![]() ![]() The software also helps in cable size calculations to minimize power losses.Ī nice feature we have found when using this software is the ability to directly compare the performance of different solar panel types, makes and models directly against the details of the solar PV installation site. pdf reports based on simple inputs such as the number and type of panels used in the design, the basic location details, the aspect i.e. SMA Sunny Design software generates detailed. SMA's Sunny Design software is a free to download and an incredibly powerful solar PV calculation tool. SMA is the world's leading manufacturer of solar PV inverters and solar PV monitoring systems. That said, when used as a tool to really understand what's going on between a solar PV array, it's location and the sun, it's superb. ![]() This tool underestimates the efficiency of modern solar panels and overestimates (default settings) the power losses that we would expect from a well designed solar PV array. Understanding the movement of the sun over a solar PV installation site is key to optimizing the performance and power generation of a PV system, the PVGIS is a great tool to use for this. Using this utility will give you the basic information needed to work out (1) the optimum pitch of a solar PV array based on it's location and height above sea level, (2) the amount of solar radiation available to a given location and (3) an estimated power output figure for your proposed solar PV system. If you have an understanding of this relationship as well as the access to the historical solar radiation data for your location that the PVGIS provides, you can prepare power output estimates (kWhrs), optimize system designs and have a very good idea of how a solar PV system will perform at a given location before a solar PV system is commissioned. The PVGIS Estimation Utility is a great way to understand a proposed solar PV system's relationship with the sun based on it's location. ![]()
