Building integrated solar power generation system

Abstract

The invention discloses a building integrated solar power generation system. A wind driven generator or a solar photovoltaic cell assembly is connected to a socket or a direct current or alternating current dual-purpose load of each of user sides through a direct current transmission line and a direct current electric energy meter; the load can be a direct current or an alternating current/direct current multifunctional air conditioning system and can also be a direct current or an alternating current/direct current dual-purpose electric water heater, or a direct current or an alternating current/direct current dual-purpose electric boiling-water heater, or a direct current or an alternating current/direct current dual-purpose semiconductor air-conditioner, or a direct current or an alternating current/direct current dual-purpose electric fan, or a direct current or an alternating current/direct current dual-purpose light-emitting diode (LED) lamp, or a direct current or an alternating current/direct current dual-purpose electric heating device; and when solar photovoltaic cell assemblies among units or rooms and even residential plots are in parallel connection and surplus electricity is generated and used independently, and the electricity is connected to an inverting device and an electricity sold electric quantity metering device though a total direct current transmission line and then is sold to large power grids.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a building-integrated solar power generation system. Background technique [0002] Solar energy is becoming the first renewable energy source due to its many advantages such as clean and pollution-free, large reserves and low cost of use. Many regions have issued documents that require multi-storey and small high-rises below 12 floors, as well as the top floors of high-rise buildings to install solar water heating systems. The renovation of old houses or the integration of solar energy and buildings in new houses has begun pilot promotion. . [0003] According to the existing technical conditions, the building-integrated solar energy system that can be constructed simultaneously with the building mainly includes centralized heat collection, household heat storage, household auxiliary heating system, centralized heat collection, central heating, and household metering system. ...

AI Technical Summary

Problems solved by technology

However, the cost of centralized heat collection, household heat storage system, and household auxiliary heating system is high, and the energy saving of each user is inconsistent; when centralized heat collection, central heating, and household metering system have high requirements for property management and the occupancy rate is not high High cost per user

[0004] The latest patents 201010111686.3 Unitary Residential Solar Centralized Hot Water Supply System and 201110366676.9 Residential Solar Integrated Heating System have better solved the above defects, but both of these solutions use a circulation system, the operating cost is still high, and there is a large amount of surplus heat in summer There is also the problem of water outlets, which do not take full advantage of the solar energy gained
