Solar thermal products

Solar thermal systems convert solar radiation into heat and thereby make an important contribution towards avoiding fossil fuels. Demand for cost-saving and sustainable thermal systems is great, but the market is growing increasingly. DIN-Geprüft and Solar KEYMARK certifications are important reasons for your customers to choose your products.

We test and certify your thermal solar products for their performance, reliability, safety and usability. If they comply with the standards, you will be awarded two quality marks that demonstrate product quality and are recognized throughout Europe: “KEYMARK” and “DIN-Geprüft.” Our certification is suitable for a variety of products:

• solar collectors (flat plate collectors, tube collectors, PVT)
• prefabricated or custom solar thermal systems
• storage water heaters
• control equipment for solar thermal systems

The Solar KEYMARK certification unifies European quality standards and allows you to access the European market. Our certifications make it easier for planners, installation technicians and consumers to choose to purchase your quality products.

The certification program was developed with the involvement of manufacturers, test labs, certification bodies and the European Solar Thermal Industry ( ESTIF ). The Solar KEYMARK and "DIN-Geprüft" certification mark are issued in line with the following European standards:

• DIN EN ISO 9806 “Solar energy - Solar thermal collectors - Test methods”
• DIN EN 12975-1 “Thermal solar systems and components - Solar collectors - Part 1: General requirements”
• DIN EN 12976-1 and DIN EN 12976-2 “Thermal solar systems and components - Factory made systems”:
  
  • “Part 1: General requirements”
  • “Part 2: Test methods”
• DIN EN 12977-1, DIN EN 12977-2, DIN EN 12977-3, DIN EN 12977-4 and DIN EN 12977-5 “Thermal solar systems and components - Custom built systems”:
  
  • Part 1: “General requirements for solar water heaters and combisystems”
  • Part 2: “Test methods for solar water heaters and combisystems”
  • Part 3: “Performance test methods for solar water heater stores”
  • Part 5: “Performance test methods for control equipment”

The manufacturer must also perform product-specific manufacturing product control under consideration of the elements of standards series EN ISO 9000.

Quality criteria for testing solar panels:

• Internal pressure resistance, mechanical resistance and impact resistance
• Resistance to high temperatures, to internal and external thermal shocks, and to heat output
• Exposure and rain-resistance

Additional tests for thermal solar plants:

• Suitability for drinking water
• Frost resistance and over temperature protection
• Return flow protection
• Pressure resistance
• Safety equipment

The Solar KEYMARK certificate is valid for five years and can be extended by another five years upon application. The extension will be granted only if factory inspections are performed every year and physical inspections every two years. Once you have passed the certification, you can mark your products with the Solar KEYMARK and the "DIN-Geprüft" mark.

With our experienced experts, we are the right partner to provide neutral testing and certification for your solar thermal products. With the internationally recognized Solar KEYMARK and "DIN-Geprüft" test marks, you can stand out from the mass of providers and sell the quality of your products throughout Europe with a standardized quality mark. Our database lists you as a certified business and allows the latest technical data for your product to be viewed.
