Embodiment
[0022] refer to figure 1 , the present embodiment discloses a solar battery set based on the Internet, and the solar battery set includes all solar panels. The 10MW solar cell set is composed of 10,000 solar cell panels, the solar cell set includes solar cells, and every three solar cells 1 of the solar cells are connected in series to form a solar cell group, and each solar cell The cell group is connected to the first DC / DC boost converter. Each solar cell group uses three cells in series. The output voltage of a single cell is 0.5v, and the voltage after series connection is 1.5v. Through the DC / DC step-up converter 2. Boost 1.5v to 3.0v and stabilize it to 3.0v. Since the minimum input voltage of the current DC / DC boost converter 2 is 0.8v, as long as the input voltage is greater than 0.8v, the output voltage changes and the output current mode keeps the voltage output at 3.0v, and the input terminal is isolated from the output terminal. Two adjacent DC / DC boost converte...

The invention discloses an internet-based solar battery set and a monitoring system and monitoring method thereof. Solar battery slices and a monitoring system are arranged. The solar battery slices are isolated from each other by optocoupler relays and units are isolated from each other by optocoupler relays. A plurality of solar battery panels are connected in series to improve the voltage of the large system to be in a high-voltage direct-current range. An inverter is used for carrying out conversion to obtain three-phase high-voltage alternating currents for direct grid connection. Besides, the monitoring system consists of a monitoring terminal, a monitoring platform and an operation management system. The monitoring terminal monitors that the solar battery slice groups of each solar battery panel at the two sides of the longitudinal edge or the two sides of the latitudinal side have different output powers and carries out communication with the monitoring platform and the operation management system by a fiber communication network; and the operation management system receives the information and then adjusts the latitude and longitude of a solar battery rack, thereby realizing vertical sun tracking. Therefore, problems of short vertical sun irradiating time and low sunlight utilization efficiency of the existing solar battery are solved; and the cost of the auxiliary equipment is lowered.
Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to an Internet-based solar cell set and its monitoring system and monitoring method. Background technique [0002] With the continuous consumption of traditional energy, new renewable clean energy has become a topic of concern in the world. As a new type of renewable and clean energy, solar energy has a wide range of utilization, no damage to the ecological environment during the development process, and a large storage capacity. Solar cells use these advantages to convert solar energy into electrical energy. Traditional solar cells are composed of several solar cells connected in series, because there is no isolation measure between the solar cells, as long as one cell is not working or not working properly, the solar cell will have no power output. Solar cells are affected by the time period, season, climate, and region when receiving solar radiation, and its energy output ch...
