FAQ
Questions and Answers
Everything you need to knoe about Solstice AI™ and what we do
What are Solstice AI's products?
We are currently offering two main products.
Solstice SkyScan™ scans extended regions (such as entire states) and finds the exact locations, sizes, and orientations of all solar PV systems. This includes residential (rooftop), commercial/industrial, and large-scale (solar farms).
Solstice SkyFlow™forecasts the formation and movements of clouds, the main driver of solar variability, enabling highly accurate solar generation forecasts.
We can provide solar generation forecasts for individual sites (including solar farms), or for entire regions.
How does the solar identification work?
We train artificial intelligence models on millions of images of solar PV systems. They can differentiate between solar PV and solar hot water, and they can determine the orientations of solar PV systems.
If the underlying imagery is good enough, our models have an accuracy of 97%.
As a result, we can scan large regions and quickly identify exactly where all the solar PV systems are, and what their generating capacities are.
How does the solar forecasting work?
Using a combination of artificial intelligence and cloud motion vectors, we examine real-time satellite images and forecast how clouds will form and move in the next 2-3 hours. Each artificial intelligence model is trained specifically on the region of interest. This is important, since local factors such as coastlines, hills, or mountains can affect cloud formation. The resulting solar generation forecasts are more accurate than if global irradiation models are used.
Where does the data come from? Can you do this anywhere in the world?
For solar identification, we partner with several third parties to obtain overhead imagery. For most populated regions there is high-quality imagery available that is updated regularly. Some countries and regions have their own local data providers, but this generally has to be checked on a case-by-case basis. If data with sufficient resolution is available, we can procure it and analyse it.
For solar forecasting, satellite imagery is available across the globe from several major satellite data providers.
Who uses your products?
Solar energy is the world’s fastest growing form of electricity generation, and all major markets need to prepare for a future in which much of our energy will come from solar.
Energy market operators need to forecast solar generation to ensure that electricity supply matches demand at all times.
Energy network operators need to understand where all the solar is (and where it will be) – both for planning purposes and to manage short-term voltage fluctuations in the grid.
Energy generators (including solar farms) and retailers who trade in energy markets need to know in advance if there will be solar energy shortfall or oversupply, so that they can adjust their bidding accordingly.
Entities who manage fleets of solar + storage assets, such as virtual power plants, need solar forecasts to optimally charge and discharge batteries.
What kind of consulting do you do?
We have an extensive background in providing state-of-the-art solutions to the energy sector.
Every region is different and may have different needs and incentives when it comes to analysing and understanding solar generation or other large sources of data (such as smart meter data).
Our PhD-qualified team can assist with applying state-of-the-art machine learning and artificial intelligence methods to industry problems to help our clients reduce their costs and increase revenue.
