What is the principle of solar photovoltaic power generation!

Release time:

2024/08/06

① After the solar cell absorbs a certain amount of energy photons, the semiconductor produces a pair of electrons and holes, called "photogenerated carriers", the electrical polarity of the two is opposite, the electrons are negatively charged, and the holes are positively charged.

The oppositely polarized photogenerated carriers are separated by the electrostatic field generated by the semiconductor PN junction.

The photogenerated current-carrying electrons and holes are collected by the positive and negative electrodes of the solar cell, and generate current in the external circuit to obtain electrical energy.

How to optimize the photovoltaic solar power system?

Power inverter is the key electronic component of solar power generation system. In commercial applications, these components connect photovoltaic (PV) panels, batteries that store electrical energy, and a local power distribution system or utility grid.

Analysis of Solar Panel Capacity Design

The design of solar panel capacity is very important, and the capacity size Z finally reflects how much solar energy resources can be used. Solar panel capacity design is very simple, solar panel capacity mainly refers to the storage energy of solar panels.
