What are the California Flexible
Installation criteria? |
|
 |
The NSHP allows determination of expected performance using the
California Flexible Installation criteria, which bases the estimated
performance on an estimate of the performance for a range of module
orientations and tilts. The California Flexible Installation
criteria applies to all solar systems that are installed with an
azimuth ranging from 150i and 270i and all modules installed at the
same tilt as the roof slope for roof pitches between 1:12 and 7:12.
The PV Calculator allows the user to choose the California Flexible
Installation criteria for easy input and easy compliance. For each
system on each building that has the expected performance based on
the California Flexible Installation criteria, the Home Energy
Rating System (HERS) rater must verify that the modules are
installed with any azimuth and with any tilt within the acceptable
range. Note that in order to use the California Flexible
Installation criteria, each solar system on each site must meet the
"minimal shading" criterion. |
