This section provide a list of free solar thermal softwares.
Kalkener's online solar simulation software allows calculating solar thermal water heating systems:
the sizing of its main components according to the monthly, weekly and daily hot water consumption profiles, the solar site survey, the shading, orientation and tilt losses, the optimal position of solar collectors located on sloped roofs, the annual solar energy production (taking in account losses) and its key profitability indicators, (IRR and NPV).
SHW is a simulation software for Thermal Solar Systems. It is a freeware for Research and Teaching use.
Designed from unit of Energy Efficient Buildings at the University of Innsbruck, Austria.
