Alternative solar hot water system with multistorage tank

Abstract

The use of renewable energy has been spread all over the globe very rapidly. Renewable energy is the energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). Along with the major developments in the alternative sources of energy, a major breakthrough is the solar energy. More energy from sunlight strikes Earth in one hour than all of the energy consumed by humans in an entire year. So it is very convenient to utilize this energy in our daily life. In many other countries solar energy is being used within vast area. Researches are going on to make the solar system more efficient and affordable.

So it has been necessary to bring the idea of using solar energy in our country in wide range including domestic purpose. It will be in fact a great achievement if we can minimize electricity consumption by substituting it with solar energy. This thought leads us to work on our project which is on the topic “Alternative Solar Water Heater with Automated Control System”.

Using solar energy to supply hot water for both industrial and domestic purpose can be a very good application of utilizing solar power and that is the target that we will be trying to achieve. Our task is to implement a solar water heater along with a backup water heater controlled by a controller to ensure the constant hot water supply in the cheapest possible way. Our thesis work also provides a solution to increase the efficiency of solar water heater by implementing high capacitive multiple hot water storage tanks.
