Frequently Asked Questions
What does the bifacial half-cut technology of this module mean?
Half-cut means that the 132 monocrystalline cells have been cut in half. This reduces internal losses and makes the module less sensitive to partial shading. Bifacial means that the rear side also converts light into electricity: reflections from the ground or roof further increase the total yield.
Why is a power tolerance of 0/+3% an advantage?
The purely positive tolerance guarantees that every module delivers at least the stated 620 Wp – never less. In practice, many modules even perform slightly better, which further secures the yield of your system.
How much electricity does the module generate per year in Austria?
A 620 Wp module in Austria delivers around 560 to 680 kWh per year, depending on location and orientation. At an electricity price of 25 ct/kWh, this corresponds to a saving of approximately €140 to €170 annually – the bifacial design can further increase this value on bright surfaces.
How many modules do I need for my home?
For a typical annual consumption of 4500 to 5500 kWh, about 10 to 13 of these 620 Wp modules are advisable. This results in a system output of around 6 to 8 kWp and covers a large part of your own electricity needs.
Is the module suitable for alpine conditions?
Yes. The stable 30 mm high aluminum frame is designed for high snow and wind loads, such as those occurring in mountainous and high-altitude regions. Monocrystalline modules of this class also operate reliably at low temperatures and even deliver particularly good yields in cold, clear high-altitude air.
