Ian,
What was the actual annual production for each array?
I ran a simulation, using latitude 47, and weather data for Olympia, and
using a module efficiency of 16%, which corresponds to Sanyo 190 watt
modules, and used 95% for inverter efficiency.
simulation at 47 lat, 36 tilt, south predicts
We have such a system in our area, NW WA. It was featured in the
cover story of HP124.
The roof angles are not exactly the same, but close (and I'm guessing
lower roof angle for west-facing would increase overall production --
??). In the first year, the west-facing array produced about 14%
Focused Energy can get some bifacials.

But to my point: Can anyone recommend a distributor for Sanyo bifacial
modules, specifically the HIP 190DA3? We were prepared to order them from
SunWize, but they haven't dropped their price much since 4Q08 and I'm

competitive on pricing and good people to deal with.

We just got a rebate confirmation from the Los Angeles Department of Water
and Power, after waiting 13 weeks. For those of you that might think this
number is a typo, let me be very specific: thirteen weeks. This is the
rebate reservation not the rebate payment.
But to my point: Can anyone reco

HI all
look at solmetric.com
I find most of the time PVwattsd is OK but I feel in some envoroments it is
off, I really like the work by Solmetric

Hey Folks,
Anybody have real data to compare productions for south-facing vs,
west-facing PV array? PVWatts is only showing about a 7% derating for facing
west.
Thanks,
Nik
factor derating properly.
It will be interesting to hear what other wrenches have to say.
