AllSun Tracker

Single-Family Residence - August 2011

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:

http://www.allearthrenewables.com/ 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.

Advice:

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.
