Solar Design and Installation & Energy Assessment Services

Drumriver Consultants founded in 2007 is a leading renewable energy and efficiency contractor. As well as performing comprehensive energy audits for homes, multi-family buildings, commercial, and industrial facilities, we provide complete energy systems. That means we not only identify the problem, we implement the solution.

We design and install Solar Electricity (photovoltaic) systems, Solar Thermal (space heating and domestic hot water) systems, and more. We balance the technical aspects of the project with the economic benefits of the solar system to meet your individual needs. We identify incentive eligibility while designing the most productive system for your site, and maximizing the return on your investment.
