Find the optimal sites for solar energy projects
Xweather gives you instant access to over 25 years of historical solar irradiance and weather time series data for solar resource assessments, output forecasts, and risk analysis. Comprehensive data helps you choose the best sites, designs, and technologies for your solar projects to maximize energy output and minimize risk.
Cut your solar resource uncertainty in half
Accurate solar resource data is critical for site assessment. Xweather uses advanced statistical techniques to correct the bias in historical solar irradiance data derived from satellites. This process reduces the uncertainty by more than 50%, allowing you to predict a project's feasibility and energy yield with more confidence.
High-quality wind data for resource assessment
Unlock the potential of your wind energy projects with high-quality historical wind resource data for site selection, resource assessment, and climate impact studies. Xweather supports every stage of wind energy development helping wind farm developers and operators make informed decisions to enhance project viability and success.
Set your energy generation budget with confidence
How much of last month’s departure from expected production was caused by the weather? What should you expect next month or quarter? Xweather provides an independent monthly assessment of the weather's impact on your wind and solar project portfolio so you can set annual energy generation budgets, produce monthly operating reports, and determine the causes of under- or over-performance.
