PV Disaggregation
What is PV disaggregation?
This feature is designed to estimate how much energy a household has produced and consumed based solely on data from their utility smart meter. It allows users to monitor energy production over time, calculate self-consumption, and gain insights into energy consumption. Remarkably, this is achieved without the need for additional hardware integration. The feature provides valuable insights such as energy forecasting, comparisons with similar homes, and a detailed breakdown of energy usage.
How does the algorithm work?
The algorithm begins by estimating the maximum solar energy curve on a clear sky day. Then, it employs advanced machine learning techniques that take into account the import/export profile and weather data. Using this information, the algorithm accurately calculates both the actual consumption and production of energy at the property.
What data is required for this feature?
To utilize this feature, you'll need data on both imported and exported energy usage for a specific location, along with its approximate geographic coordinates.
How is this feature configured for use?
This feature requires configuration to be enabled. It is designed to work with the input of a "perfect" day, such as an hour of uninterrupted sunlight with no clouds and export. This day is used as the basis for determining the system size, which is then adjusted for always-on consumption.
How accurate is this feature?
Recent case studies have shown that this feature boasts an impressive accuracy rate, ranging from 90% to 92%. This means that it provides highly reliable estimates of household energy production and consumption.
