“< H2 > what is the structure, composition and working principle of solar panels
The solar power generation system is composed of solar battery pack, solar controller and battery (pack). If the output power supply is AC 220V or 110V, it is also necessary to configure inverter. The functions of each part are: (1) solar panel: solar panel is the core part of solar power generation system and the most valuable part of solar power generation system. Its function is to convert the radiation capacity of the sun into electric energy, or send it to the battery for storage, or promote the load to work. The quality and cost of solar panels will directly determine the quality and cost of the whole system. （2） Solar controller: the function solar mounting solutions of solar controller is to control the working state of the whole system and protect the battery from overcharge and over discharge. In places with large temperature difference, the qualified controller shall also have the function of temperature compensation. Other additional functions such as optical control switch and time control switch shall be optional to the controller. （3） Storage battery: generally lead-acid battery. Nickel hydrogen battery, nickel cadmium battery or lithium battery can also be used in small and micro systems. Its function is to store the electric energy emitted by the solar panel when there is light and release it when needed. （4） Inverter: in many occasions, 220VAC and 110VAC AC power supply is required. Because the direct output of solar energy is generally 12VDC, 24VDC and 48VDC. In order to provide electric energy to 220VAC electrical appliances, it is necessary to convert the DC energy generated by the solar power generation system into AC energy, so DC-AC inverter is required. In some cases, when loads with multiple voltages need to be used, DC-DC inverter should also be used, such as converting 24VDC electric energy into 5VDC electric energy (note that it is not a simple step-down). The following factors need to be considered in the design of solar power generation system: Q7, quantity of system demand
Automatic light tracing device for solar panel
I haven’t tried how to do it, but I thought of a way to think. Real time steering of the sun according to its westward speed. The westward speed of the sun at different locations should be expressed by a function. As long as this function is calculated, it can be realized with the steering device and a control system
