Decision guide
Which type is right for me?
| Situation | Recommendation |
|---|---|
| Small roof, maximum output | Monocrystalline |
| Large roof, small budget | Polycrystalline |
| Flat roof, snow region | Bifacial |
| Façade or unconventional roof | Thin-film |
| Standard single-family home Switzerland | Monocrystalline |

Frequently Asked Questions
Which solar panels are most popular in Switzerland?+
Monocrystalline panels are by far the most commonly installed in Switzerland. They offer the best efficiency even in overcast conditions and are ideal for the Swiss climate.
What is the difference between monocrystalline and polycrystalline?+
Monocrystalline panels have higher efficiency and are more compact, but cost a bit more. Polycrystalline panels are cheaper, but need more space for the same output.
Are bifacial panels worth it for a normal single-family home?+
On a normal pitched roof, the additional production from the rear side is small. Bifacial panels are most worthwhile on flat roofs or in snow regions.
Which panels last the longest?+
All high-quality crystalline panels have a performance warranty of 25–30 years. The choice of manufacturer is often more important than the technology.
Can I combine different panel types on the same roof?+
This is technically possible, but not recommended in practice. Different panels have different electrical characteristics, which can reduce system performance.
Which panel type best suits the Swiss climate?+
Monocrystalline panels are the best choice for the Swiss climate — they deliver good output even in overcast conditions and with diffuse light, and are robust against snow and cold.
