Peter,
PVWatts would be your first free option. Interesting way to specify module power using efficiency and size. I don't believe there is quite enough information to do a direct calculation. The assumptions in PVWatts are based on location so it applies the single axis information. If really want to get serious, use PVSYST. Bill.

Can anyone help out with a set of calculations from 5.9kwh/(m2/day) insolation into kWh/kWp/year performance, given a 16.5% efficient poly-Si module with single-axis tracking @ 1.94m2 per module? Thanks so much! Peter D.
