PRODUCT UPDATE

Sun-link Solar Trackers meets Domestic Ontario Content: October 21, 2009

After a very successful season in 2008 thanks to the many dealers who promoted and installed the Sun-Link solar tracker, we are well underway with the largest production run ever. Our goal for this season is to drastically reduce the time between your order and the shipping date.

ALUMINUM MODULE BARS: One of the delays in getting your tracker out the door was due to the fact that the module bars must be produced after the order comes in. Painted steel bars required at least 4 days before they could be ready to go. The aluminum bars will be ready in 1 day.

EPOXY PAINT:
The new surface treatment is a 2 step process with an epoxy base coat and a UV resistant clear top coat.

SEASONAL ADJUSTMENT: Now you can set the angle of tilt from a label attached to the post. Adjustment is from 0 to 80 degrees.

NEW ASSEMBLY INSTRUCTIONS: We have refined the procedure to make it faster and easier. This is reflected in both the instructions and the new DVD video.

TECHNICAL NOTE: The Sun-link controller must be connected to a 12 to 48 volt DC battery or a DC power supply. Do not connect to the array cable. Maximum fuse size is 4 amps. Over fusing can damage the actuator, controller or array .

Under Development

Self Powered Sun-Link Solar Tracker

• Currently under development is a self powered version of the Sun-Link Solar Tracker.

A larger dual axis unit is in the development stage. As solar arrays get larger, the structure must get stronger. While dual axis is more expensive to build, and won’t have any advantage over the single axis unit for most of the year, it does offer one important feature; Strength.

The single axis unit size is limited to the available drive actuators. Dual axis units use a custom designed drive engineered to handle the wind loads presented by larger arrays. The dual axis unit will rotate around the main post and tilt as it moves keeping the bottom of the array parallel to the ground. This design is more easily scaled up as required.

The same reliable sensors and sun-link control circuitry will be used in dual axis units.

We are looking for feedback on how large of an array the dual axis tracker should be able to support. 2..3..4..5 KW. Engineering of the new unit will begin once we know what the market is looking for. Please send us a brief email with your suggestions to info@sunlinksolartracker.com
