Frequently asked questions
What does monocrystalline half-cut technology mean for this module?
The 132 monocrystalline cells are halved (half-cut), meaning only half the current flows per cell. This reduces resistance losses, increases efficiency to 23.3%, and improves performance in partial shading. The 16 busbars collect the generated current with particularly low losses.
What characterizes the bifacial glass-glass construction?
Instead of a plastic backsheet, the cell is situated between two 2.0 mm thick glass panes. This makes the module mechanically stable and durable. As a bifacial module, it also utilizes scattered and reflected light on the back, thus generating additional yield with suitable mounting.
How much electricity does the module generate per year in Austria?
A 630 Wp module in Austria delivers approximately 600 to 750 kWh per year, depending on orientation and location. At an electricity price of 25 cents/kWh, this corresponds to a saving of about 150 to 190 euros annually per module - the bifacial rear-side yield can further increase this value.
How many modules do I need for my home?
For an annual consumption of 4500 to 5500 kWh, around 8 to 12 modules of this type are advisable. This results in a system output of approximately 5 to 7.5 kWp. The exact number depends on the roof area, orientation, and desired self-consumption rate.
Is the module suitable for alpine locations?
Yes. The module is tested for snow loads up to 5400 Pa and wind loads up to 2400 Pa, making it suitable for snowy regions. The glass-glass construction is robust against hail and temperature changes, and the low temperature coefficient of -0.29 %/°C ensures stable yields even in cold conditions.
