Solar panelscan be connected in series. Can be powered by 3 solar panels. Two batteries connected in series do not simply constitute a series connection. The parallel connection is not much different from the theory. Battery resistance is related to the battery type, i.e. manufacturing materials and structure, and resistance is not constant during use.
The operating current has also reached more than 10A, and the efficiency of the switching power supply can reach about 75%. That is, a 100W solar panel produces 75W of power via the switching power supply if divided by. 6v, the maximum current value of 12.5a can be obtained.
The principle of energy production of solar panels;
A solar cell is a device that reacts to light and can convert light energy into electricity. It existsmany kinds of materials that can produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production are basically the same. Today, crystalline silicon is used as an example to describe the photovoltaic power production process. Crystalline P-type silicon is doped with phosphorus to obtain N-type silicon, forming a P-N junction.
When light irradiates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition and become free electrons. accumulate on both sides of the P-N junction to form a potential difference, when the external circuit is connected, under the action of this voltage, a current flowswill pass through the external circuit to produce a certain output power.
