What are Solargis Solarmaps?

Solargis Solarmaps offer PV managers interactive maps for assessing last month’s weather impact on PV performance, enhancing accountability, and visual reporting.

Look into last month’s Global horizontal irradiation, air temperature, precipitation and wind speed, the key external factors affecting PV performance.

  • Monthly weather variation compared to LTAs
  • Harmonized last month’s summaries of key PV performance indicators
  • Weather variability in geographical context
  • Effective communication with stakeholders
  • Independent 3rd party assessment of PV performance
Uncover the last month’s data for your selected sites

Uncover the last month’s data for your selected sites

Assess harmonized monthly summaries and compare actual values with your targets or on-site measurements. To unlock precise site-specific last month’s data, simply click on a map and locate your projects.

Values for the previous month will enable you to attribute unexpected performance to environmental factors and support the assessment of financial impacts.

Example: Monthly average temperature (°C) for the selected sites in January 2025

Side-by-side analysis

Side-by-side analysis

The split view feature allows you to combine multiple parameters and aggregations seamlessly, enabling a more in-depth analysis of the correlation between your selected variables.

By viewing these insights side by side, you can assess their impact on monthly PV performance in one screen. This flexibility let’s you identify trends, draw meaningful conclusions, and make confident data-driven decisions. 

Example: Monthly total of GHI (on the left) vs. monthly total of precipitation (on the right) in January 2025

Recognize cyclic trends and extreme weather through graphs

Recognize cyclic trends and extreme weather through graphs

The graphical representation makes it easy to analyze seasonal trends and the impact of weather fluctuations over time, helping you grasp the full picture of performance and environmental factors.

Additionally, the graph visualizes full historical data for any site, including monthly and yearly time series, as well as variability (shown as “difference”). 

Example: The graph illustrates Time Series of monthly averages of wind speed for the full history of selected sites

Independent 3rd party assessment of PV performance

Independent 3rd party assessment of PV performance

The world map offers a comprehensive geographical context of solar and meteorological events, allowing you to quickly identify if external environmental factors contributed to unexpected underproduction. 

This helps determine whether the PV performance aligns with weather conditions and provides a clear understanding of when further investigation may be necessary.

Example: GHI monthly difference in January 2025 against long-term monthly average (%)

Search locations within a custom value range

When a map layer is selected, it is possible to define the range of monthly or annual values that you want to see on a map.

The map will visually provide you with the areas that fall into your desired range and grey out the rest. 

Example 1: Geographical areas where GHI totals in January 2025 were higher than 150 [kWh/m²]

Example 2: Geographical areas where GHI totals in 2024 were higher than 2000 [kWh/m²]
