Solar-TK is a data-driven toolkit for solar performance modeling and forecasting that is simple, extensible,and publicly accessible. Solar-TK’s simple approach models and forecasts a site’s solar output given only its location and a small amount of historical generation data. Solar- TK’s extensible design includes a small collection of independent modules that connect together to implement basic modeling and forecasting, while also enabling users to implement new energy analytics.
A key goal of Solar-TK is to be simple to use by researchers that require realistic and accurate solar performance models and forecasts, but are not experts in these areas.
We quote our Solar-TK paper explaining the need for a toolkit:
Much of the research work on solar performance modeling and forecasting is not accessible to researchers outside the area, either because it has not been implemented and released as open source, is too complex and time-consuming to re-implement, or requires access to proprietary data.
To address the problem, we present Solar-TK, an open data-driven toolkit for solar performance modeling and forecasting that is simple, extensible, and publicly accessible. A key goal of Solar-TK is to be simple to use by researchers that require realistic and accurate solar performance models and forecasts, but are not experts in these areas. Solar-TK includes:
- a dataset of solar power generation and energy consumption across hudreds of homes
- a module to estimate the physical specifications of a solar site, i.e. capacity, tilt, orientation
- a module to estimate the maximum generation potential of a solar site
- a module to estimate the weather-adjusted generation for a solar site
- a module to adjust the estimated output for shading by nearby buildings and trees (will be added in future)
- a module providing metrics used in solar modeling and forecasting (will be added in future)
