Solar power panels use low-iron glass to protect the panels. If the external glass layer fogs up because of temperature differences, solar power generation efficiency is affected. Ray Materials anti-fog coating is super-hydrophilic in nature, reducing the contact angle and preventing fogging. Such super-hydrophilic properties form a water layer and allow the panels to self-clean when it rains, preventing reduced output from panel surface pollution.
Solar panel output decreases with higher temperatures. Ray Materials anti-fog coating is not visible to the naked eye, but a water layer is formed to prevent fogging. Natural light evaporates this layer and reduces the temperature of the panels, helping to increase output.
