PV grid-tie output (Was PV roofing material) [RE-wrenches]

[Allan Sindelar]

Here are some numbers to toss into the output stew:
Our first batteryless system used 32 BP70s on two GC-1000s on a roof in
Santa Fe. We installed a Hialeah kWhr meter on the AC output. Between
11/12/01 and 8/1/02, we fed back an average of 8.54 kWhr/day from 2,240
rated watts of PV. One of the four subarrays was on a section of roof that
is partially shaded during winter months.
The GC-1000s have to date performed flawlessly, and the client is satisfied.
