WO_2021030109_A1

Resumen de: US2022376649A1

A dual drive shaft solar tracker system comprises a photovoltaic (PV) structure, which includes at least one solar panel, a support structure and first and second drive shafts. The first and second drive shafts comprise first and second belt mechanisms wherein movement of the PV structure occurs by wrapping belts of the first belt mechanism onto the first drive shaft and by wrapping belts of the second belt mechanism onto the second drive shaft so as to provide a non-linear wrapping rate to accommodate the non-linearity of the belt wrapping onto the first and second drive shafts. A linkage, which ties two rows that are unbalanced in opposite directions, cancels out the imbalance as long as both rows have identical components. This allows trackers to use PV modules of any size and weight and the perfect balance is unaffected.

Resumen de: US2022376126A1

A photovoltaic module incorporates a lamination including a back-sheet, an array of solar cells supported on the back-sheet, and a transparent protective covering over the array of solar cells. The solar cells are arranged in offset or staggered patterns on the back-sheet to present a more random and less rigid industrial appearance to an observer. In some cases, cleaved solar cell segments are arranged into groups that are staggered on the back-sheet. This allows for finer control of the net voltage produced by a module. In other embodiments, full single wafer solar cells are arranged into larger groups, which themselves are staggered on the back-sheet. In either case, the result is a photovoltaic module with an appearance that is more organic and acceptable to homeowners and architects than traditional modules having cells arranged in rigid aligned rows and columns.
