We researched several companies. Solar union was professional early on however. They are not comfortable with ground mounted units. Initial communication was very good however communication declined over the 3 month process. work was supposed to be completed in days however the project lasted over 3 months. I would not use them again for our needs because of the poor communication and follow through.

I am buying a house and reached out to get the solar panels that are on the roof assessed to see if they need repairs or replacing. SolarUnion sent someone out and they didn't even have a ladder. They spent 0 time looking at the panels and immediately jumped into sale mode to try and convince me to buy their system and have them replace the current one. I initially ignored the emails from them but then their agent called me and I told him very sternly that I wasn't interested and to not call me again. They have continued to contact me even after I have made it explicitly clear multiple times that

At first I didn't even want solar. Than a coworker of mine got solar and went with SolarUnion. So during the whole process I sat in to here everything that would happen and still could not believe it. So after a year of seeing his bill and mine I knew I needed to chance. at the time we were doing a remodel and talk to Randy and told him that I wanted to make the change but wasn't ready to pull the trigger. Another year went by, the whole time Randy would check in just to see how my wife and kids were doing but never asked if I was ready to make the move and that made me feel awesome not being bugged

We chose SolarUnion after getting quotes via EnergySage from 3 installers. SolarUnion wasn't the cheapest, but they had a great warranty and a knowledgeable team. We wanted a ground mounted array, that would require 250ft of trenching in our sloped backyard. The job was supposed to take 3 days, but once they started digging it was clear 3 days wouldn't be enough: the slope was too steep for the trencher to work, and there were too many roots. The crew worked for 5 days with pick and axe, carefully digging the trench to avoid hurting our trees. Top notch job. The rest of the install seemed super

Solar Union did a great job for us. I did a lot of research and got multiple bids through Energy Sage. Nearly every company backed off with the complexities of our installation with a flat roof encumbered with multiple exhausts on top of a 3-level townhouse. Not Solar Union that patiently looked at my drawings to make some initial assessments and designs for my review. The final system design optimized solar production while respecting the construction code. They took care of all permits and inspections with the city and PG&E and were amenable to the HOA demands.

SolarUnion installed our solar panels back in 2019. I'm copying this review from the one I left on Yelp for convenience, but I'm happy to say that two years later we've still experienced no problems.
SolarUnion was great to work with! Karissa was fantastic and clearly described the process, benefits, and performance expectations without any hard sell. SolarUnion was comparable in price (a little cheaper) than other quotes we received, but we were really sold on the customer service. The energy consultant they sent out (Mark?) was also friendly and answered all of my questions. Once I approved

Update: I called the inspector and was told they don't know why 3 separate permits were pulled if changes were made. The appointments for green tag and final sign off was schedule on two separate permits. 2 of 3 permits had open status until I called the inspector to have it cleared up. After we got the updated permits and submitted to pge then I got pto. I had to answer questions to pge even during the service upgrade. Taking measurements and tell them how the install would be. To be honest, if I didn't step in, the timeframe for pge would have been longer. You may think your doing your

Solar Union has been great to work with! It started with a free estimate and meeting that was super informative. They turned out to be the lower bid so we went with them and, three years later, have no regrets (and much lower utility bills)! I haven't needed any service yet but if I have any experiences to add down the line, I will. I highly recommend solar panels to anyone looking for an investment that will pay for itself and then more.

There are lots of solar providers in our area. I did several hours of research to determine which companies I felt were best for me. After soliciting bids and talking to representatives I choose SolarUnion and could not be more satisfied. They offer excellent service, competitive pricing, knowledgable advice, quick customer service and really walked me through it step by step. They acknowledged any delay and explained exactly what and when to expect. All permits, inspections, and any other bureaucratic paperwork was handled flawlessly. I followed several of their suggestions including one to upgrade

We had a great experience working with SolarUnion. After receiving multiple bids, we thought SolarUnion's was the most competitive and comprehensive. They took care of the permitting process which, though not fast, I was glad I didn't have to do. The install took a single day - the guys were incredibly efficient. The app that pairs with the panels offers more information than you could ever want. We've had to do no maintenance and received a refund from PG&E for producing more than we used. I definitely recommend them.

I bought my San Francisco solar system from Solar Union in 2018. Karissa has been a perfect go to person.
I have inquired on other properties I have to get additional solar systems and she has always replied right away.
I was so happy, I referred three of my neighbors and they love their system as well.
I have not bought a second system yet, but I do you plan on in the near future.

We chose SolarUnion in 2017/18 because the sales person charmed my husband who had resisted the idea of personal solar panels for several years. And as we looked into the product, we became convinced that the product being sold by Solar Union was top notch, with excellent technical services quaranteed. The entire installation process went smoothly.
During the ensuing 3 years I needed technical assistance once and the problem was solved instantly ....I recommend Solar Unionwithout reservation!

Great experience with Solar Union with planning, installation and follow up so far. We've had the system for close to a year now, and it has produced as promised. Worked with Itzel on installation and Erica assisted with the municipality rebate. They reviewed past energy usage, discussed plans for potential electric vehicle in the future, and recommended panel coverage to meet our needs. No electric vehicle, yet, but the extra capacity has helped with increased household use during COVID.

Well, they dropped off the face of the planet. Did something happen to this company? Their rep Karissa was very on top of it and responsive in her emails, then they sent someone out to take drone shots of our house and we were told we'd hear back in a few days..... nada. I've emailed her several times asking what's going on, and if they're still interested in our project - no response. What gives SolarUnion??? Even if Karissa is no longer with your company, SOMEONE should have reached out to us.....
I'm happy to update this review if/when reasonable to do so....

Loved the way they respected the COVID threat. They wore masks and where very professional in the way they handled this tough situation.
After reviewing two other solar companies, I chose them based on their high Yelp rating and because every single person I talked was genuinely interested in me and in my project.
The equipment they installed is rated as the best on the Market and the components were engineered to give the best performance over the life of the Solar Panels. I can watch my solar production from an app. My solar production is also reported back to Solar Union for them to use in

I am very pleased with SolarUnion. After being courted by numerous Solar companies, I finally decided with SolarUnion for the following reasons: 1) They have a local office. 2) They didn't overwhelm me with phone call after phone call. 3) They were patient with me when I had to wait off on the project. 4) Their sales rep Karissa G. was very thorough and explained everything in layman terms, because buying solar is like buying insurance, not easy and definitely confusing. 5) my house has a flat roof, many Solar companies avoid working on these types of roofs, the fact that SolarUnion was
