With off-grid solar power systems, grid system has the following advantages:

(1) The use of clean, renewable natural energy generating solar power, do not consume non-renewable and limited resources, the carbon content of fossil fuels, the use of no emissions of greenhouse gases and pollutants, and the ecological environment in harmony with the economic and social sustainable development strategy.

(2) The power can be fed into the grid to grid for the energy storage device, dispense with batteries, an independent photovoltaic system can reduce the construction investment of 35% 1 45%, thus greatly reducing the cost of power generation. Dispense with the battery system and improve MTBF and battery secondary pollution.

(3) Components of photovoltaic cells and the perfect combination of buildings, can generate electricity as well as building materials and decorative materials to make full use of material resources to play multiple functions, not only to reduce the cost of construction, and scientific and technological content of the Buildings improve to increase the "selling point. "

(4) Distributed construction, hair scattered nearby power supply, flexible entry and exit grid will help to enhance the power system to resist war and disasters, and help to improve the power system load balancing, and reduce line losses.

(5) Can play a role in peak shaving. Interconnection of photovoltaic solar power system is the world's developed countries in the field of photovoltaic applications competing for the development of hot spots and focus on photovoltaic solar power is one of the world development trend of the mainstream, huge market prospects are broad.
