One of the most important aspects of designing a solar array is sizing module strings to operate within the parameters of the selected inverter. This is especially true for commercial and megawatt solar projects.
To help in this process, we’re providing a free solar design tool to our readers.
Ryan Mayfield, the Solar PV Technical Editor at SolarPro, and Renewable Energy Associates have developed a free solar design tool to help in that process. Most inverter manufacturers offer some type of sizing tool, but regardless of whether it’s simple or advanced, it’s usually limited to selecting only their products. The REA System Sizing Tool lets you select from a wide variety of products and manufacturers. This tool is used in Ryan Mayfield and SolarPro‘s HeatSpring course called Megawatt Design.
