One: How to handle water leakage in the sunshade and rain shelter.
1、 Waterproof silicone sealant can be used to fill the gaps in solar panels. When repairing, first remove any existing sealant. Then, cut the sealant and create a large opening, applying it to the edges of the gap. During application, press the sealant evenly with your finger to achieve a better repair.
2. Alternatively, you can use the method of installing top corner profiles to cover the gaps between the roof and the wall, which can prevent water leakage from the cracks in the solar panels. Since waterproof coatings may also detach over time, installing top corner profiles is a more practical approach.
3. Alternatively, foam sealant can be injected at the junction between the awning and the wall, followed by a layer of silicone sealant in the gaps. This can also help prevent water leakage.
II. How to prevent rainwater leakage from solar panel canopies
1. The requirements for Durabond boards and sealing glues are very strict. Many customers are unaware of these requirements and apply acid-alkaline glues, which are incompatible with Durabond boards, leading to water leakage. Another factor is the use of substandard sealing glues. The market for sealing glues is complex, and many customers are unsure which glue provides the best sealing performance. Therefore, when installing solar panel canopies, it is essential to select high-quality, suitable sealing glue materials.
2、We understand that PC board is characterized by its thermal expansion and contraction properties, so it is necessary to reserve space between the boards to accommodate this expansion and contraction. This will help prevent water leakage.
3. Due to its low density and light weight, Resist Board is easy to transport and install, being only 1/12 to 1/15 the weight of glass. However, due to its light weight, it is necessary to consider wind loads or other external forces that may cause deformation or cracking of the Resist Board during installation, which could lead to water leakage.
4. Before sealing the solar panels, ensure that all edges are smooth and that all dust and debris inside the grooves are removed.
