Since 2009, Shenzhen Solartech solar pumping system has been installed in Turkey. In May 2019, ten solar pumping systems were installed and operated at the orchard farm in Konya Province, Turkey, replacing traditional diesel power generation. For the first 6 years, the cost of water of solar pumping systems is less than 1/3 of the diesel generator’s. Based on the 25-year service life, the water cost per ton of solar pumping system is only 0.027 USD.

 

 

 

Konya province is located in south-central Turkey and is the main agricultural center of the Anatolian Plateau, at an altitude of 1027 meters and a population of about 2.1 millions. Agricultural irrigation water is often under strain during the dry season due to the low average annual precipitation and uneven seasonal distribution in the region. The main local farms are far from the urban area, the electricity supply is highly unstable and the electricity bill is very high. Farmers need to be equipped with large diesel generators to power pumps and pump water to meet irrigation water, which is not only expensive to operate and maintain, but also contributes to some pollution of the local environment.

 

 

The Turkish orchard irrigation project equipped with 5.12kW solar PV power, the water head is 60 meters, daily water flow is 75 tons and the altitude is 1027 meters. It uses full stainless steel 3kW AC submersible pump. The average purchase and construction cost of a solar pumping system is equal to that of diesel generator with the same water output. Only the pump needs to be replaced and maintained in the first 6 years while the main equipment does not need. The average unit cost of water consumption in 6 years is 0.0.34 USD / ton.The total water output is 685,000 tons in 25 years, and the average cost of water per ton is only 0.027 USD.It saves 80% cost than diesel power’s.

The system is equipped with Solartech PB solar pumping inverter, with Dynamic VI maximum power point tracking (MPPT) algorithm and optimized SPWM control method. Faster speed of response and good stability. Fully automatic operation. Pump operation frequency range can be set based on project requirement. Support soft start of pump. Full motor protections. Optional water level switch to protect overflow and dry running. Multiple DC input strings can implement solar combiner function, anti-reverse circuit at each input string. 8 years storage capacity for operation data.
 

 

Solar pumping system is ready to use. Automatic operation and no need to pay electricity bills. No need grid network or water channels. Water storage instead of electricity storage and no need energy storage batteries. 53.23 tons of diesel could be saved in 25 years of project operation.
