# Read the solar charge controller's instructions before installing your kit.
* Remember to make sure that the black (negative) wire is fitted into the port marked negative and the red (positive) wire is fitted into the port marked positive.
^ For extensions of up to 8M use 4mm2 rip cord. For extensions of 9 to 20M use 6mm2 conductor cable.

The thin-film solar technology that we offer converts sunlight directly into DC electricity by means of triple-junction, amorphous silicon, thin-film cells. The semi-conductor junctions are stacked on top of each other and form three different sub-cells. The bottom sub-cell absorbs the red light, the middle sub-cell absorbs the yellow/green light and the top absorbs the blue light. Several of these triple-junction cells are connected together to provide the specified output voltage.
During the manufacturing process solar material is deposited onto a tough, durable stainless steel sheet while it is fed through a series of vacuum chambers. The solar cells are laminated in flexible, weather-resistant polymers that are able to withstand harsh climates.
