JA Solar has worked with Chinese scientists to test a new electrical heating system for solar panels that uses the heat from uncovered panels to remove snow. The system starts by using grid electricity, but then relies on the thermal effect of resistance to uniformly heat the whole PN junction area of the snow-covered panels.Scientists in China have developed a new snow-removal system for off-grid and grid-connected PV systems that makes very little use of grid electricity. The "domino-like snow removal system" (DSRS) uses electricity from uncovered PV modules to remove snow from solar arrays, ...Den vollständigen Artikel lesen ...
