How we designate or rate your system
(*) There is granularity based on the total number of bi-panels installed.
Prices will be adjusted up or down according to the actual ratings of the generator and condenser furnished.
Bi-Panels are mounted on stadia or bleachers which provide the alignment and inclination appropriate for each
site.
Installation includes the stadia, bleachers and all anchoring for the panel fields by concrete footings on land,
or various other suitable and approved techniques on rooftops.
All wiring and plumbing hot & cold is included with the solar field for a central or peripheral location of
the genset adjacent to the panel fields. Fields considered 'remote' from the genset(s) may incur and additional
pipeline cost.
O&M for the system is expected to be a fraction of a percent, mostly for condenser cleaning (typical of
HVAC)
Prices are FOB Norwalk, CT and include installation or an allowance for installer training (overseas only)
Area Requirements:
As a general rule, the land or rooftop area required for a given power rating is as follows:
small systems:
< 50kW - ~5,000 sq ft single row stadia, ~25,000 sq ft multi row stadia ( fully buffered rooftop edges )
medium systems:
60kW to 125kW - 10,000 to 20,000 sq ft single row, 30,000 to 60,000 multiple row (includes buffered edges)
125kW to 250kW - 60,000 to 120,000 sq ft multi-row or multi column stadia
large systems:
>500kW - ~2 hectare / 1MW -- excludes edge buffering, fencing, and cooling footprint -- or
~1 acre / 100kW -- with buffer space, access, fence, etc...
Areas are based on 8 hours at full rated power per average (median) operating day.
Bi-panels include fixed trough-trough spacing of ~50% of the panel width in included area.
Single-row solar fields do not require stadia row spacing allowing them to be smaller in included area.
Multi-row spacing is a function of site location (latitude) and is assumed here (45N) to be ~equal to the panel
length.
The combination of row & column spacing in the solar field prevents self shading allowing the system to
produce full rated power for >8 hours per day of sunshine at the equinoxes. Flat panels of similar rating
only provide full power from 2-5 hours per day.
Areas are larger than equivalent fixed-flat panels of to include collector trough spacing sufficient to prevent
any shading during single axis tracking.
We're looking forward to meeting your solar power needs.
