    I typically don't write reviews, but for Solar Vast I had to! They took the time to explain everything that comes with the installation process to make sure we knew exactly what we got ourselves into. And once we signed with them, they took over the process and handled it without a single hiccup! We're so happy with the result, we LOVE our system!!!

  • "Astonishing Service"

    Reviewed Aug 09, 2019

    I am beyond pleased with Solar Vast !
    Going solar was not a decision I took lightly. I did months of research in order to decide which solar company would be best for me and my family. I really loved the efficiency of Solar Vast from the beginning. Tiescha contacted me right away after my initial contact then I met with Janice for my home consultation. The installation crew who came out to install the solar panels, did so in a really clean and efficient way. They then proceeded to show me everything I needed to know about my new system and monitoring to ensure I was aware of each step in the process. It's also nice to have Tiescha and Janice direct phone numbers making the communication as seamless and easy as possible.

    Great panels and Even Better service.
    The team has been extremely helpful in getting my solar system, providing maintenance, and follow-up through the whole process. I feel safe and secure with my decision to go with them, especially with their 25 years warranty. I don't think anyone else can beat it.
    We had our Panels installed in 2011 and its been a great experience ...

  • "Quailty Product!!!"

    Reviewed Aug 09, 2019

    I honestly feel like it was such a blessing to come across Solar Vast. The whole process was seamless, and our agent was only a text or call away if we ever had any questions or concerns. He made sure we got all the permits we needed ( I wouldn't even know where to start ), and everything he promised - he over delivered. I can't say enough great things about Solar Vast! I'm so happy with my choice!

    Recently finished our New roof and Solar system with Solar Vast. After having a friend have his solar done by them we decided to get some quotes. Working with Solar Vast we got obtained a quote with value Product, Installation Service and Warranty. We are happy we did not go with the cheaper company, our neighbor went with a cheaper company that the service and quality of installation they received was horrible. Solar Vast was even great at moving our install date on short notice to better fit our needs. The install was quick and professional and very clean. The roof install team led by there roofer was very helpful everyday they were onsite. I would totally recommend this company to friends who are looking to get solar.

    "Trustworthy - Worry Free Solar Company"

    Reviewed Aug 07, 2019

    After much research we decided on Solar Vast for our solar needs. We have been extremely happy with our decision. Solar Vast worked with us and provided us a system that meets our needs exactly and was able to put some cash into our pockets,... We were not expecting that . Solar Vast is very knowledgeable and very detailed. Solar Vast will show you exactly what your usage is, how many panels it will take to accommodate that, not over sell more panels than you need, works with you to understand how to interpret your usage and how to manage it. Answers all questions/phone calls very quickly. Has a follow up schedule with you over the next 6 months to make sure you are getting the correct usage and not going to be surprised with a large bill at the end of the year.

    "Solar Vast saved us a lot of money"

    Reviewed Jun 14, 2019

    Our electricity bills used to be astronomically high, especially during the hot summer of Los Angeles when we had no choice but to use AC or else lose sleep due to rising temperature. However, after we had solar panels installed on our rooftop courtesy of Solar Vast, the monthly bill has been reduced drastically. Solar Vast is not only friendly and knowledgeable, they also gave us a great deal through their sales associates. Now I can't imagine a day without those money-saving solar panels at our home.

    As someone who’s really done my research in the solar industry, I can say without a doubt that this company offers the best service, gives you the biggest bang for your buck, and really tries their hardest to get you the best deal possible.

    Their customer service is impeccable. I’m used to having to wait on hold for a whole hour to reach someone, usually ends up being an automated response. But my experience with them was different - all my questions were answered by a real person, and they genuinely care about your experience with their systems. When they say they’re there for you, they mean it.

    I wasn't sure if I wanted to get a solar system at first. However, Solar Vast was being really helpful and answered pretty much all of my concerns. And I was well informed throughout the whole process.

    Overall, I feel good w/ the saving: it's almost like buying/installing a fresh money-making machine. So I would recommend the company to anyone who doesn't know which one to choose from because I don't think I could find a better one around my area.
