Positive Experience with Solar Optimum

Solar Optimum completed our solar application nearly two years before our installation could proceed so that we could get in before the NEM 2 deadline. Then they patiently waited for our home renovation to finish. Once we were ready, they promptly installed our system and only then did they charge us anything.

Didn't end up using Solar Optimum - poor communication

I had signed up for a solar system install and paid my deposit, and up until that point the communication was amazing. We ran into a snag with my roof needing to be modified slightly to accommodate the panels and they told me they'd get me an updated quote asap but only the part of the roof with the panels would be affected. This was on Jan 13. On Jan 27 I finally got the quote (after I kept emailing them) and was told I'd actually need to replace the full roof to install the panels. This had not been discussed before, and raised the price of the solar install well beyond what any reasonable person could expect to pay. I told them unfortunately this wouldn't work and I'd like my deposit back. I've been asking them for the deposit back since then and have not received it. What's concerning is if this is how they treat people who were still in the process of working with them, how do they treat people who have already paid and can't get a refund? Honestly their pricing is incredible, it's why I went with them initially. But now I see it's just not worth it. *Update* Solar Optimum reached out to me the moment I adjusted my review from 5 stars to 1 star. That's what it took to get a response - not my constant emails asking for an update. Nope! This review. And they only agreed to refund me if I deleted this review! I don't know if I got the refund from them or if my credit card chargeback worked but quite frankly I dont care and I'm ready to move on. Never dealt with a company like this before.

Good company- make sure to ask questions!

We were lucky enough to have a project that went pretty smoothly and quickly. Granted, this may not be everyone’s experience so make sure to ask question and time frames for each part of the project. They explained the standard time for each part which was helpful in what to expect so when the permits were pulled faster than expected and the utility approved the system within a few days it was a pleasant surprise. Pretty happy with the whole experience.

Run for the hills

This is the 3rd time getting solar. They talk a good game and offer a good price. But, at the end of the day. They can not truly offer what they said. They had me at 40 panels on one side of the house. Then, when they came back it was 30 panels on one side and 5 panels below that would only product 60%. Then, we had round 2. They had me 30 panels, and they pull the permits to install. Come installatiin day, they missed measured and we where now at 25 panels on one side and 5 infront of the house. Which once again the 5 panels would only produce 60% of what the should. Now, we are at round 3 and down to 25 panels. We will see how that goes. None, of this information was forth coming. I had to ask the production level of the panels and the loss. Then, because of there mistakes. They raised the cost of the panels. Because, i was no longer getting 40 like they quoted. So, i know now i am being over charged. It to a lot of back and forth to get above the so called managers you deal with to agrue the price. In 3 months i had 3 different so called manager handling my project and all those error where never caught. They, do not take fault for anything, nor honor the pricing that was quoted. So, run for the hills and as fast as you can.

Impressive Response..

This is an update to my original review in which I was very upset that I had reached out to Solar Optimum on two separate occasions and got no response for their quote to be updated and reflect a Solar array that was not oversized for my house. Since the incident, I was contacted by both the Sales Manager, Randal and the Executive VP of Marketing, Rainier. I guess there was a glitch on Energy Sage’s platform and they never received my requests. After some email exchanging, I can say from this experience they are a company that I will consider working with and would have no problem recommending them as well. Solar Optimum has done all they can to ensure my satisfaction and I haven’t even signed a contact yet, that is true customer service that is very hard to come across in these times. Thank you Randal and thank you Rainier, your kind words and eagerness to ensure my satisfaction has been very much appreciated!

Mason Brown was very helpful and knowledgeable. Answered every single one of my questions gave me multiple options for set ups. He would Answer every single call and text message. And believe me, those were a lot coming from an Overthinker. There was plenty of options out there for solar including the big name, Tesla who I was working with as well. Solar Optimum employees were on point. Helping every step of the way. From availability for inspections on the weekends and not eating to be home for install we’re very helpful for someone who is very busy during the week and can’t get off of work.
