Solar Pumps


Solar water pumps are for many, a more reasonable source of energy for pumping wells than windmills. While both windmills and solar powered pumps are useful in remote areas that are not tied to the grid, solar power is generally both less expensive than its wind-powered counterpart, as well as easier to install.

For locations beyond the reach of power lines and with little wind, solar pumps offer a clean and simple alternative to fuel-burning generators. Using the principle of ‘thermo dynamics’ they require no batteries, no high-voltage electricity, no engine consuming gasoline or diesel fuel – only harmless, low-voltage, solar-generated electricity, eternally available and pollution free and requiring very little maintenance.


The most economical DC water pumps are surface (non-submersible) pumps. They can reduce pumping energy consumption by half or more, compared to conventional AC pumps. Surface pumps can pull the water up to 10 meters (suction capacity) and lift or push up to 100 meters. Solar pumps have a wide range of applications and can provide as little as 2 liters per minute and up to 250 liters per minute. Surface pumps must be protected from weather.

Submersible Solar Pumps

Submersible water pumps are used in well pumping up to  10 meters, pressurized and non-pressurized irrigation, home water systems and livestock watering. There are no limits to how large solar-powered pumping systems can be built. But, they tend to be most competitive in small installations where combustion engines are least economical.


A solar cell, or photovoltaic cell, is a device that converts light energy into electrical energy. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the light source is unspecified. The field of research related to solar cells is known as photovoltaics.

Solar electric panels contain many photovoltaic cells, electrically connected and packaged behind glass for mechanical protection and electrical insulation. The modules are usually connected together in an array, and with other components such as a mounting frame and an electrical inverter (for on grid), or a charge controller and batteries (for off grid).

In addition to solar panels, a photovoltaic (PV) system requires a mounting structure to tilt panels toward the sun, an inverter to convert panel-generated direct current (DC) into appliance-friendly alternating current (AC), battery storage to compensate for unfavorable weather conditions, and a charge controller to regulate battery operation.

Lorentz Pumps- Solar Pumps

LORENTZ was established in 1993 in Hamburg, Germany and they design and manufacture solar water pumps. Lorentz products are used worldwide in rural and urban areas. They work together with the most professional companies in this sector.

Dankoffsolar with their 25 years experience in solar water pumps is just one to name. LORENTZ offers the widest range of surface and submersible solar water pumps in the market and they provide one of the most efficient and durable pumping solutions available.
