About KOSTAL Solar Plan

If a solar system is being planned, not only should the system work, it should produce as high a yield as possible. Without software support, such optimum planning is usually very time-consuming. That is why KOSTAL Solar Electric GmbH offers the free layout software KOSTAL Solar Plan for your KOSTAL inverter.

With the KOSTAL Solar Plan tool, KOSTAL Solar Electric GmbH facilitates the planner's work and supports them in finding the optimum KOSTAL inverter for each PV system.

The sizing is based on the technically feasible limits, which are determined individually for each combination of PV module type and inverter type.

Based on the user's specifications, the application determines the best combinations of several different string configurations consisting of PV modules, each with one inverter.

KOSTAL Solar Plan delivers all the relevant data and provides the most important energy and financial data, such as the self-consumption rate, the degree of self-sufficiency and various other parameters, including remuneration and savings on electricity costs.

INFO

The degree of self-sufficiency indicates the percentage of the annual power requirement that can be covered by self-generated energy.

The self-consumption rate shows the proportion of energy you use yourself in relation to the total energy generated.

The application works with global irradiation and climate databases and with a comprehensive PV module database that is regularly updated. The user's own PV modules can also be created.
