Feature: 1. 【Premium Material】: This solar angle guide is crafted from premium materials, ensuring long durability under harsh weather conditions. Its robust construction guarantees superior performance and longevity. 2. 【Easy Operation】: Designed for simplicity, this angle guide securely fastens to portable solar panels of any thickness without causing scratches, thereby protecting and prolonging the lifespan of your panels. 3. 【Maximize Solar Efficiency】: Precisely measure the verticality of your solar panels to optimize the focusing angle of light. Maximize the energy of your solar system with this angle guide. It helps you find the perfect working angle for your solar panels, accelerating charging times and enhancing energy production. 4. 【Working Principle】: Utilizing its transparent design, you can lineup the sunshadow to the center of the solar angle guide. Adjust your solar panel to achieve the maximum tilt angle for superior performance. The closer the light incidence angle approaches 90°, the greater the solar energy absorption and the quicker the charging process. 5. 【Wide Applications】: Effortlessly attain accurate solar alignment with this versatile angle guide. Suitable for foldable portable solar panels or mounting brackets, it is an indispensable calibration tool that\u0027s easy to install and detach. Save time and effort, ensuring precise panel orientation. Specification: This solar angle guide can precisely measure the verticality of your solar panels to optimize the focusing angle of light.
