The McCalmont Difference

Solar is What We Do

At McCalmont Engineering, we stand apart from our competitors. Unlike engineering firms who design traditional power plants, renewables are not an afterthought for us. We do solar 40+ hours a week.

Construction Know-How

Our employees have years of field experience installing solar power plants, and that hands-on experience translates into lower construction costs. Our NABCEP-certified team knows what it takes to build systems, not just design them. We understand that you jump through many hoops to get your projects built. Through McCalmont Engineering's installation expertise, your projects become more viable.

Guaranteed Power Delivery

Our designs deliver more power over time. We’re so confident we guarantee it. If our design doesn’t meet its first year power generation objective, we will reimburse you the value of the lost energy. You can expect maximum performance and more capacity from your McCalmont Engineering design.

Years of Experience

Our staff has 50 years' combined experience in the solar industry, and that experience translates into buildable designs. We’ll help you coordinate every step of your project to get your systems built and generating faster. We know how to manage complex projects.
