4.1.7 Solahart modules are designed to meet the requirements of IEC61730 and UL 61730, application
the fire performance Class C (IEC61730) and type 4 (UL61730).
4.1.8 Due to the linear thermal expansion of the modules frames, the installer must ensure that the
minimum distance between neighboring module frames is 10 mm.
4.2 Tilt Angle Selection
The tilt angle of the modules is measured between the surface of modules and the horizontal plane, as
shown in figure a. The modules generate maximum power output when they face the sun directly.
Figure a: Schematic diagram of tilt angle
In northern hemisphere, modules should typically face south, and in southern hemisphere, modules
should typically face north. Dust building up on the surface of the modules can impair module
performance, Solahart recommends installing the modules with a tilt angle of at least 10 degrees, making
it easier for dust to be washed off by rain. At the same time, it is conducive to the flow of
accumulated water on the surface of the module and avoids long-term large amounts of accumulated
water leaving marks on the glass surface, thereby affecting the appearance and performance of the
module.
PV modules connected in series should be installed in the same orientation and angle. If the orientation
and angle are different, the solar radiation received by each module may be different, resulting in power
loss.
