Description:
Flat plate solar collector is a device that absorbs solar energy from the sun and converts it into usable heat energy, the heat is normally absorbed by water in the loop, or a freeze-resistant water mixture, a kind of medium used to supplement hot water heating or house air heating.
1. Suitable for domestic, dormitories, parks, hotels, schools, public showers, swimming pools, restaurants and other sites requiring for large hot water use
2. The panel is of high efficiency and good performance
3. Suitable for open or closed Loop (glycol-water)
4. Suggest this type of solar collector for warm areas, for extremely cold
5.mounted on different building structure
2000 * 1000 * 80 MM Pressurized Black Chrome Coating Flat Solar Panel Working Principle
A typical flat-plate collector is a metal box with a glass or plastic cover (called glazing) on top and a dark-colored absorber plate on the bottom. The sides and bottom of the collector are usually insulated to minimize heat loss.
Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate.
Absorber plates are commonly painted with "selective coatings," which absorb and retain heat better than ordinary black paint. Absorber plates are usually made of metal typically copper or aluminum because the metal is a good heat conductor.
Copper is more expensive, but is a better conductor and less prone to corrosion than aluminum.
In locations with average available solar energy, flat plate collectors are sized approximately one-half- to one-square foot per gallon of one-day's hot water use.
Applications:
The main use of this technology is in residential buildings where the demand for hot water has a large impact on energy bills. This generally means a situation with a large family, or a situation in which the hot water demand is excessive due to frequent laundry washing.
Commercial applications include laundromats, car washes, military laundry facilities and eating establishments. The technology can also be used for space heating if the building is located off-grid or if utility power is subject to frequent outages. Solar water heating systems are most likely to be cost effective for facilities with water heating systems that are expensive to operate, or with operations such as laundries or kitchens that require large quantities of hot water.
unglazed liquid collectors are commonly used to heat water for swimming pools. Because these collectors need not withstand high temperatures, they can use less expensive materials such as plastic or rubber. They also do not require freeze-proofing because swimming pools are generally used only in warm weather or can be drained easily during cold weather.
While solar collectors are most cost-effective in sunny, temperate areas, they can be cost effective virtually anywhere in the country so should be considered.
Competitive Advantage:
1. Suitable for domestic, dormitories, parks, hotels, schools, public showers, swimming pools, restaurants and other sites requiring for large hot water use
2. Flat plate solar collector presents a tube plate structure with a high efficiency, pressurized, insolation resistant, reliable quality with 15 years lifespan.
3. Suitable for open or closed Loop (glycol-water) active solar water heating system.
4. Flat plate is suggested to be used in non-frozen area, in frozen area, it is suggested to be used in active closed loop system with anti-freezing liquid for heat exchange.
5. Easy installation on slope or flat roof with little maintenance needed.
6. The high absorption: αs ≥ 92%, low emissivity: εh ≤ 10%, daily thermal efficiency ηd ≥ 55%
