Traditional solar panels

Traditional solar panels are rigid panels generally used for roof installation. Depending on your priorities, you can choose between: amorphous (lower surface yield but better production in cloudy weather), polycrystalline (excellent power/price ratio) or monocrystalline (the highest yield, with attractive black cells). To quickly estimate the number of panels and the output based on your orientation and inclination, use our simulation tool.

  • Priority on efficiency/aesthetics: go for monocrystalline (black cells).
  • Priority on budget: polycrystalline offers a very good power/price ratio.
  • Priority: weather conditions (overcast skies):amorphous panels perform better in grey weather (but less per square metre).
  • Typical use: roof installation (rigid panels).

FAQ – Traditional solar panels

1. What is the difference between monocrystalline, polycrystalline and amorphous panels? +
The page distinguishes: monocrystalline (highest efficiency, black cells), polycrystalline (excellent power-to-price ratio) and amorphous (better output in cloudy weather, but lower efficiency per surface area).
2. Are traditional solar panels suitable for roof installation? +
Yes: these are rigid panels generally used for roof mounting.
3. How can I estimate how many panels I need for my project? +
Use a simulation tool to estimate the number of panels and production based on your orientation and tilt, such as the Solar Simulator.
4. Which panel type should I choose if budget is my priority? +
According to the page, polycrystalline is an option with a very good power-to-price ratio.
5. Which panel type performs better in cloudy weather? +
The page indicates that amorphous panels perform better in cloudy weather, even though their efficiency per surface area is lower.
