FAQ's About Samking

Size your solar pumping system by calculating daily water demand, matching pump power (HP/kW) to well depth and required flow rate, and adding solar panel wattage to cover total energy needs plus a safety margin for cloudy conditions. Always optimize for maximum Vmp and suitable panel configurations (series/parallel).
