Make confident decisions from the start

Make confident decisions from the start

Access to long-term, high-resolution solar and meteorological data is crucial in early project development.
It supports accurate site assessment and selection of high-potential locations.

Historical solar and climate data helps show project interactions with local environmental conditions, aiding in regulatory approvals and ensuring compliance with sustainability standards.

Reliable energy yield predictions

Reliable energy yield predictions

Accurate energy yield estimates are essential for project financing and feasibility studies. The Solargis Time Series API offers precise historical solar radiation data, enabling you to generate reliable long-term performance predictions. 

Historical data from the Solargis Time Series API can be fed directly into financial models or other software tools for accurate economic projections which are required by investors and banks to assess the viability of solar projects.

Design PV systems that withstand extreme conditions

Design PV systems that withstand extreme conditions

With access to decades of historical climate data, you can model extreme weather events, variability in solar radiation, and other meteorological factors, ensuring that projects can withstand long-term environmental fluctuations.

The availability of sub-hourly historical Time Series data helps you optimize the configuration of PV systems. By using detailed data on weather patterns, you can adjust the tilt, orientation, and layout of PV panels to maximize energy capture, leading to more efficient PV system designs.
