Figure 6
Two bar graphs are arranged side by side horizontally. On the left, the graph is labeled “(a) Annual energy summary one of the house”. The vertical axis is labeled “Energy in kilowatt hours”, ranging from 0 to 18000 in increments of 3000. The horizontal axis lists “High electrical load”, “Medium electrical load”, and “Low electrical load”. Three grouped vertical bars appear for each load category. The legend shows “Annual P V energy”, “Annual exported energy”, and “Annual imported energy”. Annual P V energy is high at about 15,000 kilowatt hours, followed by annual exported energy at 13,500 and annual imported energy at 5,000. On the right, the graph is labeled “(b) Annual energy summary two of the house”. The left vertical axis is labeled “Energy in kilowatt hours”, ranging from 0 to 10000 in increments of 2000. The right vertical axis is labeled “Annual P V self-consumption and self-sufficiency”, ranging from 0.0 to 1.0 in increments of 0.2. The horizontal axis lists “High electrical load”, “Medium electrical load”, and “Low electrical load”. The legend shows “Annual total electrical load”, “Annual base electrical load”, “Annual P V self-consumption”, and “Annual P V self-sufficiency”. Grouped vertical bars represent “Annual total electrical load” and “Annual base electrical load”. Two dashed line plots with circular markers represent “Annual P V self-consumption” and “Annual P V self-sufficiency”. The annual total electrical load is high at about 8800 kilowatt hours. The annual base electrical load is high at about 7800 kilowatt hours. The annual P V self-sufficiency peaks at 0.5. The annual P V self-sufficiency peaks at 0.5. Note: All numerical data values are approximated.Annual energy summary of the house under three different electrical load profiles (DHW load: small DHW load profile, output capacity of the heating element: 0 kW, threshold: 0 kW, and battery capacity: 0 kWh).
