Before understanding the question of "how much does the best tilt angle of Solar Panel Adjustable Tilt Mount affect the power generation", we must first understand the direction of the solar panel installation, otherwise you are at the best angle but the direction is completely opposite, and this kind of power generation is actually not very useful. Take the solar panel installed on the roof as an example. The orientation of the house generally determines how much sun you can get in a day, which also determines how much sun the solar panel can get.
The correct way to judge due south and due north is: due north and due south face the axis of the earth, not aligned with the earth's magnetic poles. For people north of the equator, the best direction for solar panels is south, while families in the southern hemisphere place solar panels on roofs facing north. By changing the Solar Panel Adjustable Tilt Mount according to the true south and azimuth - the angle of the sun relative to the true north and south - you can get the best direction for the solar panel.
After determining the orientation of the solar panel, let's adjust the best angle of the Solar Panel Adjustable Tilt Mount. What is the best tilt angle? The best angle for solar panels is to get the most direct, vertical light to the panels. If your solar panels are perpendicular to the ground, they will have a 90-degree tilt. To collect solar energy more efficiently, the angle of the solar panels should be as close to the sun as possible. Photovoltaic energy is generated when the angle of sunlight hitting the surface of the panel (the "incident angle") is small, or when the light hits the panel as close to vertical as possible.
So how do you calculate the best tilt angle for the Solar Panel Adjustable Tilt Mount? To calculate the best tilt angle, you need the local longitude and latitude to determine the altitude and azimuth of the sun at each time, and you need annual radiation data, preferably multi-year average annual radiation data to determine the characteristics of local solar radiation. Software such as PVsyst can be used to calculate the best tilt angle quickly and easily. The best angle will be affected by direction, latitude, and altitude, which should also be taken into account at that time. The power generation of solar panels will differ by about 20% between the best angle and the non-optimal angle.
