Each forecast component is calculated independently, using independent input data, which creates redundancy and increases overall reliability.
The PFS forecast combines each of these methods, with optimal weights as a function of the forecast horizon, so that the combined forecast has the best performance over all time scales.
The PFS uses proprietary algorithms and infrared satellite images to detect clouds at night. This enables accurate forecasts in the hours before dawn which assists solar farm operational decisions. For example: should a battery at a solar farm discharge 2 hours before sunrise to take advantage of a price spike, and will there be clear skies in the morning to recharge?
Proa skycams provide the best forecasts for short time scales — up to 15 minutes ahead. Proa is proud to partner with Sieltec Canarias, a leading manufacturer and supplier of skycams and weather sensors, and has developed new techniques to track and predict cloud motion using skycam images.
Proa can provide accurate forecasts for any location in Australia using our state-of-the-art satellite forecasts. These satellite forecasts do not require any equipment installed at a site and so are extremely economical. They are almost as good as skycam forecasts for up to 15 minutes ahead, and the best forecast method up to 6 hours ahead. Proa can in fact forecast at any location between India and Hawai’i using the Himawari-8 satellite images, and other locations will be available soon.
Proa incorporates live data from a solar farm or system to increase forecast accuracy, especially . For solar farms, SCADA data can be transmitted securely via MODBUS VPN, https POST API, or, for customers of our partner HARD software, using the pre-built SCADA Infolite interface.
Proa includes numerical forecasts for the best weather agencies in the world, including Australia’s own Bureau of Meteorology (BOM), the European Centre for Medium-Range Weather Forecasts (ECMWF) and the US National Oceanic and Atmospheric Administration (NOAA)
