Solar Pumping with Lorentz submersible pumps


Many companies are trying to improve their image by using renewable energy. A solar pumping solution is a public and practical use of renewable energy.

LORENTZ is well known as a quality designer and manufacturer of solar pumps. Through innovative electronic controlling, outstanding manufacturing quality and a simple design, Lorentz have managed to reduce the high cost of solar water pumping. Their submersible helical rotor pumps consist of only two parts, Lorentz's brushless motors are water filled and maintenance free, while the electronics are NOT inside the submerged motor but easily accessible on the surface.

The helical rotor solar pump can deliver up to 39,000 litres of water per day, and the centrifugal pump can deliver up to 137,000 litres of water per day. These pumps can lift water up to 240 metres, which is astounding for a solar pump.

Energy Matters provide simple DIY installation kits, plus pumps are virtually maintenance free and come with a 2 year manufacturer's warranty. Each solar pumping system includes Lorentz Submersible Solar Pump, Lorentz PS series controller, motor, plugs for connecting all components, low level switch, splice kit (ie. lugs and heat shrink), and a circuit breaker.

The PS series solar controller manages the pump system and monitors operating states. It is mounted on the surface with no electronic parts submerged. It has two control inputs for well probe (dry running protection), float or pressure switches, remote control, etc. The PS solar controllers also include speed control, integrated maximum power point tracking (MPPT) and battery operation.

The brushless DC motor contains no electronics, and the dynamic slide bearings are made out of carbon and ceramic. The wetted material of the motor is made of rubber and stainless steel and is drinking water approved!

The applications of the solar pump include: irrigation, water bores, pond management, drinking water supply, pond management, livestock watering, topping up tanks. Please contact Energy Matters for more information.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
