Abstract

The invention provides an energy storage type solar power generation device which comprises a photovoltaic power generation module, an electric power storage module and an electric control system, wherein the electric power storage module comprises a solar thermal collector, a heat accumulation device and an electric power storage device; the solar thermal collector leads part of the collected solar heat energy to be stored inside the heat accumulation device which provides heat for the electric power storage device; and the photovoltaic power generation module is connected with an electric control system and the electric power storage device which is connected with the electric control system. The device can store the electric energy of the photovoltaic power generation part when in trough of energy consumption and release the electric energy when in peak of the energy consumption, thus leading the system to have the function of 'peak load shifting' and enhancing the stability of the system.

Description

technical field [0001] The invention relates to an energy efficient utilization system, in particular to an energy storage type solar energy system. Background technique [0002] In the past century, the development and utilization of fossil energy such as coal, oil, and natural gas has opened the prelude to the era of large industries, and the total annual energy supply of mankind has increased by nearly 10 times. However, unrestrained resource development and inefficient energy utilization have resulted in a large amount of waste of resources, increasingly serious ecological environment pollution and shortage of energy resources, and the living space of human beings has been greatly threatened. In the new century, energy science We have to face the triple pressure of resource waste, resource shortage and environmental pollution at the same time. Therefore, people gradually turn their attention to the efficient use of renewable resources and energy storage. [0003] The wo...
