  • "Recommend Altair Solar"

    Reviewed Jul 28, 2021

    My experience with Altair was fantastic, from the introductory phone call to the installation to the service activation. Every person I spoke to was knowledgeable and helpful. I appreciate their clear and transparent information about my project which helped me make good financial decisions.

    Best of all was their professionalism and quickness through the entire project. From the day I signed the contract to the day we got the system on, it took only 9 weeks. This was a nice surprise; it's common for this timeline to be more like 12 weeks.

    We are happy with our 8kw system. I compared costs between companies prior, and Altair was overall the best value. Add that to their service quality and Altair is a great choice.

  • "Great value for quality equipment"

    Altair solar provided the lowest rate from my initial conversation with them. Charlie provided me with every answer I was looking for. He was available consistently I'm on always get me the information I was looking for. I received quotes from at least five other companies. Even if they matched the price they cannot match the terms in confidence provided by Altair. After three months of pain in my system I have had zero issues and my system is generating the power I was looking for.5

  • "Excellent service"

    Altair's support was Grade A from start to finish. It began with a clear explanation of the system offerings and benefits by Charlie. He took care to answer our questions regarding the steps in the process and our role in getting the Association's approval. The latter was effortless based on the complete Engineering package provided by Altair. In fact, we were happy to note that our Association used Altair's template as an example of what they require.

    Once we committed, Sean visited the site and took time to explain the specifics of the proposed layout for our site. Sara and Hana kept the ball rolling and stayed in close communication with us. Together we were able to take weeks out of the committed schedule and we ended up being one of the fastest installations from start to finish they have done to date. We are delighted with the quality of the workmanship and are now up and running.

    For those comparing bids, take a close look at the warranties offered by each of the companies. Altair's were among the best offered in terms of leak protection, system performance and workmanship guarantees. We would highly recommend them to anyone considering a solar installation.
