So zomeworks is done?
Darn

They used propane I believe for a lot of years. I think Freon maybe in the early days.

Sulas<http://www.sulasindustries.com/> is pretty new, but I've heard good things.  The concept is similar to Zomeworks, but they use paraffin wax instead of whatever fluid Zomeworks uses (freon?) with the intention of avoiding reliability issues while maintaining the simplicity and positive economics of passive actuation.

Have you looked at the Wattsun HZLA? No ladders and with the right module about 5KW tracked. Perfect for long hours of cooling or pumping. http://www.wattsun.com/products/accutrak-hzla-tracker

Chris,
We have used AER for trackers. We've had good success with them.

Dear people:
Now that Zomeworks is more-or-less down the tubes, what resources do you have for a residential tracking system?  Wattsun's 'one size fits all' really doesn't (and I don't need a need a lecture of ROI for buying more modules versus a tracker).  I'm just wondering if there are more options besides the utility grade models.  We have a great pole mount supplier – but some folks want a tracker.  I'm looking forward to your responses.
Best,
