JA Solar 405W Solar Panel 108 Cell JAM54S31-405MR
Another advantage is the half-cut cell technology. JAM54S31-405MR has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. As a result, the panel achieves an impressive efficiency of 20.7%. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal. JA Solar provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.
