Solar Tracker 2-axis ST44M2V4P
This is a solar 2-axis tracker complete with rails, controller, linear actuator, nuts and bolts, etc to allow you to mount 4 60 cell panels. You will need solar panels of course, a small battery and a galvanized main pole with ground screws or other mounting.
This marvelous device uses a log to set angle and direction. In some ways superior to sun tracking methods as the panels are never confused. You set your latitude and longitude, the controller reads the parameters and automatically ensures that your panels are always facing the right way with the correct angle to maximize your solar collection.
Is it good value? Not really. You can add more panels for less money and get similar results with a fixed array. But for those who want something neat or really cool. And come on, a double axis tracker is about as cool as it gets. This is just the thing.
The tracker should give you around 30% more watts per day out of your array. The tracker holds 4 60 cell panels. If a 1 kw array is good for about 6 kw of production max. in our area on eastern Ontario, this tracker will give you 8kw. Realistically though, a tracker is most useful in the off season. When you get those cloudy days often you’ll get a sunny break, or lighter cloud, for a few hours. Now your tracker has your panels perfectly lined up. Now that extra 30% makes a big difference.
A tracker is also ideal for those who are space constrained. Or have tree shadowing problems. A tracker that has your panels perfectly lined up for early morning sun and later afternoon sun when trees block mid day. Perfect right. And cheaper than having two solar arrays each facing a different direction.
And did we mention cool. Imagine the excitement of children’s faces when they see the tracker following the sun. Smile. Too much?
Anyway. We have two. With shipping from Europe etc these things aren’t cheap. But here they are, in Canada. Ready for anyone who wants something really neat. Hurry tho. I’m thinking I want one. I mean. It is really cool.
