Tips for Creating the Most Effective & Efficient Solar Plant Layout

The plan of attack for every new proposal should start with creating the most effective and efficient solar power plant layout possible. This approach not only benefits you as the customer in the form of efficient use of resources, but the team building the project in optimizing the hardware and processes required to construct on a specific site.

The Process

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. 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 layout that meets your criteria, but also 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, you may have to have the hard discussions about plant sizing if the professionals conclude you will not be able to reach your energy goals with the equipment specified. It would be unethical for an EPC to not inform the customer and to continue to build at their desired specifications, if after running the calculations their end goal was not sufficiently met.

Energy project developers should look for a partner whose mission is to arm clients with knowledge so that they can make the most educated decisions and avoid situations that may end up costing more to construct.

During the process of determining the optimal solar plant layout, you should be provided a very detailed layout of the solar site with the proposal. This layout is shared with the customer before the estimating phase begins to ensure the customer approves of the layout and understands exactly what the proposal will be based on. The layout takes into consideration how best to use the land the owner has acquired, but also to ensure it is efficient to construct; the ground coverage ratio (GCR) is optimum; the shading is minimum; and the design is safe to build — which will carry over to the maintenance crews having a site that is safe to maintain.
