SOLAR PUMPS

NEW GENERATION OF SOLAR PUMPING SYSTEMS UP TO 750 HP 30% LESS PVs TO OPERATE PUMPS WITH SOLAR POWER

FOR WATER PLANTS IRRIGATION AND INDUSTRIAL APPLICATIONS

EFFICIENT SOLAR PUMPING Conventional solar inverters (Off and On Grid) are not suited to operate pumps – they would need four separate components (Solar Inverter, Transformer, VFD, and Pump Controller) which translates into 20%-30% of solar power looses. SPI solar pumping technology operates pumps directly from PV plants - it eliminates power conversion loses and eliminates extra equipment costs (see the diagram below). Overall, SPI technology reduces PV requirement by 20% and the solar equipment needs for pumping by 40% .

AWARD WINNING TECHNOLOGY

In 2014, SPI systems were awarded the Prestigious Energy Globe Organization Award for efficient water pumping solar technology and its wide applications in RO plants

ABOUT SOLAROPIA SOLAR PUMPING INVERTER-CONTROLLER (SPI)

Solaropia SPI represents a new generation of solar pumping systems that directly operate pumps up to 750 HP from Solar PV arrays. It does not need use of the grid during day time pumping and automatically switches to hybrid mode (Solar and AC power) during non-daylight hours or early morning when used in 24/h operation. These systems can operate all types of industrial pumps in any application: city scale water plants, sewage plants, large RO plants and irrigation and industrial pumping. SPI embeds five systems in one: Solar Power Inverter, Solar VFD, Pump PLC Application Controller, Pump Communication Controller and Pump Protection and Operation Controller. It is a ‘ready-to-install-and-operate’ heavy duty industrial solar pumping system; first in its class of solar pumping systems that meet vigorous industrial pumping requirements operating in any climate conditions.

BUILT–IN PUMP COMMUNICATION CONTROLLERS • SPI Communicates with other pumps, data servers, PLCs, control rooms

remotely using standard industrial Protocols (Modbus, Profibus)

SOLAR HANDLES DAILY PRODUCTION SPI systems have a great economic advantage – they use solar as the main power and in only 8 hours of operation can handle the required daily pumping volume. SPI systems use the grid (or diesel AC power) only when it is required as a backup (i.e., at night time, late evening). SPI automatically and swiftly switches between solar power and grid power without interruption to pump operation - it uses the two sources simultaneously and economically.

• Pump type independent operates all types of 3-phase pumps (no need to change existing pumps to use SPI technology) • Grid power independent (operates pumps in solar mode from PV arrays) • Operate pumps 24 hours a day (hybrid Solar-AC power sources) • 30% more efficient than commercial solar systems (30% less PV power) • Built-in TFT Touch screen for easy operation • Built-in GPRS for remote operation • Built-in Modbus for plant operation integration • Built-in PLC functions for ready – to use in various pumping applications

*SPI systems operate 15 years minimum with 25 years average solar production.

Pumps consume 70% to 90% of plant operating power representing 60-75% of the plants total operating costs. SPI solar systems significantly reduce pump energy and equipment costs by 50%-to-70%. The economy of operating a 50 HP pump, for example, is provided below to compare SPI cost (average ₵8 per KWh), with diesel power plant (average ₵22 KWh), and utility power (average ₵18KWh). SPI saves approximately 75% of diesel plant operating cost and 55% of grid power costs to operate the same pump.
