Description

technical field [0001] The invention belongs to the field of solar photovoltaic power generation, and in particular relates to a solar photovoltaic high heat insulation window in a photovoltaic building integrated power generation system. Background technique [0002] Solar energy is an inexhaustible clean energy. In today's increasingly serious global environmental pollution and energy crisis, the study of solar energy utilization is of great significance to alleviate the energy crisis, protect the ecological environment and ensure the sustainable development of the economy. [0003] The solar energy industry is divided into solar thermal utilization and solar photovoltaic power generation. Solar thermal utilization mainly includes solar water heaters, and solar photovoltaic power generation mainly includes solar photovoltaic power plants and solar photovoltaic building integrated power generation systems. [0004] At present, the classification of solar photovoltaic power...

Problems solved by technology

[0009] 1. Non-hollow glass photovoltaic windows, the glass of which is a layer of laminated glass containing battery packs. Although it can generate photovoltaic power, the heat preservation and energy saving indicators in most areas of the country cannot meet the national mandatory standards for energy saving of doors and windows. Product promotion is limited

[0010] 2. Ordinary insulating glass photovoltaic windows, photovoltaic insulating glass composed of single-cavity grooved aluminum, although the energy-saving performance meets the requirements, but during the power generation process of photovoltaic windows, the battery pack will generate a certain amount of self-heating, and the air temperature in the hollow layer will rise. High, resulting in a reduction in the power generation efficiency of the battery pack, and the insulating glass is also prone to self-explosion

[0011] To sum up, based on the technical status of solar photovoltaic windows, the country is currently unable to classify "solar photovoltaic windows" into the category of photovoltaic components of photovoltaic building integration in terms of photovoltaic power generation classification.
