No matter how set, the solar panel will tilt (the tilt angle is the right angle between the solar panel surface and the sunlight) to face the sun. That is because their conversion is to obtain energy from the sun. Therefore, whether on the roof or on the ground, solar panels need to be exposed as much as possible to absorb the sun’s rays.
There is no doubt that solar panels are more efficient at high altitudes. In addition, unlike sea level, they are more likely to be exposed to solar radiation. They can better convert energy into electrical energy for our daily activities.
Is solar energy more effective in high altitude areas?
Solar panel systems are one of the highest sources of clean energy power generation, but usually they are installed on the sea level. Some people may want to know whether solar energy is more effective in high altitude areas? The basic reasoning will make you think that it should be because it is closer to the sun, but let us understand more. The sun emits electromagnetic radiation, also known as solar radiation, and the cells in the solar panel absorb these radiation to generate energy. However, sometimes this radiation will be blocked by dust, dirt or snow and other factors, thus preventing solar panels from making full use of them. On the other hand, there are fewer atmospheric barriers and obstacles in high-altitude areas, and they work better in high-altitude areas.
In general, increased solar radiation exposure will lead to an increase in the voltage output generated, thus inadvertently improving efficiency. This is very likely because at higher altitudes, we get more direct radiation and less diffuse radiation.
How to improve the performance of solar panels at high altitude?
To understand how to improve the performance of solar panels at high altitude, we must understand what hinders the full performance of ground solar panels. So, let’s understand why solar panels can’t give full play to their maximum performance on the ground.
1. Weather
Several weather conditions have different effects on the performance of solar panels. In sunny days, contrary to the popular view, when the surrounding is too hot and the temperature is too high, the performance of solar panels will be greatly reduced. They depend on the amount of sunlight absorbed by the panels, not the temperature around them. On the other hand, solar panels will not generate electricity during rain, snow and hail storms.
2. Shadow
Any shadow on the solar panel will damage the efficiency of the panel, which will lead to the reduction of system output. The shadow is not necessarily a cloudy sky. It may be something that blocks solar panels from the sun. Therefore, when you want to install a solar panel system, first of all, you should ensure that there is nothing blocking the solar PV module in this area. For example, trees, satellite antennas, tall buildings, etc. should not block your solar panels.
3. Low maintenance
Over time, dust, dirt or debris may accumulate on the solar panels. Therefore, it is assumed that the solar panels are not regularly cleaned or maintained. In this case, the efficiency of solar panels may decline.
In short, we have seen the factors that affect the solar panels at low altitudes and make them unable to maximize their performance. The performance of solar panels at high altitudes will be improved.
conclusion
Solar panels are more efficient in high altitude areas, because solar ultraviolet rays will increase with the increase of altitude in the atmosphere, which is due to the reduction of air molecules, emissions, etc., and solar panels receive more sunlight.
