Solar+thermal

 - The solar thermal technology is same idea with that the temperature of room increases during summer. From this concept, this technology transfer heat energy from room to water so that people can use hot water for bath, shower or cleaning without spending electricity. Also, this hot water runs through floors of house to keep warm temperature during cold season even though Australian houses are not required. The other cold area countries spend great number of energy to heat their room. ** Solar thermal system  **  - Solar thermal technology is basically heating the water as the collector captures solar energy to transfer into heating energy. Also, It is one of the simplest way to generate electricity. Converted heating energy boils water or oil so that the steam will operate steam turbine which can generate electricity. However, there is many conditions to use this system such as weather, degree of collecting panels or boiler storage. Residential **Solar thermal system**  **Typical plant size** :  - The plant size is various option for every requirement. Because generated energy will be wasted if it is over-charged or not used. Therefore, it is not good idea to have bigger panels than actual required usage.  - There are two ways to use solar thermal system.  a. One is small plant for residential uses purpose. Residential plant is very small size and depending on the size of roof and direction. At this time, solar energy is only converted to heating energy to provide hot water and HAVC purpose.  b. The other way is commercial purposes plants that large collectors, such as reflectors and lenses, concentrate the sun energy to systems(Trough system, Tower System and Parabolic dish system)  i. ** Trough system ** – array of linear parabolic concentrator to focus the sunlight into a collector pipe that then pipes the fluid to a central point.  ii. ** Tower System ** – a field of tracking mirrors reflects th sunlight onto a centrally located tower containing the fluid  iii. ** Parabolic dish system ** – an array parabolic dish concentrators that focus the sunlight to a point at the focus of each dish to heat a fluid. (Source : [|www.cleanenergycouncil.org.au] ) ** Typical plant site : **  1. Residential uses : The small solar panel will set up on the roof of houses and the cylinder is often installed ground  2. Commercial uses : Mixed technologies make it possible. Panels are installed on the hill or some sunshine ground to collect heat to centralized cylinder. **Typical plant costs** :  - In the United States, a typical system costs $4000–$6000 retail ($1400 to $2200 wholesale for the materials) and 30% of the system qualifies for a federal tax credit + additional state credit exists in about half of the states. **Typical plant** **running** **costs** : It is nearly Zero cost to run this technology. However, it will not work efficient during rainy season and cloudy weather. || 13kwh/sqm (in the mid of cloudless day) || Absorbing solar panel would not be operated with 100% efficient. || Developed technology can track the solar energy so that panel will turn around to capture. || High cost problem for residence (The plant cannot provides energy as the high cost of installation and operation.) || Created heating from this plant cannot storage over usages. If don’t use, it is wasted. || Can it transfer over-charged energy to other place as solar PV does? || Sun flame – may affect to storage failure as great number of energy store at one time? || Increase percentage of sustainable energy dependency || Shortage of energy as other plants are closed? ||
 * Introduction **
 * || **Strength** || **Weakness**  || **Opportunity**  || **Threats (risks)**  ||
 * Sustainable energy generating. || Cannot generate electricity itself || With other technologies, it can provide electricity. Such as Solar PV and turbine engine. || Weather dependency  ||
 * Reduce CO2 from residential energy consumption || Without well predicted plan, it has many opportunities of power failure. || -Reduce energy consumption for heating and cooling from residential which is one of the biggest energy customers if there are other stable electricity providers for backing up the power failure.  || Failure of promotion to residences due to cost of installation.
