightly less expensive, but they lacked key information such as what kind of equipment would be used or if any guarantees would be provided. I'm relieved that I can keep my house going with only solar electricity and a backup generator. I've had a few issues and queries, largely related to the fact that my home has a very crowded side and required a conduit re-run, and Core Development Group has always been quick to respond and help me out. They rushed to the scene to solve the problem." - Alex P.
"Core Development Group's service was prompt and thorough, and they kept us informed of the installation's progress the whole way through. They were very competent and expert in their field. They strove to provide us the ideal system by asking pertinent questions and guiding us to the most suitable option. Just got our February bill and were pleased to see that we were Net Positive (sold more kilowatt-hours than we used, resulting in a credit for future months)." - Jeremy C.
