Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic energy storage system. Background Art

[0002] Photovoltaic energy storage system is an energy solution that combines solar photovoltaic power generation with electric energy storage technology. It can effectively utilize solar energy and balance the gap between power supply and demand through energy storage equipment. Photovoltaic modules (solar panels) absorb sunlight during the day and convert it into direct current. Direct current can be converted into alternating current through inverters for home or commercial use. If the amount of electricity generated exceeds the immediate demand, the excess energy will be stored in the battery. When there is no sunlight or during peak electricity consumption, the stored energy can be released for use.

[0003] The existing photovoltaic energy storage system collects solar energy and converts it into electrical energy through the solar photovoltaic panels installed on the brackets, and then manages the operation of the entire system through the control module installed in the control box, so that the control module controls the inverter to convert DC power into AC power to meet the needs of household appliances, and the control module regulates the energy storage battery to store excess electricity, so as to achieve photovoltaic energy storage. When installing the photovoltaic energy storage system, the personnel adjust the installation status of the bracket and the solar photovoltaic panel so that the solar photovoltaic panel is in the best position height and tilt state for collecting solar energy, so that the solar photovoltaic panel can better collect solar energy and convert it into electrical energy. As the seasons change throughout the year, the position and height of the sun in the sky do change, and this change It is mainly affected by the inclination of the Earth's orbit around the sun and the inclination angle of the Earth's rotation axis relative to the plane of its orbit (about 23.5 degrees). These changes are particularly important for the design of solar power generation systems because they directly affect the amount of solar radiation received by photovoltaic panels. Therefore, in the use of photovoltaic energy storage systems, personnel are required to regularly go to the location where the photovoltaic energy storage system is installed and adjust the installation status of the solar photovoltaic panels, and readjust and fix the installation height and inclination angle of the solar photovoltaic panels. The adjustment process requires personnel to spend a long time to calibrate the installation height and inclination angle of the solar photovoltaic panels according to the data, so that they are in the best position to collect solar energy, making this process more troublesome, time-consuming and labor-intensive, and bringing a great burden to the work of personnel.
