On grid solar system refers to a photovoltaic power generation system that converts solar energy into electrical energy and directly sends electrical energy to the public grid through a grid-connected inverter without going through battery storage. Grid-connected solar power generation represents the development direction of solar power and is the most attractive energy utilization technology in the 21st century.

On grid solar system application scenarios

1. User solar power supply:

(1) Small power supplies ranging from 10-100W, used for military and civilian life in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts, etc., such as lighting, TV, etc.; (2) 3-5KW household rooftop grid-connected power generation system ;(3) Photovoltaic water pump: solve the problem of drinking water and irrigation from deep wells in areas without electricity.

2. Communication/communication field:

Solar unattended microwave relay stations, optical cable maintenance stations, broadcasting/communication/paging power systems; rural carrier telephone photovoltaic systems, small communication machines, soldier GPS power supply, etc.

3. Petroleum, ocean, and meteorological fields:

Petroleum pipelines and reservoir gate cathodic protection solar power systems, oil drilling platform life and emergency power supplies, ocean detection equipment, meteorological/hydrological observation equipment, etc.

4. Photovoltaic power station:

10KW-50MW independent photovoltaic power stations, wind and solar (diesel) complementary power stations, various large parking plant charging stations, etc.

Advantages of grid connection

(1) Economy: Grid connection can combine the photovoltaic power generation systems of multiple users into a large power network, improve power generation efficiency, and then reduce the unit price, thus achieving the purpose of saving energy.

(2) Stability: Grid-connection combines the photovoltaic power generation system with the power network, which can alleviate stability problems caused by weather, environmental and other factors limiting the photovoltaic power generation system.

(3) Environmental protection: Solar photovoltaic power generation is a clean energy. Compared with traditional coal-fired and oil-fired power generation, it is green, environmentally friendly, noise-free and pollution-free, and can give full play to its advantages of being environmentally friendly.
