Wind energy complementary systems are designed for areas rich in wind resources and are a new type of heating equipment suitable for both household and commercial users. They provide uninterrupted heating throughout the heating season and can be widely used in pastures, remote outposts, and resort areas where electricity and heating are unavailable. The principle is: the electrical energy generated by wind turbines is converted into heat energy, which is then directly stored in the solid-state heat storage heating units of the wind power generators, providing a heat source for heating and hot water supply.
Photovoltaic thermal systems convert sunlight absorbed by solar photovoltaic devices into electricity, which is then transformed into heat and stored in solid heat storage heating units. This creates a system from photovoltaic power generation to solid heat storage for heating and hot water supply, addressing the issue of photovoltaic power generation not being able to connect to the grid. It achieves the conversion of electrical energy into heat energy to meet customers' heating and hot water needs.
