Two DC Photovoltaic Power Generation Systems

The last textile we talked about the No-battery DC photovoltaic power generation system. We could see that there are many unconvenience when use no battery solar power systems. One of the biggest problem is that we can't use the energy in the night and in the daytime that without sunshine. It is not convenient. How about a solar power system with battery? Let's see it.

2. DC photovoltaic power generation system with battery

A DC photovoltaic power generation system with a battery consists of solar cells, solar controller, storage battery and DC load. When there is sunlight, the solar cell converts solar energy into electrical energy for the load to use, and stores electrical energy to the battery at the same time. At night or in cloudy and rainy days, the battery supplies power to the load. This kind of system is widely used, ranging from solar lawn lights and garden lights, to mobile communication base stations, microwave transfer stations far away from the power grid, and rural power supply in remote areas. When the system capacity and load power are large, solar cell arrays and battery packs are required.
