Bill Gold is a solar pioneer who installed a `15.4 kW ground mounted solar system in 2008 at his 2,000 sq.ft. home in a rural area of New Jersey. Since then he has added two Tesla Powerwall units (for up to 29 kW storage), and three ductless heat pumps. Bill uses solar hot water for a radiant wall in his home and to heat his orchid-filled greenhouse. He has a 240 volt EV charger for his Hyundai Ioniq 5 EV.
