Hand Drive and Sun-Drive Combined

What appears to be a basic hand-driven pump can quite simply be changed to a solar driven pump with a DC motor & PV's. (60 - 90W Solar Power or 240VAC) No tools are needed; it's a one man two minute job. The handle feature means that people in developing countries can purchase the hand- pump and upgrade it later with a DC motor and solar panels. It still can be used as hand-drive at night time or in emergency. The height of the handle can be adjusted for children.

Power Supply

The Sun-Drive is one compact unit all in one. The solar panel is fitted onto a fixed array and attached on top of the Sun Drive as one sturdy unit. The solar panel is seasonally adjustable as well as for adjustment to all latitudes on the Globe. Theft protection for PV's if required. "Sentinel" (an electronic immobiliser)
