this class, and adequate ventilation must be ensured between the back of the module and the installation surface. 
A safe working area also must be left between the edge of the roof and the external edge of the solar array. 

In the case of residential installations on the ground, modules must be installed following local regulations, 

e.g. using fence. 

5.3

TILT ANGLE OF INSTALLATION 

The installation of solar PV module string should be in the same orientation and the same installation angle. 

Different installation directions and installation angles will lead to the mismatches in current and voltage which is 
caused by different light absorption of different PV modules, this mismatch will cause the PV system power output 
loss. 

The  largest  power  will  be  generated  When  direct  sunlight  on  solar  PV  module.  For  modules  which  are 

installed on the fixed brackets, the best installation angle should be selected to ensure the maximum power output 
can be generated at winter time, if the angle can guarantee enough power output during the winter, it will make 
the whole solar PV system in the rest of the year can have enough power output also. 

PV modules are recommended to be installed at an optimized tilt angle to maximize the energy output. For 

detailed information on the best installation angle, please refer to standard solar photovoltaic installation guides or 
consult a reputable solar installer or systems integrator. Dust building up on the surface of the modules can impair 
module  performance.  ZNSHINE  SOLAR  recommends  installing  the  modules  with  a  tilt  angle  of  at  least  10°, 
making it easier for dust to be washed off by rain. Any faults caused by and/or attributable to tilt angle less than 10 
degrees are not covered by manufacturer's warranty. It is roughly equal to the latitude of the project site as a rule 
of thumb, facing toward the equator. Optimized system designs must incorporate other local requirements. 

Installation inclination refers to the Angle between the PV module and the ground plane, as shown in Figure 

5-1.
