4.11 Integrated PV Shading
Shading devices are available that have photovoltaic (PV) materials which convert sunlight into electrical power. To maximize effectiveness of integrated PV shading, it should be facing south and as perpendicular to the sun's rays as possible. They may be used in any plane for shading but the power output will be compromised the farther away its placement is from perpendicular to the sun.
