I wanted to update my review to reflect what has happened since posting. After no response from customer service since 3/19, I posted my review on 4/19. Within 2 hours, Roy contacted us to schedule a meeting to discuss what was posted. After a pretty heated discussion on 4/29, Roy agreed to send a technician to our house the next day. Within 10 minutes of arriving, Drew found that a current transformer had been installed backwards during the warranty battery replacement they performed back in December, which was causing the house to draw electricity from the grid despite adequate battery and solar power. It was quickly fixed and our bills have returned to the minimum amount. Roy reimbursed us for all the extra HECO charges and sincerely apologized for our experience.

I am hopeful that we can rebuild our trust in the company again, because as I stated in the first review, many parts of Alternate Energy are excellent. I would recommend talking to Roy directly if you are having problems with customer service because he really goes out of his way to try to understand the situation and attempt to fix it.

QUOTED, INSTALLED. Perfect job. I had 3 bids and they were the only ones to show me alternatives for mounting positions and aesthetics.
First construction company to actually clean up after themselves.
and they did what they promised.

We've been a customer of Alternate Energy since at least 2011. We recently had our pv and solar water heater panels taken down and put back (by Alternate Energy) for a re-roofing job (by another company). While we thought that the cost of the job by Alternate Energy was quite expensive, we've had only exceptional service by their employee, Steve Sams. Steve was very conscientious and meticulous in everything that he did. He was always the last one to leave the job site (often 2-3 hours after everyone else) because he was trying to do the best job possible. He wouldn't quit until he solved a persistent excessive water pressure problem. He gained our utmost respect and trust in his knowledge and integrity. Thank you Steve for your 5 Star attention and service!!

From the first initial conversation with Sales Rep, Leeland until the complete installation, he guided all the steps with clear direction and expectations. The operations team did a great job with the electrical, panels and battery installation. Immediately saw the results of having solar and the long term savings we can expect.

We've had issues getting warranty service from them. It took a long time to get a collector replaced and they definitely did not help coordinate manufacturer support once their specific obligations ran out.

We installed a Mitsubishi split air unit with Alternate Energy in 2017. We were very happy with the installers and completed job. We continued to call them for cleaning and servicing since then. Making appointments usually involved a few attempts to get a response but not enough to frustrate us.

It is time to have our unit serviced again so I called to make an appointment. Their recording stated that it may take 24-48 hours for a call back. Ok, I waited but no return call. I left a second message and then a third over the next week. My last message I left expressed my frustration and that I would have to find someone else for servicing. I gave it a couple more days and still nothing. As I was always happy with their service I'm disappointed that I was forced to look elsewhere, which I have done.

We've been a customer of Alternate Energy for several years and are so pleased with their consistent service that we just updated our system with additional panels and a Tesla battery backup system. Although the entire administrative team is helpful and professional, sales representative Faith Texeira is an exceptional ace who knows the system inside out! Faith consistently and promptly responds to client inquiries and is a true 'mover and a shaker' for getting things done.....early and on time! Faith is knowledgeable, efficient, customer service oriented and a 5 star professional! Faith is a great Ambassador for the Alternate Energy brand and makes the entire team shine! Similarly, the electricians and installers for Alternate Energy are efficient, organized and very professional! Highly recommend Alternate Energy for any and all solar energy needs and Faith Texeira is your go-to contact to get the job done to specs and on time!

Have not received response from AEI after 3 emails to Casey. Still under warranty & they will not answer my questions. Is my panel that is not reporting on Enphase working? Is it producing energy? Your last correspondence in Nov stated ""There is nothing more to do"" yet my panel is still dark on Enphase app. You suggested I give a negative review about Enphase & not AEI. When I purchased PV it was with your company, nothing was mentioned if I should have a problem that I need to deal with Enphase directly. Yes you did come out to work on issue but not resolved & now you refuse to answer my emails.
Buyers beware. I was satisfied with AEI Until there was a problem. I'm still under warranty.

I paid $55,000 in May for P.V. panels and 2 batteries. It has been 5 months and I still haven't passed my C&C inspection yet. I wasn't getting much response but it appears they are going to make it a priority now to get the problems fixed. Will update later.
