Solar thermal products

The Solar KEYMARK certification offers manufacturers of solar thermal products numerous opportunities for positioning and promotion in the European market. DIN CERTCO supports you on your path to certification.

Solar KEYMARK is a Europe-wide recognized quality label that provides consumers with guidance and builds trust. The following products can be certified with the Solar KEYMARK label:

• Solar collectors, including PVT
• Prefabricated and custom-made solar thermal systems
• Hot water storage tanks (solar storage tanks)
• Control devices for solar systems

Solar KEYMARK sends a clear message: "Tested and certified once - recognized across Europe!"

The established quality label enables efficient and standardized marketing of your solar thermal products in Europe. At the same time, it facilitates access to other international markets by promoting transparency and comparability of technical standards.

The collaboration between DIN CERTCO and ICC-SRCC provides a valuable foundation for establishing your solar thermal products in global markets. You benefit from:

• Unified testing and certification procedures for the European and North American markets.
• Enhanced market opportunities through combined certifications (Solar KEYMARK and ICC-SRCC OG-100).
• Harmonized quality standards that make your products internationally competitive.

Enable your products to meet recognized standards and position yourself successfully in global markets.

The certification content and procedures are defined in a specific European certification program, which was developed in collaboration with the European Solar Thermal Industry Federation (ESTIF), the CEN (European Committee for Standardization) and other European certification bodies.

The testing standards for certification and the issuance of the Solar KEYMARK in combination with the "DIN-Geprüft" certification mark are based on the following European standards:

• DIN EN ISO 9806 "Solar energy - Solar thermal collectors - Test methods"
• DIN EN 12975 "Thermal solar systems and components - 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"

The Solar KEYMARK certificate is valid for five years and can be extended for an additional five years. The prerequisite for renewal is passing the annual inspections (Factory Inspection) and the biennial product testing (Physical Inspection). Upon successful certification, you can label your products with the Solar KEYMARK in combination with the "DIN-Geprüft" mark.

For the awarding of the Solar KEYMARK, DIN CERTCO conducts testing and monitoring processes supported by recognized independent testing institutes. In addition to product testing, on-site production control is audited to ensure consistent quality. After successful certification, the quality is verified through annual surveillance audits.

Benefit from the Solar KEYMARK certification, strengthen your customers' trust, and highlight your solar thermal products with a recognized quality label. DIN CERTCO is your reliable partner throughout the process.
