Yesterday Electric Energy Used (53.7 kWh) from Sense and Daily Solar Electric Energy Produced (52.6 kWh) from SolSystems and Locus Energy. More sun and cooler. The Geothermal HVAC was off. Server backup and new hydroponic garden online. Overall a net deficit of 1.1 kWh.

Daily Electric Energy Used (66.0 kWh) from Sense and Daily Solar Electric Energy Produced (51.3 kWh) from SolSystems and Locus Energy. Warmer out so the Geothermal HVAC was back on (5.2 kWh), Using more electricity while running server backups, laundry (3.7 kWh) and new hydroponic garden. Overall a net deficit of 14.7 kWh.

Backyard Summertime Nature in New Jersey.

Daily walkabout with a Nikon D810a camera and 70-300 mm VR lens. Mexican Sunflower, Butterflies (Painted Lady, Eastern Tiger Swallowtail, and Spicebush Swallowtail), and Hummingbird Clearwing (white legs) Moth on a Lemon Mint Flower. Note, I previously thought that these were Bee Balm Flowers.

Daily Electric Energy Used (54.3 kWh) from Sense and Daily Solar Electric Energy Produced (64.4 kWh) from SolSystems and Locus Energy. One laundry load (3.0 kWh) and two dishwasher loads (~5 kWh). Still a net surplus of 10.1 kWh.

Monthly electric energy used (1664 kWh) and solar electric energy produced (1764 kWh) for a net surplus of 100 kWh.

Backyard Summertime Nature in New Jersey.

Daily Walkabout, today with a Nikon Df camera and 70-300 mm VR lens. The thing I like about this camera is that it light for a DSLR, and has the same full-frame 35 mm sensor as the Nikon D4 camera. I have to admit that the camera failed on me once while in Antarctica when the shutter failed. The 70-300 mm lens is also relatively light. This post is about the flowers. Sunflowers, Zinnia, Black-eyed Susan, Gloriosa Daisy. The red flower I couldn’t identify yesterday appears to be a Mexican Sunflower.

Daily Electric Energy Used (66.1 kWh) from Sense and Daily Solar Electric Energy Produced (65.5 kWh) from SolSystems and Locus Energy. Fewer clouds and more sun. The WaterFurnace geothermal HVAC had to work harder (25.6 kWh) because the temperature outside went above 90°F. Daily net deficit 0.6 kWh.

One note — the WaterFurnace Symphony software indicated the system used 16 kWh, however the Sense Energy monitor indicated that the geothermal heat pump used 25.6 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.
