Building material-type roof photovoltaic tracking tile generating system

Abstract

The invention relates to a building material-type roof photovoltaic tracking tile generating system which has the concrete scheme that a solar-cell panel, a condenser, a flexible leakage-prevention plate and the like are supported by a plurality of linkage tracking supports, and a linear actuator is controlled by a solar controller to pull the supports back and forth to rotate along a base support shaft to track the sun each day to make the cell plate and a roof tracking system vertically irradiated by the sun to realize the integration of main construction roofs with multiple purposes of solar tracking, condensation and light filling, rain protection, sound insulation, heat insulation, sun shading, attractive appearance, power generation and the like and photovoltaic solar energy. The invention can be applied to constructions such as dwelling villas, industrial factory buildings, large-sized public venues and the like and meanwhile realizes the complete integration of the solar energy and the constructions.

Description

technical field [0001] The invention relates to a building material-type roof photovoltaic tracking tile power generation system, which belongs to the integrated technology of solar thermal and photovoltaic utilization and building Background technique [0002] As an energy form of renewable energy, solar energy has many disadvantages compared with clean energy such as water and wind power, and also has incomparable advantages compared with clean energy such as water and wind power. One of the biggest advantages is that the form of solar power generation can be closely integrated with buildings, which can reduce construction investment without occupying other resources such as land. Because solar cells and modules were originally designed to be used for power supply on satellites, and were not designed according to the characteristics of buildings, so in general, solar panels and support systems can only be laid on the basis of building roofs.

Problems solved by technology

Because solar cells and modules were originally designed to be used for power supply on satellites, and were not designed according to the characteristics of buildings, so in general, solar panels and support systems can only be laid on the basis of building roofs. It is equivalent to laying the roof twice, which increases the cost of the overall building and power generation system. At the same time, the ground solar photovoltaic power generation system can use solar trackers to make the solar power generation system always track the sun, so that the power generation per unit area of ​​the battery is greatly improved. The improvement of the ground solar power generation system has greatly reduced the electricity cost, and the electricity cost of the building roof solar power generation system is higher than that of the ground solar power generation system.

For example: patents 200810234316.1, 200820161229.3, and other inventions adopted the traditional trough geometric ratio of more than 3 times to concentrate light 20-30 years ago, and used a medium for cooling behind. The optical part of the system has poor tolerance to the increase in optical tracking requirements, the operating temperature of the battery is greatly increased, and the electrical performance is greatly depleted. At the same time, due to the increase in auxiliary cooling, the number of working parts in the entire system will increase a lot and the stability will be poor. The cost of equipment is compared with the cost of power generation. Increase

Especially when the earth is constantly revolving around the sun, and the north-south radiation angle is constantly changing with the seasons, and the east-west radiation angle is constantly changing with the change of the morning, middle and evening time, because the sun is constantly changing, without installing solar tracking In the case of the device, the utilization efficiency of solar energy cannot reach the maximum, and it will also cause the system to not generate electricity at all in the dead angle of the sun, and the economy will be reduced instead.

Therefore, the utilization of solar energy cannot be popularized in a large area.

In order to make solar energy more popular, many people have begun to study solar tracking systems, especially in solar concentrating systems used to increase the sun's density, it is difficult to avoid supporting solar tracking systems
