On the Best Practice Implementation of Solar Thermal Obligations. The ProSTO EU Project and the Portuguese experience

Author(s) : Prates, Manuel João Lopes , Mendes, J. Farinha , Carvalho, M. J.
Description : Based on the work that it is running within the ProSTO EU project (http://www.solarordinances.eu/), this paper presents a tentative approach to the best way for a successful implementation of a solar thermal obligation (STO) in a community. The EU framework, and base line assessment – including succ...

Solar thermal collector yield: experimental validation of calculations based on steady-state and quasi-dynamic test methodologies

Author(s) : Horta, Pedro , Carvalho, M. J. , Fischer, S.
Description : The characterization of collector efficiency is the fundamental tool for long term calculation of collector yield. It is, thus, one of the most important inputs in software tools aiming the design of solar thermal systems. Presently two test methodologies are available for characterization of the ef...
