Generally, the optimal angle is equal to your latitude plus 15-20 degrees in the summer and minus 15-20 degrees in the winter. 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. . This fact causes the winters to be cold due to lower solar radiation and summers to be hot as the solar radiation increases. To make the best out of the available solar radiation, compensating the tilt angle of your panels according to the different positions of the sun will optimize power output. . When the sun is lower in the sky, solar panels need a greater tilt angle to receive direct sunlight. When the sun is higher, panels require less tilt.
