trackers stays horizontal

[Paul Martin]

One of my trackers has remained horizontal since yesterday. It has been working well and this was sudden. The other is working fine. I have a call in but just wondering what could be the problem.

Likely a faulty sensor of some kind.
If it's staying table-topped either the wind sensor is telling it there's a raging storm going on, or it's not getting good info from the sun position sensor and the logic keeps it in its safe position (ie. table-top). Something along those lines (exact reaction of your tracker on fault conditions will depend on the brand, but in general, in case of a fault they all tend to table-top since that's the safest position to be in).

Already fixed. They replaced a part and it's working fine now. Apparently this part is failing a lot around here.
