3.1 General

LORENTZ solar submersible and surface pump systems
are designed to efficiently deliver high volumes of water
running exclusively on solar power. They are typically used
in irrigation projects and for wide area drinking water
applications where they reliably meet the most demanding
requirements, economically, without pollution and without a
grid connection or diesel generator.
A typical solar pumping system is composed of a PV gen-
erator array, a pump and a solar pump controller. Based on
the design philosophy that it is more efficient to store water
rather than electricity, there is no energy storing device such
as a storage battery in a typical solar pumping system.
The PV generator, an aggregation of PV modules connected
in series and in parallel, absorbs solar irradiation and con-
verts it into electrical energy, providing power for the whole
system. The pump controller controls and adjusts the system
operation and adjusts the output frequency in real-time
according to the variation of sunlight intensity to realize the
maximum power point tracking (MPPT).
Each LORENTZ pump system consists of a pump end,
pump motor and a controller. This modular concept keeps
all electronics above ground even for submersible pumps,
simplifying servicing and lowering cost of ownership.
