  • What is solar energy and how does it work in a solar water heater device?

    Solar energy is a renewable energy from the sun. It is an important source of energy because of the vast amounts of energy that are freely available, if harnessed by modern technology. The solar collector is the engine of any solar water heater. There are a few type of solar collector and solar vacuum tube is the most efficient type which provide the greatest return on investment versus any others type of solar collector . The solar vacuum tube will absorb UV light of the sun and convert to heating energy . This will heat up water and the hot water can then be used for showering , space heating , industrial process etc .
  • Why SolarGold solar water heater?

    In contrast with other brands which uses solar panel to activate the solar water heater, our brand uses vacuum tubes to absorb UV from the sunlight and then generate heat to heat up water in the tank. The vacuum tubes guarantees hot water all year even in raining seasons or cloudy weathers. The diagram attached below shows the comparison between SolarGold and X Brand. Performance during weather

  • The Solar Vacuum Tube

    There are several type of solar water heater and vacuum tube is one type of the most efficient solar water heater. The vacuum tube comprises of an inner tube, an outer tube, a selective absorption layer, a vacuum space and absorption layer. The outer wall of the inner tube has the selective absorption layer, which absorbs 99% of the suns energy. Both inner tube and outer tube are made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to penetrate through with minimum reflection. The inner tube is coated with a special selective coating which features excellent solar radiation absorption and minimal reflection properties. The top of two tubes are fused together and the air contained in the space between the two layers of glass is extracted out while exposing the tube to high temperatures. This evacuation of the gasses forms a vacuum, which is an important factors in the performance of the vacuum tubes. This is exactly how a glass lined thermos flask work, a vacuum is an excellent insulator to minimize heat loss. Our high quality control SolarGold vacuum tube is durable and long lasting. We offer 10 years product warranty for our vacuum tubes. If you are looking at producing hot water with a higher temperature then heating with solar vacuum tubes will produce the best results.

  • SolarGold Intelligent Controller

    SolarGold is the only solar company which provide an electronic intelligent controller with each solar water heater in the market. The intelligent controller display the water temperature, water level contain in the hot water tank and also signal illustration for easy use. The intelligent controller is equip with manual and auto mode setting for water loading, back up heater etc. There will be a clear indicator if something goes wrong for ease of troubleshooting. With this intelligent controller, we now can easily monitor the actual operation condition.
