Nenhum tipo de motor é superior ao outro em todas as aplicações; dependendo das necessidades de energia, localização e custo.

• DC pumpsare pumped directly off the panels, thus no inverter losses. They start at low sunlight, suit small livestock troughs and household tanks, and handle heads up to about 150 m in the 0.3–2 kW range. Fewer electronic parts mean lighter weight and easier field service, yet cable runs must stay short to avoid voltage drop.

• AC pumps use a solar inverter. This adds cost, but opens the door to larger motors—up toSAMKINGPump’s 20 kW—longer cable runs and simple backup from the grid or a generator at night. Standard three-phase motors are widely available, which helps when you need quick replacement.

• Hybrid systems combine both modes. The built-in controller switches between PV and grid as needed, giving steady water even on cloudy days.

Combine o tipo de motor com seu fluxo diário, profundidade do poço e acesso à energia elétrica e dimensione o conjunto para pelo menos 1,3 × potência do motor.
