KACOCALC Pro

KACOCALC Pro is a free, award-winning program designed for the professional design and simulated creation of photovoltaic systems. Using the radiation data based on average values for ten years, data from several hundred types of modules, and all KACO inverters, we are well placed to offer you the optimal system design.

With the various functions of this program, you can plan the design of your entire PV system, either using the data of the modules already included in the program or data that you include by yourself. In addition, you also have the chance to gauge dimensions for the AC and DC cables, including the calculated loss for single and three-phase grid-tied systems as well as forecasting the anticipated production statistics.

The program is available in German, English, Spanish, Italian, Czech and French. It runs on Microsoft Windows.

PV System Design
Based on the module type and the number of modules you can find out which KACO inverters are best suited for your system. Consideration is made of the performance of the module in comparison to the inverter output, the MPP voltage with high module temperatures, the no-load voltage with low temperatures, as well as the system voltage of the modules.

Yield
The average yearly irradiation for representative locations is included. Along with the irradiation, the arrangement and installation angle of the modules are accounted for to calculate a projected yield. The projected yield is a conservative estimate, which is likely to be exceeded during actual operation.

Inverter Design
For larger quantities of a specific module type, the program tells you how many modules and strings you can connect to each single inverter.

Cable Loss Calculation
The cable loss calculation is divided up into three subgroups: DC cable loss, AC cable loss and AC three-phase cable loss. This function allows you to calculate the cable losses individually. For cable losses on the DC side, generator junction boxes can also be taken into consideration.

PV Modules
All current PV modules are already included in a list that is kept fully up to date. Should your module not be included in the list, you can use an entry form to easily add new modules. These user-defined modules remain present with subsequent updates.
