Evaluate add-ons

The Solargis application enhances solar resource assessment capabilities through specialized add-ons, available exclusively for Full evaluation projects. These add-ons come in the form of additional datasets for comprehensive project analysis.

You can access and manage the add-ons in the main menu under Data & services in the Solargis data tab, described in Data & services page. For expert services rather than datasets, see Evaluate add-on services.

Available add-ons

The Data & services section offers access to the following datasets to upgrade your project data source:

• Uncertainty data

• TMY Pxx data

• High temporal resolution data (1-minute)

• Site adaptation of the Solargis Model

Important: Some of the datasets may take time to activate as they are manually processed by our team of experts.

Uncertainty data

Solar irradiance uncertainty estimates enable robust validation of resource assessment and performance forecasting. This includes:

• Detailed irradiance variability metrics

• Enhanced accuracy in energy yield predictions

• Improved risk assessment for project financing

Once the add-on has been activated, the data will be available in the Uncertainty category under the Analysis section. Clicking the charts icon will redirect you to the page.

Important: If you have multiple data sources in your projects and want to see uncertainty for each of them, you will need to request uncertainty separately for each of them. The activation is not automatic and always applies to the relevant data source only.

Note: This data is included in Full evaluation at no additional cost.

TMY Pxx data

The TMY datasets with different probability of exceedance levels provide varying confidence intervals for energy yield predictions:

• TMY P99: Extremely conservative estimate suitable for worst-case scenario planning.

• TMY P95: Very conservative estimate for risk-averse financial modeling.

• TMY P90: Conservative estimate commonly used for bank financing, expected to be exceeded 90% of the time.

• TMY P75: Moderately conservative estimate for balanced risk assessment.

• TMY P10: Optimistic scenario useful for analyzing maximum potential performance.

Clicking the download icon of the respective Pxx data (activated only) will redirect you to the Download section, where you can initiate the data download.

Note: This data is included in Full evaluation at no additional cost.

High temporal resolution data

1-minute resolution dataset provides critical insights for advanced system design and operation:

• More accurate prediction of power output fluctuations

• Better assessment of inverter clipping losses

• Improved grid integration planning

• Enhanced analysis of cloud edge effects

• More precise sizing of energy storage systems

This high-resolution dataset is particularly valuable for utility-scale projects where accurate performance modeling and grid compliance are essential. It is generated automatically in the background and may take approximately 15 minutes depending on the location.

Note: This data is available for Full evaluation projects only and is not included in the project activation price. You can purchase it at an additional cost.

Site adaptation of Solargis Model

This lets you request a data source adapted to site-specific conditions for better accuracy. Using your on-site ground measurements (minimum 12 months), we recalibrate our solar and meteorological models to your specific project location, reducing data bias and uncertainty for more reliable energy assessments.

What's included:

• Full quality control and metadata harmonization of your measurements

• Site-adapted time series and TMY P50 data integrated directly into your Evaluate project

• Ability to run energy simulations, generate reports, export outputs, and derive additional TMY Pxx percentiles, all based on higher-confidence, location-tuned data

Note: This service is quoted individually based on project complexity, measurement quality, and completeness of provided documentation. Contact your account manager for a personalized quote and a list of required inputs.

To request site adaptation:

1. Click the "Request now" button.

2. Read the on-screen disclaimer and submit the request.

Activating add-on data

You can activate all available datasets on the Data & services page:

1. Click the "Activate" link next to the add-on you want to activate.

2. Active add-ons are marked as "Active".

Important: Please be aware that additional add-on data delivery might take up to 24 hrs to show on your account.

If you are activating a paid dataset, for example high temporal resolution data (1-minute data), the cost will be displayed in the confirmation prompt. Confirm that you wish to spend SGU for the add-on activation. Data will be delivered to your project automatically after processing.

Note: We will send a confirmation notification to your email once you request activation of any dataset.
