Novel photovoltaic power generation system with high power generation efficiency

Abstract

The invention relates to the field of new energy sources, in particular to a novel photovoltaic power generation system with high power generation efficiency. The existing photovoltaic power generation solar panel has the two modes including a fixed mode and a tracking mode; for the fixed installation, the inclination angle of the solar panel is unchanged, and the power generation efficiency is low; when a tracking device is installed, the sun position can be tracked; more sun radiation can be received, but the structure of the tracking device is complicated, the initial investment and maintenance cost are too high, and the cost performance is not high, so that most photovoltaic power generation uses the fixed installation. Under the condition that the photoelectric conversion rate is difficult to improve in a short period, how to improve the solar power generation efficiency belongs to a technical problem urgently needing to be solved in photovoltaic power generation at present. The invention provides a technology for regulating the inclination angle of a photovoltaic assembly. The technology has low initial investment and low maintenance cost, and can replace a solar tracking device. Compared with photovoltaic power generation with the same installed capacity and unchanged inclination angle, the novel photovoltaic power generation system has the advantage that the photovoltaic power generation quantity is increased by about 40 percent.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a novel photovoltaic power generation system with high power generation efficiency. Background technique [0002] At the Paris climate summit at the end of 2015, China stated that it would reduce carbon dioxide emissions per unit of GDP by 40% to 45% from 2005 levels by 2020. In order to achieve the goal of reducing carbon emissions, my country is rapidly reducing its dependence on coal-fired power generation, gradually reducing coal-fired power generation, and increasing the use of renewable energy will be the development direction of the country's future energy policy. The National Energy Administration announced in November 2013 On the 26th, the "Interim Measures for the Supervision of Photovoltaic Power Generation Operations" was issued, stipulating that power grid enterprises should fully purchase the on-grid electricity of grid-connected photovoltaic power station projects and dist...
