The company was founded in 1988 by Dr. Ing. Gerhard Valentin and looks back on more than 30 years of company history. It started as an engineering office under the name of Dr. Valentin + Partner. T*SOL was the first software program to be launched on the market in 1993. In 1998 PV*SOL followed, the first version of our design and simulation software for photovoltaic systems, which established a long history of success.
Today Valentin Software GmbH with the software products PV*SOL, T*SOL and GeoT*SOL for dynamic simulation, design, yield and economic forecasting of photovoltaic, solar thermal and heat pump systems is one of the leading providers of design software for sustainable energy supply. The company is led by the managing director Mr. Steffen Lindemann. The founder, Dr. Valentin, retired from active business in 2016 and has been the company's main shareholder since then.
Our software products are used by engineers, system designers, architects, installers and craftsmen from the areas of heating, electrical and building technology. We are very well represented on the German and German-speaking markets. With the support of our sales partners, we are opening up or expanding to many international markets.
All software products are constantly maintained, expanded and adapted to the latest market conditions. In addition, we offer fair maintenance contracts that guarantee constantly updated software and individual support from our customer support team.
