Solar Collector and Solar Water Heater Manufacturer in China

Shenzhen Commonpraise Solar Company Ltd. was established in 1997, and is a Chinese manufacturer of solar powered products. Some of our popular items are the flat plate solar collector, solar air collector, air source heat pump water heater, flat solar water heater system, and hot water storage tanks. Commonpraise solar water heaters are ideal for supplying hot water in private residences, schools, factories, hotels, and more. In addition, our solar collectors are widely used in domestic and commercial solar water heater, heating systems, commercial and industrial HVAC systems, and more.

  • Flat Plate Solar Collector The solar absorber of this collector is welded by German ultrasonic welding machine. We provide customers with two types of solar absorber, namely the fin tube type and the plate tube type. The surface of the absorber uses the international patent of magnetron sputtering and selective coating, which possesses excellent adhesion. With a high absorptivity of more than 95% and a low emissivity of less than 5%, it provides high thermal efficiency. In addition, this equipment is resistant to corrosion and it possesses a long service life of 20 years.
  • Aluminum Tray Solar Collector
  • Aluminum Tray Solar CollectorAbove 92% transmittance and low-iron tempered glass is used in the glass cover of this high strength, safe and reliable aluminum tray solar collector.
    The copper tube and copper fin of this equipment is welded by ultrasonic machine made in Germany or laser welding machine.
    The adoption of one-piece aluminum sheet in the back plate and frame of this facility ensures better effect of insulation. Its surface, handled by oxidation treatment, is characterized by long service life ...
  • Solar Air Collector
  • Solar Air CollectorSolar air collector makes use of solar energy to heat air. Our solar air collector is composed of a highly efficiency dual-layer absormer material, a selective surface with high absorptivity up to 75% to capture solar heat, temperature inductive probe, automatic thermal insulation air valve, air fan, indoor temperature controller, and more. It is a patented product with patent number of ZL 2007 2 0172469.9, and it is easy for installation and use. Solar air collectors can be divided into different types to heat either outdoor ambient air or indoor recirculated building air ...
  • Domestic Pressurized Solar Water Heater
  • Domestic Pressurized Solar Water HeaterThe solar collector is designed on the roof of this domestic pressurized solar water heater. The storage tank is installed, together with three different supplementary heating facilities, at the ground level.
    This equipment has altogether five main components, namely the storage tank, the solar collector, the circulating pump, the controller and the supplementary heating system. The storage tank is used for the storage of the heated water ready for domestic use. The solar collector absorbs solar energy to heat up water.

All Commonpraise solar powered products and parts are manufactured in our ISO9001:2008, ISO14001: 2004, and ISO14024:1999 certified factories. This enables us to meet the strict demands of our customers, while maintaining an eco-friendly operation. The society and our employee health are important to us at Commonpraise, so we are also GB/T28001-2001 Occupational Health and Safety Management System certified.

In order to ensure the quality of our solar collector, solar water heater, and other solar products, many quality control measures are implemented throughout production. For example, we only accept materials from approved suppliers, and we inspect all raw materials and components multiple times to ensure they meet our strict quality requirements. In addition, regular testing, cleaning, and maintenance of all equipment, as well as testing and training of staff, ensure production efficiency and that our solar air collector, air source heat pump water heater, and other products meet international standards. Specially trained quality personnel perform inspections of each production process to ensure all standards are met, from cleanliness to quality, and final inspections of our solar powered products are also conducted prior to delivery. Any non-optimum situations which are found are remedied by taking immediate steps to ensure they do not recur. As a result of our efforts, our flat plate solar collector, solar air collector, flat solar water heater system, and other solar powered products have received Solar Keymark, Standmark, SRCC, FCC, CE, CB, and CCC certifications.

We use advanced equipment, such as a gantry hydraulic press, Germany ultrasonic welder, vacuum coating equipment, and aluminum profile cutting machines, for our flat plate solar collector production, and we use a CNC hydraulic plate cutting machine, three-roller plate rolling machine, and more for the hot water storage tank and solar water heater production. This equipment is all computer-controlled and highly automated, thus reducing labor costs and improving efficiency. We acquire our copper, aluminum products, glass, and steel plate materials through suppliers with whom we have long-term relationships, which provides us quality products at reduced rates. All our solar thermal collectors, solar water heater and solar PV products are manufactured in strict conformation with our design drawings and related technical requirements, and a sample is created for inspection before mass production is begun, which eliminates waste. These factors all contribute to our lower costs, and thus the competitive prices we are able to offer our global customers on our solar collectors, solar water heaters, and other solar powered products.

Located in Shenzhen City, we are near international airports, railway stations, seaports, and highways. This convenient transportation allows us and our customers to save on shipping, and also enables clients to visit to us conveniently. Currently, our flat plate solar collector, air source heat pump water heater, and flat solar water heater system are exported to countries including Germany, Romania, Bulgaria, Canada, America, Australia, Saudi Arabia, Spain, Austria, Indonesia, Brazil, and Columbia, to name a few.
