[RE-wrenches] Real world production data for bifacials?

[greg egan]

Wrenches, good health to you and your loved ones.  I have a client that 
thinks he wants bifacial modules since his site is in the Alaskan arctic 
and they have snow a significant amount of the year.  I've been 
installing standard modules on racks that can be set at 90 deg in the 
fall and set back to ~lat -15deg in the spring.  They are snow free in 
the spring when it's clear and cold and they definitely make more power 
than the ones I see siting with snow on them all year.  A 6.2 kW array 
will put out 5.8kW AC under perfect conditions (90 deg tilt, solar noon, 
clear sky, cold etc.)

Anyway, I browsed the archives and in general looks like they require 
special racking , clamps and raise the price significantly.  Have any of 
you installed some and seen increased power production in snow country 
and if so has it made up for the extra cost, extra labor etc.?  Have the 
modules been reliable? I'm looking for data on installed systems and 
maybe recommendations on where I can get price and availability on some 
so I can help my customer make an informed decision.

All the best,
