How Not to Install PV - Orientation & Shadowing Print E-mail

Orientation and shading issues

These are photovoltaic powered restrooms. The view is to the Northeast at about noon in February. The photovoltaic module provides power for operating a vent fan for a composting toilet.

In addition, the shadow cast by the vent pipe is shading the module and further reducing the output.
