Tower shield heat insulation waterproof roof system for photovoltaic power generation

Abstract

The invention discloses a tower shield heat insulation waterproof roof system for photovoltaic power generation, and relates to the technical field of energy collection roof coverings. A photovoltaic power generation assembly is installed on the upper portion of a tower shield roof and used for converting solar energy into electric energy; a storage battery pack is installed on the tower shield roof, connected to the photovoltaic power generation assembly and used for storing generated electric energy; and a roof base surface sealing layer is a sealing layer formed by primer sprayed according to different base materials, and plays a protection role in sealing, corrosion resistance and oxidation resistance of an original roof base material. The heat-insulation waterproof coating and the waterproof matched polyester cloth are mixed to form a heat-insulation waterproof layer, and the heat-insulation waterproof layer is laid on the surface of the sealing layer and used for achieving heat-insulation and waterproof effects on the roof; and a finish-coat paint coating is brushed or sprayed on the heat-insulating waterproof layer to form antioxidant finish paint. In the aspect of structure, construction is simple, heat insulation and waterproof effects are achieved, energy conservation and environmental protection are achieved, and meanwhile the generating capacity of a matched roof photovoltaic power generation system is improved.

Description

technical field [0001] The invention belongs to the technical field of energy collection roof coverings, and in particular relates to a tower shield thermal insulation and waterproof roof system for photovoltaic power generation. Background technique [0002] Photovoltaic building roof is a new type of building roof that combines solar energy with building roof, and it is the expansion and development of the concept of building roof. Photovoltaic roofing is the main application of Building Integrated Photovoltaic (BIPV—Building Integrated Photovoltaic), and photovoltaic building roofing will become one of the most important emerging industries. Solar photovoltaic building roofing is a technology that integrates or combines solar power generation (photovoltaic) products on building roofing. It not only has the function of roof envelope, but also can generate electricity for building use. BIPV is a new concept building of "buildings generate energy", which is a building that...

Problems solved by technology

[0006] 1. Increase the roof load: The original design of the old roof usually does not consider the installation of photovoltaic power generation. Although the design load of the roof is large, the load increases after the installation of photovoltaic power generation. Increasing the load of the building will reduce the service life of the building and increase the leakage of water probability

[0007] 2. Difficulty in maintenance: After the photovoltaic power generation of solar panels on the original roof, once the roof leaks, it is difficult to completely repair it. If a thorough repair is required, all solar photovoltaic panels must be dismantled. The probability of breakage increases, increasing input and operating costs

[0008] 3. Increase the hidden danger of water leakage: Photovoltaic power generation panels used on metal roofs, because the roof solar panels have a certain weight, the color steel roof usually does not consider this part of the load in the design, and the effect on the color steel roof affects the stability of its structure itself The joints are more disturbed, which also increases the hidden danger of roof leakage

It can be seen from this that when the solar cell works at a high temperature, the open circuit voltage drops sharply with the increase of temperature, and at the same time causes a serious shift of the charging operating point, which easily causes the system to be damaged due to insufficient charging, and the output power of the solar cell As the temperature rises, it also drops sharply, so that the solar cell module cannot fully exert its maximum performance.

[0015] 2. The influence of temperature on the battery In the photovoltaic power generation system that operates independently, the battery is also a key component, and its main function is to store and adjust electric energy. At present, there is no special battery for solar photovoltaic power generation systems in my country, and conventional lead-acid batteries are mainly used.

[0017] b. The float charge life of the battery changes with the temperature. Basically, every 10°C rise, the float charge life will be reduced by half. High temperature will accelerate the battery dehydration, thermal runaway, positive grid and deformation. Fluctuation will accelerate the internal short circuit of the lead-acid battery and other problems

These can affect battery life
