T*SOL is the simulation program with which you can calculate the yield of a thermal solar system. No matter whether for domestic water heating, heating support, swimming pools or process heat, with T*SOL you can optimally design your planned solar thermal system, dimension storage and collector arrays (also east / west roofs) and determine the economic efficiency.

At the start of the design process, you have a large selection of all relevant systems for domestic hot water heating and heating support, as well as for swimming pools and process heat. During the design, you will be supported with dimensioning suggestions and can use a parameter variation to find the optimal combination, e.g. of storage size and collector area.

After the simulation you will receive a comprehensive and appealing project report with all system data as well as detailed simulation and profitability results. This report also contains all the data necessary to be recognized as evidence by BAFA.

Product highlights

Graphic representation of the simulation results

The parameters of the simulation results such as energies, temperatures or volumes can be displayed graphically. You can choose between different display formats such as bar charts and line graphs. The time axis can be varied between a day and up to a year.

This offers many options for analyzing the system.

Simulation of the solar yield and the coverage of domestic hot water and heating

The dynamic annual simulation calculates temperatures and energies in time increments of one to six minutes. System parameters such as the efficiency and solar fraction are calculated from the simulation results.

Databases with solar collectors, boilers and storage tanks

T*SOL is delivered with an extensive database. This contains more than

• 4,000 collectors (flat plate collectors, tube collectors, air collectors)
• 5,000 heat generators (condensing boilers, wood boilers, pellet boilers, district heating, etc.)
• 600 storage tanks (combination and buffer storage, monovalent, bivalent, etc.)

There is also a large number of predefined load profiles (single and multi-family houses, industrial building, hotels, etc.) and a selection of fresh water stations and heat exchangers. You can create, edit and delete your own products.
In addition, manufacturers can have additional storage tanks, boilers, collectors, fresh water stations and heat exchangers added free of charge (contact: database@valentin-software.com).

More program details

Parameter variation

You can vary up to two parameters at the same time (e.g. collector area and storage volume) to find out the optimal values for the combination of target variables including “efficiency”, “solar fraction”, “additional energy” and “solar yield”. </ p >

Energy label

Since September 26, 2015, it has been mandatory for all manufacturers, dealers and craftsmen in the EU to label heating devices for space heating and hot water systems in respect of their energy use. T*SOL simulates the energy efficiency of solar thermal supported heating systems and generates the composite system label for you.

Over 200 pre-configured solar thermal systems

All components can be parameterized in detail or selected from the database.

• Domestic hot water
• Heating
• Swimming pool
• Process heat
• Large systems

Global climate data available

T*SOL provides you with the latest TMY data of the DWD (current state 2017, averaging period 1995-2012) for Germany and more than 8,000 further climate locations for the whole world based on Meteonorm 8.1. You can use the interactive map to conveniently select the climate data. Locations not included are interpolated using satellite data and neighboring ground measuring stations. The import of your own measurement data takes place via files in DWD, Meteonorm or WBV format.

Design and simulate solar thermal systems professionally

The optimization of solar thermal systems depends on many parameters. T*SOL helps to find the best possible combination of storage tanks, heat generators and collector areas. As control also has a major impact on efficiency, you can precisely set control parameters such as switching temperatures and sensor heights. The minute-by-minute simulation enables you to establish the solar yield as well as the exact requirments of the appliances.
