Backward ray tracing for fast energy yield simulations

Scientists in the Netherlands have developed a model to forecast the energy yield of a PV system. It is able to take into account factors such as partial shading and multiple module orientations. Tested against a reference cell and pyranometer, the model showed less than 5% error, and the scientists claim their approach is up to three orders of magnitude faster than more common approaches using complex ray tracing.Accurate calculation of how much energy a PV system will produce in a given location is essential for proving value to investors and ensuring the optimal use of the technology.
