The solar Keymark

The main quality label for solar thermal

The Solar Keymark is a voluntary third-party certification mark for solar thermal products, demonstrating to end-users that a product conforms to the relevant European standards  and fulfils additional requirements. The Solar Keymark aims at reducing trade barriers and promote the use of high quality solar thermal products in the European market and beyond. It is used in Europe and increasingly recognised worldwide.

The Solar Keymark is a CEN/CENELEC European mark scheme, dedicated to:

• Solar thermal collectors,
• Solar thermal systems, storages and controllers.

Benefits of the Solar Keymark

What are the benefits of the Solar Keymark for consumers

• high quality products,
• guarantee that the product sold is identical to the tested product,
• confirmation that products are FULLY  tested according to the relevant standards,
• eligibility for subsidies.

What are the benefits of the Solar Keymark for manufacturers simpler testing procedure, one test valid for all European countries, freedom of choice amongst the accredited test labs, easier introduction of new products in different European countries, simplified procedures for replacing components in certified products.

Why choosing certified products?

The experts’ experience speaks about numerous unsuccessful solar thermal projects, where manufacturers invested extensive sums of money to produce products without the expected results.

Therefore, it is necessary to allocate a careful attention to all steps during the development of the project and its implementation. The choice of a reliable and effective collectors, as well as other important components of the system, is an important first step. The Solar Keymark aims at certifying the quality of your products as well as providing you with a key advantage on the market.

What is the Solar Keymark?

The Solar Keymark is a voluntary third-party certification mark for solar thermal products, owned by CEN/CENELEC.

Every certified product is in full conformity with the relevant European standards and fulfils additional requirements to assure constant quality. This level of quality is maintained by initial type testing and by regular controlled of the products and their production sites by independent inspectors. Consumers and authorities can fully rely on the certified products.

For these reasons the Solar Keymark is the basis for most European supporting schemes and it is also increasingly recognised or adapted worldwide.

The Solar Keymark can be currently granted to:

• Solar collectors (according to EN 12975-1)
• Factory made solar thermal systems (according to EN 12976-1)
• Custom built solar systems thermal systems: solar water heaters and combisystems
• (according to EN 12977-1)

How to recognise a certified Solar Keymark product?

Solar Keymark’s certified products bear the official Keymark logo together with an identification code.

Registered Code

Registering and comparing of certified products

In the Solar KEYMARK database, all certified products are listed with the links to the manufacturer’s website and the data sheets of the product’s performance parameters.

The performance measurements and calculations utilise sophisticated mathematical apparatus and provide a model of solar collector’s or system’s behaviour in different conditions. This offers a very powerful tool for comparison of different products and (with respect to other facts like the prices, availability of the products, references about their manufacturers, etc.) gives you – or your designer, planner, architect, or developer – a good chance to choose the really best fitting solution for your specific needs, requirements, and conditions.

Solar Keymark Network

The Solar Keymark certification system is managed by a group of empowered certification bodies, recognised testing laboratories, quality-conscious manufacturers and Solar Heat Europe: The Solar Keymark Network.
