How We Estimate Your Potential Savings

Your area: We want homeowners to manage their savings and their energy costs more intelligently. We can calculate the cost of electricity or other incentives based on your local zip code.

Your shade: Exposure to daylight can change for a number of reasons, including weather, seasons, and shade coverage. Solar panels can be more productive in areas with more sun exposure.

Your monthly bills: The more electricity you use per month, the more you can potentially save by making the change to solar. Now you don’t just see the savings – you can feel it in your pocketbook.

Experience, Innovation, and a Brighter Tomorrow

From custom residential systems to large commercial projects, we deliver reliable, high-performance solar solutions that maximize savings and sustainability. Our mission is simple: to empower homeowners and businesses to take control of their energy future while building a cleaner, brighter tomorrow for the entire community.

Customer Experiences That Speak for Themselves

    What a great experience
    “He guided us through every step with his team to make sure we were well taken care of.”
    - Silphy
    They left out no details in their plans!
    “We're very happy with the design (can't see from the front of the house) and more importantly the energy being saved.”
    - Suzzy
    Excellent company.
    “We have worked with Cobalt Power Systems for over 10 years.”
    - Jack
    Cobalt was among the most professional team that we have used
    “From the moment Drew put together a proposal through the professional installation/ QA / Handover to the homeowners I can honestly say that Cobalt was among the most professional team that we have used. The communication was top notch and the predictability of the dates was excellent. I can't recommend them enough.”
    - Ed K.
    Cobalt was reliable, effective, and knew how to get things done.
    “When I began looking into solar, it soon became apparent that I needed some help due to the complexity of this type of investment, as well as with the various tax incentives available to solar PV customers. Luckily, I was referred to Drew Johnson at Cobalt who helped immensely with this tedious and initially confusing decision. Drew not only helped in the initial decision process, but was involved throughout the entire engagement which provided me with great peace of mind. The installation went exactly as forecast and my Cobalt Project Manager Vince even helped to arrange some additional electrical work needed for my new high speed PEV charger. Cobalt was reliable, effective, and knew how to get things done. They made this a very simple and satisfying experience and we now enjoy the free power from our new PV solar panels every day”
