Solar LED Lights in a Barn Hi. I need help to plan solar-powered DC lighting in a barn to replace the AC system. The barn is too far from ac voltage and solar DC LED seems the only way to go. Reconnecting a new AC meter and new power pole is too expensive. Size: 3 compartments with no windows 20x25’ 20x15’ 10x10’ (6 LED fixtures at 1000 Lm each is enough?
