The FuturaSun photovoltaic (PV) modules, including models FU XXX M / MV / P / PV / NEXT / NEXT PRO, are designed to convert sunlight into direct current (DC) electrical energy. These modules are primarily intended for use in grid-connected photovoltaic systems, but can also be integrated into battery-powered, stand-alone systems. Optimal performance is achieved when the modules are properly installed, typically oriented towards the South in the Northern Hemisphere, with their surface positioned as perpendicularly as possible to the incident rays of the sun. Avoiding any shading from obstacles in and around the installation area is crucial for maximizing energy production. The modules' electrical performance is significantly influenced by the intensity of incident solar radiation and ambient temperature, with higher temperatures generally leading to a proportional reduction in electrical output.
The FU modules are certified to meet or exceed the requirements of IEC 61215:2016 and 61730:2016, covering flat-plate PV modules and panels for installation on buildings or as freestanding units. They are not designed for use with artificially concentrated sunlight. Installation should only be performed by authorized personnel, adhering to the latest IEC codes and local building regulations. It is essential to ensure sufficient ventilation for the module backside and to adapt the mounting configuration accordingly. No additional holes should be drilled into the module frames, and drainage holes must not be covered. Pre-assembled mounting systems require written confirmation from FuturaSun in advance. The modules can be mounted at any angle, from horizontal to vertical, but the junction box should never be positioned upside down. For optimal exposure to direct sunlight, modules should be oriented towards the south in the northern hemisphere and towards the north in the southern hemisphere.
When handling and installing the modules, protective gloves should be worn to guard against cuts from sharp edges and skin burns. Care must be taken to avoid breaking or scratching the front cover glass and to prevent mechanical damage to any other part of the module. Modules should not be carried by their connector wires, as this can lead to electric shock or damage. It is crucial to avoid trampling on, scratching, or dropping sharp or heavy objects onto the module surfaces. Modules should not be subjected to impacts, especially near the frame edges, or mechanically flexed. Since the modules are made of a single laminate, they are not repairable once damaged. If any part of the module, front or back, is damaged, it could become electrically active and dangerous, particularly if connected in series to a string. Therefore, installation or handling of wet modules or during high winds is prohibited.
Electrical connections must be made with extreme caution. The risk of serious injury or death from electric shock or arc flash is present, and modules should never be connected or disconnected under load. Even when protected against accidental contact, high hazardous voltages can occur during installation, making it imperative that only authorized and qualified persons perform installation and maintenance. Before connecting the system to the grid, the PV system must be approved by the responsible electrician and local electricity company. The PV system design should be carried out by a qualified person familiar with PV system design.
Under normal operating conditions, a PV module may produce higher current and/or voltage than reported at STC. Therefore, the Isc and Voc values marked on the module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor current ratings, fuse sizes, and the size of controls connected to the PV output. The FU modules are qualified for protection class II against electrical shock, in accordance with IEC 61730-1:2016.
For grounding, the module frame or array must be grounded before wiring, using certified materials and performed by a qualified electrician. The grounding area for the wire must be clean and free from oxides or debris. A separate approved ground wire should be attached to one of the holes marked with a ground label on the module frame, using an IEC approved ring terminal or IEC listed grounding lug. The Voc should be adjusted by a factor corresponding to the lowest ambient air temperatures expected at the installation site. If this information is unavailable, a 1.25 multiplying factor can be used as a default for Voc correction.
Modules can be connected in series, parallel, or a combination of both to achieve the desired electrical current and/or voltage. In series connections, the Voc is the relevant value for calculating the total voltage, which must not exceed the maximum system voltage of 1000 V for FU XXX M, P, M NEXT, M NEXT PRO modules, or 1500 V for FU XXX MV, PV, MV NEXT, MV NEXT PRO modules, even at low temperatures. It is crucial to use the same type and rating of module throughout an installation. For parallel connections, fusing may be required, with fuse sizes determined by local environmental conditions and regulations. A FU module string in parallel should not be subjected to a total reverse current higher than the Ir value specified in the datasheet. The total voltage of series-connected strings must be compatible with the input voltage range of the inverter.
The FU modules are designed for use in grid-connected systems, linked in series/parallel combinations to feed a dedicated inverter with a DC input and an AC output of 230V/380V AC - 50Hz, providing energy to the local electricity grid.
While PV modules do not require routine maintenance, periodic (annual) inspection for glass damage, electrical connection integrity, and corrosion is recommended. Under normal conditions with sufficient rainfall, cleaning is not required. However, in extreme climatic conditions, accumulated dirt on the glass front cover can affect electrical performance. In such cases, the front cover can be washed with water (no aggressive cleaning solutions, chemicals, or abrasives) and a soft cloth. Extreme caution must be exercised when applying water to any electrical device.
To prevent electric arcing, both the connection and disconnection of module connectors, and Voc measurements, should be performed with the string of modules in open-circuit conditions. Additionally, Isc should be measured for each individual module in short-circuit conditions.
FuturaSun ensures that FU modules are packaged appropriately to guarantee maximum safety and protection during transportation and storage until installation. Modules should be transported in their original packaging and protected from mechanical stresses. Each package is designed for shipment and storage, maintaining module integrity if FuturaSun's instructions are followed. These instructions are summarized by standard symbols on each pallet.
The "DO NOT STACK" symbol indicates that pallets are packaged according to the maximum number of modules stackable vertically to avoid or reduce mechanical stress or damage. Stacking more than one pallet on top of another is strictly forbidden during shipment and storage. The "DO NOT EXPOSE TO ATMOSPHERIC AGENTS" symbol signifies that while each pallet is covered with transparent plastic to prevent temporary contact with water spray or atmospheric agents, this casing does not protect modules during prolonged exposure. In case of flooding, the pallet does not maintain the mechanical properties of the modules' weight, and stagnant water inside the frame could oxidize metal contacts, degrading electrical characteristics and causing damage. Therefore, pallets should be stored in a sheltered and dry place.
The "DO NOT OVERTURN THE PACKAGING" symbol emphasizes that packaging is designed for handling and storage with the arrow printed on the packaging always facing upwards. Failure to follow this direction can cause mechanical stress, damage, or breakage. The "RECYCLABLE" symbol indicates that most photovoltaic modules are recyclable and should not be disposed of in landfills without proper recycling methods. Following the EU Directive 2012/19/Ue, photovoltaic modules are classified as electronic waste. The "FRAGILE" symbol highlights that modules are manufactured with a glass front, making up approximately 70% of the total materials. Despite the aluminum frame, direct impacts to the glass or corners should be avoided. Flexing laminates, applying non-distributed loads, or scratching the exterior glass or backsheet should also be avoided.
When handling the pallet, utmost attention is required. Pallets should only be raised or moved with fork-lift trucks or hand pallet trucks fitted with forks of appropriate length for the pallet's size and weight. During handling and unpacking, verify that the package is positioned on a flat, non-deformed surface to prevent inclination that could damage the PV modules. FuturaSun does not assume responsibility for damage resulting from improper packaging management.
For unpacking, place the packaging on a stable, flat surface. Use a cutter to cut the plastic wrap or open the paper box, then remove the plastic wrap and the upper cover. Recover the flash list for record-keeping. Use a cutter to cut the straps, then remove the PV modules and their protective corners without causing damage. Partial packaging should not be stored, and once the strapping is removed, the packaging must not be moved.
