Question

Class activity 3 1- List at least 3 advantages of thermal energy storage 2- List at least 3 disadvantages of thermal energy storage 2. Explain clearly the principle of operation of the solar hot water system shown below

Answer 1

Advantages - No fuel price -Solay thermal Energy doesn't need any gasoline like most other Sources of green energy 1. predictable, 24/7 power - solar thermal energy can generate energy 24 hours a day. 3. No pollution e international warming issues. principle of operation: - water is hosted by the solar thermal energy absorbed by the Collectors The hot water with lower density moves uluards & Cold water uith higher density moves down from the tank due to gravity > Ece A bank of Collectors can be arranged in a series - parallel combination to get higher quantity of water. Disadvantages 1. Tall prices. costs about Euro 3.5 watt 2. Water issue - utilizes a lot of water that will be significant problem in Desest areas. 3. Limited places and size limitation only built in places which have the large level of solar power radiation. 4. Long gestation time causing cost overruns. EX 100 litre tank Collector area sama then water temperature is heated to 601-584
