A Grid Perspective; why Solar Trackers?

Dual Axis Tracking vs. Stationary

Despite the continued downward solar PV module price pressure, Solar trackers will remain an important component in tomorrow’s energy systems because of the sustained daily power curve.

With stationary solar PV systems, a daily bell shaped power curve is produced with maximum power produced at noon. As a result, a the power grid will have to be engineered to distribute the momentary noon time power production. A poor cost/benefit proposition.

Solar tracking systems will, because of the sustained power curve, provide the grid with a sustained power curve throughout the day. As a result, possibly little to no additional engineering efforts will have to be made to the grid.

It is the cost/benefit proposition from the grid’s perspective which will drive the need for future tracking systems, and this is something we will see in the way Power Purchase Agreements are about to be negotiated.
