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. Yesterday, I said it had been some time since I had seen a hummingbird moth. Well, today the Hummingbird Clearwing Moth (Hemaris thysbe) returned. And I took a lot of pictures. Feeding on Bee Balm flowers, Cosmos flowers, and Zinnia flowers.

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.

Backyard Summertime Nature in New Jersey.

Daily Walkabout, today with a Leica CL camera and 55-135 mm lens. The thing I like about this camera is that it is lightweight and potentially a great travel camera. Most of the images were taken at 135 mm (field of view equivalent to 200 mm on a 35 mm sensor camera). It doesn’t have all of the bells and whistles of some of my other cameras. I do need to take it out periodically just to maintain the brain and muscle memory to use it effectively. This is the longest zoom lens for the Leica TL and CL cameras. The Goldfinches are all over the smaller Sunflowers. They want the seeds fresh. A lot of butterflies were out working the wildflowers (Painted Lady, Sulphur, a pair of frisky Spicebush Swallowtails, and a pair of Monarch’s mating). The Monarch’s  were flying around paired together and I finally caught them resting in a pine tree from a distance.  I haven’t seen a hummingbird moth recently. Then some flowers (Backlit Red Sunflower, Bee Balm, a Red flower I haven’t identified yet, Partridge Pea with Pea Pods, a Zinnia, and a pair of small Yellow Sunflowers. Finally, the poisonous Poke Weed berries.

Daily Electric Energy Used (61.1 kWh) from Sense and Daily Solar Electric Energy Produced (51.2 kWh) from SolSystems and Locus Energy. More clouds and bit less Sun. The WaterFurnace geothermal HVAC had to work harder (25.7 kWh) because the temperature outside went above 90°F. Daily net deficit 9.9 kWh. Weekly totals  412 kWh used, 350 kWh produced. So far still ahead for the month of August, but will need some more sunny days

One note — the WaterFurnace Symphony software indicated the system used 14 kWh, however the Sense Energy monitor indicated that the geothermal heat pump used 25.7 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.

Backyard Summertime Nature in New Jersey.

Daily Walkabout: I went out with a Fuji X-T3 camera and 200 mm f/2 OIS lens. Butterflies (Spicebush Swallowtail, Silver-spotted Skipper, Monarch, Painted Lady, Common Buckeye, and Tiger Swallowtail). Bumble Bees on a variety of Sunflowers. Leaf-legged Bug on a Thistle, and an ant on a Bee Balm.

Daily Electric Energy Used (60.3 kWh) from Sense and Daily Solar Electric Energy Produced (25.5 kWh) from SolSystems and Locus Energy. A load of Laundry (3.7 kWh) and two loads in the dishwasher contributed to the increased energy used. The sky was cloudy most of the day (but no measurable rain) impacted the solar production. Daily net deficit 34.8 kWh.
