Document the high quality standards of your solar thermal products with the Solar KEYMARK
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.

Secure the confidence of European customers with testing and certification for your solar thermal products
Strengthen your customers' and business partners' trust by asking us to certify your solar thermal products. Our two neutral and internationally recognized test marks highlight this difference for your customers and offer them a valuable aid in decision-making in a constantly growing market. Certification is the basis for the awarding of subsidies and the improved sales opportunities they bring. This will help you stand out in the competitive environment.
Solar KEYMARK certification testing criteria for your solar thermal 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
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
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.
