B6. Ambient temperature
Solar PV modules’ performance decreases with increasing temperature. Wind will reduce the
temperature of the solar array and will thus improve performance. Thus, it is important to install
rooftop solar modules with an air gap of at least 40 mm between the modules and roof

.
B7. Minimum distance from roof edges
Your solar PV design engineer should prescribe minimum clearance from roof edges that should be
