Spanish researchers in contrast two software program packages used to investigate bifacial PV programs. They discovered that PVsyst outperformed Comsol in calculating photo voltaic manufacturing in virtually all circumstances.
Researchers from Artistic Impression Analysis Heart Europe (CIRCE) in Spain studied PVsyst software program and Comsol Multiphysics software program to judge the efficiency of bifacial PV programs.
PVsyst is a well-liked worldwide software program bundle to review, dimension, simulate, and analyze knowledge from PV programs. Comsol Multiphysics software program is ready to remedy the entire Maxwell equation and service transport equation, providing an in depth thermal mannequin together with the principle self-heating processes that happen within the photo voltaic cell.
Each software program packages 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 think about components.
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 reminiscent of mesh, supplies, boundary situations, and solver setup.
The evaluation considers the parameters of website geography, orientation, system configuration, detailed loss, and module structure. The parameters that have an effect on the PV system efficiency are albedo, inclination, the space between the panels, and the peak of the land.
After conducting a number of simulations, the analysis staff concluded that PVsyst is extra direct within the calculation after figuring out the parts and set up location. Comsol gives extra detailed module efficiency research and correct thermal evaluation.
“With the identical simulation technique between the software program, PVSyst offers us the next worth for photo voltaic manufacturing in virtually all circumstances,” it mentioned.
Lecturers have discovered that rising the albedo values or distance between modules will increase PV energy era.
“So far as the peak, there’s a little irrational habits in the identical software program, as a result of a major enhance in manufacturing was anticipated however the end result was a small enhance,” they mentioned.
They offered their findings in “Multiphysics simulation of bifacial photovoltaic modules and software program comparability,” revealed in Photo voltaic Vitality.
