Electrical energy storing and recirculating method for use in e.g. photovoltaic system, involves driving generator by pulling weight by motor at height during countersink, where pulling takes place in vertical or on inclined plane

摘要

The method involves driving a generator by pulling weight by a motor at a height during countersink, and producing current, where the pulling takes place in a vertical or on an inclined plane in such a manner that the motor drives a primary shaft directly. The weight is attached to a hoisting rope. The hoisting rope is attached to the primary shaft directly.
