BP85s [RE-wrenches]

[Allan Sindelar, Positive Energy, Inc.]

Until the MPPT controllers came out, the only time we used BP90s (now 85s)
was for water pumping, and we often recommended against them to customers,
for the reasons given re higher MPP voltage being less useful. With MPPT, we
can harvest the benefit at higher voltage, which allows us in some systems
to save on racking, wiring, and other expenses directly related to array
installation.
