Good for battery-based systems, but these panels can be used in a variety of both grid-connected and off-grid applications. Four can be wired in series without exceeding 150Voc coldest conditions (-58 is the cutoff). Three in a series equal 48V nominal exactly (144 cells in series).
Esthetically pleasing appearance. The Day4 Electrode (a key component of the One-Sun panels) uses a fundamentally new method of contacting and interconnecting crystalline silicon PV cells - instead of solder-ribbon bonding on the front of the panel, you get an highly efficient, uniform-looking panel, able to blend with and enhance the background of any installation.
Poly-crystalline, 14% module efficiency. Tyco connectors. Made in Canada.
VOLTAGE: 170W: 23V; about 3.5% power tolerance.
