“…FIT, net-metering or net-billing programs are very competitive [15,25,46,51]. However, without support in the form of feed-in tariffs or other preferential tariffs, PV systems, among them residential ones, would not develop [10,33,38,42,45,46,50,52,53]. Electricity generation costs from PV still do not reach grid parity in many countries, even with lower investment costs [40].…”

Factors Determining the Development of Prosumer Photovoltaic Installations in Poland

The development of energy production from renewable sources includes the production of energy from photovoltaic installations by prosumers. In Europe, RES development is driven by political goals and requires subsidies during the deployment period, at least as long as the cost of renewable electricity does not reaches grid parity. The study attempts to determine the importance of factors in the development of energy production by prosumers from PV installations in Polish regions. In 2019, the ‘Moj Prad’ program was introduced, applying subsidies to investment costs and the settlement of energy production in the net-metering system. Almost 900 thousand prosumer PV installations were built by the end of 2021, with a total capacity of 5.9 GW. Solar energy share grew from 0.1 to 2.1%. Spatial econometrics models were use in research to determine factors of prosumer PV systems development in Poland (at NUTS-2). Spatial regimes were found in the studied regions, as indicated by a positive autocorrelation (0.75). Considering the pseudo-R-square co-efficient, we can conclude that the spatial error, i.e., factors not included in the GNS model, constitutes approximately 10%. The economic variables included in the Mansky model, i.e., level of salaries and GDP, explain 90% of the variability of installed PV capacity (Nagelkerke pseudo-R-squared value is 0.906). The level of development of prosumer photovoltaic installations (in W per capita) in regions depends primarily on economic factors represented by the level of salaries in a given region. With the increase in salaries by one unit, we also have an increase in installed power capacity in watts per person by 3.52. Surprisingly, the region’s overall wealth did not matter, as the relative number of installations in regions with lower GDP was higher than in others. One can explain that the individual income of households is more important for increasing the number of prosumer installations than the income of the regional economy. The increase in the number of installations in one region contributed to the subsequent increase in their number in neighboring regions.

“…However, installation of solar PV has encountered local resistance due to a number of issues, including lack of environment impact assessment, unsuitable land being assigned, and lack of transmission lines [36]. Taiwan's NZE plan will install 20 GW of solar PV capacity by 2025, with 8 GW on rooftops and 12 GW on the ground [39]. As of 2021, only 7.7 GW of solar PV capacity has been installed (Figure 13) [24], mostly by IPPs [41].…”

“…Chen et al ( 2010) estimate it to be 65 TWh/y [72], Yue and Huang (2011) estimate it to be 36.1 TWh/r [73], and Ko et al (2015) estimate it to be 15.4 TWh/y [74]. It is unlikely that solar PV will reach 20 GW by 2025, as per the NZE plan, due to space limitation, high capital investment, and decreasing feed-in tariffs [39]. 7.1.9.…”

The objective of this paper is to propose a decarbonization roadmap for Taiwan to achieve net-zero emissions by 2050 by analyzing the status of fossil and non-fossil energies, screening applicable decarbonization technologies for their effectiveness, and then proposing an energy mix for the future. The novelty of this work lies in the screening process, which considers six, instead of one or two, categories: sustainability, security, affordability, reliability, technology readiness, and technology impact. Based on this screening, a decarbonization roadmap is proposed and compared with the announced net-zero emissions (NZE) plan. The proposed roadmap requires renewable electricity to grow at an average annual growth rate of 7% between now and 2050, instead of the 10.1% required by the NZE plan, which is more achievable based on issues identified with renewable energies during our screening exercise. The proposed roadmap improves on the NZE plan in the following aspects: (1) using clean coal technologies to decarbonize existing coal-fired power plants, (2) relying more on gas than wind and solar energies to replace coal and nuclear energy for power generation, (3) accelerating carbon capture and storage (CCS) implementation, (4) delaying the phaseout of nuclear energy until 2050, and (5) using blue instead of green hydrogen to decarbonize the transport and industry sectors. Implications of this roadmap for future research and development and energy policies are also discussed.

“…These studies are also reliant on what is considered, namely, the use of storage systems, whether the produced energy can be sold and on financial incentives. So, studies associated to specific countries have been made, such as Portugal [3,6], Spain [7,8], USA [9], Australia [10,11], Italy [12], Germany [13], Republic of Korea [14], Taiwan [15], Peru [16] and Chile [17] and Namibia [18]. From the several studies, it was concluded that SC is now a very interesting solution, being considered already profitable.…”

Financial Analysis of Household Photovoltaic Self-Consumption in the Context of the Vehicle-to-Home (V2H) in Portugal

et al. 2023

This paper focuses on the purpose to see if it is possible to increase the earnings associated to the installation of PV systems in people’s homes. In accordance with this, a different way of thinking was adopted, namely the investment in batteries to maximize the energy earnings. The main problem of this classical approach is that the investment in those batteries is important. In this way, a different perspective was taken into account, namely the use of the electrical vehicles. This kind of vehicles is starting to become a real reality. In fact, the selling of these vehicles start to become a solution for the ordinary people, and it is expected in a very near future to be a reality for most of them. Thus, this study presents the use of a storage system based on the vehicle-to-home (V2H) technology for the people’s homes. The V2H availability varies among prosumers profile regarding the daily routines, weather conditions, and business aspects, besides other aspects. These profiles were combined with different power panels with and without injection into the grid. The costs of each configuration considering a residential consumer located in Portugal, as well as, their peak solar hours in a year were estimated. From this study, it will be possible to verify that the obtained economical results show that the usage of V2H as storage system based on batteries for modern homes is very attractive.
