With activity required under solar roofs, the leaking between solar panel gaps are to be solved. Here we listed some common solutions:

1. Using water proof glue.

This solution is the most commonly used and cheap solution for pitched solar roof system, but the appearance did not meet all customers needs.

2. Using Metal Deck as Waterproof Layer

This solution is commonly used in Australia Solar Carport solution. But the cost is expensive with a highly cost for logistic problem.

3. Water pipe between gaps. The magnesium alloy as water gap is widely used in Chinese Flat Solar Roof Mounting System.

It’s cost effective and a self-healing material.

4. A structure revolution for solar waterproof solution by changing the design.

This is the mostly good looking, easy installation and complete structure. As long as the capacity is over 200KW, this solution is recommended.
