Due to the direction of the roof side, pointing to WSW, Energossa chose monocrystalline cells, who are more effective than polycrystalline for diffuse light.
We had enough place (and money) to install 20 panels 'aleo solar S17/195'. The manufacturer's homepage can be found here.
Technical details of the panel:
- at least 195 Wp (verified) per panel: the test data of my panels
- 3 % tolerance
- 50 monocrystalline wafers
- 20 years warranty (20 years on 80 % of the power output, 10 years on 90 % of the power output)
- Data sheet overview (my panel is a 195 Wp panel, thus not exactly the ones in the offered data sheets):
