Whether the use of solar energy pays off or not has long since ceased to be a question for people who think in a wider context. The CO2-free use of energy is a matter of urgency in view of massive environmental damage and global warming of the earth's climate. Those who pay attention to quality when purchasing solar panels are not only acting in a way that benefits the environment - they will also be rewarded with tangible savings.  A consistently effective solar panel provides a source of useful energy sometimes way beyond its amortisation period. Areas of application are old as well as new buildings and can include domestic hot water use as well as supplementary heating systems. We at Intemann would be pleased to discuss all the different possibilities with you.
