Description

technical field [0001] The invention relates to a solar energy device, in particular to an integrated solar energy device combined with a building. Background technique [0002] At present, the energy consumption of buildings in China accounts for a relatively large proportion of the energy consumption of the whole society. The energy consumption of hot water, air conditioning and heating accounts for about 65% of the energy consumption of buildings. The comprehensive utilization of solar energy fully realizes the integration of solar energy and buildings and solar thermal photoelectricity. Application integration, solar hot water can supplement 15% of building energy consumption, heating and cooling systems can solve 50% of building energy consumption, photovoltaic power generation can save 30% of building energy consumption, and the most ideal zero-energy house can be built . [0003] Different heating systems have different heating energy consumption. For example, to pro...

Problems solved by technology

[0004]The common building-integrated solar installations are mostly solar water heaters and flat-panel photovoltaic modules. Due to the lack of supervision and design awareness of the former, solar water heaters are installed everywhere, which is not compatible with buildings. The lack of uniformity affects the appearance of the building; at present, the collectors mainly include all-glass vacuum tube solar collector tubes and flat panel collectors, of which the former is an explosive tube, which has poor compression and shock resistance, and the latter has 4mm tempered glass and an aluminum alloy frame. , can operate under pressure, easy to combine with buildings, but the cost of a single module is high

When designing in combination with the inclined sun-facing roof structure, generally take the local latitude plus 10° in winter and minus 10° in summer; for flat-panel photovoltaic modules, they are generally arranged obliquely on the roof structure of the building or on the wall surface to receive solar light for power generation. However, photovoltaic cells can only receive energy of one solar intensity, and a larger photovoltaic cell area is required to obtain a specific power generation. Although the price of photovoltaic cells has been reduced, the overall module cost and installation cost are also high; in addition, there is a A model of photovoltaic / solar-thermal building integration (cogeneration), which uses water to cool photovoltaic cell modules, and obtains hot water at a certain temperature during the process of photovoltaic cell power generation; for example, the International Energy Energy Association (IEA) formulated in 2005 launched a 3-year "PV / T solar energy system" research plan; through the thermal imager, it can be seen that the temperature of water-cooled PV / T cells is about 20°C lower than that of uncooled cells; the efficiency of general solar silicon cells is higher than 25°C When the temperature is increased by 1°C, the efficiency will drop by about 0.4%. However, if you want to obtain more energy, you still need a larger receiving area of ​​photovoltaic cells if you want to use one solar light, and the cost is still high. Large-scale use in rural construction; how to obtain a low-cost comprehensive utilization technology that uses less photovoltaic cells while taking into account solar photovoltaic power generation and solar thermal utilization has become an important bottleneck for the large-scale implementation of solar building integration
