SOLAR Energy – It’s uses and How the Systems Work
By Ingrid Tsang
2
Uses Heating Water Heating Spaces Cooling Spaces Producing Energy
Lighting Ventilation Drive Vehicles Distill Water Influence architecture, urban designing Agriculture, horticulture
3
Heating Water Solar thermal systems
Starts with collector: absorbs radiation, turns it into heat Heat carrying liquid: carries heat to the hot water tank Tubes: when need of hot water, carries to needed area
4
Producing Energy Photovoltaic systems: more complicated
Electric charges – made when sun shines on the solar panel Electric currents – can be used around the house Positively charged layer of silicon against negatively charged layer of silicon: lets the electric charges pass through Conductive metal: concentrates charges into electric currents
5
Heating Spaces Can be classified as two modes – passive, active
No mechanical equipment Lets all the sunlight possible go inside Traps heat Active Uses special equipment – e.g.: like boxes covered with glass Air passes through the heated places
6
Example of solar Energy Use in HK
Along North Lantau Highway
