Solar battery play an important role in solar energy systems
Definition and Importance
solar battery are the core components of solar energy systems. They are devices specially designed to store the electricity generated by solar energy systems.
In solar energy systems, solar batteries play a vital role. They ensure that the system can provide electricity stably and continuously. They are of great significance for making full use of solar energy and reducing dependence on traditional power grids.
Solar eryunctions:
Storing electricity: storing excess electricity generated by solar panels during the day.
Stable power supply: releasing electricity at night or on cloudy days to keep the system running stably.
Emergency backup: providing power for key equipment (water treatment equipment) when the power grid is out of power.
Principle:
Charging: When solar panels generate electricity, electricity is stored in batteries through controllers and converted into chemical energy.
Discharging: When electricity is needed, batteries convert chemical energy into electricity for equipment use.
Features:
High efficiency: reducing energy waste and making full use of solar energy.
Durable: can be charged and discharged repeatedly, with a long life.
Safety and environmental protection: leak-proof, explosion-proof, and recyclable materials.

When designing a solar energy system, you need to determine the following system configuration information:
- Local annual average sunshine duration.
- Available space for installing solar panels.
- Total power of AC loads; load operating time, rainy day requirements.
- Backup time in hours.
