I had a great experience with ESP from start to finish. The team was professional, responsive, and very helpful throughout the entire solar installation process. The installation crew worked hard, kept everything organized, and completed the job smoothly. Communication was excellent, and they answered all my questions promptly. I’m very happy with the service and would highly recommend ESP to anyone considering solar. Thank you to the whole team for a great experience!

We had what I assume was a larger residential installation and the service was fully functional within 2 days. The crew communicated well, consulted on placement and requirements, and kept a clean work environment. The power was only disconnected for a short period of time on one day. Very impressed with the collective service!

The installation went precisely as planned and the work that it took to install the system was top notch. There was a bit of a communication issue but, it was incidental to the overall installation and was with one of the installers. This system was installed to augment our original solar system provided by a different company. Working with Energy Service Partners was a pleasure. The other company not so much.

12/10 services. Going into this process I had so much anxiety and was not sure if everything would go smoothly. They have made it to where I have not had to worry one bit. Each person I have dealt with has been so kind and professional, especially our installer crew. Stephanie has consistently kept me updated on each step of the way and made sure I was in the loop of it all. I have to give them a shout out as they finished the job so quickly, efficiently and anytime I went to check on them they were always working hard plus they cleaned up absolutely everything! There was not one spec of work material left behind. I would definitely recommend ESP to anyone who uses them.

Install as expected

insulation was smooth, quick with no issues. Installer was great, clean timely, and communicated through throughout the process. The one suggestion I may have, is understanding the process between completion of installation and getting your permit to operate with the utility. Other than that installation and usage is as expected.. great work.

Gaylar Dempsy is one of the best customer service managers. She has been my contact person for our roofing installation and it's warranty. I can't be more pleased. First of all, she is very accessible to contact with. Second, I didn't have to repeat my inquiries. She has knowledges and experiences to provide the solutions without delay. She always makes sure that I am satisfied with her assistance. I think she is a great asset to the company.

I recently had the pleasure of working with Energy Service Partners through EnergyPal for my solar installation, and I couldn’t be happier with the experience! The entire process was smooth, professional, and completed in a very timely manner. From the initial consultation to the final installation, the team demonstrated a high level of expertise and commitment to quality. Not only did they deliver exceptional service, but they also offered a fantastic price that was very competitive. It’s clear that customer satisfaction is their top priority, and I felt well-informed and supported every step of the way. The installation was completed on time, and the team was courteous, respectful of my property, and left everything clean and tidy. I’m already seeing the benefits of the system, and I’m confident I made the right choice. I highly recommend Energy Service Partners and EnergyPal to anyone looking to go solar. Their combination of professionalism, efficiency, and great pricing is truly unmatched!

Solar review

The installers were on time as scheduled and professional. Panels look awesome. Adding two backup batteries as to have plenty of power throughout the day and evening or especially blackouts ! Our Edison bills have sky rocketed. Almost tripled as of July and only going to get worse over time. I’ve been well informed every step of the way. Our Representive,Adam, has been awesome. Always answers my questions almost immediately and follows up on everything he’s says he going to do. Will totally refer them to all my family and friends. This isn’t a short process, as the city has inspections and permits that have to be approved. No pressure was given at any time. Extremely happy we made the decision to go solar. Only going to get easier to manage our bills knowing exactly what I have to pay for electricity. And the electric bill will never go up. Never hurts to get a quote. No obligation. Totally satisfied.

That you very much for the review! We're so glad you made the decision and we're confident you'll love the system for many years to come.
