The Allsun Tracker has (20) 235 watt PV panels. It rotates in AZ and EL to get ideal sun tracking all day long. To understand how the tracker gets 40% more output than a fixed array, consider that in the summer my tracker is almost facing my fixed array in the morning and at sunset.

What You Need to Know

Description: We have a 20 panel version of this tracker.

Other Benefits:

By pointing directly at the sun from morning to night we can maximize our panels and charge the battery system quicker when PSNH goes down.

Maintenance Requirements:

A little grease yearly is all that has been required so far.

My Motivation:

We have panels aimed in slightly different directions to more efficiently charge batteries (E, SE. S, W and the tracker, which is optimized at all directions.


If you have the money and the inclination, get (3) AllSun (24) panel Trackers and a Tesla.

Experience with Installer:

The Tracker went up in a day! The paperwork was done for me and a netmeter installed. Paperwork for the $4500 NH Rebate was done for me.
