Abstract
For a long time, people have been studying solar energy. Our planet receives solar energy, only the sun's surface all the energy issue one billion around the world these energy equivalent to 3-4 times the total energy required is indeed endless, not used exhaust. Secondly, there is no space day and night and seasons, and there is no dark clouds and shadows, radiation energy is stable. , Solar energy and oil, coal and other fossil fuels, would not lead to the greenhouse effect and global climate change will not cause environmental pollution. Because of this, many countries use of solar energy by the attention. This first of a solar energy hot water system has been design, followed by parts of the system control software and hardware design, the final commissioning of the system. Use of microcomputer control section which receives water level sensor, temperature sensor signal feedback to respond to control electromagnetic valve, pumps the implementation of components, thereby to control the hot water system operation.
