Three labels in Europe – what are the differences?

Submitted by Baerbel Epp on June 22, 2018
collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right)Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to market players as well as customers. The chart above shows the two voluntary collector labels Solergy (left) and Solar Keymark (centre top) as well as the EU Energy Efficiency label (right) which is obligatory for water, space and combi heaters under the Energy Labelling (ELD) and the Ecodesign (EDD) Directives  since September 2015.

Barriers to Technology Diffusion: the Case of Solar Thermal Technologies (2006)

Submitted by Hans Craen on March 27, 2009

This joint paper from the OECD and IEA (October 2006) looks into the different barriers that exist which prevent solar thermal technologies to deliver its real potential. Next to listing the barriers, the document also looks into means to overcome these, the existing technologies & markets and identifies best practices which can be used by policy makers in both industrialised and developing countries.

Three barriers to diffusion are analysed in more detail:

(1) Technical barriers,

(2) Economic barriers and
