Will Solar Panels Be Damaged When Exposed to Rain?

Solar panels are gaining popularity as an environmentally friendly energy source that can reduce dependence on conventional electricity. However, many people still wonder, can solar panels be damaged if exposed to rain? Since solar panels are installed outdoors and exposed to various weather conditions, it is important to understand how rain can affect their performance.

This article will answer your concerns regarding this and steps to maintain the durability of solar panels. Let’s move on to the explanation.

Solar Panels Will Not Be Damaged When Exposed to Rain

Of course, solar panel manufacturers have thought about this. They have designed solar panels to withstand various weather conditions such as rain. One way to protect the main components of solar panels is to use tempered glass as the outermost material.

Tempered glass Protects solar cells from impacts, dust, rain, and extreme weather changes. Tempered glass has high resistance to pressure and can reduce light reflection to increase the efficiency of sunlight absorption.

In general, solar panels are equipped with IP (Ingress Protection) certification, which is a certification that measures the strength and durability of the exterior of electronic equipment. Solar panels that are equipped with IP67 certification indicate that the solar panels can withstand water up to one meter in 30 minutes and are dustproof. Solar panels with IP67 are guaranteed safe for outdoor use.

Likewise, solar panels from Nali New Energy Technology have guaranteed quality including IP67 certification. You can check the product list here.

Benefits of Rain for Solar Panels

Instead of causing damage, in conditions where solar panels are well-maintained, rain actually brings benefits.

Cleaning the Panel Surface
Rain can help remove dust, dirt, and other particles that stick to the panel surface. Clean panels will be more effective in absorbing sunlight and increasing the efficiency of energy production.

Cooling Solar Panels
Solar panels work better in lower temperatures. Rain can help cool panels that have previously been exposed to the sun’s heat, reducing the risk of overheating and maintaining optimal performance.

How to Keep Solar Panels Optimal in Rainy Conditions

Although solar panels are IP67 certified, without proper handling and maintenance, there is still a risk of damage in rainy conditions. Therefore, we must take several actions to prevent this.

  1. Conduct routine checks by checking the physical condition of the panel periodically to ensure there are no cracks, leaks, or damaged seals. Also make sure no water enters the electrical components.
  2. Clean the panel if necessary. Although rain can clean the panel, in some cases dirt can still remain. If necessary, clean the panel using clean water and a soft cloth to avoid scratching the surface.
  3. Ensure the installation is done properly. Panel installation is done correctly and using quality materials to prevent leaks or damage due to heavy rain. Professional installation will reduce the risk of technical problems in the future.
  4. Use Surge Protector. o avoid damage from lightning or voltage spikes, use a surge protector installed on the solar panel system. This will help protect the inverter and other electrical components from external interference.

Conclusion

Solar panels are designed to withstand a variety of weather conditions, including rain. In fact, rain can help improve the efficiency of the panels by cleaning their surfaces of dirt. However, it is still important to perform regular inspections and maintenance to keep the panels working optimally. With proper installation and proper protection, solar panels can be a reliable and long-lasting energy solution, even in extreme weather conditions.
