Solar power generation principle and technical application
1. Principle of solar power generation: (I) How do solar cells work? The working principle of crystalline silicon n/p-type solar cells: When p-type semiconductors and n-type semiconductors are tightly combined and connected into one piece, a p-n junction is formed at the interface between the two. When the photovoltaic cell is irradiated by sunlight, positive and negative charges accumulate on both sides of the p-n junction, generating a photoelectric voltage and forming a built-in electric...
Things to note when solar energy storage power supply is not used for a long time.
If the solar energy storage power supply system is not used for a long time, the following points should be noted: 1. Keep the charging state: In the case of long-term non-use, in order to keep the energy storage battery charged, it can be charged regularly. It is recommended to charge it every once in a while, and the time interval should not exceed 3 months. 2. Turn off the load: In the case of long-term non-use, all load devices need to be turned off to prevent battery power loss. 3. Prevent...

Is the solar industry ready for a wave of retirements?
In the global rush to deploy solar PV as quickly as possible to reduce carbon emissions, the importance of dealing with projects at the end-of-life stage, 20-40 years later, is often underestimated. Decommissioning a PV system is essentially a reverse installation process, typically involving the removal of the PV array and all balance of system (BOS) equipment, and returning the land or infrastructure to its original state or for a new use. However, there is limited research on the...
