We will be back at Intersolar Europe in Munich to present our innovative design software for photovoltaic, solar thermal and heat pump systems. From 7 to 9 May 2025, you can find out about the latest program versions of PV*SOL, T*SOL and GeoT*SOL at our booth A4.331.

With PV*SOL premium, the industry standard for PV system design, you are always up to date: the current version takes Germany's “Solar Peak Act” into account, which regulates the non-remuneration of electricity in the event of negative exchange prices. After entering a forecast of the affected yield hours, PV*SOL determines the compensation period according to § 51a EEG and integrates this into the profitability analysis. If the new law is applied retroactively for 2024, for example, around 18% of the yield would be affected.

The heat pump software GeoT*SOL has also been further developed. The new feature for dimensioning air, water and ground-source heat pumps makes selecting the right system even easier. A clear diagram shows the building and heat pump characteristic curve, the bivalence point and additional heating systems such as boilers or heating rods. This allows you to quickly see up to which outdoor temperature the heat pump can heat the building alone and when additional heaters will support or fully replace it.

Live design sessions with PV*SOL premium will take place regularly at the booth and our expert team will be available for product advice on all days. This year, the international sales partners Solsta SAS (Colombia), Switch2Solar (Netherlands, Belgium, Luxembourg) and Zolw AS (Norway) will be on site. Exclusively for Intersolar, all trade fair visitors will be offered an attractive trade fair discount on all commercial user-based licenses for PV*SOL, T*SOL and GeoT*SOL.

Meet us at booth A4.331 - we are looking forward to your visit!
