Abstract
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.
