Simulation guide

Everything you need to know to get a production and cost estimate without drawing anything

What is Simulation?

A simulation is a quick tool that allows you to get an estimate of production, costs, and savings by entering a few numerical data points, without having to draw the system on the map.

Difference from configuration

Unlike configuration, simulation is a purely mathematical calculation and does not account for the actual roof geometry (obstacles, slope shape, available space).

It is ideal for a fast production and economic estimate, but if you need precision on panel positioning (especially if there are many relative to available space), we recommend using the Configurator.

How to perform a simulation?

To start a simulation, follow these simple steps:

Enter address and location

Enter the full address (street, number, city, and zip code). A map with a marker will be displayed.

In this mode, it is not essential for the marker to be exactly over your building's roof, because the system will not analyze its shape. What matters are the geographic coordinates (latitude and longitude) to calculate the solar irradiance of the area. If the position is very different, you can correct it by clicking the desired point on the map.

Map with marker — Figure 1: Address entry and marker verification on the map

Power setting

Unlike graphical configuration, here you must set the system power you want to simulate (in kW).

If you don't know the suitable power for your needs, you can use the integrated utilities (Calculate Power) which suggest the ideal value starting from your bill or the appliances you use.

Power setting — Figure 2: Manual power setting or use of calculation utility.

Panel selection

Choose the panel you want to simulate. You can opt for a generic panel, one from a company present on Sunnix, or enter a custom panel with its technical specifications.

Generic 430W Panel: Choose from panels of companies on Sunnix
Manual:: Enter custom technical specifications

Panel choice — Figure 3: Selection of panel type (Default, Database, or Manual).

Orientation selection

You must indicate the roof orientation:

Suggested (Default): Calculates production estimating the absolute best orientation and tilt for that geographic zone (maximum theoretical yield).
Real: If you know your roof's exposure, we recommend modifying this option by selecting the orientation most similar to reality for a more reliable result.

Start calculation

Once parameters are defined, click the calculate button located at the bottom.

What happens now?

Sunnix will process the input data and show you an estimate of annual and monthly production, number of panels needed, area occupied, and, if available, total panel cost. You can then explore the summary to add extra components (inverters, batteries, incentives) and see how costs and economic return change.

Estimated time: 30 seconds
