    5.0 Dorothy D. Westlake Village, CA

    The staff was very knowledgeable and helpful with a difficult inverter and internet connection problem.

    5.0 Melinda M. Thousand Oaks, CA

    We had our system installed about 7 years ago and had no problems until we realized it had a blown fuse a couple of months ago. We repaired it ourselves and then it happened again. We contacted Aeterna and they came out and repaired it and also recommended some important maintenance that needed to be completed. Before he came out he researched what we had installed and was very thorough. Ron was very professional and even came back out when we experienced another problem and worked to open a case with our solar manufacturer. I would highly recommend him for any new solar work or repair.


    At a time when things were too confusing for me to understand, Ron Harris at Aeterna Energy came along and took care of everything for me. He is very knowledgeable and gets things right the first time with no hassle. After installation, Ron has kept in touch with me via phone and email, always checking in and notifying me of problems and/or production, which is very appreciated. I feel confident in our system, and our service because of Ron. Thanks Ron!!

    5.0 Marc S. El Segundo, CA

    The company continues to be very thorough knowledgeable, and professional. In this business it is difficult to find an honest advocate for your solar install. Aeterna meets and exceeds all of those criteria!

    5.0 Caroline M. Van Nuys, CA

    I called a few different solar specialists before I decided on Ron at Aeterna. He was so comprehensive in his explanations and knowledgeable about all aspects of the equipment that I knew I had found the perfect person for the job. I was buying a new home with panels already in placed. His additional qualifications as a licensed roofing contractor also came in handy as he was able to advise me in great detail what work needed doing. Buying a home is very stressful so knowing I had such a methodical expert who gave such incredible attention to detail was a huge weight off my mind. I would recommend him without hesitation to anyone who wants the job done to the highest professional standards. Ron really went above and beyond - a thorough professional.

    5.0 Tim C. San Diego, CA

    Aeterna Energy representatives are very knowledgeable when it comes to photo voltaic system options, equipment, size optimization, and federal/state incentives. For our household, we elected to, not only, have solar panels installed but also energy storage (aka batteries) as well. Aeterna Energy assisted us in navigating battery storage effortlessly. The final project was completed on time without delays and, most importantly, it was within budget. As a fellow registered engineer and commissioning authority with 20 years experience, I highly recommend Aeterna Energy for your upcoming solar project. They are top notch!
