The side-view diagram shows your panel at different tilt angles, with summer and winter sun paths arcing overhead. A correctly tilted system can improve efficiency by 5–10% annuall y, reducing payback time and boosting long-term savings. Start by entering your location in the search box. For this reason, unless we install a solar tracker, we must look. . During the spring the best angle is 45°, and during the summer when the sun is high in the sky, it's best to have a low tilt at 20°! What angle for solar panels should be chosen to maximize the production all year long? The aim is to produce more heat in the winter and less heat in the summer. . This solar angle calculator tells you the optimum angle to get the best out of your system.
