This particular model is a single unit of 144Cells, 24-48V 545Wp Half-Cut Monocrystalline Solar Panel that is popularly used for recharging 24V batteries used in inverters, for running 24V appliances such as LED TVs, battery chargers etc. and for ON & OFF GRID Solar Installations.
This module produces energy even if part of the module is shaded unlike conventional solar modules wherein if they're partially shaded, minimum one string will completely stop product power which accounts to 1/3rd reduction in power generation. This module is split into two parts of 72 half cut cells which generate power on standalone basis but combines again before current exists the module thus resulting in higher overall energy yield.
The product comes with 1M wire, Three Junction Boxes and Universal Connector.
