Contacted PeP Solar’s “Customer Success Mgr/Project Mgr)” Mr Gorman Mishoski regarding problems I was having with my solar system performance & possible approach to solutions. Goran was “outstanding” in addressing my problems & possible solutions. He was very proactive with following up on actions & keeping me informed of the status on his actions.. For a young man of 24 years age he has a potentially outstanding future ahead of him. And, he will be a valuable asset to any organization he works for.

My solar system was purchased from and installed by a competitor of PEP Solar. The original vendor of our solar system jerked us around for more than 7 months when trying to get them to remove and reinstall our system to allow us to repair our roof due to issues unrelated to the solar installation. The original installer finally responded with a quote that was extremely high. I approached numerous solar companies trying to get assistance and finally found PEP Solar. Not only did PEP Solar respond immediately but their quote was half of all competing bids. During my search for help I checked with the BBB and Registrar of Contractors and discovered PEP Solar has been in business for years and has a great track record. if I could give PEP Solar 10 Stars I would. First off, since they did not sell or install the system they insisted I notify the original company to let them know the removal and reinstallation would be completed by PEP Solar. They then worked with our roofer to ensure we had our solar system removed and reinstalled on dates as promised. Their team was professional and wasted no time in completing their work. I doubt I'll need more work on my solar system but if I do I will NOT be using the original company who designed and installed it but I WILL use PEP Solar if the need arises. Bottom line, if you're planning on installing a solar system give these guys a shot.

Outstanding job correcting the mistakes the first installer made. We're powered with sunshine now and very happy with what PEP Solar did for us. Big thanks to Mike, Jason, Goron, Sean, and Bonnie.

PEP Solar did an excellent job for me to replace my 200A service with a 400A service needed to install a Tesla Powerwall + at my residence. After some initial glitches the project management went well and the install was made to the highest standards. The workmanship was superb, material quality excellent, and the worksite left clean after every day. The system is now up and running and performing well.

Pep solar has been absolutely phenomenal for our solar experience. I met Sean (COO) at an event and he’s guided me through the entire process. Mike did our installation and he gave us great information on how and when to use the system. I’ve now moved out of state for a new job and they still continue to be helpful as we sell our home and show the added value of our solar. I would 100% recommend Pep Solar to any family member or friend, they truly go above and beyond for their clients.

Professional design. Professional installation. Top notch quality! Great to work with and helped get us a total refund from SSVEC on the work that had to get done by PEP to fix SSVEC errors when our house was built! Installed 2 Tesla batteries also.

Mike and Goran were wonderful to work with! Courteous, knowledgeable and friendly. Thank you for the great customer service. ,
Although, the final solar system went flawlessly, I'm still a bit bewildered as to why it was needed. When paying for my warranty in 2020, a price tag of $300, I would think you would of warned me of the manufacturing company was out of business. Surely you knew that the panels were failing. And again when I had to replace panels, at a price tag of $500 a piece, you knew that you were giving me a defective product. I do appreciate you making the offer to replace the whole system at your cost and Mike and Goran were wonderful to work with. I now have a functioning system and happy that the whole ordeal is over.

My experience with PEP Solar was great! First let me say that I knew nothing about Solar and was educated by Dallas (the sales rep). I was in communication with Sean throughout the experience and even had access to the CEO (Bonnie) whom was quite gracious in assisting the process to go smoothly. We reside in Arizona where we had record temperatures last summer so the process did take some time as I am assuming PEP solar was inundated with customers. In my research I had received 3 bids from various companies and PEP Solar was very competitive in price using better equipment than some others and top rated Enphase micro inverters. The installer and foreman (Mike) was absolutely fantastic and installed the system quickly answering all my questions and told me to call him anytime in the future. Lastly, George (Goran), the project manager was a GREAT point person for us and followed up to make certain the process was completed to our satisfaction! I would highly recommend them and hope to add more to our system in the future.

Efficient, affordable, and virtually maintenance free, PEP Solar has many solar products to offer. PEP Solar has been servicing, repairing, and installing solar since 1978.
