If you use this company, you better hope you never need them to service or stand behind their work. We keep having leaks from where they installed our solar hot water. They came out over a year ago to fix it and with this most recent round of rains, it began leaking again. After leaving numerous messages, I finally got in touch to report the leak. I was told they were slammed and would put me on the schedule and somebody would call me. That was over three weeks ago. I keep trying to find out status of a repair, but nobody ever calls me back. Terrible customer service, A simple courtesy of a phone call would be appreciated.

Had alternate energy install a hot water system 14 years ago. That’s about as long as it lasted. Had to replace the pump about 3 times which was about $300 a pump. Called for a price for a new system, the $1000 discount is making it comparable with the other quotes I got. The numbers quoted is not realistic. Basically the pump system they use overheats the tank causing premature failure. Sales guy told me I got my moneys worth. Not to mention the digital gages fall off. I have friends who had their system for 30 plus years. Want a system to last, go with another company.

PV panel repair/replacement

Since May 2023 1 of 13 panels has not been working. AEI has not been able to resolve issue, still under warranty. Last 2 days I’ve been leaving messages for a call back, nothing. Hopefully after leaving this comment I’ll hear from them. Last time I commented I received a call less than 24 hours. Wish me luck.

Install Fail by Alternate Energy!

We have used AE (Alternate Energy) for 2 PV installs and 2 Solar Water Heater (SWH)installs on our homes. They were reputable until our recent SWH install on 5/2021. Upon inquiring with AE why our electric bill had a sudden spike in usage/ cost, they came to check our PV system which was okay. It was upon further research, that the SWH AE installed was not placed in the optimal location on our roof forcing our water heater to be on 24/7 as it never reached its peak performance. This resulted in our electric bill skyrocketing more than $500/mo. for more than 3 months. AE sent a tech to assess our SWH panels and upon their tech's review, the panels were facing the wrong way. AE came and relocated the panels but has not apologized, nor acknowledged their negligence, or offered any compensation for the unnecessary electric costs that I assumed. After many emails (to Yuko Ahina) and phone calls trying to get this issue resolved, I have yet to hear from anyone at AE. Furthermore, this city permit for the SWH is still open (job completed 4/2021) along with another permit they opened back in 11/2017 for a SWH that never was installed, this permit remains open as well.
