Tracking not specific to the high Sierras but to Larry's point: In cooling
dominated regions, the loads are shifted into the later afternoons. Of those
10% winter gains and especially the 40% summer, half is in the morning when
it makes much more sense to put the additional cost that would go to
tracking into fixed West or Southwest facing additional modules. Much less
cost and much higher value.

Hello Eric,
With the low cost of PV solar modules, I would like to know why anyone would
choose to track the sun? It cost's much more and is a maintenance issue
compared to adding more PV modules to make up the difference. Tracking
winter gain is about 10% and summer about 40%. If there is no space
available for more PV it makes sense if you must have more production.

Given 310# snow load in the Sierras, what are some suggestions for a
superior pole-mounted tracking system? Right now I'm considering DHSolar,
but I'm unfamiliar with the product.
