Professional Solar thermal softwares

This section provide a list of professional and commercial solar thermal softwares.


Polysun is a software dedicated to professionals for solar thermal design and sizing.
It includes a large components database

Solar thermal energy software Transol is a tool for design, calculation and optimization of solar thermal systems. Transol does dynamic simulation easy (TRNSYS engine) through a user-friendly interface. This tool comes from an ambitious project developed by Aiguasol

F-chart is a solar system analysis and design program written by S.A. Klein and W.A. Beckman, the originators of the F-Chart method. It includes meteo database and database of various collector types (flat-plates, evacuated types...) and various system types :
- Water Storage

Simulation software for solar hot water solar systems (only

T*SOL is a simulation program that allows you to accurately calculate the yield of a solar thermal system dynamically over the annual cycle. 
With T*SOL you can optimally design solar thermal systems, dimension collector arrays and storage tanks, and calculate the economic efficiency.
It includes all relevant systems and company systems.
- Components : combination tanks, buffer tanks, domestic hot water supply,

TRNSYS is a flexible graphically based software environment used to simulate the behaviour of transient systems. TRNSYS is made-up of two parts. 
The first is an engine (called the kernel) that reads and processes the input file, iteratively solves the system, determines convergence, and plots system variables. The kernel also provides utilities that (among other things) determine thermo physical
