Off grid solar system is suitable for areas where there is no grid-connected or grid-connected power instability. Photovoltaic off-grid systems are usually composed of solar modules, controllers, inverters, battery packs and bracket systems. T
Composition and function of 3KW off grid power generation system
Solar panel: the core part of the 3KW off grid solar system, and the most valuable part of the solar power system. Its function is to convert the radiation capacity of the sun into electr
Features of 4KW grid-connected solar photovoltaic power generation home system:
System composition: photovoltaic panels, solar inverters, fixed brackets, two-way electricity meters (provided by the grid for free), cables (users configure according to their actual installation conditions)
The general energy storage lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte, which is different from lithium ion secondary batteries and lithium ion polymer batteries.
The lithium-ion battery type industry chain mainly includes four links: raw materials, equipment, batteries and terminal applications. Lithium battery equipment is mainly used in the production process of lithium batteries and is in the middle of the entire lithium battery industry chain.
The off-grid solar power generation system can be applied to the user's solar power supply: (1) Small-scale power supplies ranging from 10-100W, used in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts and other military and civilian life power, such as lighting, TV, radio and television etc.; (2) 3-5KW household rooftop grid-connected power generation system;
(3) Photovoltaic water pump: solve the drinking and irrigation of deep wells in areas without electricity.
The buildings are basically single-family houses, and the surrounding areas are relatively empty and there is no shelter. Therefore, the roof area of the building is used to the greatest extent. After considering both environmental protection and energy saving, people began to gradually reform the roof design. Large-area sloping roofs Or flat roofs begin to fully replace the former European-style roofs with multiple roof windows, which provides the most basic space for the installation of solar power systems.
The role of the solar controller is to control the working state of the entire system, and to protect the battery from overcharge and overdischarge. In places with large temperature difference, a qualified controller should also have the function of temperature compensation. Other accessory functions such as light-controlled switches and time-controlled switches are optional for the controller.
A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work with the photoelectric effect are the mainstream, and the diverse prices of solar system cells have troubled some people how to choose solar cells. Today, I will briefly introduce the knowledge about the purchase of solar cells
