“…They can be implemented in an easily maintained, directly coupled (battery-free) configuration, thereby avoiding one of the major pitfalls of photovoltaic (PV) use in the developing world (20). Though PV systems are often dismissed out of hand due to high up-front costs, they have long lifetimes, and in the medium-term, cost less than liquid-fuel-based pumping systems, particularly in areas where stable access to fuel is limited (21,22).…”

Meeting the food needs of Africa’s growing population over the next half-century will require technologies that significantly improve rural livelihoods at minimal environmental cost. These technologies will likely be distinct from those of the Green Revolution, which had relatively little impact in sub-Saharan Africa; consequently, few such interventions have been rigorously evaluated. This paper analyzes solar-powered drip irrigation as a strategy for enhancing food security in the rural Sudano–Sahel region of West Africa. Using a matched-pair comparison of villages in northern Benin (two treatment villages, two comparison villages), and household survey and field-level data through the first year of harvest in those villages, we find that solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies.

“…This study developed a simple framework and estimated unit cost of water and unit cost of useful renewable energy. Odeh et al, (2006) studied on the economic viability of a photovoltaic water pumping systems and compared with the diesel engine pumping system and found that off-grid water pumping by using solar energy was a viable option. This paper presents both technical and economic analysis of solar irrigation systems installed in Bangladesh.…”

In the summer season, irrigation sector in Bangladesh suffers a lot due to the country wide electricity crisis. Solar pump offers a clean and simple alternative to the conventional fuel fired engine or grid electricity driven pump in this regard to resolve the issue. In this paper, the techno-economic analyses of solar irrigation plants installed in Bangladesh are evaluated. It was observed that systems were running around 70% to 80% of the rated power which was quite acceptable. A 10 hp pump was able to pump 600 liter of water per minute which was also satisfactory to irrigate the land. Average operating time was found to be 8 hour/day. It was found that the overall efficiency of the systems were in between 11.39% to 16.52% whereas the typical average value of lit/Wp/year was 9200. On the other hand, the cost of irrigation to cultivate paddy in 0.161 hectares’ land for one season was 1,750 BDT by solar irrigation which was found to be lower than that of other available modes. This charge for grid electricity based irrigation was about 3,000 to 3500 BDT per 0.161 hectares’ and 2,300 to 2,600 BDT per 0.161 hectares’ for diesel engine based irrigation. According to the current financial scheme (15% equity investment, 35% credit support and remaining 50% from government through IDCOL) the average value of payback period was 5.43 years, NPV in the range from 7 to 15% and IRR was 18%. By considering 100% equity investment, however, these projects were not economically attractive. The payback period for this case was about 18 years. Study also revealed that each solar irrigation plant reduces 42.8 kg of CO2 emission per day compare to diesel engine operated pump and 2566.24 kg/day compared to grid electricity operated pump. A comprehensive effort from the Government as well as from all the stakeholders is required for further expansion of solar irrigation plants in Bangladesh.

“…Several papers regarding these issues were found in the open literature and are summarised as follows: Thomas (1993) stated that the method of the life cycle cost (LCC) is an efficient method to be used to evaluate the financial viability of a PV water pumping solar system. Senol (2012), Abu-Aligah (2011), Mahjoubi et al (2010), Odeh et al (2006), Mahmouda and Natherb (2003) and Kolhe et al (2002) all studied the economical aspects of solar photovoltaic (PV) water pumping compared to diesel genset, by using the method of LCC. The results indicated that the PV solar water pumping, in terms of cost, is better than the diesel pumping systems.…”

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.
