A battery energy storage system is a new type of renewable energy storage system that stores solar energy in batteries when there is no sun. In this guide, learn about battery storage systems and how they can provide sustainable energy for agriculture.
What are the current market trends for solar energy storage systems?
The solar industry took off in 2008. With the proliferation of residential solar panels and government support for renewable energy, more and more people are turning to solar energy. The market for battery energy storage systems is expanding rapidly, with solar energy storage becoming a very important aspect of the entire market. According to a Navigant Research report,“The global market for battery energy storage systems for renewable energy generation is expected to grow exponentially over the next decade.”
Comparison of two solar battery systems: lead-acid and lithium-ion batteries
Lead Acid Batteries: Lead contains water, sulfuric acid and an electrolyte. When the battery is charged, the lead is oxidized, turning the lead dioxide into lead sulfate. The result is a reduced battery size, which means it can be stored anywhere with less space.
Lithium-ion battery: Lithium ions move from one electrode to the other through a circuit consisting of two electrodes and an electrolyte. This type of battery will have high energy density, resulting in higher voltage and lighter weight than lead-acid batteries. What's more, lithium-ion batteries are truly green because they don't contain harmful elements like mercury, lead, and cadmium. Therefore, compared with traditional lead-acid batteries, lithium-ion batteries are more environmentally friendly.
Battery type is an important factor when looking for a battery system for your solar electric system. Lead-acid batteries are inexpensive and plentiful. Lithium-ion batteries, however, have a higher energy density and longer life because they can be charged faster than lead-acid batteries. The Sunnew battery energy storage system uses lithium iron phosphate batteries, which are suitable for household energy storage, commercial and industrial fields.
