Solar power generation into off-grid power systems and grid systems: Off-grid power systems. Mainly consists of solar modules, controller, battery composition, to an AC load, also need to configure AC inverter. DC power generation system is generated through solar modules and grid-connected inverter converts AC power into the electricity grid in line with the requirements of direct access to the public grid after this. And power generation systems have centralized large-scale power plants are generally national grid station, the main feature is the power can be directly delivered to the grid by grid power to the unified deployment of the user. But this power plant investment, long construction period, large area, the development of a relatively large degree of difficulty. The small and decentralized power generation systems, especially BIPV power system, due to the small investment, quick construction, small footprint, large policy support, etc., is the grid of the mainstream.

The lithium-ion battery electrolyte material different from the lithium-ion battery is divided into liquid lithium-ion battery (Liquified Lithium-Ion Battery, referred to as LIB) and lithium-ion polymer battery (Polymer Lithium-Ion Battery, referred to as the PLB) with lithium or plastic ion battery (Plastic Lithium ion batteries, referred to as the PLB). Anode and cathode materials used in lithium-ion polymer battery with liquid lithium-ion is the same, divided into cathode material of lithium cobalt oxide, lithium manganese oxide, LifePo4 ternary materials and materials, graphite is extremely negative, the battery works basically consistent. The main difference lies in the different electrolytes, liquid lithium-ion battery using a liquid electrolyte, lithium-ion polymer battery Zeyi solid polymer electrolyte to replace, such polymers can be "dry state", it can be "colloidal" currently most using a polymer gel electrolyte.
