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 and expert services for comprehensive project analysis. Add-ons are segregated into two categories: Add-on data and Add-on services.

You can request them using the three-dot menu while on the Full evaluation project page:

1. Open the projects menu.

2. Select “Request add-on data” if you want to request TMY Pxx datasets, GHI/DNI uncertainty, or high temporal resolution data (1-minute resolution).

3. Select “Request consultancy services” to access add-on services, e.g., Bankable site adaptation of Solargis Time Series or Consultancy support for complex photovoltaic projects.

Proceed in the next dialog, choose the add-on/service, and submit the request.

Add-on data

Data add-ons enhance solar resource assessment by providing specialized datasets that enable more sophisticated analysis and improved decision-making for solar projects.

TMY data by exceedance probability (Pxx)

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.

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

GHI/DNI uncertainty

Solar irradiance uncertainty data enables 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

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

High temporal resolution (1-minute) data

One-minute resolution data 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 data is particularly valuable for utility-scale projects where accurate performance modeling and grid compliance are essential.

This data is not included in the Full evaluation activation price and is available to you at an additional cost.

Add-on services

Evaluate application add-on services enhance project assessment capabilities by introducing specialized services and expanded datasets. They were created to provide deeper insights through higher resolution data processing, supplementary albedo measurements, or customized consulting services. The following add-ons are available:

• Bankable site adaptation of Solargis Time Series and TMY model data.

• Ground surface albedo Time Series for higher accuracy PV simulation input.

• Bankable site adaptation of ground surface albedo Time Series.

• Consultancy support for complex photovoltaic projects.

Bankable site adaptation of Solargis Time Series and TMY model data

The highest solar and meteorological model data accuracy is achieved by adapting the models to ground-based solar and meteorological measurements from your project site. Solargis experts will conduct a full quality assessment of your measurements and pre-process them for adapting solar and meteorological models to represent local geographical conditions as realistically as possible. As part of the service, our experts will review all input data for solar and meteorological models (satellite, atmospheric, meteorological, and terrain) and validate the model outputs using quality-controlled on-site measurements.

Added value: You will receive Solargis Time Series and TMY data with high accuracy and low uncertainty, along with expert reports on quality assessment results and site-specific model adaptation.

This product is designed for ultimate technical design optimization and bankable financial transactions. This service requires the availability of on-site ground measurements.

Ground surface albedo Time Series for higher accuracy PV simulation input

This service delivers daily time-resolution ground surface albedo (ALB) data Time Series, derived from models that combine MODIS-satellite data products with Solargis solar radiation Time Series. The ALB data product validation relies on data from locations with similar geographic conditions.

Added value: Together with the site-specific Time Series data, you will receive an expert report containing accurate long-term averaged values for bifacial PV simulation. The report identifies ALB geographic and temporal variability in the project area, including analysis of surface variability, seasonality, and short-term variations caused by snow, rain, and other geographical and human-induced effects.

Higher accuracy bifacial PV simulation results reduce performance risks. This service does not require ground measurements.

Bankable site adaptation of ground surface albedo Time Series

This service delivers high-accuracy daily Time Series of ground surface albedo (ALB) data. The primary ALB data is derived from models combining MODIS-satellite data products with Solargis solar radiation Time Series. Data accuracy is enhanced through site-specific adaptation using on-site solar radiation and albedo measurements.

Added value: You will receive site-specific Time Series data delivered by an expert report containing accurate long-term average values for bifacial PV simulation. The report identifies ALB geographic and temporal variability in the project area and recommends the most suitable ALB data solution for bifacial PV simulation. It includes analysis of surface geographical variability, seasonality, and short-term (daily) variations caused by snow, rain, and other geographical and human-induced effects.

High-accuracy ground surface albedo data are critical for bankable bifacial PV simulation results and reduced risk of PV project underperformance. This service requires on-site ground measurements.

Consultancy support for complex photovoltaic projects

Solargis Evaluate utilizes proprietary PV energy design and PV simulation software. The algorithms for realistic 3D design and ray-tracing PV simulation are enhanced by a verified catalog of PV Components. All simulations are based on Solargis high-resolution data.

We support specific needs in complex project designs and PV performance optimization, aligned with your business model. Our capabilities include novel hybrid (PV-wind-storage) architecture integration and incorporation of on-site drone and land survey data. Using 1-minute Time Series data, we provide high-frequency PV performance analysis, offering insights into PV design details and addressing power smoothing requirements of grid operators.

Added value: You receive customized PV simulation outputs and expert reports addressing your specific requirements. Our specialized data and software capabilities provide developers and investors with independent project performance evaluation, including comprehensive uncertainty and risk assessment.

This service may require internal tools not currently available in the public version of Solargis Evaluate.
