Backyard Summertime Nature in New Jersey.
Daily Walkabout, today with a Nikon N1V3 camera and 70-300 mm VR lens. My favorite lightweight kit, with plenty of reach. The Snowberry Clearwing Moths (with the black legs) are back. They also like the Bee Balm flowers. Monarch Butterfly feeding on a Marigold flower, and Eastern Tiger Swallowtail Butterfly feeding on a Zinnia flower. There has been rain all around us, but not here. The pond level is down, and the frogs are skittish. A small sparrow (LBJ) and a fawn trying to hide behind some grass.
Daily Electric Energy Used (59.7 kWh) from Sense and Daily Solar Electric Energy Produced (61.3 kWh) from SolSystems and Locus Energy. The WaterFurnace geothermal HVAC had to work hard (25 kWh) because the temperature outside went above 90°F. A bit more sun so a net surplus of 0.6 kWh. Cooler weather expected tomorrow!
One note — the WaterFurnace Symphony software indicated the system used 15 kWh, however the Sense Energy monitor indicated that the geothermal heat pump used 25 kWh. I tend to believe the Sense numbers since they more closely the energy being recorded at the external power company (PSE&G) meters. I’ve asked the WaterFurnace folks in the past about the discrepancy, but they didn’t have a good answer. The Sense folks told me they thought that the WaterFurnace/Symphony system was only measuring one phase of the energy even though the system is powered by the 220V circut (using two phases). I wish an electrical engineer that understands this better would correct me here.
