Solar Trackers by Northgreen Energy Private Limited

“Solar Trackers” are devices that provides orientations to various payloads toward the sun.(In this case the payloads are Solar Panels) but otherwise they can be used for reflectors, lenses or other special optical devices.

In flat-panel photo voltaic (PV) applications, trackers are used to minimize the angle of Incidence between the incoming light from the sun and a photo voltaic panel,which increases the amount of energy produced from a fixed amount of installed power generating capacity. In standard photo voltaic applications, it is estimated that trackers are used in at least 85% of commercial installations, which are grid connected.It not only increases efficiency but also with increased efficiency lesser number of Panels can be used thus saving cost of the panels as well as lesser space requirements for the project.

Generally, Single Axis Trackers can increase the energy production typically by 25%, whereas Dual Axis Trackers can increase up to 40%,if correctly installed.

They may be classified into:

1. Single Axis Trackers :They are further Classified into two types depending upon which movement is desired to be tracked :
a. Vertical Axis Trackers.
b. Horizontal Axis Trackers.

2. Double Axis Trackers : Double Axis track both Vertical as well as Horizontal movements and are more complicated ones and thus expensive too.
