FAQs about the Photovoltaic Simulation Tool
FAQs about the PV Calculator
Which temporal resolution is used for the simulations?
The calculation is done for an entire year with a temporal resolution of 15 minutes, whereby fluctuations in consumption during the quarter hour periods are taken into account.
Can we also look at electric vehicles and space heating with the simulations?
Currently, it is not possible to examine electric vehicles and space heating with the free PV calculator; this function is only available to customers who purchase our web tool.
Which data is used as a basis for the simulations?
The PV yield data is based on data (PVGIS-SARAH) from the Photovoltaic Geographical Information Systems (PVGIS), assuming optimal (unshaded) conditions. PVGIS adjusts the database every few years to suit changed solar irradiation values. This is why higher average PV yields can be expected now than 10 years ago.
Why are there discrepancies of several percentage points between own consumption ratios across different online calculators?
The main reason behind this has to do with correct representation (and the know-how), especially of the storage device. Many calculators and simulation tools fail to take account of factors such as battery age, which – over a number of years – can make a substantial difference of 3-5% in the own consumption ratio.
FAQs about the PV Web plugin
What is the billing model for the simulation tool?
Besides the basic module, several additional modules are available. There is a package price for all modules which includes the licence costs for the 1st year. The monthly licence payments then accrue from the 2nd year. Alternative billing methods (e.g. based on the number of simulations done) may also be available. Get in touch with us to find out more!
How long am I bound to the contract for? How can I terminate the contract?
The licence for the first year is covered by the basic price. Beyond that, you are not bound to the contract – the licence terminates automatically if the contract is not renewed.
How is the NFSim web plugin installed on our trader platform?
We provide an integration template for your website. The implementation itself and the graphic fine-tuning must be done by the customers themselves. Of course, we are available to answer any questions which you might have!
In which languages is the NFSim web plugin available?
The NFSim web plugin template is currently available in German and English. Other languages are possible on request.
