Data analysis

In this document

We will introduce you to the project analysis section and explain how to work with it.

Project data analysis

The Analysis section is the main component of the Evaluate application. It provides detailed information about solar, meteorological, and environmental data related to your project. It also provides the PV statistics, losses, and long-term degradation analysis for selected PV energy systems. The analysis section is your key to establishing the feasibility of your project.

The solar resource data is directly related to the selected dataset/energy system, and the values displayed depend on several factors, such as shading (horizon) or, in the case of an energy system, installation angle.

The meteorological (Climate) and environmental (Environment) data are location-related and do not change regardless of the selected energy system. They are calculated automatically after the project activation.

PV statistics, PV losses, and PV long-term degradation categories depict the performance and losses of your PV energy system once it has been simulated.

Energy system selector and displayed data

The energy system selector lets you select the data you wish to display and analyze.

  • You will have access to the default location data after the project activation.

  • Once you create an energy system and simulate it, you may select it to display its related data. The analyst data for energy systems are different from location-only data, affected by the energy system’s parameters.

  • Additionally, PV statistics and losses are also shown for PV energy systems.

  • Parameters such as the type of the system/dataset, data type, and calculation status are displayed next to the selector.

What you select in the energy system selector directly determines the data, its granularity, and the categories displayed in the Analysis section.

Default location data

The default analysis data are marked with theicon and represent the default location data. They cannot be edited.

  • For an Early stage, only Solargis TMY P50 data will be available (yearly, monthly, and hourly statistics based on 15-minute data).

  • For a Full evaluation, you gain access to additional Solargis Time Series dataset containing detailed location data with the highest granularity available (up to 15-minute data).

The identical climate and environment data will also be shown for all non-calculated energy systems. In this case, the solar resource data category is omitted.

Energy system-related data

If you select one of your simulated energy systems (GTI or PV), related analysis data will show.

If you select a PV energy system, the PV Statistics, PV System losses, and PV long-term degradation categories will also be available. These two categories are not available for GTI energy systems.

The data charts and tables

Every category presents the data in the form of charts and tables.

Charts give you a visualization of the data to spot patterns or extremes quickly, and tables complement them, providing concrete values per every data point.

Every category contains a summary section providing an overview of the core parameters. Use the chart's detailed statistics links to dive deeper into the data and view a detailed parameter analysis.

At the bottom of each chart page is an explanation card to help you understand the data you are viewing and access the documentation if required. You can learn more about the charts and tables in the charts guide.

  • Be Be aware that the simulation for the GTI energy system uses a view factor approach with an isotropic sky model to provide fast results.

  • Simulation for PV energy system utilizes path tracing approach with anisotropic sky model for more accurate results. Because of this, you will see slight differences in the respective simulated GHI and GTI values.Incorporated horizon shading

Complementary tables provide shaded and non-shaded values for your convenience and for comparison with 3rd party software (e.g., PVsyst). The default location shading data for datasets marked withicon are calculated using Solargis far horizon.

You can edit any energy system’s horizon data in the energy system’s general settings.

Data heatmaps

Some parameters offer additional heatmaps to assist you in quickly spotting extremes and patterns. Work with them in conjunction with the charts.

PV energy system data

PV statistics, PV system losses, and PV long-term degradation categories are included for PV energy systems only, and their details are outlined in this documentation.
