About
Solargis is a comprehensive data and software platform purpose-built for the solar energy industry. It serves developers, engineers, investors, and asset managers across the entire PV power plant lifecycle—from early-stage site screening to daily operations and maintenance. The platform's flagship products include Prospect (quick solar potential estimates), Evaluate (integrated data, design, and PV simulation), Monitor (real-time PV output assessment), and Forecast (solar power output predictions up to 14 days ahead). Additional tools like Analyst, Solarmaps, and an Integrations API further expand its analytical and automation capabilities. Solargis data is delivered at 250-meter spatial resolution with 1-minute or 15-minute temporal resolution, validated against more than 1,500 ground-based measurement sites globally. The database covers historical, near-real-time, and forecast periods, making it suitable for financing, performance assessments, storage optimization studies, and regional solar energy potential analyses. Professional consultancy services include Solar Resource & Meteo Assessment, PV Energy Yield Assessment, PV Performance Assessment, Quality Control of Solar & Meteo Measurements, and Customized GIS Data delivery. A subscription to Evaluate starts at €12,000 and includes 60 early-stage projects, unlimited 15-min TMY P50 simulations, unlimited designs, and unlimited collaborators. Solargis is backed by ISO certification and over 20 years of domain expertise.
Key Features
- High-Resolution Solar Data: Provides solar and meteorological data at 250 m spatial resolution and 1-min or 15-min temporal resolution, validated at 1,500+ sites globally.
- PV Simulation & Energy Yield Assessment: The Evaluate product combines data ingestion, system design, and full PV energy simulation in a single unified workflow, including P50 TMY simulations.
- Real-Time Monitoring & Forecasting: Monitor tracks live PV output against expected performance; Forecast delivers solar power predictions up to 14 days ahead to support grid and storage operations.
- API & GIS Integrations: Automate delivery of Solargis data into third-party platforms and GIS tools, enabling custom workflows for large-scale portfolio management.
- Expert Consultancy Services: Offers bankable reports for solar resource assessment, site adaptation, performance audits, variability studies, and regional solar potential mapping.
Use Cases
- Solar developers screening and validating new PV plant sites using high-resolution irradiance data and P50 energy yield simulations.
- Financial institutions and investors obtaining bankable PV performance assessments and uncertainty estimates to support project financing and acquisitions.
- Grid operators and energy traders using 14-day solar power output forecasts to optimize dispatch and storage strategies.
- Asset managers monitoring real-time PV performance against expected output to detect faults and improve maintenance schedules.
- Research organizations and government agencies conducting regional solar energy potential studies to identify optimal locations for large-scale solar deployment.
Pros
- Industry-Leading Data Accuracy: Multiple independent studies have ranked Solargis as the most reliable solar database, with systematic global validation and transparent uncertainty quantification.
- End-to-End Lifecycle Coverage: A single platform supports prospecting, financing, construction, operations, and maintenance—eliminating the need for multiple disconnected tools.
- Flexible Collaboration: The Evaluate subscription supports unlimited collaborators and projects, making it easy for large teams and multi-stakeholder projects to work together.
Cons
- High Entry Cost: Subscriptions start at €12,000/year, making the platform inaccessible for individual researchers or very small developers without institutional budgets.
- Specialized Domain Focus: Solargis is exclusively built for solar energy applications; it is not useful outside the renewable energy and PV industry.
- Learning Curve for Advanced Features: Features like site adaptation models, uncertainty quantification, and GIS data customization require significant domain expertise to use effectively.
