Tips for Creating the Most Effective & Efficient Solar Plant Layout

The plan of attack for every new renewable energy proposal should start with creating the most effective and efficient solar plant layout possible. Getting the solar power plant design right benefits you as the customer, in the form of efficient use of resources, and the team building the project, in optimizing the hardware and processes required to construct on a specific site. Mortenson's Solar Energy team approaches every pv plant layout the same way: understand the site, then design around it, since layout is one of the first decisions in overall solar system design.

Why Solar Plant Layout Design Matters

As a solar energy developer, it is important to partner with an engineering, procurement, and construction (EPC) provider that takes the time to understand what you are looking for and then determines what would be feasible. Mortenson was recognized on Solar Power World's 2026 list of top solar contractors, a track record built in part on getting this step right.

The Solar Plant Layout Design Process

The process should start with a review of your solar project specifications in the form of alternating current (AC) requirements at the point of interconnection (POI), the direct current (DC) they intend to procure, and land available. Being open and transparent about how much equipment can fit based on the land area available and required spacing is critical.

The ideal EPC provider will not only create a solar plant layout design that meets your criteria, but explain why it may differ from what you might have received from a consultant. In building a project, safety and productivity should be fundamental drivers of scheduling. On occasion, this means having the hard discussions about plant sizing if the numbers show you won't reach your energy goals with the equipment specified. It would be unethical for an EPC to withhold that and continue building at the original specifications anyway.

Energy project developers should look for a partner whose mission is to arm clients with knowledge so they can make the most educated decisions and avoid costly surprises during construction.

Balancing Ground Coverage Ratio, Shading, and Buildability

During the process of determining the optimal solar plant layout design, you should receive a detailed layout of the solar site with the proposal, shared before the estimating phase begins so you can confirm exactly what the proposal is based on. The layout accounts for how best to use the land the owner has acquired, while making sure it's efficient to construct, the ground coverage ratio (GCR) is optimal, shading is minimized, and the design is safe to build and later maintain.
