<p><b>New page</b></p><div>The module temperature Tm is calculated from the ambient temperature by the following formula:<br />
<br />
[[Tm]]=Tamb+kT[[G]] (6)<br />
<br />
This formula shows how the modules are heated up by the solar radiation. It is a very simple formula that doesn't take into account cooling effects such as wind. If your system is in a very windy area, this will reduce the temperature of the modules and this will help increase the efficiency a bit. The coefficient kT depends on the type of mounting used for the PV system. In general, a building-integrated system will be hotter than a free-standing rack-mounted system because the air cannot circulate freely around the back of the modules and cool the modules. In PVGIS we have used the following values:<br />
<br />
kT=0.035�C/(W/m2) for free-standing systems, based on measurements done at our laboratory<br />
kT=0.05�C/(W/m2) for building-integrated systems, based on values taken from literature <br />
