Application Scenarios

The Commercial & Industrial photovoltaic intelligent storage & charging solution integrate distributed solar systems, energy storage systems, charging systems, and monitoring platform. This solution makes full use of the roof and carport of the building to construct a solar system. The generated electric energy firstly supplies electric vehicles and other loads in the factory, and the excess electric energy will be stored in the energy storage system to supplement when the solar energy system is insufficient. Through the coordination between solar energy and energy storage systems, it can minimize the amount of electricity obtained from the grid and increase customer profits.

Application scenarios:

  • During the day, when the solar radiation is sufficient, the solar system directly supplies power to the charger and the factory load, and the excess power will be stored in the energy storage system.
  • During the peak electricity consumption period, the energy storage system meets the load's electricity demand through discharge and achieves peak-to-valley income.
  • When the power generated by the solar system cannot meet the power demand of the load, the energy storage system will provide supplement.
  • When the energy storage system is not fully charged, it can be charged at night when the electricity price is low, and discharged during the peak hours of the next day to obtain electricity income between peaks and valleys.
  • The system is dispatched and adjusted according to power demand, so that the solar system, energy storage system and charging system are perfectly coordinated, thereby increasing customer revenue.

System Design

 

The power station uses the factory roof and carport roof to install solar power system, with a total installed capacity of about 351kWp. The usable area of the factory roof is about 2400㎡, and 234kWp solar modules can be installed. The factory has 40 parking spaces and a carport area is about 500㎡, and a total installed capacity of solar modules is 117kWp.

The energy storage system adopts a modular design with an installed capacity of 100kW / 256kWh. The charging system uses one 60kW dual-gun DC charger and six sets of 7kW AC chargers, with a total of 8 charging parking spaces, the total installed power is 102kW.
