The tilt angle of solar panels, solar folding packs are all inconsistent, depending on where you are in the world (latitude, northern and southern hemispheres), when solar panels/solar and pv wire folding packs are exposed to direct sunlight, their ability to output.
The sun moves across the sky, getting lower or higher depending on the time of day and season. Therefore, the ideal angle is never fixed. In order to reach the solar panel with the most light of the day, it is necessary to determine the direction the solar panel faces and calculate the optimal tilt angle. This will depend on:
Place of residence (latitudinal location, northern and southern hemispheres).
At what time of year, solar energy is most needed and the intensity of light is greatest.
Calculate the optimal solar panel angle
As a rule of thumb, solar panels should be more vertical in winter to get most of the low winter sun and more tilted in summer to maximize output. Here are two simple ways to calculate the tilt angle of a solar panel based on latitude.
Calculation Method 1
The optimal tilt angle is calculated by adding 15 degrees to your latitude in winter and subtracting 15 degrees from your latitude in summer. For example, if your latitude is 50°, the optimal tilt angle for your solar panels in winter will be 50+ 15 = 55°. On the other hand, the best tilt angle in summer is 50-15 = 35°.
Calculation Method 2
If you're near the equator, you can get the best angle by laying the panels flat on the ground.
Calculation Method 3
This is an improvement over the general approach and can provide better results. In this method, the optimal tilt angle of the solar panel in winter is calculated by multiplying the latitude by 0.9 and adding 29°. In the above example of 34° latitude, the inclination angle would be (34 * 0.9) + 29 = 59.6°. This angle is 10° steeper than the usual method, but makes very effective use of the midday sun, which is the hottest of the short winter days. In summer, the tilt Angle was calculated by multiplying latitude by 0.9 and subtracting 23.5°. In the example above, this angle is (34 * 0.9) -- 23.5 = 7.1°. To get the best tilt in spring and fall, subtract 2.5° from the latitude.
