Harness the power of the sun with our Grundfos pre-designed solar water pumping kits—engineered for simple installation and reliable performance. At The Solar Store, we currently offer 7 pre‑designed SQFlex kits that eliminate the guesswork of piecing together individual components. 

Whether you’re pumping water for livestock, agriculture, ranches, or off-grid cabins, these systems are built to deliver dependable water access backed by Grundfos’ reputation for durability.

Most kits include 2–6 monocrystalline solar panels with weatherproof MC4 connectors and a top-of-pole solar mount, designed to perform in varied site conditions. The system size adapts to your required flow rate and vertical lift, ensuring efficient operation even in shaded or long-cable environments. 

For greater flexibility, consider exploring Submersible Solar Well Pumps or adding Grundfos SQFlex Pump Components for customized configurations.
