There are three scenarios when these categories are not displayed in your project’s analytics:

1. Your selected energy system is a GTI energy system, for which we do not provide these statistics.

2. You have selected Solargis Time Series or Solargis TMY P50 data instead of an energy system in the energy system selector. Time series data analytics does not provide this data since it is only PV energy system-related.

3. If your selected energy system is a PV system, it has not yet been simulated. You must simulate it to get this data.  

Yes, you can download your project data and use it in other PV data-supporting systems. We offer several formats, such as JSON, CSV, NREL SAM, Helioscope, and PVSyst data formats, to download your data. Read this guide to learn how to export your data.

Yes, you can generate a detailed report with all essential data, including charts and statistics. You can do it using the download section of your project, and you can learn how to do it here.

You can create an Evaluate project in two ways:

• By importing it from the Prospect application.

• Creating a new project from scratch.

Both methods are explained in detail here.

You can do it using the energy system selector at the top of your project overview page.

Your energy system is not simulated. You must simulate it to obtain its analytics data.

It is likely that you have used all your purchased project quota. To assign one to your project, you must purchase additional credits. To do that, please contact your Solargis account manager.

Details about how to work with the analytics section are outlined in the Data analysis document, and charts are explained in the How to read the charts document.

These details are found in your project’s PV statistics, PV system losses, and PV long-term degradation sections, respectively. More information on this topic is covered here.

Please remember that these are available for PV energy systems only. Our system does not provide such information for GTI energy systems or Time Series data.

You can create energy systems from your project's details page.

1. Open the project where you want to add an energy system.

2. Use the main navigation to the left to switch to the Project section and select the Energy system.

3. In the alternative energy system tab, click the “Create” button and select the system you want to create.

You can find more details about this procedure here.

You can create identical energy system using the duplicate feature. This way, you can quickly create alternatives with subtle changes for comparison.

Yes, you can change your preferred dataset for simulation in the energy system’s general settings tab. However, if your energy system has already been simulated, the analytics data will no longer be valid, and you will need to simulate it again.  

If you want to keep your original project’s data, you can duplicate the energy system and change the dataset in the new one. This will give you the benefit of having two identical energy systems with different datasets used for simulation.

No, the system applies the changes and recalculates the system’s parameters automatically after every value change.

You can add an array to your project in the following ways:

• To the reference point on the map - a 1MW square area array will be added by default.

• To a segment - the array will fill the entire segment area, following its shape.

You can directly set the power output of arrays placed at the reference point only (not in a segment).

1. Select the array you want to change in the left navigation under the System design category or by clicking the array on the 3D map

2. Under general settings of the array’s properties, enter the required power output. The design on the map will update automatically.

For arrays in segments, there are steps you can take to get closer to your desired PV power output:

• Change your inner safe zone in the segment.

• Change the distance between tables.

• Select a different PV module (with a different power output).

• Adding restricted areas to the segment (will reduce the number of tables in

Yes, you can connect your arrays to any existing inverter setup. Please ensure the inverter setup can withstand the connection of the new array and that the new parameters are within its power limits.

Yes, you can resize the existing segment containing an array. 

1. Open the segment options menu by clicking its three-dot menu in the main navigation panel to the left.

2. Select b from the menu.

3. Grab and move any vertice with your mouse to the required position.

4. When finished, hit enter on your keyboard or double-click the mouse to save and recalculate the segment.

Your segment will be adjusted, and the array will fill the n

You can do it by creating a restricted area.

Yes, you can create paths inside your array using the restricted lines. 

Yes, there are options you can use to change the placement of your inverters.

Generally, inverters can be placed under the tables or positioned as standalone outside of the array. You can also place your inverters in restricted areas or lines for better accessibility.

You can use the move tool on the 3D map's toll panel.

Yes. Go to your array’s properties panel and change it under the general tab’s array type property.

Please keep in mind this will reset most of the array settings, including the PV module selection.

Right now, the energy system configuration does not support cabling.

This is a planned feature and will be available in the future.

Not at the moment. In the first planned iteration, we would like to allow the import of terrain data as a consultancy service. Later, we plan to support uploading terrain datasets within the Solargis Evaluate environment.

Solargis Evaluate offers the following terrain options:

• Flat - without the terrain.

• Copernicus in 30m resolution (1 arcsec | global | 2011-2015 | surface model - including trees and buildings).

• SRTM (Google Earth) in 30m resolution (1 arcsec | global | 2000 | terrain model - excluding trees and buildings).

• SRTM (Solargis) in 90m resolution (3 arcsec | global | 2000 - 2017 | terrain model - excluding trees and buildings).

Not at the moment, but it is possible to find free map sources in “Map tile” compatible format, which can be added as a service to the energy system designer as a custom map layer and get fresh satellite imaginary or other interesting local layers such as local cadastre, safe zones, protected areas, etc.

You can create a free account and upload your component to the PV components catalog, then select it when changing a PV module in the PV array properties.

Remember, there is a validation process when creating PV components in the PV components catalog and it may take some time until your own component will become available for selection.

Currently, the cable losses are defined as percentage values for:

• DC cabling

• AC cabling after the inverter

• AC cabling after inverter transformer

• AC cabling after power transformer (optional)

Default values are applied for all of these losses.

Hint: Our simulator supports exact losses calculated based on the resistance of the cables, where the inputs are:

• cable length

• cable material

• cable diameter

The cable length information is currently missing. Once we will introduce cabling, the losses will be precisely calculated based on real design.

No, this feature will come first for fixed tilt early next year (2025) and for trackers later.

Yes, there is support for two levels of transformers that can automatically fill the voltage gap between the inverter voltage output and Grid connection voltage.

Yes. Although a dedicated mounting type is not yet available, it is possible to use standard fixed one-angle mounting with a 90-degree tilt. Tables will be placed in the inclination of the segment. Visible rack construction will not obstruct PV modules in simulation.

This is a restriction we have introduced for a better user experience on computers with limited processing power. It does not affect the simulation in any way. It is only a visual restriction to lower the rendering burden on your machine and ensure smooth performance. It is usually applied to designs with output higher than 20MW.

This may happen for many reasons, most of which are out of our hands.

Some details about why this happens can be found on the following links:

What can I do next?

Usually, the PV energy system editor will restore the context on its own, and you can continue working. If it does not, you must refresh the page. If that doesn’t help, you’ll have to close and reopen the whole browser. After that, everything should be back to normal.

Can I prevent it from happening again?

Generally, you can follow these steps to minimize the chance of it happening again:

• while editing the PV energy system, close other unnecessary tabs and programs that may be taking up your PC resources

• if you have a dedicated GPU on your PC, make sure the browser is set up to use it

• make sure your browser is up to date

• make sure your drivers are up to date
