Basic requirements of solar photovoltaic power generation system on energy storage battery

Celes

Photovoltaic storage battery is an indispensable component of solar photovoltaic power generation system to store energy, its main function is to store the electricity of the photovoltaic power generation system, and power supply for the load in the case of insufficient sunshine, night time and emergency. Commonly used energy storage batteries are lead-acid batteries, alkaline batteries, lithium batteries, which are used in different occasions or products, the most widely used is the lithium iron phosphate batteries, the fastest growing is the lithium batteries, there are mainly lithium iron phosphate batteries and ternary lithium batteries.

 

Solar power generation system has high cost, low conversion efficiency, strong variability with the environment, so the requirement of the energy storage is high. The service life of solar photovoltaic power generation system is generally 20 years, requiring the matching energy storage has a long service life, stable performance, higher energy efficiency, strong ability to adapt to the environment and other characteristics.

 

Lithium iron phosphate battery performance analysis:

 

Thunder Sky Winston Battery’s water-based lithium batteries add stable rare earth yttrium elements, and the use of large core stacked structure, with high security, non-explosive and non-flammable. At the same time, the monomer capacity is large, ranging from 50~10000Ah. Long service life, in the case of D0D80% can be used over 7000 times. Environmentally friendly and non-polluting, using water-based binder to replace PVDF. Working temperature range from -45~85C.

 

The voltage of each battery is about 3.2V, the specific energy is also more than 2 times that of lead-acid batteries, while the volume specific energy is 4 to 5 times that of lead-acid batteries, if the use of lithium iron phosphate batteries instead of lead-acid batteries used in the photovoltaic power generation system, you can greatly reduce the space occupied by the battery and reduce maintenance workload. In terms of photovoltaic energy storage efficiency, lithium iron phosphate battery has obvious advantages.
