How big a cable should I choose for outdoor photovoltaic panels

Why 10-American-Wire-Gauge (AWG) is selected as the standard for external connection of solar arrays due to the following:Oversized for safety & voltage dropLow resistance for solar current of 30 Amps per single panelThe voltage drop over distance is lowCable is flexible [pdf]

Why do photovoltaics use aluminum alloy brackets

When the steel bracket is connected to the aluminum photovoltaic panel frame, the aluminum photovoltaic panel frame is prone to galvanic corrosion, while the aluminum bracket avoids this phenomenon. [pdf]
