This is how the KOSTAL Solar Plan works

The new online version of the KOSTAL Solar Plan is a piece of free configuration software that installers can use to optimise the planning of solar systems for customers.
Individual system and customer data are entered and the KOSTAL Solar Plan creates a recommendation for the appropriate system components from KOSTAL.
The KOSTAL Solar Plan takes account of what is possible from a technical standpoint and presents the key figures relating to energy and finance.
The new online version of the KOSTAL Solar Plan is easy to use via a PC or laptop as well as on a smartphone or tablet.

KOSTAL Solar Plan: the right choice for every system
The KOSTAL Solar Plan can be used to plan holistic solutions from everything from small PV systems to large-scale systems. KOSTAL components, such as inverters and energy meters, can also be used to integrate compatible battery storage systems and, in the future, that will include heat pumps and charging solutions too.

Holistic
With the free KOSTAL Solar Plan, you can lay out your system in just a few steps.
Simple
With the free KOSTAL Solar Plan, you can lay out your system in just a few steps.
Comprehensive
Presentation of all important key figures relating to energy and finance, such as the self-consumption and self-sufficiency potential as well as the possible savings of the PV system
Quick
Enter the system and customer data in just a few clicks and receive a customised PV system with inverter and storage system
Flexible
Worldwide location selection, access via web browser for PC, tablet and smartphone, automatic suggestions or manual layout of KOSTAL components, all important information can be individually selected in the report
Smart
The achievable outputs are determined on the basis of the system location and the orientation of the PV generator. A sensible way of connecting the individual strings on the inverter is output.

FAQ
By providing the KOSTAL Solar Plan planning tool as a web application, KOSTAL Solar Electric GmbH is simplifying the work of system planners and supporting them in finding the optimum KOSTAL inverter for every PV system. The layout 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 comprising PV modules and inverter. KOSTAL Solar Plan provides all the relevant data and presents key figures relating to energy and finance, such as the self-consumption rate, the degree of self-sufficiency and various other parameters, including remuneration and savings on electricity costs.
Copy URL to clipboardKOSTAL Solar Plan is aimed at installers, solar technicians and system planners who plan, install and commission PV systems. Solar Plan allows users to create projects quickly and easily, although expertise is required to use it. The system planners should have the following qualifications:
- knowledge of how an inverter works and operates
- knowledge of the relevant laws, standards and guidelines
To be able to access the KOSTAL Solar Plan web application, you need a company account in the KOSTAL Solar Terminal and must be assigned the "Planner" or "Admin" role. If you don’t yet have a company account, start by creating one (Registration for the KOSTAL Solar Terminal). The "Planner" role must be assigned to you by your company's administrator.
More information about the KOSTAL Solar Terminal can be found here: https://www.kostal-solar-electric.com/en-gb/solar-terminal/
You must fulfil certain requirements before you can log in to KOSTAL Solar Plan. Access to KOSTAL Solar Plan is only available to B2B customers. For this, you need a company user account in the KOSTAL Solar Terminal and must have been assigned the "Planner" or "Admin" role.

Copy URL to clipboardUsing the "Add PV module" button, a PV module can be added during planning both in the pop-up window (search for PV modules) and in the settings under "PV module database".
Furthermore, a data sheet for the missing PV module can also be uploaded. This will be added to the PV module database once it has been checked.
You will not be able to save a PV module that you have created yourself if the values entered are implausible or incomplete.
Copy URL to clipboardAny PV modules that you create are created and saved in a separate database. The "User" option must therefore be selected on the database. And this is where you will find the modules you have created yourself.
Copy URL to clipboardThe maximum over-allocation depends on the range set for the power ratio. You can define this using the "Min. power ratio" and "Max. power ratio" parameters.
Copy URL to clipboardThe dynamic power ratio takes into account both the system location and the orientation and inclination of the PV modules, meaning that the power ratio can be estimated with greater accuracy. This involves checking the maximum power that occurs simultaneously with surfaces with different orientations.
