Solar heating

Solar heating
The Sunwe Balcony Solar Collector is a solar collector designed to collect heat by absorbing sunlight. The term is applied to solar hot water panels, but may also be used to denote more complex installations such as solar parabolic, solar trough and solar towers or simpler installations such as solar air heat. The more complex collectors are generally used in solar power plants where solar heat is used to generate electricity by heating water to produce steam which drives a turbine connected to an electrical generator. The simpler collectors are typically used for supplemental space heating in residential and commercial buildings. A collector is a device for converting the energy in solar radiation into a more usable or storable form. The energy in sunlight is in the form of electromagnetic radiation from the infrared (long) to the ultraviolet (short) wavelengths. The solar energy striking the Earth's surface depends on weather conditions, as well as location and orientation of the surface, but overall, it averages about 1,000 watts per square meter under clear skies with the surface directly perpendicular to the sun's rays.

Key features of the Sunwe Solar Collector.

1. Internationally certified product (EN12975 KEMARY SRCC)

2. Copper heat pipes for rapid heat transfer and freeze resistant.

3. Reliable, efficient, tri-element evacuated vacuum tubes

4. Easy plug-in installation

5. Maintenance free

6. Suitable for mains pressure water (up to 6bars, max. 10bars)

7. Corrosion resistant material (aluminum and copper)

8. Aluminum frame 2.0mm thickness

9. Black or Silver aluminum casing in good insulated

10. Stable solar conversion throughout the day

11. The best solar collector for domestic solar water heater systems

12. Ideal for commercial solar water heater applications

13. Comprehensive 10 years limted warranty (life time will be more than 15years)

The working principle of solar collector is very simple.

1. Solar Absorption: Solar radiation is absorbed by the evacuated vacuum tubes and converted into heat.

2. Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to header.

3. Solar Energy Storage: Water or water mix is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.
