With the increase of conventional energy resource

the shortage of energy and environmental pollution are getting worse. Therefore

the development of clean energy is urgent. Rural areas mainly utilize small stoves for heating in northwest China. Not only are there safety risks

but large areas of coal heating will cause air pollution seriously. This project plans to adopt grid-connected photovoltaic power generation system for heating

which can not only reduce energy shortage but also improve air pollution. At present

rural areas mainly utilize small stoves for heating in northwest China. Clean energy heating system can completely or partially replace a boiler powered by conventional energy

such as coal

petroleum

natural gas and can achieve energy of sustainable development.
