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!
