  2. With amorphous silicon cells: They are recognized by their brown colour and their performance is low, so they are not very suitable for use in motorhomes. 
  3. With polycrystalline silicon cells: They are recognized by their blue colour, and their performance is low when the sun shines weakly.

However, we recommend that you choose a solar panel with a higher power than what you think you might need so that you do not have future problems.
