I've had my panels for two weeks now. Excited to see how things unfold. Vincent Cortese and the team he works with are attentive and prompt.

With having a handful of options for my solar project, I was very pleased to have picked Cortese Energy. All phases of the project were effectively and successfully executed, with everything being so seamless. For a project of this nature, I really didn’t feel it thanks to everyone that was involved. If you are thinking of going solar, I would strongly consider Cortese.

I am very glad that we used Cortese Energy Services for my solar panel installation. Vincent walked me through all available options and helped me to narrow down an option that works best for my situation. He is in constant touch with me throughout the process right from the proposal to the finsih stage.Vincent and his team (Jerzee & Sean) planned meticulously and completed solar panel installation on time despite challending conditions. They inspected my electric panel and evaluated connection options one day prior to installation. Solar panels got delivered one day ahead to avoid any potential delays on the installation schedule.Installation was planned in the first week of December. Vincent and his team showed up early in the morning and worked the entire day to finish the solar panel installation despite harsh winter conditions. By end of the day, system was powered on and started producing electricity.I recommend Vincent and his team for a professional & hassel free solar panel installation.

I used Cortese Energy again after working with them on a project about a year ago, and this project was even better than the last. I was approached by several companies regarding commercial solar for my business, but I knew immediately that I wanted to work with the CE team again. Their professionalism and experience made a noticeable difference—they streamlined the construction process and handled every step efficiently from start to finish. The execution, communication, and overall outcome exceeded my expectations once again.

Vincent is a total professional, and reliable build partner. Thank you for your continued commitment to uncanny execution.

Vinny is incredibly knowledgeable, transparent, and most importantly, trustworthy. I wasn’t too familiar with solar or what my options were but Vinny walked me through the various options and clearly outlined the costs for each. The crew was also very professional and friendly and they did a great job with the install. I would highly recommend Vinny and Cortese Energy.

I was left with an absolute MESS-by inexperienced, unknowledgeable, lazy electricians installing a 9.8 KWH solar system on my roof. Vinny, Mario, Alan-and crew members-were a dream come true! The finished left over work, fixed problems, communicated at all times, cleaned up messes they weren’t responsible for-were quick, efficient, knowledgeable, and absolutely a pleasure to have working on our home! I have worked with MANY contractors over the years-and these guys are the best of the best! You can’t go wrong! Don’t hesitate-give them a call!

We recently used the services from Cortese Energy to install Sunpower’s solar panels. They handled the installation very well and communicated throughout the process. Sunpower has a little bit of more lead time to deliver the panels, but we have heard their quality of the panels and efficiency to be good over the period of years! We go the U series panels with micro inverters. Overall would recommend Cortese Energy surely to anyone looking to go solar. They are quick from an installation process and ensure to answer all the queries one has! Thank you!
