Solar Array Configuration
Calculate series/parallel configurations for your solar panels.
Series vs Parallel
Series Connection
Voltage adds, current stays same. Use to meet inverter minimum voltage requirements. Reduces current and wire size needs.
Parallel Connection
Current adds, voltage stays same. Use to increase power while staying within voltage limits. Requires larger wires for higher current.
Temperature Considerations
Cold weather: Voc increases up to 25%. Ensure string Voc stays below inverter max.
Hot weather: Vmp decreases. Ensure string Vmp stays above inverter minimum.
