Shade Resistance
Non position dependent
– Thin film module electrical construct reduces impact of partial shading
– Thin film modules high voltage enables parallel interconnected short strings
• Lower line losses
• Minimised impact from shading
• Negates need for micro-inverters

Thermal Control
• Reducing heat gain/loss in a buildings with g-value @ 0.24
and Double Glazed units u-value @ 0.95.
