There are many energy efficiency labels around nowadays. They tell the consumers how much energy items like refrigerators, washing machines and light bulbs use, or - in the best case scenario - how little. The ErP label for "energy related products", with categories ranging from a red D to a green A+++, is the most well known.
However, even though energy labelling has now also been mandatory for heating products since 26 September 2015, those who want to know about a solar thermal system has so far had no luck. Since solar collectors do not consume any energy but solely generate heat, they are not currently labelled.
Well-known manufacturers are now implementing their own label so that consumers can be informed when choosing a product on the market that best meets their requirements for an environmentally friendly and sustainably cost-effective heating supply.
If a person chooses a solar collector, their main objective is to save primary energy and therefore costs. A good collector can cover up to 50 percent of a consumer's hot water and heating needs - and, at the same time, protect the environment. However, this is only possible if the collector actually generates high outputs.
Trust is good - tested and registered solar outputs are even better!
In order for consumers to be well informed and thus make a conscious decision, the heat yields of the different collectors must become comparable for potential buyers. For this reason, well-known system and component providers, suppliers and associations have joined forces to form the Solar Heating Initiative (SHI) . The common goal with the Global Solar Certification Network (GSCN) is the worldwide uniform labeling of solar collectors with the voluntary collector label SOLERGY.
It offers consumers the opportunity to select from the range of different collectors the one that delivers the most suitable yield for them. The data sheet for a valid Solar KEYMARK certification serves as the basis for Europe. In the collector label SOLERGY, all classifications are highlighted in green, a symbol that solar collectors, as the most environmentally friendly heat suppliers, are basically ecological and efficient.
Basic registration information
The basis for registration is the DIN CERTCO Certification Scheme "Collector Label SOLERGY". The documents listed below form the basis for checking and registration The relevant copy is only valid for dated references. For non-dated references the respective current edition of the related document including any changes is valid.
- Valid Solar KEYMARK certificate and Solar KEYMARK data sheet
- the General Terms and Conditions of DIN CERTCO
- DIN CERTCO's corresponding schedule of fees
Applicants can be both manufacturer and seller of solar collectors with a valid Solar KEYMARK certificate or those who have already applied for certification with Solar KEYMARK.
The applicant must submit the following documents to DIN CERTCO:
- Application for registration for the collector label SOLERGY in its original copy and with a legally binding signature
- current valid Solar KEYMARK certificate for the said product
- the completed Solar KEYMARK data sheet (ScenoCalc at least version 2.0)
- the completed Input Excel form (template from DIN CERTCO)
After submitting an application, the applicant will receive an order confirmation from DIN CERTCO with a process number and further information on the procedure and, where necessary, the application documents which are still to be submitted.
On the basis of the application documents submitted DIN CERTCO shall perform an evaluation in the form of a plausibility check, a data check, a yield check with ScenoCalc and registration of the label class.
The conformity evaluation is only performed on the basis of an absolutely certain and accurate Solar KEYMARK data sheet or an absolutely certain and accurate Excel form provided by the applicant.
The information included in the Excel form shall be checked by DIN CERTCO with the current Solar KEYMARK data sheet and then forms the basis for the registration of the collector yield label with the corresponding label class and the creation of the optional collector yield label.
If errors and/or uncertainties are identified the applicant must resubmit a corrected data sheet or Excel form.
Registration and Publication
After the submitted application documents have been successfully checked and a conformity assessment, DIN CERTCO carries out registration and grants the right of use for the Collector Label SOLERGY in connection with a corresponding register number (format of register number: ELxxxx)
Furthermore a collector label (50/75 °C and 25/50/75 °C) with the determined collector output for the output classes 25 °C, 50 °C and 75 °C is created and given to the applicant.
DIN CERTCO keeps a record of all solar collectors registered with the Collector Label SOLERGY incl. their collector output and output classes, updates this record and makes it accessible to the public. All registered collectors can be retrieved on a daily basis via DIN CERTCO's homepage.
