Sales and delivery conditions

⚠️ For orders requiring delivery, the panels are sold exclusively by full pallet of 31 units.

For orders collected directly from the SolarTech warehouse, the panels can also be purchased individually.

The Osda 620W N-Type Bifacial Photovoltaic Panel is designed for photovoltaic installations requiring high power output while making efficient use of the available installation area. The model uses 132 monocrystalline N-Type cells and achieves an efficiency of 22.96%.

Bifacial technology enables the panel to capture light through both its front and rear sides. When installed above a light-reflective surface, such as light-coloured gravel, a white membrane, or concrete, the panel can also use the solar radiation reaching its rear side.

Under the BNPI conditions specified in the datasheet, with front-side irradiance of 1,000W/m² and rear-side irradiance of 135W/m², the resulting output can reach 687W. This value represents a standardised bifacial testing condition and is not the panel’s rated STC output.

The dual-glass construction uses 2mm tempered front glass with an anti-reflective coating and 2mm rear glass. This structure provides protection for the cells and is suitable for residential, commercial, and industrial photovoltaic installations.

Advantages

More energy from the same area

The 620W output and 22.96% efficiency enable the development of photovoltaic installations with a high power density.

Power generation on both sides

The rear side can convert reflected light into electricity when the installation conditions and the surface beneath the panel support bifacial energy capture.

Good performance at high temperatures

The Pmax temperature coefficient of -0.290%/°C limits power losses when the cell temperature increases.

Improved low-light performance

N-Type technology contributes to energy production during periods of lower irradiance, such as in the morning and evening.

Robust construction

The dual-glass structure, anodised aluminium frame, and IP68 junction box protect the module’s components under normal installation and operating conditions.

Recommended applications

Residential photovoltaic systems
Commercial and industrial buildings
Rooftop installations
Ground-mounted systems
Photovoltaic carports
Projects where reflected light can be captured through the rear side

Technical warning

The additional output generated through the rear side depends on the surface beneath the panel, its reflectivity, the installation height and angle, the spacing between rows, and the irradiance conditions.

String sizing must take into account the panel’s voltage and current ratings, the inverter’s limits, and the minimum and maximum temperatures at the installation site.

Installation, configuration, and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and applicable regulations.
