What are the advantages of DualSun FLASH and SPRING Shingle panels?
The DualSun FLASH Shingle Black and SPRING Shingle Black solar panels are equipped with so-called "Shingle" cells.
This next-generation cell technology brings a multitude of benefits to SPRING and FLASH panels.
- Better overall module performance by reducing hot spots and optimizing the active surface
- More sustainable by reducing internal mechanical stress on the module
- Sustainability certified by the TÜV control office and low impact of extreme conditions
- Shingle cell technology allows better pressure absorption on the panel compared to traditional monocrystalline photovoltaic cells.
Shingle cells are less affected by micro-cracks, so the decrease in yield over time is lower

Better overall module performance thanks to low string intensity
The cells of the FLASH and SPRING Shingle panels have an intensity 5 times lower than conventional cells. This feature gives these panels a better performance than a conventional panel.

P= R x I²: The Joule effect losses are therefore significantly lower thanks to Shingle technology
This leads to an average operating temperature of about -5°C on the Shingle modules. Performance is improved.
More durable solar panels thanks to the reduction of mechanical stress in the module
The FLASH and SPRING panels with Shingle technology incorporate an innovative cell interconnection process.
The low temperature and flexibility of the interconnection process remove the internal mechanical stress usually present in modules with high-temperature interconnections.
Standard photovoltaic technology
On standard panels, interconnections are done at high temperatures (250-300°C).

Shingle cells are evenly affected by micro-cracks
For a variety of reasons, solar cells can undergo micro-cracks.
For a standard full cell or half-cut cell module that has a micro-crack, a portion of the cell becomes isolated, the current through this area no longer circulates, which affects the efficiency and performance of the panel.
In the case of a FLASH or SPRING panel with Shingle cells, the continuity of the inter-connection does not affect the flow of electrons and thus the performance of the module, even in case of micro-cracks.
Shingle technology does not take the pressure, it absorbs it

Standard photovoltaic technology Standard photovoltaic technologies concentrate bending stress on interconnection points under pressure, so module performance decreases. |
Low-temperature static mechanical load
Shingle technology is more resistant to low-temperature mechanical loads than conventional full cell or half-cut modules.
