Just don’t.

From beginning to now, it’s been painful. I selected them because I thought they would understand coastal properties. They don’t. The right hand doesn’t know what the left hand is doing. Every correspondence takes a week or two for a response. It’s been a year and nothing has happened on my property, though they have collected $13,500. They sent a handyman subcontractor from another company to get started, but he had the wrong equipment/electrical panel. He was not a licensed electrician but they were planning on having him install a new panel upgrade. I want my money back and to transfer my PGE interconnection approval and county permit to a new contractor. They say they plan to keep $5,500 of my money for the work they’ve done. Other contractors said the $1,000 initial deposit normally will cover the work they’ve accomplished (just NEM 2 and permit). So frustrating. If a warranty issue arose, I’m very doubtful they would even respond. Do yourself a favor, choose a better company. They are no longer recommended by Energy Sage. When you read reviews, filter from the lowest reviews. That is the real insight.

Excellent Service and Performance

Solar Union was easy to work with from my first interaction with them. I knew nothing about the different types of solar and they walked me through every step and even helped me compare different systems, setups and prices that competitors were offering. They were very responsive over e-mail and the phone and knowledgable enough to answer any questions I had. Honestly the entire experience was very positive, and the only hiccups came from issues with city permits or PGE applications, but the SolarUnion reps were always quick to provide any documents or guidance that would help move the process along -- none of the challenges had to do with SolarUnion themselves. Even after the install, the customer service is still very responsive and helpful with any questions about our setup. I'd recommend them to anyone in the market. The whole process was effortless, and for a project being built from the ground up, it was a breath of fresh air not having to worry about the solar system setup.

Spammers

Shortly after asking for quotes here, I got a phone call from SolarUnion. I had given no permission for any of my contact information to be release to installers. Note EnergySage's blurb on this from: https://www.energysage.com/about-us/company/ ""We protect all your contact information until you decide to share it with our installer network." Somehow, they managed to get access to my phone number in violation of that policy. Anyway, that call was from "Gelica from SolarUnion" at (415) 992-3283. Even though I've closed off my Marketplace by saying I've picked another (non-EnergySage vendor), I continue to get spam phone calls from them. Oh, and BTW, SolarUnion's quote here (as were 3 of the 4 quotes I received) was non-responsive: I put exact requirements in my request and they ignored them.

SolarUnion FTW

We chose to work with SolarUnion after analyzing offers aggregated on Energysage. SolarUnion was able to install our system before the promised delivery date and the system is producing at or above projections. We enjoyed working with the SolarUnion team on this project

Happy customer

My overall experience with SolarUnion was great. They helped us secure the NEM2.0 status in time, which made the solar installation more cost effective. I especially appreciate the expertise and great customer service from Josh Rhoades (Clean Energy Consultant), Erika Aguirre (Customer Experience Manager) and Itzel Navarro (Project Manager).
