Abstract

The invention provides a photovoltaic power generation system. The photovoltaic power generation system comprises a photovoltaic module, a reflecting plate, an inverter and a power distribution box, wherein the photovoltaic module and the reflecting plate are arranged on a first surface, the inverter is electrically connected with the photovoltaic module, the power distribution box is electrically connected with the inverter, the photovoltaic module is provided with an incident surface, the reflecting plate is provided with a reflecting surface, the incident surface and the reflecting surface are opposite to each other, and the minimum distance between the incident surface and the reflecting surface along a direction parallel to the first surface is sequentially increased along a direction far away from the first surface. By the reflecting surface of the reflecting plate, more sunlight can be reflected to the incident surface of the photovoltaic module, the power generation efficiency of the photovoltaic module is improved, a direct current output from the photovoltaic module is converted to an alternating current by the inverter and then is transmitted to the outside via the power distribution box, so that the photovoltaic power generation system can have high power generation quantity; and moreover, the photovoltaic power generation system is low in cost, extra occupancy area is not needed to be added, the photovoltaic power generation is simple and easy to maintain and is suitable for a medium-size distributed photovoltaic power station.

Description

technical field [0001] The present invention relates to the field of photovoltaic technology, in particular to a photovoltaic power generation system. Background technique [0002] Energy is the cornerstone of the existence and development of modern society. With the continuous development of the global economy and society, energy consumption also continues to grow accordingly. Solar energy is an inexhaustible renewable energy source for human beings. It is fully clean, absolutely safe, and relatively extensive. Solar energy is an "inexhaustible and inexhaustible" safe, Environmentally friendly new energy is getting more and more attention and plays an important role in the long-term energy strategy. [0003] Photovoltaic power generation is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-conne...
