“…According to [29], BIPVs are 1.46 times more expensive than regular PV modules due to their customized design. The lifetime of PV is assumed to be 25 years regarding the warranty duration of PVs [30]. 1 the cost is estimated from the market price of BIPV [29]; 2 The costs include the building permit fee and the fee for linkage to the existing electric distribution system; 3 the cost estimates from [31].…”

Building integrated photovoltaics (BIPVs) are becoming popular as building elements such as windows, roofs, and outer walls. Because BIPVs have both a construction material function and an electricity generation function, they are a promising alternative to sustainable buildings. This study aims to propose a novel agrivoltaic system design that produces crops underneath photovoltaic (PV) modules. Regarding the fact that crop growth is significantly influenced by shading from PV modules, roof BIPVs with different shading ratios can lead to increased crop productivity. Thus, BIPV design should be investigated based on the performance estimation and feasibility evaluation of different shading ratios in an agrivoltaic system. To this end, electricity generation and crop production models are devised by polynomial regression (PR) based on field experiment data collected from the agrivoltaic system at the Agricultural Research Service Center in Naju-si, South Korea. The experiment shows that a shading ratio of 30% allows for the maximization of the profitability of electricity and soybean production in an agrivoltaic system equipped with BIPVs. As a result, this research will contribute to implementing an agrivoltaic system with various BIPVs.

Solar energy is presented as the main alternative to conventional energy sources that often rely on burning fossil fuels. However, one major obstacle to its wider adoption is the limited ability to store the energy produced that can only be generated for a few hours daily. One way to overcome this limitation is using photovoltaic energy to power urban water supply pumps. This allows the energy to be stored as potential energy in regulating reservoirs while also taking advantage of the temporal coincidence between the generation of solar energy and the daily and annual water and energy supply consumption. Given that implementing solar energy in pumping devices involves an enormous investment, the optimal payback period is identified as the key indicator to know which population is one in which this action is more advisable. This work aims to find the key factors influencing the payback period of solar photovoltaic installation in urban water supply networks. To accomplish this goal, this study analyzes all 20 municipalities in the province of Alicante (which consume groundwater) where these systems can be implemented. Furthermore, this study facilitates the identification of variables that influence the decision to install a solar photovoltaic system in an urban water supply. By measuring two or three parameters, it becomes possible to easily determine the economic viability of such an investment in towns supplied with groundwater. Furthermore, these results can be extrapolated to other municipalities with similar features (irradiance, inhabitants, etc.). This study also presents a straightforward formula that supply managers can utilize to calculate the payback period of the installation using readily available data. The main factors that affect the recovery period of a photovoltaic solar installation are the difference in monthly supply consumption between winter and summer months and the average water depth.

To meet water demands, pressurised irrigation networks often need pumping devices, whose power demand varies with the pump head, the flow rate delivered and the pump efficiency. To satisfy the energy demand of pumps, solar photovoltaic panels can be used as a renewable energy source. Since the electricity supply of a solar photovoltaics plant depends on irradiance, the energy that powers the pump varies with the time of the day. This study presents a strategy for scheduling water delivery by irrigation pumps, synchronising energy production in solar photovoltaic modules and minimising the installation size. An optimisation algorithm is proposed, which changes the energy required by pumping devices and adjusts them to the available solar energy supply, minimising the number of panels required. This problem applies to a pressurised irrigation network, where the utility manager may irrigate crops at all hours of the day. By adopting the proposed algorithm, irrigation will follow a rigid rotation schedule to follow the new irrigation plan. This approach improves earlier studies by employing a least-square scheduling algorithm with little computing time. This results in a tool for managers and decision-makers when evaluating the possibility of converting their irrigation network into a stand-alone system supplied by photovoltaic panels. A case study handling this issue in the University of Alicante’s pressurised irrigation network in Spain is proposed to find potential energy savings by connecting the recommended scheduling irrigating plan to the present operation.
