The inclination angles of solar panels and solar folding bags are inconsistent, which is based on the position of your world (latitude, northern and southern hemispheres) and their output ability when the solar panels / solar folding bags are directly exposed to the sun.
The sun moves in the sky. According to the time of day and season, the sun will become lower or higher. Therefore, the ideal angle will never be fixed. In order to reach the solar panel with the strongest light in a day, it is necessary to determine the direction that the solar panel should face and calculate the best tilt angle. This will depend on:
Place of residence (latitude, northern and southern hemisphere).
When do you need solar energy most in a year, and the light intensity is the greatest.
Calculate the best solar panel angle
According to experience, solar panels should be more vertical in winter to get most of the low sun in winter, and more inclined in summer to maximize output. Here are two simple ways to calculate the tilt angle of solar panels based on latitude.
Calculation method I
The best inclination angle is calculated by increasing your latitude by 15 degrees in winter and subtracting 15 degrees from your latitude in summer. For example, if your latitude is 50 °, the best tilt angle of your solar panel in winter will be 50+ 15 = 55 °. On the other hand, the best tilt angle in summer is 50 – 15 = 35 °.
Calculation method II
If it is close to the equator, then the best tilt angle can be obtained by placing the solar panel flat on the ground.
Calculation method III
This is an improvement on the general method and can provide better results. In this method, the optimal tilt angle of solar panels in winter is calculated by multiplying the latitude by 0.9 plus 29 °. In the above example with a latitude of 34 °, the inclination angle will be (34 * 0.9) + 29 = 59.6 °. This angle is 10 ° steeper than the general method, but it makes very effective use of the noon sun, which is the hottest in the short winter. In summer, the inclination angle is calculated by multiplying the latitude by 0.9 and subtracting 23.5 °. In the above example, this angle is (34 * 0.9) – 23.5 = 7.1 °. To obtain the best tilt angle in spring and autumn, subtract 2.5 ° from the latitude.
