Embedded modular photovoltaic system

technical field

The invention relates to solar power generation equipment, in particular to an embedded module photovoltaic system.

Background technique

Today, when traditional energy sources are increasingly scarce, solar energy has attracted more and more attention due to its advantages of cleanness, pollution-free, and huge reserves. Various types of solar power generation equipment are emerging in the market. Solar photovoltaic modules are popular solar power generation equipment in recent years. The main types are standard photovoltaic modules, double-glass photovoltaic modules and thin-film battery modules. Standard photovoltaic modules use ordinary frames to encapsulate solar panels, and are mainly used in centralized photovoltaic power plants and building roofs. The application on the roof adopts an additional integration method, which requires a separate installation framework, which cannot realize the integration of photovoltaic buildings, has the problem of repeated construction, and will destroy the existing waterproof system of the roof. Double-glass photovoltaic modules are two pieces of tempered glass with solar panels sandwiched between them. They are mainly used in building curtain walls and lighting roofs. They can realize building-integrated photovoltaic installations. However, the heat dissipation performance of photovoltaic module cells is poor, and the temperature causes power generation Reduced efficiency. Thin-film photovoltaic modules use adhesives to stick the modules on the surface of buildings. The power generation efficiency is only about 6%, which is lower than that of crystalline silicon photovoltaic modules. At the same time, the bonding effect is significantly affected by the external climate, and the power generation efficiency decays quickly. Solar photovoltaic building integration refers to the interconnection of solar photovoltaic modules to form a photovoltaic array, which replaces building envelope components, combines photovoltaic modules with buildings, and meets the requirements of preventing rainwater leakage. However, the application of the above three mainstream photovoltaic modules in buildings has different limitations and deficiencies, and it is necessary to improve them.
