Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic structure installation, and in particular to a roof photovoltaic structure and an installation method thereof. Background Art

[0002] Rooftop photovoltaic is a technology that uses solar energy to generate electricity. It converts solar energy into electrical energy by installing solar photovoltaic modules, photovoltaic inverters, photovoltaic brackets and other components on the roofs of houses or other buildings. It is composed of several photovoltaic cells and is the core component for converting light energy into electrical energy. When photons hit the surface of photovoltaic cells, the semiconductor material in the photovoltaic cells absorbs the photon energy and generates electron-hole pairs. Under the action of the built-in electric field, electrons and holes are separated and form current, thereby realizing photoelectric conversion. Photovoltaic panels are installed through photovoltaic brackets to support and fix photovoltaic modules so that they can stably receive sunlight. The direct current generated by photovoltaic modules is converted into alternating current through photovoltaic inverters for use in homes or businesses. Rooftop photovoltaic can be widely used in various types of buildings, such as residential, commercial buildings, industrial plants, public facilities (such as schools, hospitals, government office buildings) and agricultural facilities (such as greenhouses, farmhouses). Through the mode of self-generation and self-use and the access to the grid of surplus electricity, rooftop photovoltaic power generation projects can effectively reduce electricity bills and improve economic benefits.
