Being certain about solar radiation uncertainty

The process of estimating solar radiation data uncertainty can be sometimes unclear. We've tried to summarise in 4 simple steps how model validation statistics can be used for determining uncertainty of model estimates for P75, P90, and other Pxx estimates. Read article

How Solargis is improving accuracy of solar power forecasts

Just as there are horses for courses, different forecasting techniques are more suitable depending on the intended forecast lead time. Ground-based and satellite-based methods offer best forecast skill for forecast lead time of few hours ahead. Beyond that NWP models offer best forecast skill. A combination of models provides better forecast than any individual forecast model. Read article

Solargis approach on site-adaptation of satellite-based DNI and GHI time series

Accurate solar resource data is needed for planning, engineering and financing of a solar energy project. Read article

Why to use satellite-based solar resource data in PV performance assessment

It is widely accepted that high-standard pyranometers operated under rigorously controlled conditions are to be used for bankable performance assessment of photovoltaic (PV) power systems. Asset managers, O&M providers, and owners of PV portfolios are increasingly relying on satellite-derived solar resource data. Read article

WEBINAR: Solar resources data applications for utility planning and operations

On Monday 23 Feb 2015 at 16:00 UTC, Marcel Suri (Solargis) and Tom Hoff (Clean Power Research) present the use of weather satellite data to estimate the solar energy resource and availability and accuracy of derived data products. Read article
