Failure to follow these instructions could result in the destruction of the equipment or personal injury.
Do
install the modules with the junction box in the lower side.
The aluminium frames of ATERSA’s photovoltaic modules have side channels that make it easier to fix the module onto the profiles of the installation.
The Hook Fixing System is used to install the modules.This system can be installed on standard structures or “U” type guide rail.
Fixing on standard structures is carried out using the dead-end clamp, the M6 x 16 Allen screw, Grower washer, flat washer and M6 nut.
For this type of installation you need a 41 x 41 mm or 41 x 21 mm "U" type perforated profile. These elements do not come with the Hook Fixing System.
The assembled fixing should look like the picture shown in next figure:
*Note: In corrosive environments (salt spray), place nylon washers to insulate the panel from the metal parts of the structure.
Put the first two fixing sets in place, and ensure they are vertically aligned. Fully tighten the Allen screw.
Attach the other two fixing sets, aligning them vertically and move them along the rail until they reach the panel.
Check that the modules are horizontally and vertically aligned and fully tighten the screws to ensure the modules are firmly fixed to the guide rail.
The final fixing sets should be attached in the same way as the first two but in reverse. Take a module that is already in place and then attach the set of
fixings.
Ensure that the installation instructions provided in this document are followed. Guarantees or claims will not be valid if the described process has not been followed.
The safety instructions contained in this manual must be strictly followed in order to guarantee the safety of the user.
The cable pathway must provide mechanical support for the conductors and must provide sufficient protection, in accordance with the Low Voltage Electrotechnical Regulations
(REBT).
It must be handled by qualified personnel only. When exposed to the light, the modules generate electricity. If several modules are connected in series, dangerously high voltages may
be generated. To reduce potential electrical hazards during the installation process, it is adv
IMPORTANT:
NOT
Installation on standard structures:
Installation on “U” type guide rail:
isable to cover the modules with an opaque material. Do not touch the terminals with both
hands and always use insulated tools on the electrical connections.
Reversing the polarity of the cables destroys the bypass diodes of the junction box.
The module is not suitable for use under concentrated sunlight.
In normal conditions, the module can produce more current or voltage than the indicated for standard measurement conditions. So that, when dimensioning the system (cables
section, fuses,…) the Isc and Voc values should be multiplied by 1,25.
Modules must NOT be manipulated from the central part of the long sides of the frame.
The modules may be installed on plots of land, terraces, roofs and patios. ATERSA provides a series of accessories for installations on façades, windows,
balconies, walls and cornices.
In order to ensure optimum performance the modules must not be placed in the shadow of other objects (plants, snow, buildings, construction elements,
other modules, etc.), at least during the main hours of daylight.
The panels must face south if installed in the northern hemisphere.Guidelines for achieving maximum annual power output from a fixed installation are
provided below. A design period will be established in order to calculate the size of generator in accordance with the consumption requirements and
radiation. To determine the optimum inclination we will use the following table:
Do not install the solar module in a location where it could be immersed in water or continually exposed to water, e.g. from a sprinkler.
The installation in a saline environment must be done with isolators to prevent galvanic corrosion between the module and the support structure.
When solar modules are connected in series, they must all face the same direction and have the same angle of inclination. There must also be a proper gap
(minimum 30cm) between the module and the surface for ventilation purposes.
The ATERSA modules design allows the correct evacuation of water. They have open edges in the inside tube.
The modules must be installed on independent fixed structures. The structure must not transmit stress to the modules.
The longest side of the aluminium frame has a series of 6,7mm diameter drill holes. Use M6 stainless steel bolts to install it on the structure and the proper
torque values should be between 6 to 8Nm. The following bolt system should be employed:
The placement of the bolts, will be always at the distance B (except for ½ 6” 4x9 format modules, where the distance must be C), as shown in the image
number 12. Minimum 4 bolts per module must be situated.
The proper torque values should be between 8 to 10Nm.
The placement of the dead end clamp (Hook clamp or another type), will be always at the distance B (except for ½ 6” 4x9 format modules, where the
distance must be C), as shown in the image number 12. Minimum 4 dead end clamps per module must be situated.
Appropriate cable sections must be used to prevent voltage drops, which could cause a drop in the power of the installation. As a rule, voltage drops in
excess of 1,5% must not be allowed.
