The difference between peak power point components and tracking components is as follows:
1. Maximum Power Point: Tracking Maximum power point tracking is commonly used in wind turbines and photovoltaic systems. solar systems. The technology aims to obtain maximum power in every situation. It is mainly used in solar power generation, and the principle can be applied to power sources whose input power changes, light energy transmission, thermophotovoltaics, etc.
2. Light chasing component: Light chasing means the solar panel automatically follows the position of the sun to maximize absorption of solar energy. This technology is mainly used in solar power plants. Solar panels can automatically adjust their angles when the sun's position changes for guaranteedr maximum use of solar energy.
The relationship between the maximum output voltage of the power point and the open circuit voltage of solar cells under different lighting conditions
mppt is the tracking of the point maximum power point
Maximum power point tracking is a core technology in photovoltaic power generation systems. It refers to adjusting the output power of the photovoltaic generator according to different ambient temperatures, light intensity and other characteristics of the outside world, so that the photovoltaic is activated. The board always produces maximum power. Peak power point tracking is primarily used in solar power generation, but its principles can also be applied to power sources that vary in input power.
What does the voltage of 18 volts at pmax mean ?
If the light source is solar radiation and the solar radiation remains unchanged, the photoelectric conversion output voltage and current of the solar cell are dependent on the load. For example: if the power of the light source is 1000 W/M2 (solar radiation per square meter is 1 kilowatt), the output power of a monocrystalline silicon solar wafer with a total area of 1 square meter is 170 W, and the voltage is 170 W. The relationship between current and current is P=IV.
Why a DC circuit connected behind the solar panel can follow the maximum power point< /h3>
Passing voltage safety circuit. Maximum power Pmax, also known as maximum power point, is the maximum output power of the solar cell module, which is numerically equivalent to the product of maximum power point voltage Vmpp and power point currentmaximum Impp. According to the official website, the voltage at pmax is 18 volts, which means the safety voltage of the circuit is 18 volts. Since the three-phase alternating voltage will not cause various phenomena unless it falls to ground, the voltage passing through the circuit is a safe voltage and the voltage is less than 42 volts.
Maximum power tracking is a closed loop system. DCDC is a switching power supply. Output voltage and current are adjustable. Output power is equal to voltage times current. When the output current and voltage are adjusted, the voltage also changes. For example, if the output power increases after the current is adjusted down, it will think the adjustment is correct and then adjust it again until the output current and voltage are adjusted. he finds the maximum point.
