“…When choosing the optimal solution, the following table might be helpful, but obviously, there are many other details to be taken into consideration, such as the location, the number of possible members of the association, the current status of the nearby irrigation channel, etc. [76][77][78]. The aforementioned features (see Table 1) of the possible implementation solutions are explored in the next sections of this study and compared with the proposed solution.…”

Traditionally, the energy industry has been slow in adopting new disruptive technologies and the transition to a new energy market will require a new digital transformation plan, involving all parties from the energy market. Although it now seems to be an impossible and hard-to-accept scenario, especially by the big players in the industry, the pilot projects so far demonstrate that blockchain can play a major role in the future energy market, even if the technology is still in the first stages of the adoption life cycle. This article attempts to describe a solution to provide alternative irrigation systems for small farmers. The solution involves creating associations of small farmers that will use green energy from photovoltaic panels for the irrigation of agricultural lands. The efficiency of the proposed system can be monitored not only through digital hardware connected to photovoltaic panels and water pumps, but also by using the new blockchain technology that stimulates innovation and growth in the energy and a high level of automation though smart contracts. To accelerate the transition to the green energy economy, a SolarCoin version similar to the Bitcoin cryptocurrency has also been proposed, which is a utility token that creates new possibilities for energy and water trading.Sustainability 2020, 12, 1540 2 of 30 photovoltaic panels can still be used at high capacity to supplement the energy required to run the farm [4,12,13].Photovoltaic systems are ideal in isolated areas that do not have access to the national energy system. Below, the most important advantages of applying the photovoltaic systems in agriculture have been listed [14-16]:

“…However, even this effect of high specular reflection is found to be insignificant for modules at larger tilt angles in an earlier study. 11 Lower water surface albedo will have implications on bifacial module performance on water. This will be discussed later.…”

The interest in floating photovoltaic (FPV) power plants has grown rapidly in recent years. In many established and emerging markets, such as Japan, South Korea, UK, China, and India, FPV is already considered as an attractive and viable option for PV deployment. In 2016, Singapore launched the world's largest FPV testbed, with a total installed capacity close to 1 MWp. This testbed aims to study the economic and technical feasibility, as well as the environmental impacts of deploying large‐scale FPV systems on inland fresh water reservoirs. The testbed currently consists of 8 systems, with different configurations in terms of PV modules, inverters, and floating structures. The field experience of deploying, operating, and maintaining these systems, together with a comparison of their performance and reliability offers highly valuable learning points for the FPV community. In this work, we present extensive, high‐quality field measurement data; compare operating environments on water and on a rooftop; analyze system performance of different FPV systems; and share some issues encountered. We found that FPV does confer some performance benefits, but best practices should also be established to avoid new issues and pitfalls associated with deploying PV on water.

“…Floating photovoltaic (PV) systems are PV systems that float on the surface of dam reservoirs, quarry lakes, irrigation canals, or tailing ponds [1]. Recently, the market for floating PV systems has drastically expanded worldwide because of their several strengths compared with PV systems installed on land.…”

“…Sahu et al [6] investigated the status and various design options (e.g., types, concepts, and commercial design) of floating PV power plants worldwide. Cazzaniga et al [1] reviewed performance analyses and design solutions for floating PV plants. Some work [7,8] has been done to estimate EPOs from floating PV systems by simulation, taking into account local meteorological data, physical characteristics of modules and inverter, and system design.…”

Comparison of Electric Power Output Observed and Estimated from Floating Photovoltaic Systems: A Case Study on the Hapcheon Dam, Korea

An interest in floating photovoltaic (PV) is growing drastically worldwide. To evaluate the feasibility of floating PV projects, an accurate estimation of electric power output (EPO) is a crucial first step. This study estimates the EPO of a floating PV system and compares it with the actual EPO observed at the Hapcheon Dam, Korea. Typical meteorological year data and system design parameters were entered into System Advisor Model (SAM) software to estimate the hourly and monthly EPOs. The monthly estimated EPOs were lower than the monthly observed EPOs. This result is ascribed to the cooling effect of the water environment on the floating PV module, which makes the floating PV efficiency higher than overland PV efficiency. Unfortunately, most commercial PV software, including the SAM, was unable to consider this effect in estimating EPO. The error results showed it was possible to estimate the monthly EPOs with an error of less than 15% (simply by simulation) and 9% (when considering the cooling effect: 110% of the estimated monthly EPOs). This indicates that the approach of using empirical results can provide more reliable estimation of EPO in the feasibility assessment stage of floating PV projects. Furthermore, it is necessary to develop simulation software dedicated to the floating PV system.
