ESP did a great job of installing our panels and battery. They were very professional, respectful, and got the job done within the time that they promised. I would highly recommend this company to anyone looking to put in Solar.

Ruined my panels

We have had several issues with ESP. Since last year (2024). Panels worked fine before ESP installed their batteries. We just wanted to add battery backup. Batteries added now our Solar panels no longer work. Smart asses state their batteries work. Well no shit it's coming from the grid. Worst experience we've ever had.

Reply from Energy Service Partners (ESP): We're sorry for any inconvenience. When we first installed your new battery, unfortunately we discovered that the existing solar from the previous company was not installed up to code, and so we have had to work to address the improper wiring prior to activating your new battery. We are not finished with your battery project yet and expect to be able to visit this week to coordinate next steps. Rest assured we always want to leave everything better than we found it and we appreciate your patience and understanding in the meantime.

The install from 08/24-Still wait the Technician to complete.

The customer service is bad, send to request for schedule . it take 2~3 to responds, and take another few more week for technician to come. I wish that I could review the SolarReviews earlier before signed the contract with them.

Still waiting for project to be finished

Process started middle of 2024. Initially expected for project to finish by August. By December, finally got approval from utility and county planning and building department. Panels were installed on December 23, 2024 and still waiting for the project to be finished. Been told project needed a "PV stamp" but utility and county know nothing about this. Still paying utility and now have to start paying for the system. Starting to get depressed.

ESP and their PPA is a scam!

This is a total scam, covered up with a deceptive sale process and further masked by the confusion created due to over 7 parties involved. This was presented as the Power Purchase Agreement via an agent of ESP Partners representing ESP as the PPA who would use my roof to generate power, and I would simply pay for energy with a fixed monthly payment of $268/mo. The promised "white glove" service was to be monitored, warrantied, and insured, AND I could cancel after 1 year. The financial models reviewed was a con-job. At this point, I'll be paying more for energy than if I had just stayed with TXU/Oncor with a non-solar traditional agreement!!!!! I only signed up with the guarantee that I could cancel after one year. When I became concerned, I tried to stop the process multiple times but I had a very difficult time understanding which entity to work with, and getting someone to follow-up with me. Now I cannot get an executive from any company associated with agreement to call me back. Looks like my credit will be wrecked, while I incur more expenses for legal support. NEVER DO A PPA, I could have bought this system for $45,000 with a ROI < 15 years.

Reply from Energy Service Partners (ESP): Mark, we're very concerned to hear about this situation. We do not employ salespeople but we expect all of the independent partners in our network to hold themselves to a high level of integrity and accuracy. PPA's are a valid financing option that many thousands of homeowners are currently enjoying across the country. Unfortunately we do not have a record of a project under your first name and zip code as you presented it here, but we do want to assist you with getting to the bottom of your situation - please reach out to support@joinesp.com with all of the details you mentioned above.

Don’t go with them!!

It’s been 8 months and we are still waiting to get our solar turned on. Horrible customer service, will never get back to you. I wish I never signed up with them.

Reply from Energy Service Partners (ESP): Gabriel, we're sorry for the length of time your project has taken. Because the electrical on your back porch was unpermitted prior to use starting the project, it caused a delay and snag in the installation and inspection process. We have scheduled a slot with a technician team who will be visiting to clean up the electrical now that the porch permit was secured, and then we will be able to proceed with inspection and activation of your system. Thank you for your patience and we look forward to wrapping up your project promptly.

Horrible Customer Service

I had my solar installed with ESP and it appears no issues with the installing excluding the damage to our swamp cooler my camera caught and I was home, when the worker's tool box fell off the roof on to it. Also they disconnected my lighting (electricity) in the back of my home and has not restored it. I have a rep name Iris who lack efficient communication with me, does not respond, or will not call me when I ask of her to get get clear information. This is not okay, and is unprofessional. I ask for the manager and was told over the phone by a gentleman, I was unable to speak with one, and hung up on me. I get a response from Iris through text only to say a mgr. will call. They set appointments with out consulting if I will be available for the appointment. Iris sets an appointment on Jan 20th (via call) for battery commissioning and nothing. It's sad the level of customer care, when we are spending our money and trusting companies provide decent services. I am truly reluctant to refer this company to my colleagues and friends who wants solar, my experience, I don't want to see others go through.

Ted | Clovis, California | 01/21/2025

Extremely disappointing experience. The project has been dragging on for over five months and is still incomplete. While delays due to permits or PTO are understandable, the real issue lies with ESP’s inability to submit documents in a timely manner. Their lack of efficiency and accountability is incredibly frustrating. Communication has also been terrible, making it a nightmare to deal with this firm. Definitely would NOT recommend. check this site for other reviews: https://www.yelp.com/biz/energy-service-partners-torrance#reviews

Reply from Energy Service Partners (ESP): Ted, we're sorry for the lengthy amount of time your project has taken. We acknowledge that there have been challenges but we are working towards the goal of finishing your project ASAP. To be clear, your installation is a newer type of interconnection known as a Multi-Tariff system; the documentation is brand new to the solar industry so there isn't as much precedent to lean on. Regardless, we know there's opportunity to improve and appreciate your patience and understanding while we get your solar up and running.

Think Twice before Choosing ESP

I would like to start off by saying that my main objective is to bring awareness to those who are in the process of choosing ESP for your solar panels project. I am having the worse experience with them because the panels aren’t producing enough energy and now I am paying Edison a large bill and also paying for my panels. The sales person completed his assessment and said I needed 13 panels to cover the usage, I even purchased 2 extra panels to make sure I had extra because my plan was to get an electric car. To give you more context, my mother used a different solar company and she has 15 panels as well and her panels are producing about 750-800 kWh a month and the ones I have are producing 80 kWh!!! Obviously, there is something wrong with my panels right?? Well, I have been trying to get ESP to send someone to my house to check what’s going on and the answer I got is that I have to pay for them to come check. I have consulted with other installers and they said that the panels were not installed properly because they are lying flat on top on my carport. I truly believed that ESP had experienced professionals that knew what they were doing, but based on the results, it seems that I have been left alone with this huge problem. If anyone else is having similar issues, please come forward and seek legal advise. We cannot allow this company to continue to fool people and they have to take responsibility for their actions.

Reply from Energy Service Partners (ESP): Isa, we're sorry to hear about the frustration with your project. Every home is unique and every family will need different system size as it pertains to usage and possible configurations, and other installers may have other protocols or tolerances for designing systems on carports or other non-roof structures, but everything we install is up to code and meets contractual obligations or else your system would not have passed inspection. We are always happy to review your power bills and compare to your usage to ensure everything is working to its optimal potential.

Horrific Company - Nightmare!

Nightmare company. Ground-mount gone so wrong. ESP is impossible to get anyone to answer a phone, return a call - quite frankly do any sort customer service. In 12 months, which is how long we've been dealing with this company and our solar installation has not even begun, we have had 3 different project liaisons, all completely ineffective. We hear the same answer when someone decides to address a text, calls are completely ignored - "I'll pass this on to the team ". Finally, we involved our salesman who gets the same run-around we do. ESP was surprised we have over $40,000 in 40 solar panels and installation materials sitting in our backyard, still on pallets. Someone had to have paid for this equipment - no one even knows about it! From what we've been told, EverBright pulled the funding (breach of contract??). ESP was notified, and never contacted us, or the installation company who they sent out - Solar Doctors LLC. Solar Doctors came out to begin installation, which was scheduled for 4 days. Broken and inadequate equipment, we now have over 18 holes on our yard measuring up to 3 feet wide and over 4 feet deep. A Butte County Inspector came out and told them, "I'll give you one more chance." They trenched a ditch approximately 100 feet long, 12+ inches wide, and 3 feet deep which runs across our driveway, and across where we enter our house. Installation at a stand-still, the trench was covered with a piece of 1/8 inch ply wood as a bridge so we could get to our house door. This setup has been abandoned. The rain has come, the ply wood has been soaked, and extremely slippery. This is now a HUGE Safety Issue. My husband and I are 78 and 66 years old!! ESP has not contacted us in any way. Not taking calls or answering texts - completely non-communicative. Nothing is happening, and we have this huge trench, an EXTREME SAFETY HAZARD! A slippery little board we must cross to get in and out of our home. We are astounded ESP doesn't see or care about their Legal Liability for Personal Injury!!! This entire solar debacle, involving 4 different companies, has become a senior couples incredible nightmare! STAY AWAY from ALL! We have decided to seek Legal Counsel. We have been left NO other choice.
