Solar photovoltaic and photo-thermal roof system

Abstract

The invention discloses a solar photovoltaic and photo-thermal roof system. The solar photovoltaic and photo-thermal roof system comprises a plurality of solar photovoltaic and photo-thermal plates, a water delivery pipe and a supporting structure, wherein solar photovoltaic and photo-thermal plates are fixed on the supporting structure through connecting parts and are in lap joint with one another in the longitudinal direction, heat exchange pipes are arranged inside solar photovoltaic and photo-thermal plates, and the water delivery pipe is connected with water inlets and water outlets of heat exchange pipes through pipelines. According to the system, solar photovoltaic and photo-thermal plates are fixed on the supporting structure at the top of a building through connecting parts, are in lap joint with one another in the longitudinal direction and can be laid on a roof in a large area, so that the photovoltaic and photo-thermal utilization efficiency is improved, modern traditional roofs can be replaced completely or partially, the overall installation and usage costs can be reduced, and the waterproof performance of the solar roof can be improved.

Description

technical field [0001] The invention relates to energy-saving buildings, in particular to a solar photovoltaic photothermal roof system. Background technique [0002] With the rapid development of science and technology, human beings' ability to exploit traditional energy sources such as oil and coal has increased rapidly. Looking for clean, green, and renewable new energy sources to replace traditional energy sources, solar energy is one of such energy sources, and it is the new energy source with the most development potential among all new energy sources. [0003] In recent years, with the acceleration of urbanization in countries all over the world, especially developing countries, and the continuous improvement of people's requirements for living comfort, building energy consumption is becoming a black hole that accounts for the largest share of energy consumption in the whole society. On the one hand, conventional energy is increasingly scarce; on the other hand, bui...

Problems solved by technology

There are also some problems in this invention. For example, the solar photovoltaic photothermal roof cannot be laid vertically and horizontally at the same time, and cannot be used in a large area, and the roof is poor in waterproofness, which makes it easy for the solar photovoltaic photothermal panel to enter water.
