“…Data from NASA have been utilized for a case study in Ethiopia [34]. Data from Meteonorm have been used for studies in China on irrigation [13,35] and milk production [36] and for a case study in Morocco [37]. However, to the best knowledge of the authors, the comparison of the impact of inputting satellite data or local measurements on the output of PVWPS models and on their accuracy has not yet been assessed.…”

“…PVWP surplus electricity production and CO 2 emission reductions. The common design approach of PVWP systems for irrigation sizes the PV array for the month that has the highest ratio of IWR to E s [19]. This design procedure has the disadvantage of making the PVWP system oversized for most of the irrigation season due to the variability of IWR, and unused during the nonirrigation season.…”

“…IF is a measure of the energy used for irrigation purposes compared to the total energy produced by the PV array. IF was set equal to 30% based on the results achieved in previous works conducted in different locations in China [6,19,22,33]. If the PVWP system is installed nearby the electric grid, as shown in Fig.…”

“…The main parameters required to design PVWP systems for irrigation are: the monthly average daily peak of IWR, the operational hydraulic head H o , and the monthly average daily solar irradiation hitting the PV array E s . The IWR was calculated from the reference evapotranspiration ET o and precipitation spatial data assuming June as the design month (month marked out by the highest ratio between IWR and solar irradiation hitting the PV array) [19]. The ET o spatial data (10 0 spatial resolution % 20 km Â 20 km at the Equator) was taken from the FAO GeoNetwork database [20].…”

Suitable and optimal locations for implementing photovoltaic water pumping systems for grassland irrigation in China

h i g h l i g h t sA new approach to assess the grassland sites for PVWP irrigation systems is proposed. A spatial explicit optimization model is used to assess the optimal locations. The potentials of PVWP systems for grassland conservation are substantial. The potential of PVWP in carbon emissions reduction is significant. a r t i c l e i n f o a b s t r a c tGrassland plays a key role for the food security of China because of the large number of livestock raised in those areas. Thus, grassland degradation due to climate change and overgrazing is considered as one of the most severe environmental and economic threat for the future sustainable development of China. Photovoltaic water pumping systems for irrigation can play a fundamental role for the conservation of grassland areas. This paper investigates the geospatial distribution of the technically suitable grassland locations for the implementation of photovoltaic water pumping systems. The technically suitable grassland areas were taken as starting point to assess the optimal locations. The assessment of the optimal locations was conducted using a spatially explicit optimization model of renewable energy systems based on the cost minimization of the whole forage supply chain.The results indicate that the photovoltaic water pumping systems provide high potential for improving forage productivity, contributing to meet the local demand. The optimal areas are highly sensitive to several environmental and economic parameters such as increased forage potential yield, forage management costs, forage water requirements, ground water depth, forage price and CO 2 price. Most of the optimal areas are selected when the market forage price ranges from 300 to 500 $/tonne DM, indicating that the forage produced using PVWP technology for irrigation is already competitive compared to the imported forage.

“…Campana et al [43] discussed the technological and economic feasibility of renewable energy systems for irrigation and conservation of farmlands in China, comparing PV water pumping technology to wind powered water pumping systems. Based on the irrigation water requirement (calculated as per FAO [44]), a model was developed to calculate the size of PV and wind powered systems based on varying solar irradiation and wind speeds respectively.…”

This investigation focused on the research undertaken on solar photovoltaic (PV) and solar thermal technologies for pumping water generally for irrigation of remote rural farms specifically considering the Sub-Saharan African region. Solar PV systems have been researched extensively for irrigation purposes due to the rise in Oil prices and the upscaling in commercialisation of PV technology. Based on the literature the most effective PV system is presented for the irrigation of a small scare remote rural farm with respect to the cost, pumping capacity and system efficiency. Similarly, solar thermal systems are reviewed and the most effective system described. Unlike PV technology, solar thermal technology for water pumping is lacking especially in small scale operations. However, with the possibility of local production, low investment cost, easy maintenance and lower carbon footprint, solar thermal water pumping technologies may be able to overcome the shortcomings of the PV technology that has stopped widespread use of the technology for irrigation applications. Taking into consideration recent developments in concentrated solar technologies using the Stirling engine, novel solar thermal water pumping systems may be developed. This review also highlighted the different methodologies such as modelling, used to investigate and optimise the performance of solar powered systems.
