Sicklerville, NJ

“Very pleasant company to work with. Keeps in contact with you after work is done to ensure satisfaction and help with questions. Excellent 5 star company. Highly recommended.“

“Very professional from beginning to end. Clearly explained all the options, gave a fairly accurate timeline , and followed through. The actual installation went quickly and was professionally completed. Having done electrical installations in my life, I was impressed by the choice of materials and the execution of the work. All locations of panels and wiring runs were cleared with us to keep the installation as unobtrusive as possible. Everyone we had any interaction with in this process, from initial meetings to the crews that came out to do the work, were very polite and professional. Couldn’t be happier with a project we had initial reservations about.“

“Excellent solar service. Get monthly emails regarding payment and billing. Save substantial costs on electric bill. Nice to know that we are working with a local provider that can answer our questions and meet our needs in real time. I highly recommend castle energy for solar energy. Thank you!“

“Very good experience from the beginning to the installation they explained to me the whole process in Spanish and there was always someone to answer my questions. I recommend the company to other families so they can save as I am doing thanks to Mauricio for his help always.“

“What a great experience with Castle Energy. Handled all the permitting paperwork. Installers were extremely courteous and professional. They took extra care not to disturb the abundant gardens. My wife Helen and I are quite pleased to have gone Solar and watching the meter spin backwards. The app also gives production and consumption results in real time, that we monitor.
No more surprises when the electric bill comes.
Thanks for helping us Go Solar!“

“Hector Diaz, my Castle Energy rep, was very thorough and helpful throughout the entire process.“


“Castle Energy is one of the best companies I’ve ever had the pleasure of doing business with. JR Castle is a stand up honest guy who made my transfer to solar so much easier. I had several companies come and show me what they had to offer but no one made me feel more comfortable then JR. Even after it was installed JR came back and showed me step by step how everything works. Also everything that he promised as far as the savings from the system was right on accurate. If you’re looking for solar, Castle Energy is definitely the way to go.“

To Hector Diaz explaining every option possible, to the workers who came to my house and put the solar panels up. I’m giving this company 10 stars if possible. Thank you.“

Williamstown, NJ

“Paul and Dakota from Castle Energy were amazing to work with! They were so helpful and made everything easy for us! Our solar panels look absolutely beautiful on our home. We will definitely refer them to everyone we know. Thank you so much, Castle Energy! “

“I would highly recommend Castle Energy if you are considering going solar. They are hands down the most dependable & honest company I have ever dealt with. In the beginning, JR showed my wife & I his proposal & took the time to explain everything thoroughly. He told us to think it over & call him with any questions if we wanted to proceed. That’s it. No pressure, no repeat call backs to try to just close the deal. (Like other Solar Companies I had spoken with). That showed us that he was confident in the quality of his custom workmanship. When the installers came to our house, they were very professional & answered all of our questions. I have seen other houses that had solar installed. Their cable, Sub-panel, AC Disconnect & solar system monitoring boxes are mounted on the side of the house where everyone could see. Not Castle Energy. They meticulously mounted the boxes in the basement & placed the cable in a location where nobody could see unless told. A very good crew. We are extremely please with their quality of work. “

“I was referred to Castle Energy by a coworker and have been very pleased with them. Staff was polite and the entire process went smooth. We are very happy with our decision to go solar through Castle Energy and would highly recommend them to anyone looking for solar.“

“They did great work at my house for the installation. They stood by their word and did necessary repairs. The workers were courteous and helpful and friendly and cleaned up. I’m very happy.“

“Great installers. Friendly, courteous, knowledgeable. Shown true professionalism. If you need or want any solar services Castle Energy LLC is the company of choice!“

“Castle Energy did a wonderful job discussing our solar options and helping us choose panels. Hector was our rep– it was a pleasure to work with from day one of meeting him. He never pressured us to purchase or rent solar, just laid out all of the facts and showed us real customers’ electric bills. Even now, 9 months after having solar up and running, I can contact him with any questions or concerns and he responds immediately. I’m glad we chose Castle and had Hector for this process!“
