Portable solar irrigation pumps are devices specifically designed for mobile and flexible irrigation. They typically combine solar power with a lightweight structure, making them suitable for farmland, vegetable gardens, orchards, or emergency water supply scenarios without grid coverage. Their construction mainly revolves around four core modules: energy harvesting, energy conversion, power drive, and portability integration.
They are usually composed of multiple foldable or modular solar panels, using monocrystalline or polycrystalline silicon materials, which are lightweight and weather-resistant.
Some designs employ a foldable frame structure, increasing the light-receiving area when unfolded and reducing the volume by more than 60% when folded, making them easy to carry and store.
The output power is generally between 60W and 300W, sufficient to drive a small water pump. Some models support direct drive or charging of the built-in battery.
Photovoltaic water pumping inverter/controller: The core component, responsible for converting the DC power generated by the solar panels into AC power required by the water pump (or directly driving the DC pump), and achieving maximum power point tracking (MPPT) to ensure maximum energy utilization under different lighting conditions, with an efficiency of up to 99%.
Intelligent protection functions: Built-in overvoltage, undervoltage, overcurrent, and dry-pump protection mechanisms; automatic start/stop capability; adaptable to cloudy days or low-light environments.
