Valentin Software TSOL Overview

This is a dynamic simulation program for optimizing and calculating solar thermal systems. You can optimally design your planned solar thermal system, dimension storage, and collector arrays (east/west roofs) and determine the economic efficiency. You have many relevant systems for domestic hot water heating and heating support, 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, detailed simulation, and profitability results. This report also contains all the data necessary to be recognized as evidence by BAFA.
