Spanish researchers in contrast two software program applications used to research bifacial PV techniques. They discovered that PVsyst outperformed Comsol in calculating photo voltaic manufacturing in virtually all circumstances.
Researchers from Inventive Impression Analysis Heart Europe (CIRCE) in Spain studied PVsyst software program and Comsol Multiphysics software program to judge the efficiency of bifacial PV techniques.
PVsyst is a well-liked worldwide software program bundle to review, dimension, simulate, and analyze knowledge from PV techniques. Comsol Multiphysics software program is ready to resolve the entire Maxwell equation and service transport equation, providing an in depth thermal mannequin together with the primary self-heating processes that happen within the photo voltaic cell.
Each software program applications use the View Issue technique to estimate the incident irradiance on each side of the bifacial modules. PVsyst and Comsol use totally different simulation strategies, however PVsyst can calculate totally different parameters based mostly on albedo, irradiance, and look at elements.
The PVsyst software program simulates a bifacial PV system by calculating the irradiance on the back and front sides of a panel, and the power generated. Comsol software program can carry out simulations with a number of steps, together with enter knowledge similar to mesh, supplies, boundary situations, and solver setup.
The evaluation considers the parameters of web site geography, orientation, system configuration, detailed loss, and module structure. The parameters that have an effect on the PV system efficiency are albedo, inclination, the gap between the panels, and the peak of the land.
After conducting a number of simulations, the analysis group concluded that PVsyst is extra direct within the calculation after figuring out the elements and set up location. Comsol supplies extra detailed module efficiency research and correct thermal evaluation.
“With the identical simulation technique between the software program, PVSyst provides us a better worth for photo voltaic manufacturing in virtually all circumstances,” it stated.
Lecturers have discovered that rising the albedo values or distance between modules will increase PV energy technology.
“So far as the peak, there’s a little irrational conduct in the identical software program, as a result of a major improve in manufacturing was anticipated however the end result was a small improve,” they stated.
They introduced their findings in “Multiphysics simulation of bifacial photovoltaic modules and software program comparability,” printed in Photo voltaic Vitality.
