ELECTRICAL SHOCK WARNING

1. This product generates an electrical current when the front side is exposed to light.
2. Even if voltage and current from a single module are low, touching the terminals or wiring may cause an electric shock or burns. These risks increase when many modules are installed together – generating higher voltages and currents which are dangerous and could be lethal. Photonic Universe Ltd will not be held responsible in any way for accidents, damage, and injury, including electric shock, caused by incorrect use or installation.
3. To avoid any risk, turn the front of the module away from the Sun or any intense source of light when wiring (alternatively cover the front side during the installation).
4. Do not use different types of models of solar modules in the same system.
5. Do not modify the electrical connections of the modules, in particular, do not open or remove the junction box.
6. Do not cut or pierce the module, this might cause live components to be exposed and/or damage the module.
7. Do not bend or apply excessive force to the cables.
8. Installation, maintenance and removal of photovoltaic modules must take place on dry surfaces.
9. Use tools with insulated grips only.
10. Do not use photovoltaic modules near flammable or explosive substances.
11. Keep the modules in their original packaging until the moment of their installation.
12. Do not use damaged photovoltaic modules (damaged during transport or installation).
13. Do not apply any protections, paint or varnish to the modules.
14. Do not drop heavy or sharp items onto the modules.
15. Do not concentrate sunlight (e.g. mirrors or lenses) or other sources of artificial light on the modules.
16. Do not dismantle or remove any part or label affixed by the manufacturer.
17. Do not install modules in locations where they may be submerged in water for lengthy periods.

HANDLING

Although this product has been designed to be robust, it must be handled with care:

• Do NOT bend or kink the module unnecessarily (note: the modules are flexible but should only be curved when mounted).
• Do NOT stand the module on its corners.
• Do NOT apply unnecessary force to the module (e.g. do not throw the module).
• Do NOT puncture the module.
• Do NOT step on the module before the installation.
• Do NOT lean the module on sharp or spiky objects.
• Do NOT use the junction box or the connection cable as a handle.
• Do NOT stack the modules (the sharp edges of the junction box might damage the front surface of another module).
• Store the modules securely in a cool and dry place. The packaging is not weather-proof.

Follow the above points to ensure that single PV cells do not break inside the module, and prevent damage to the protective layer of the composite.

MAXIMUM BENDING

• Photonic Universe modules of the FLPRO series are flexible, but they cannot be rolled up or folded. The maximum curvature allowed is up to the maximum bending radius of 2000 mm.
• Excessive or multiple bending must be avoided when handling the modules. The maximum bending radius, mentioned above, is only in order to mount permanently on a curved surface. The modules are not designed to withstand such a maximum bending radius for applications where this bending occurs periodically. Bending should also be uniformly spread; bending concentrated in one area might cause permanent damage to solar cells in this area.
• The module may be handled by the edge, but only if it is held vertically and without exerting excessive pressure to the edges of the cells. The modules should not be held by the short ends or corners as this may cause excessive bending under their own weight.

STEPPING ON MODULES

• Photonic Universe FLPRO series modules may be stepped on, but only when they are firmly mounted on a smooth, rigid surface, with no bumps, hollows or irregularities. Barefoot or soft-soled shoes are advised when walking on these panels – heels and shoes with a rigid sole should be avoided.
• Uninstalled modules or modules in removable installations must not be stepped on.

MECHANICAL INSTALLATION

While installing the modules, the installer must always follow general rules for safety at work, rules for electrical installation and devices, construction rules and all other regional and national rules and regulations.
Modules can be installed in a landscape or portrait orientation and fixed in place by gluing, screwing or riveting.

GLUING

• If your module does not come with an adhesive layer, gluing can be arranged by using an appropriate sealant/adhesive or double-sided tape. If adhesive is used, make sure it is suitable for outdoor applications (with a wide temperature range, UV protection, etc).
• The surfaces onto which the modules are to be glued must be very clean and dry. The installation must be carried out carefully and with precision, as this permanent method does not allow repositioning. The surfaces chosen for the installation do not have to be smooth, however in such cases the modules cannot be walked on, and the resistance against hail might be affected.
• If using a sealant/adhesive for gluing, make sure not to use the module until the glue is dry (typically 24h).
• Before proceeding with permanent installation we recommend checking the performance of the module by measuring the open-circuit voltage (Voc) and short circuit current (Isc) in bright direct sunlight with no obstructions, and comparing to the specifications. To achieve readings close to specifications, the sun should be high in the clear sky, and the module should be facing the sun directly.
• If your module comes with the double-sided adhesive layer, make sure your chosen surface area can form a good bond with the adhesive (for example do not attempt to attach the module to canvas or anti-slippery rough paint because such bond is unlikely to be strong).

Warning! For most smooth hard surfaces, the double-sided adhesive tape makes a very strong immediate bond with the support material and does not allow repositioning. Trying to remove a module, even if it is only partially attached, can seriously damage the solar cells. In order to glue the module with the double-sided adhesive tape, follow the steps below:

1. Recommended application temperature for gluing is 18°C to 35°C. Make sure all materials have roughly the same temperature prior to bonding.
2. The installation surface must be free from dust, grease and oil. If required, clean the surface with a degreasing agent. Loose paint or protective coatings must be removed or stabilized.
3. Lift the module and remove the protective film from the back, exposing a sticky surface. Do not allow contact with skin.
4. Attach the module to the surface. It is recommended to use two people, and a hand-roller in order to evenly spread the compacting pressure.
5. Note: to achieve full adhesive strength, leave at least 24 hours at normal temperature.

Avoid any unnecessary loads. Bonds must be made in such a way that no lever action (cleavage stress) can arise. Any shearing or tensile stress must be able to spread across the entire adhesive surface. Continuous peeling stresses impair the permanent elasticity of the bond. If your module comes with the junction box at the backside (FLPROJBB series), we do not recommend using a double-side adhesive tape to mount the module, especially on uneven surfaces with irregularities. Instead, please use a suitable sealant/adhesive to bond the module, applying it on the backside of the module and also a sufficient amount of adhesive all the way around the junction box. This will make sure that the module is mounted in a fully waterproof way for all weather conditions.

DRILLING / SCREWING / RIVETING

It is possible to drill through the module or alter its size by sawing. However, it is important to allow a minimum of 12 mm distance to the nearest solar cell or electrical conductor.
The edges after cutting or drilling have to be sealed afterward, in order to avoid moisture entering the fiber-reinforced composite material. A suitable sealant for outdoor applications can be used. Note that inadequately sealed cut or drilled surfaces will void the warranty. If your modules come with factory-installed eyelets, they can be used with appropriate quick-release fasteners or screws.

ELECTRICAL INSTALLATION

A photovoltaic module behaves like a current generator (such as a battery) and therefore has a positive and negative contact. If several modules are connected together, the total voltage/current of the PV array must be below the maximum voltage/current of the inverter, solar charge controller or the maximum system voltage/current of other connected devices, cables, and connectors. Please also note:

• The maximum module overcurrent protection rating of 20A needs to be taken into account when modules are connected in parallel.
• Do not connect modules with different orientations or angles of inclination in the same string.

1. The cables must have sufficient cross-section to avoid significant voltage drop. Always use specific cables for photovoltaic installations, resistant to atmospheric agents.
2. Warning! The modules have waterproof solar connectors on the end of the cable. You should never disconnect the connectors while the wires are active (solar panel under load). Connectors are only designed to be disconnected without any load.
3. Ensure that the cabling is not under stress. We recommend placing cables in cable ducts in order to have additional UV protection and prevention of cable pitch.

CLEANING AND CARE

1. Due to the special surface of Photonic Universe modules of the FLPRO series, dirt and grime are usually washed away by rain. Nevertheless, if the modules are fully or partially shaded by dirt or debris they need to be cleaned to prevent a loss of performance.
2. Clean the front side of the module using a soft cloth (dry or moist with lukewarm water). Do not use tensides, scrapers, or any high-pressure water tools (never use any greasy substance or a metal tool).
3. In areas with low winter temperatures, remove snow and ice without force (e.g. with a very soft broom) in order to not damage the protective layer of the photovoltaic module.
4. Inspect the modules at least once a year to ascertain that all connections and fixings are tight and corrosion-free.
