     Solar mountings: why choose ETN certification?

✅ Compliance with French standards

ETN certification guarantees that the mountings meet CSTB requirements and current safety standards, for reliable and durable installation.

✅ Resistance to climatic stress

Strong winds, snow, thermal expansion... ETN-certified mountings are designed to withstand extreme conditions and keep solar panels in place.

✅ Preserved warranties and insurance coverage

Non-certified mountings can jeopardize the equipment warranty and complicate claims in case of damage. ETN ensures compliance with insurer expectations.

✅ Preserved performance thanks to optimal mounting

A poorly mounted panel can shift or become misaligned, leading to a loss of energy production. With ETN-certified mountings, the installation remains stable and efficient.
