In recent years, green energy related issues have been discussed for a long time. And, how to obtain hot water economically is one of the issues. Except traditional firewood method, there are electric-heater, gas, and solar water heater to obtain hot water. However, the firewood method is inconvenient; and incomplete gas heating releases carbon monoxide. Comparing with other methods, solar water heater with energy-saving and carbon reduction characteristics is therefore the mainstream of future development.
The present solar water heater system can not effectively collect enough solar energy to heat water during continuous cloudy and rainy days. To solve this problem, an electric-heater stick is installed in solar water heater system to facilitate the heating. However, this increases the energy consumption from grid-source. Especially, in the rainy season, the power consumption of the heater should not be underestimated.
The main purpose of this research is to apply wind power generator module to the present solar water heater. This wind power generator module supply energy to another auxiliary electric-heater to heat water in the storage-tank. While the heat is not enough, instant energy can be supplied by the electricity. This module decreases the dependence of the grid-source and reduces the demand of electricity.
