Photovoltaic grid-connected power generation system for residential buildings

Abstract

The invention discloses a grid-connected photovoltaic power generation system for residential housings. The grid-connected photovoltaic power generation system for residential housings comprises photovoltaic cell panel assemblies and grid-connected inverters, wherein each photovoltaic cell panel assembly is independently connected with the input end of each corresponding grid-connected inverter. In the grid-connected photovoltaic power generation system for residential housings, each grid-connected inverter is independently connected with the corresponding photovoltaic cell panel assembly, electric energy generated by each cell panel can be normally converted and output, the output ends of the grid-connected inverters can be directly inserted into an electric socket to supply electricity to a load and can be connected in parallel to input all generated electric energy to an external power grid to be used, and therefore the grid-connected photovoltaic power generation system for residential housings can greatly improve energy utilization and conversion rate, is strong in practicality and can sufficiently use the photovoltaics to generate electricity.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a photovoltaic grid-connected power generation system for residential buildings. Background technique [0002] With the development of the photovoltaic industry, photovoltaic power generation has gradually extended from the industrial field to the civilian field. Due to the limited space of residential buildings, the number of photovoltaic panels installed is limited. In the traditional grid-connected power generation system, when the number of solar panels installed is low to a certain extent, the output voltage becomes low, which seriously restricts the power generation efficiency of the grid-connected system, and even the inverter in the traditional grid-connected power generation system cannot be started to work. When the inverter fails to work, the electricity generated by the photovoltaic panel components cannot be converted and output normally, resulting in the shutdown of the en...

Problems solved by technology

In the traditional grid-connected power generation system, when the number of solar panels installed is low to a certain extent, the output voltage becomes low, which seriously restricts the power generation efficiency of the grid-connected system, and even makes it impossible to start the inverter in the traditional grid-connected power generation system

When the inverter fails to work, the electricity generated by the photovoltaic panel components cannot be converted and output normally, resulting in the shutdown of the entire grid-connected power generation system

[0003] Based on the above reasons, some residential buildings cannot install a sufficient number of photovoltaic panels, resulting in the failure of the entire photovoltaic grid-connected power generation system to be installed, which affects the application of photovoltaic grid-connected discovery in the civilian field
