Online Calculator

The Solar Payback Online Calculator provides a simplified way for 5 cities in different regions in each country to assess the economics of heat production with conventional fuels in comparison to solar thermal based heating alternative. You can either use default technical / economic values or insert your own values for most of the calculations. For further explanations, please go to the TOOL MANUAL.
