Today I visited the home of Ed & Priscilla in Hatfield PA. As part of the national solar home tour, they showcased their brick ranch home built in 1960, modernized with solar hot water, solar electric, an electric car in the garage, and day lighting.
Years ago, Ed teamed up with Alan Rushforth of Rushforth Solar and learned about the installation of large scale solar hot water systems. And about 8 years ago, Ed installed 2 solar hot water panels above their porch roof. The generated hot water is piped into a 400 gallon tank that he custom-made from his experience with Alan. This non-pressurized drain-back system needs no antifreeze because all the water drains back when the pump shuts off. The panels are US-made by Soleen.
Two years ago, Ed decided to install a rooftop solar electric system, also known as PV (photo-voltaic). The 16 panels, each rated for 345 Watts, results in a 5,520 Watt system, generating about 6,600 kWh, enough for this household. The panels are Canadian-made by Silfab Solar; the inverter is a Sunny Boy 5000.
In the garage, they’ve got an electric car, a Nissan Leaf. They need never go to the gas station with it, since the car is powered by a rechargeable battery and electric motor. The amount of electric required to keep the car charged is covered by the amount generated by the solar panels. So one could say the car is powered by the homegrown electricity. In the kitchen, they brought in more daylighting with Solatubes fitted into the roof.
Being avid gardeners, we also got to see their rain barrel, their vegetable garden, and their composting area. In addition, we were surprised to see their bee-keeping operation along the back fence, complete with fish pond providing water for the bees, and a pollinator garden supplying food for the bees. I returned home to savor some of their scrumptious honey.
