6. Site Selection
Maysun Solar Modules can be mounted in landscape or portrait orientation however the impact of dirt
shading the solar cells can be minimized by orienting the product in landscape.
Solar module is recommended to be installed at an optimized tilt angle to maximize the energy output.
It is roughly equal to the latitude of the project site as a rule of thumb, facing to equator. But always to design
based on local situations to find out the optimum one.
When installing solar modules on a roof always leave a safe working area between the edge ofthe roof
and the external edge ofthe solar array.
In case ofresidential installations on the ground, modules shall be installed following local regulations,
e.g. using fence.
Position the modules to minimize the chances of shading at any time of the day.
Do not install PV modules in a location where they will be immersed in water or continually exposed to
water from a sprinkler or fountain, etc.
Avoid using a mounting method that will block the drainage holes in the module frame .
When all solar modules ( except for smart module) are mounted in the same plane and orientation then all
can be expected to have similar performance throughout the day and can be connected together to the same
inverter channel.
If solar modules (except for smart module) on the same installation are mounted at different angles or
orientations then energy production can normally be optimized by connecting the different orientations to
different inverters (or different MPPT if the inverter has more than one MPPT). Refer to inverter
manufacturers for further guidelines.
According to Intertek-conducted IEC 61701:2011, salt mist corrosion testing of photovoltaic (PV),
Maysun Solar modules can be safely installed in corrosive salt areas within proximity ofthe ocean or
sulfurous areas.
7. Mounting Instructions
7.1 Mounting methods
PV modules can be mounted to the substructure using either corrosion-proofM8 bolts placed
through the mounting holes on the rear ofthe module or specially designed module clamps.
Regardless of the fixing method the final installation of the modules must ensure that: The minimum distance
between two modules is 10mm(0.4in).
The mounting method does not block the module drainage holes.
Panels are not subjected to wind or snow loads exceeding the maximum permissible loads, and are not
subject to excessive forces due to the thermal expansion ofthe support structures.
Note: The drain holes cannot be blocked in any situation during installation or use.
A. Mounting with Bolts
The frame of each module has 4- φ 9 * 1 2 mm mounting holes, ideally placed to optimize
the load handling capability, to secure the modules to supporting structure.
To maximize mounting longevity, Maysun Solar strongly recommends the use of corrosion proof
( stainless steel) fixings
Secure the module in each fixing location with an M8 bolt and a flat washer, spring washer and nut as shown
in Figure 1 and tighten to a torque of 16~20 N.m( 140- 180lbf.in.).
All parts in contact with the frame should use flat stainless steel washers ofminimum o f 1.8mm thickness with
an outer diameter of 20-24mm(0.79-0.94in).
