Flexible Modules?

Most of the photovoltaic modules sold for self-consumption are rigid. However, for certain types of installations, it is worth considering the use of flexible modules.

There are mainly two types of flexible solar panels: thin-film solar panels, where the photovoltaic material is printed on a flexible surface, and crystalline silicon panels with very thin silicon layers that offer some flexibility. Currently, crystalline silicon panels are the most common.

Advantages and disadvantages of flexible modules:

✅ Lightweight: A flexible monocrystalline module of 380W can weigh around 5-6 kg compared to the 20 kg of a similar standard module, making them a good option for roofs that cannot support heavy loads.

✅ Adaptability: Flexible modules better adapt to curved roofs.

❌ Lower efficiency: In thin-film flexible modules, the efficiency is around 8-14%. For flexible monocrystalline modules, the efficiency is similar to that of rigid modules, between 15% and 24%.

❌ Temperature losses: When adhered to the roof, ventilation is poorer, leading to greater temperature-related losses.

❌ Lower durability: They are more exposed to the elements and extreme weather conditions such as hail.
