“…Figure 6 shows that the model accuracy is the same, equally high, in each of these days. , V e = 0.49 m 3 . Thus, a very important attribute of the model can be concluded from this: whatever the solar radiative regime, the numerical model estimates with accuracy the daily volume of the water pumped.…”

“…In the last two decades there was a constant interest in modeling of such direct-coupled PV pumping systems. A multi-step optimization procedure to improve utilization of a direct-coupled PV water pumping systems is presented in [3]. The algorithm used long-term meteorological data recorded in-situ and data provided by the manufactures for the system components.…”

ARTICLES YOU MAY BE INTERESTED INIntroducing new design and performance points for photovoltaic water pumping systems based on long-term field data analysis Journal of Renewable and Sustainable Energy 5, 023135 (2013) Abstract.Results of an experimental and numerical study on a water pumping system are presented in this paper. In this experiment a direct-coupled photovoltaic water pumping system, operating in real meteorological conditions, was fully monitored on the Solar Platform of the West University of Timisoara. Based on data recorded in this experiment, a numerical model for estimating the pumped water flow rate with respect to the incoming solar irradiance was developed. The model performance in relation with the solar radiative regime is assessed. The results show that that the numerical model tracks with high accuracy the measurement of daily volume of the pumped water, regardless the stability of the solar radiative regime.

“…The studies of Purohit (2007), Firatoglu and Yesilata (2004) Short and Oldach (2003) proved that the financial viability of solar PV energy with respect to the other conventional options, electric or diesel genset, for the pumping of water is the principal barrier which slows down its broad adoption. Kordab (2007) studied the priority options of photovoltaic systems for water pumping in rural areas in the Economic and Social Commission for Western Asia (ESCWA)-the United Nations, member countries by using cost analysis method to determine the cost of the kilowatt hour produced compared with diesel fuel prices during the life of the PV systems (assumed to be 20 years).…”

The current work was based on four selected underground water production wells (W25, W29, W34 and W47), out of 55 wells available in total, at Disi water project located south of Jordan to power underground water pumping using a stand-alone solar photovoltaic (PV) system for an operation period of 25 years. The economic viability of large stand-alone solar PV system of 13 MW in total had been analysed through life-cycle cost computation compared with other four possible powering options, i.e. genset-powered, grid-networked systems, PV-grid and PV-genset. Individual cost banks were identified and studied based on previous practical experiences. Results of the life cycle costs per kWh in the order from the best to worst alternative is the PV (US$0.136 /kWh), PV/grid (0.140), grid (US$0.144 /kWh), PV-genset (0.185), and genset (US$0.239 /kWh), respectively. This proved that the PV solar system is more cost effective and suitable to use over other conventional types of energy for such large power system. Also, payback period analysis was carried out and showed that the PV system is a good option to be recommended highly compared with the other options. Following, the environmental aspects of using clean PV energy were discussed. The resulting savings in CO 2 emission reached 30,000 tons per well throughout the study period, which summed up to about 1.5 million tons of CO 2 for all Disi wells. A briefed risk assessment was conducted for the intended project. Risk levels associated to several hazards were identified as well. The work in this paper can be generalized to other cases worldwide under similar conditions.

“…Therefore, the operating costs of PV powered pumps are relatively low. However, the high initial capital cost of PV array remains the major barrier to their widespread use (Firatoglu and Yesilata 2004). The PV array cost constitutes around 70% of the total PV water pumping system capital cost.…”

Economic viability of photovoltaic, diesel and grid connected water pumping systems is investigated and compared for system capacities in the range 1500 m 4 /day to 100,000 m4/day. Actual performance data from installed systems are considered in calculating systems outputs for base case scenarios. Sensitivity analysis is carried out to generalize results for other locations and conditions. Several scenarios of the effect of variation electricity tariffs, components prices, diesel fuel prices, operation cost and interest rate on the output water unit cost (US$/1000m 4 ) are investigated. Breakeven points of PV pumping systems are determined at certain input parameters.
