CONCLUSION
According to the calculation of the solar radiation 4.5kWh/m².day, the power generation of the 351kWp solar power station in the first year is about 440MWh. The electricity price of the factory during the day is about US$0.104/kWh, so it can be seen that the power station can save at least US$45,830 in electricity bills every year. In addition, the annual income of chargers is nearly US$15,000, so the investment payback period of the entire project is about 5 years, which is extremely valuable for investment. At the same time, industrial and commercial photovoltaic charging and storage projects are clean energy projects. According to the annual power generation capacity of the solar power system, it is estimated that at least 30 tons of CO 2 , 0.12 tons of SO 2 and 0.12 tons of NOx can be saved each year. With the increasing development of the international carbon emission trading market, the energy saving and emission reduction will also be one of the main sources of customer benefits in the future.
The development and application of photovoltaic intelligent charging & storage solution will play an active role in the development of power supply and clean energy in the future.
It uses clean energy to supply power and uses battery system to store electrical energy. Photovoltaic, energy storage and charging facilities constitute a microgrid. The microgrid can interact intelligently with the public grid according to demand, and can achieve two different operating modes: grid-connected and off-grid. The application of energy storage system can also reduce the impact of charging piles on the regional power grid during high- current charging.
It can not only provide green electricity for electric vehicles, but also can realize auxiliary service functions such as peak shaving and valley filling, which can effectively improve the operating efficiency of the system.
It will be able to build a system integrating generation, construction, transformation, distribution, and sales in the limited land resources, and achieve a basic balance between local energy production and load consumption through energy storage and optimized configuration. In addition, in many energy storage systems of photovoltaic intelligent charging & storage solution, some batteries that have been eliminated in electric vehicles are also used, thereby realizing echelon utilization of power batteries. If the echelon utilization of batteries can be popularized, this will greatly solve the problem of battery recycling in new energy vehicles. The photovoltaic intelligent charging & storage solution is a bold innovation attempt in the use of renewable energy, energy storage applications and the construction of new energy vehicle charging stations. In recent years, with the support of governments and policies of various countries and regions, the energy storage industry has cooperated with manufacturers, user units, and investment and financing institutions to jointly explore industrial models covering upper, middle and lower reaches. The entire industrial chain of the energy industry accelerates the commercialization of the market process. The photovoltaic intelligent charging & storage solution have gradually become a new focus in the global photovoltaic field.
