| The Performance Characteristics and Application of Solar Modules |
Solar power is an abundant and renewable energy from the sun. Solar Photovoltaic Generation is an innovative and high technology, which can convert solar radiation or light energy into electricity. It's very clean, pollution free and renewable. Making full use of the solar power will promote the balance between humankind and the nature.
Solar power has a lot of advantages. It's safe and available everywhere without noise and pollution. Its systems, which have long lifetime, no matter in large or small scale, are easy to install and maintain. There is no need for fuel and guards. Besides, the equipments are easy to combine with the buildings without wire connection. All above mentioned advantages are unique for solar power, compared with the conventional ways to generate electricity.
Photovoltaic power will play a very important role in the way of electricity supply in China in the future. It's estimated that by 2010, the PV power will be up to 600MWp, 30GWp by 2020 and 100GWp by 2050 in China. According to China Electric Power Research Institute, the renewable power will take up 25% of the total electric power in China by 2050, 5% of which will be photovoltaic power. |
| （ 1 ） Introduction of the Principle: |
A solar battery is a kind of semiconductor which can convert solar energy into electricity. The principle is that when the sun light meets the PV panel, electric current and voltage will appear. So photovoltaic (PV) is the technology of converting solar radiation or light energy into electricity directly. The solar power systems consist of PV arrays, charge controller, storage batteries, DC/AC inverter and so on. The following chart is an illustration of the system:
 |
| 1. |
For residential use
(1) Continuous loads of 10W to 100W for remote districts without electricity, such as altiplanos, islands, pastures and frontier defence stations, used in lighting, TV and radio, etc.
(2) Power systems for continuous loads of 3KW to 5KW, located on the roofs.
(3) Solar water pumps used in deep water wells. |
| 2. |
For traffic use.
Lanterns, traffic/railway signal lamps, traffic caution/indication lights, street lamps, upper air indicators, freeway/railway wireless telephone boxes, nonguarded crossing station electricity supply and so on. |
| 3. |
For communication or correspondence use.
Nonguarded solar microwave relay stations, fiber maintenance stations, broadcasting / communication power systems, mini communication machinery, army GPS and so on. |
| 4. |
For oil, ocean and weather use.
Solar power systems to protect oil pipelines and reservoir strobes, daily life lighting and emergency power around oil well areas, sea surveying equipments, hydro meteorological observation facilities, etc. |
| 5. |
For lighting use.
Yard lights, street lamps, portable lights, camping lights, mountaineering lamps, black light lamps, LED lights, energy-saving lights and so on. |
| 6. |
For PV power station use.
Independent PV power stations for continuous loads of 10KW to 50MW, wind & sunlight (diesel oil) power stations, various large parking lots charge stations, etc. |
| 7. |
For solar building use.
It's a trend to combine the solar power with the construction stuff so that electricity self-support will be realized. |
| 8. |
In other fields:
(1) Used in cars: electromotive motor, battery charge equipment, car air conditioner, ventilator and refrigerator, etc.
(2) Regenerated solar hydrogen power systems.
(3) Electricity-supply for sea water desaltification facilities.
(4) Applied in satellites, aircrafts and solar power stations. |
