Armando (the owner), Luis, and Alfredo are complete liars. They will tell you whatever you want to hear just to get your cash, but the second you pay them, they disappear. They completely ghosted me. They stopped answering my calls, ignored my messages, and literally blocked my phone number to avoid finishing the work they were paid for. They took my money and abandoned the project. Do not trust Armando or anyone working for him. They are thieves, plain and simple. Save yourself the headache and go with a real company.

Sean was able to put together a…read morecustomized solution that exceeded all of our expectations at a very competitive price point making it a no-brainer. The tax credits made it that much more appealing. We just activated our solar system and we couldn't be happier with the results. Why San Antonio Solar was the choice for us? For starters they truly believe in QUALITY! The best products, backed by the best warranties in the industry, by the best installers. We have gone through the entire process working with Sean and David. We are so pleased with the attention to detail throughout. Their warranty is straight forward, products are backed for 25 years along with the installation. Simple! When talking with their installers, they also reaffirmed that SA Solar wants them to do quality work and not just rush through the jobs. Our solar solution included SolarEdge HD-Wave grid tied award winning inverter with integrated car charger. It is compact, efficient and so cool as far as inverters go! As part of the project we also asked SA Solar to build a pergola in our backyard and mount the solar panels on top tilted to the south allowing us maximum energy production. The team designed and installed a Gorgeous pergola that's also very functional, for us to enjoy for many years to come. Now that it is all set up, all we can say is WOW and THANK YOU to the amazing team at San Antonio Solar Panel.

They know their business inside out, and their customer service is outstanding. When the first set of batteries finally died at the cabin, they had new ones ready for us in no time. The install crew took two days to do our system in town, and by the time they were done they were our friends. Even our over-protective border collie loved them. They're simple the best.

My first comment of one Star last week was a bit harsh and maybe I needed to step away from the…read morekeyboard before I posted the review - I was seriously angry for no returned calls. I'd suggest to Greenstar Power to hire a dedicated Service Agent to handle phones and manage expectations for their customers. This, I believe would help the "Face" of the company meet their EXCELLENT Technical work. If I was rating this company solely on the work they've performed at my residence and previous interactions with Zach, it'd be a five (5) without a second thought. I felt to be fair to Greenstar and who I usually leave comments I'd removed the previous comment where my emotions seemed to rule the day to a this, a more logical and objective review of Greenstar and my experiences with them. I'm not sure what happened but last year when my inverter went out because of a lighting storm in the area I spoke and worked the issue with Zach. There were some issues with Solar Edge and Zack was able to work through those issues. It took a bit but it was on Solar Edge's end not Greenstar Power. However, this year when I had nine panels not producing power and I couldn't get a callback from the Service Department I was furious! Their customer service department in returning phone calls has was terrible! It took over six weeks calling multiple times a week, leaving messages with No response! I found an online option and left a fairly pointed comment and they reached out to me the next day. The following day, last Saturday, a crew came out and fixed all the issues. I will say that each time any of the Techs have been at my home they have been Fantastic!! Very professional and awesome work. As true as it is that Greenstar has incredible technicians and performs awesome work. It is equally true that Greenstar needs to fix the Customer Service phone answering/returning calls issues. It is the face of the company and completely distracts from the professional hard work your technicians conduct in the field.

Panels have broken several times. Getting them serviced is a nightmare, you call for help and they…read morealways quote week delays, then when the weeks are up no one has contacted you. Overpriced and worthless investment for us. Perhaps if they actually maintained function, but they're always broken and getting them fixed feels like I'm dealing with disrespectful and lazy teens that can't bother to actually answer a phone 99% of the time. I wouldn't mind even waiting for service if anyone followed up and communicated, but you have to turn into a loud whiny person to get any replies and even when I do I usually feel like I lucked out more than I was actually helped. This company steals money and offers zero service in return. Worst 'investment' in my life. I couldn't recommend it to anyone I didn't hate.

I am contemplating in to seeking legal actions against this company. I was not saving one penny. By bill has always been the same cause of my payment program with the light company. 6 months after it was installed they said they came and checked the system...that's when they stop working. So for two years I been paying the panels without them working properly. I really don't know if how much money I would be saving ( if they would be working properly). Try another company that will not screw you like this one. Bad services, bad customer service. but very efficient in getting their monthly payments for something that was not working. One word for them "CROOKS" For taking advantage of the elderly. this is my own personal opinion. I do have pictures to back up my review

We signed the contract in June of 2022 and had the system installed by August due to several delays... but it didn't get turned on until FEBRUARY of 2023. We were already quite upset about that and some other issues with delays in work, but fast forward to January of this year, and I found out that I have a roof leak. Nerd Power sent out a technician, and they identified several issues with the installation, INCLUDING A HOLE THAT WAS DRILLED OFF TO THE SIDE OF OUR PANELS THAT WAS NEVER PATCHED, FILLED...NADA. So the tech fixes all that but we identified water damage inside our wall. Nerd Power got a contractor to come out, and he identified they also broke the pipe of the hose bib that they attached the ground wire to from leaning on it, bending it and then truing to bend it back. AND they didn't install the ground wire properly, so it has already begun corroding. I will give Nerd Power credit for fixing everything, but our experience has been pretty terrible along the way and it wouldn't have happened in the first place if the work was done well. We are saving hundreds of dollars every month because of the solar system, but I would have gladly paid more money with another company rather than deal with all the hassle we have gone through.
