How the new lithium solar energy storage technology to enhance the efficiency of the PV system

University of Southampton and REA Psystems collaborative research discovered a new type of lithium battery as the solar energy storage device PV systems, solar energy storage efficiency can be increased to 95%, can greatly reduce the cost of solar power.

Most current PV system also uses lead-acid batteries as the solar backup generator device, there is far, lithium iron phosphate battery replacement can give full play to its advantages, including improved storage efficiency, long life, low unit cost, and so on. The type lithium is used as an solar energy storage device, the energy efficiency can be increased to 95%, far more than 80% of the traditional lead-acid batteries, and has 1,600 charge-discharge life.

Lead-acid battery of solar generator energy storage device is used in most traditional photovoltaic systems. However, as the energy storage device, lithium batteries, especially the LiFePO4 batteries we use, have more favorable characteristics.

Collect these data, it is necessary to connect the lithium iron phosphate battery and off grid Solar System，PV systems installed in the building at the University of use provided by the REA Psystems specially designed battery management system. someone added, "Research shows that 95% of the lithium battery energy efficiency, and the most commonly used lead-acid batteries, only about 80 percent, while the lithium battery lighter and has a longer use than lead-acid batteries life. charge and discharge times can reach 1600 cycles, which means they do not need regular replacement.” 

Although before commercial photovoltaic systems, batteries need further testing. But studies have shown that, LiFePO4 battery is expected to improve the efficiency of solar power kit off grid generation system, and helps reduce installation and maintenance costs.

For a variety of energy sources (renewable or non-renewable), solar energy storage devices, such as batteries, plays an important role in terms of energy solar backup generator use, with the traditional lead compared acid batteries, LiFePO4 battery has a higher efficiency, longer life, lighter weight, cost less. we expect to be able to see such batteries are widely used in photovoltaic systems and other renewable energy off grid solar systems.
