A professional technician, wearing a hard hat and safety vest, carefully lowers a RAFSUN submersible pump attached to a blue riser pipe and heavy-gauge electrical cables down into a borehole casing. He is using a manual winch tripod system on an outdoor dirt site surrounded by tools and wire spools. This detailed view of the connection and lowering phase illustrates the on-site procedures that influence exactly how long it takes to install a borehole pump effectively.

An engineer wearing a white hard hat and a yellow high-visibility safety vest is kneeling beside a drilled borehole well casing in a dry, harvested agricultural field under a clear sunny sky. Standing vertically next to the well is a sleek, multi-stage stainless steel RAFSUN submersible solar water pump. In the distant background, a large ground-mounted solar panel array is visible, providing the renewable energy source for the system. This scene illustrates the assessment and installation phase of an off-grid irrigation system, demonstrating the setup used to determine exactly how deep can a solar pump pull water from underground aquifers.
