Panasonic 370W EverVolt Black Series

Panasonic's 120-cell Evervolt module is suitable for both commercial and home installations, with an output of 370W. It's part of the Black Series - note the amazing design of this model. It features an excellent efficiency of 21.2%. With an annual power loss of 0.25%, you'll still have at least 92% of the rated power available in year 25. Half-cut cells combined with HIT technology reduce power losses and keep power high even at high temperatures. The model comes with a 25-year warranty on performance, product, parts and labor.


Here is a 120-cell panel with 360-380 W output, suitable for both home and commercial installations of medium size. The efficiency reaches up to 21.7%. Heterojunction technology makes the panel a good choice for hot areas. The degradation rate is amazingly low - only 0.25% power loss per year. The manufacturer claims that with Alpha you get up to 20% more energy overall than with conventional panels. The frame is reinforced so it can withstand 146 lbs/sq ft of pressure. That's equivalent to a wind speed of 250 mph: basically, the module is ready for any kind of tornado or hurricane that comes its way.
