on grid rooftop solar systems

The solar grid-connected power generation system converts solar energy into electrical energy, without battery storage, and directly sends the electrical energy to the grid through the grid-connected inverter. Solar grid-connected power generation represents the development direction of solar power sources and is the most attractive energy utilization technology in the 21st century.
(1) It uses clean, renewable natural energy solar energy to generate electricity, does not consume non-renewable, limited carbon-containing fossil energy, and does not emit greenhouse gases and pollutants during use. It is in harmony with the ecological environment and in line with the sustainable development strategy of the economy and society.

(2) The generated energy is fed into the grid, which is used as an energy storage device, eliminating batteries. The construction investment can be reduced by 35% to 45% compared with an independent solar photovoltaic system, thereby greatly reducing the cost of power generation. Eliminating batteries avoids secondary pollution of batteries and increases the average failure-free time of the system.

(3) The photovoltaic cell components are perfectly combined with buildings. They can generate electricity and be used as building materials and decorative materials, making full use of material resources to play multiple functions. This not only helps to reduce construction costs, but also improves the technological content of buildings and increases "selling points".

(4) Distributed construction, decentralized power generation and supply nearby, flexible entry and exit from the power grid, which is conducive to enhancing the power system's ability to resist war and disasters, and is conducive to improving the load balance of the power system and reducing line losses.

(5) It can play a peak-shaving role. Networked solar photovoltaic systems are the hotspot and focus of the world's developed countries in the field of photovoltaic applications. It is the mainstream development trend of solar photovoltaic power generation in the world, with a huge market and broad prospects.
