When the typhoon comes, or when the solar panels are installed on the water surface, there may be people worried that the module will be damaged and fall off, which will endanger the environment. Is the solar system so fragile?

Looking back at solar technology, in fact, the solar panels were quite vulnerable at first, and they were easy to fall off during the storm, so that the solar cells were damaged by water, and the solar system brackets were blown up, and the damage and compensation were difficult to estimate.

There are many reasons for the damage of the solar system. In addition to whether the bracket is reliable, the glass, aluminum frame and battery fragility of the solar panel are also important. The top-down structure of the solar panel is tempered glass, EVA polymer, solar cell. , EVA, back plate and aluminum frame, those storms and wind pressures with sand and gravel will cause the solar module to deform and crack, and with the arrival of the typhoon, "the object of the sky" is a strong enemy, easy to directly The solar panels are broken.

But with the rapid advancement of technology, solar panels are getting stronger and stronger. According to the National Renewable Energy Laboratory (NREL), only 0.1% of the 50,000 solar systems installed between 2009 and 2013 were damaged.

How to improve the resistance of the solar system, it requires a strong assembly technology and further strengthen the battery, the number of fixtures, the way to fix the module, the installation technology are the key points, such as Japan is often affected by typhoons every summer. As the climate changes, the chances of encountering more than 17 winds are unpredictable. Therefore, it is necessary to test the wind pressure to test the endurance of the module and the bracket, regardless of whether it is a module or a bracket, there will be the specifications.

At present, the ground type, roof type and water surface type panels can withstand all kinds of bad weather, but if the solar energy industry is to be flexible and light, and finally sewed on clothes, or integrated into portable equipment, the battery should be waterproof. After all, there is no strong tempered glass on the top to keep out the wind and rain. It can only rely on waterproof coating.

Previously, the University of Tokyo and the Institute of Physical Chemistry (RIKEN) jointly developed a solar cell that is both thin and waterproof, not only woven into clothes, but also thrown into the washing machine for cleaning.

The battery is made of a new semiconducting polymer, PNTz4T, which is coated with 1 micron thick poly-p-xylylene on both sides to resist water and moisture while allowing light to enter the battery. Solar energy produces about 7.86 milliwatts per square centimeter. After immersing in water for about 2 hours, the efficiency is only reduced by 5.4%. With the change of technology, scientists will create more and more durable solar cells in the future. Can be used in portable devices.
