Here is a close up of the photovoltic panel. It is an ARco model M65. Rated at 45 watts, 3.11 amps DC, 14.5 volts max at 25 degrees Celsius. As I mentioned earlier, the panel was purchased in 1987 and was stored unused until December 2007. This panel is not available but there are other manufacturers who make very similiar panels. 13% efficency. Silicon only absorbs a narrow range of the sun's spectrum in the near infrared. Panel technolgy hasnt changed much. Although they have panels with triple the efficency, they cost six times as much. They say there are cheap low effcency panels of 5% but i never seen them. All PV panels should have aluminum frames and wafers mounted behind glazing and encapsulated to be water proof. The industry standard warranty is 25 years.
