Last year we installed 2.8 kW on two Wattsun trackers with an SB2500D for
$30K. That included several site visits (120 miles RT), some AC service
rewiring, permit and interconnection fees, tax, etc. It excluded pole
installation. Another job used 1.2kW on a Wattsun tracker, also with SB2500,
and infrastructure (pole, conduit, tracker power supply feed, etc.) for
adding a second tracked array later, with 175 mile RT and per diem for the
crew, for $15.8K. A flat roof job was 1.5 kW with same inverter for $15.7K.
Our first batteryless GT system (installed on 9/11/00) was 2.24 kW and two
GC-1000s, installed without roof penetrations using 6X12 sleepers on a flat
roof for $27K complete. So that's $10.4-13.2K/kW. We lack the pitched roofs
in New Mexico, so all of our racking and mounting is custom to each job.
Very different story than California installs, I would guess!
