A high-voltage module rather than a high-current one
At the same 190 W, two panels can have very different electrical profiles. This one stands out with an open-circuit voltage of 43.82 V and a current at maximum power of only 5.25 A. That combination suits people who design their system around the chosen controller or inverter: a higher voltage reduces the current flowing in the cables, which makes it easier to choose their cross-section over long distances.
Use and configuration
The module connects through its MC4 connectors. Before any series or parallel assembly, add up the voltages and currents and compare them with the limits of the conversion device: in series, open-circuit voltages add together, and it is that sum which must not be exceeded, especially in cold, bright weather. Check the controller manufacturer’s manual to learn these ceilings. If you plan to add further modules later, note the figures now so that the final layout stays within the same limits.
For a private owner
A cabin away from the house, a garage, a solar pergola or a garden workshop: a higher voltage limits the thickness of the cables needed between the roof and the equipment room, and keeps the cable run easier to route through walls and conduits.
For a professional
Agricultural equipment, measuring stations or outdoor lighting can benefit from this profile when the distance to the controller is significant. Installers who prepare several identical lines will find the data easy to compare from one string to another.
Materials and dimensions
The panel combines monocrystalline cells with a 19.31% efficiency, tempered glass and an aluminium frame. It measures 1396 x 705 x 35 mm and weighs 10.6 kg. Its stated weather protection makes it suitable for outdoor exposure, and the rigid frame keeps the glass flat once the panel is bolted to its support.
What this model offers
- Reduced current, so less demanding wiring.
- Mid-size format, simple to fix on rails.
- Cell efficiency of 19.31%.

Wiring precautions
A higher voltage calls for extra care when handling: insulate the ends of any unconnected cables, work away from moisture and never unplug a connector under load. Any connection to a household distribution board is reserved for a qualified installer. Do not confuse this model with the same-format version that carries a higher current: their characteristics are not interchangeable, and mixing them in one string could upset the balance of the system.
Care and storage
Remove leaves and dust with a soft cloth, clean water and, if needed, a soft-bristled brush. During storage, keep it dry and away from impacts, and stack modules with protective spacers. Inspect the connectors for dirt before each reconnection.
