INSTALLATION REQUIREMENTS
A minimum clearance of 10 mm (0.394 in) or more between modules is required to allow for
thermal expansion of the modules. The clearance is from the plastic corner protector to adjacent
plastic corner protector.
To maximize your annual yield, find out the optimum orientation and tilt for PV modules in your
region. The highest yields are achieved when sunlight shines perpendicularly onto the PV modules.
Even minor partial shading (e.g. from dirt deposits) reduces yields. A module can be considered
to be unshaded if its entire surface is free from shading all year round. Sunlight should be able to
reach the module even on the shortest day of the year.
When modules have been pre-installed but the system has not been connected to the grid yet, each
module string should be kept under open circuit conditions and proper actions should be taken to
avoid dust and moisture penetration inside the connectors.
Connectors are not waterproof when unmated. When installing modules, connector should be
connected to each other as soon as possible or appropriate measures should be taken to avoid
moisture and dust penetrating into the connector.
According to UL 1703, any other specific clearance required for maintaining a system fire rating
should prevail. Detailed clearance requirements pertaining to system fire ratings must be provided
by your racking supplier.
Ground reflectance (Albedo) and Mounting structure height has an impact on energy yield of Bifacial
modules. Higher power output can be realised optimization of Albedo and module height.

MOUNTING METHODS
The connection of the module to the racking system can be created through the Clamps The
modules must be installed according to the following examples and recommendations. If a
different installation method is desired, please contact Vikram Solar customer service or technical
support team for consultation. Improperly mounted modules maybe damaged. If alternative
mounting method is used and not approved by Vikram, the modules will not continue to have a valid
warranty.
1.
Panels shall not be subjected to wind or snow loads exceeding the maximum permissible loads,
and shall not be subjected to excessive forces due to the thermal expansion of the support
structures.
2.
To maximize mounting longevity, Vikram Solar strongly recommends the use of corrosion proof
(stainless steel) attachment hardware.
3.
Vikram Solar Limited recommends mounting rails with a minimum width of 40 mm for ±
1600 Pa
