【 SOLAR ANGLE GUIDE 】The solar angle guide is an accessory that helps to keep the solar panel at a 90° angle to the sun and focus the sun's rays on the surface of the solar panel.
【 HOW TO USE 】Insert or clip the solar angle guide to the edge of the solar panel. When the sun shines on it, the transparent cover dots will project a circular shape on the panel surface. Adjust the angle of the solar panel. The closer the projected circles to the center, the closer the angle of the sunlight will be to 90°, and the higher the solar panel's efficiency will be.
