15-40 degrees — the best angle for solar panels in the US Want to know the perfect angle for your solar panels? It's easy! Just find your latitude. In winter, tilt them 15 degrees more. A correctly tilted system can improve efficiency by 5–10% annuall y, reducing payback time and boosting long-term savings. In this guide, we'll break down. . Our solar panel angle calculator takes the guesswork out of panel positioning, suggesting panel tilt angles based on your location's latitude and your willingness to reposition based on the sun's seasonal dance across the sky. Solar panel. . 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. 6º, versus New Orleans at 26. Check out our table below for more examples of ideal tilt angles by city.
