What is the impact of photovoltaic battery capacity on building energy autonomy?
What is this graphic showing? Describe the different parts of the graphic and how it communicates the data.
The battery levels and export electricity is simulated for a photovoltaic panel array on a typical building over a typical week. The battery capacity is varied over a range of [100,1000]kWh with a 100kWh step. With a higher battery capacity, the battery level over the week increases, while the total export electricity decreases; the total load match index (PV yield to building energy load ratio) decreases, while the percentage of days where daily load is matched increases.
