“…Participatory processes constitute a widely applied strategy to identify these barriers and propose alternatives to overturn them [41][42][43][44]. Concerning only the quantitative factors of the economic potential, existing literature relies either on cost-related or on investment attractiveness figures [45]. The levelized cost of electricity (LCOE) is the widest used cost-related indicator, but is also target of strong criticism [46].…”

Technical, Economical and Social Assessment of Photovoltaics in the Frame of the Net-Metering Law for the Province of Salta, Argentina

Central and Northern Argentinean regions possess a high potential for the generation of solar energy. The realization of this potential is an alternative to alleviate the strong dependence on imports of fossil energy and to reduce the CO 2 emissions of the country. However, the adoption of photovoltaics (PV) is still in an incipient state. It is undermined by a context of heavily subsidized electricity prices, high equipment and installation costs and a lack of information, training and experience in handling PV technology. This paper presents a techno-economical assessment of the application of the recently enacted net-metering law for promoting renewable energies (RE) in the Province of Salta (Northwest Argentina) for the case of PV. The assessment shows under which conditions and for which types of consumers it is profitable to adopt PV in the context of the law. This analysis is supported by a participatory planning approach as a study of stakeholders' attitudes towards RE, intentions to adopt PV and their knowledge about the law. The results of this study and the economical analysis serve to provide recommendations aimed at increasing the level of PV adoption in the province.

“…Recent European studies focus mainly on PV usage in office and commercial buildings [25,26] as well as in single-family residential buildings [27][28][29]. A recent German work performs a techno-economic analysis of rooftop photovoltaic self-consumption for different building types, including multifamily buildings [30].…”

This paper analyses the profitability and business models of shared, nonsubsidized PV systems' usage in multiapartment buildings in Austria in the context of legislative amendments which came into force in July 2017. In addition, it compares the Austrian results with those of Germany, where significantly higher retail electricity prices determine the profitability benchmark. To that end, a multiobjective optimization model is developed for the optimal dimensioning of PV systems and energy storage facilities in keeping with different end user objectives, ranging from minimizing annual electricity costs to maximizing self-consumption. The results show that the profitability of shared use of nonsubsidized PV systems is marginal in Austria. This means that, based on individual apartment load profiles, the profitability gap ranges between 0 and 40 euros per apartment, whereas the consideration of the building as total load leads to a small cost-saving potential of about 90 euros for the whole building in the best case and thus profitability. In contrast, significant profitability of shared PV systems in multiapartment buildings can be achieved in Germany, where the renewable energy surcharge results in high retail electricity prices. At present, different business models, accounting and billing concepts, are being tested in these countries to learn about the best-practice concepts.

“…A high IRR value indicates that the investment opportunity is favourable, and it should be higher than the discount or interest rate. The IRR has the advantage of considering the time value of money and may be used to compare locations since it does not use the regional discount rates [10]. The IRR formula is presented in equation 3.…”

Abstract-Following recent trends in the developed countries, Portugal recently cut down the Feed-in tariffs for photovoltaic energy. They are now based on the Iberian market average (around 0.04€/kWh) while the final consumer electricity price is 0.16€/kWh. In this view, the PV system should be dimensioned for self-consumption since injecting into the grid produces less revenue. The motivation for the current work was to analyse the changes due to this new regulation, through the analysis of the economic feasibility of different size PV systems (1kW, 3kW, and 5kW), considering the selfconsumption regime with a battery bank as an option. We also compare the most profitable cities in Portugal with and without the use of a battery bank. The results show that the PV systems with battery banks are not as profitable as standalone PV systems in the Portuguese self-consumption regime. This is mainly due to the high price of the battery bank. In general, the mainland results are better than the islands for the 1kW and 3kW PV systems. In spite of the higher initial investment cost, the islands present better results for the 5kW PV system. In general, it can be stated that the investment in PV systems is highly conditioned by external economical factors that continuously change and the current work analyses the current situation in Portugal for different installed powers with or without battery banks.
