How do solar panels work
The sun sends an infinite amount of energy to the earth. Best Solar panels convert some of that energy into electricity. Then you can read how it is possible.
Already in 1839, the French physicist Becquerel discovered that it is possible to generate electricity from sunlight. This is called the photo voltaic effect. Silicon (a semiconductor) is used for this in most systems. The sun's energy can release electrons in silicon. This creates tension in a solar cell. By changing several solar cells in succession in a solar panel, electricity can flow. To generate electricity, solar panels do not necessarily need direct sunlight. A solar cell also supplies
Electricity on a cloudy day.
Shadow: chain as strong as the weakest link
The circulating current is also the reason why the shadow reduces the performance of a set of solar panels. In the shaded cell, less current will flow, so the electrons will no longer walk. Therefore, in a system connected in series, the power supply is in fact as productive as its shaded link. To reduce this loss of performance, the panels have bypass diodes, which temporarily "skip" the shaded cell. When using the bypass diode, the performance of the solar panel system decreases mostly in Agricultural Solar Energy Panels. A system generally has three bypass diodes. A third of the system is turned off by bypass diode and has a third less performance. Then you can avoid the shadow!
If you really can't do the opposite and know in advance that there will be shade on the solar panels, you can use micrometers. In addition, each panel has its own inverter and a shaded panel does not guarantee that the entire system produces less. A system with micrometers is more expensive. Another solution for this situation is to link the MPP (maximum power point) trackers (also called 'power optimizer') to each separate panel. That is a small box that ensures that the current and voltage of the solar panel maintain an optimal relationship. This maximizes panel performance. Sometimes the power optimizer is integrated in the panel. They are usually cheaper than micrometers.
