“…Feed-in tariffs for different PV sizes, P PV (installed power, in kW), are assumed as granted in Germany in 2019. 3 Electricity prices for municipalities are based on a survey of actual contracts that were available to the authors in the course of this study. In line with current German regulation, a surcharge rate of 27.5 EUR/MWh is due if electricity is used from an own PV plant, if that plant is supported through a feedin tariff.…”

“…The authors of [2] calculate SCR and SSR for different sizes of PV rooftop systems and battery storage, based on a reference household load profile. A model to estimate the internal rate of return for different PV plant and battery sizes, using simulated household load profiles, is developed by [3]. The authors of [4] determine the cost optimum constellation of PV system size and storage capacity, by varying both parameters.…”

The increasing gap between electricity prices and feed-in tariffs for photovoltaic (PV) electricity in many countries, along with the recent strong cost degression of batteries, led to a rise in installed combined PV and battery systems worldwide. The load profile of a property greatly affects the self-consumption rate and, thus, the profitability of the system. Therefore, insights from analyses of residential applications, which are well studied, cannot simply be transferred to other types of properties. In comparison to residential applications, PV is especially suitable for municipal buildings, due to their better match of demand and supply. In order to analyze the value of additional batteries, municipal PV battery systems of different sizes were simulated, taking load profiles of 101 properties as inputs. It was found that self-consumption differs significantly from households, while different types of municipal buildings are largely similar in terms of the indicators analyzed. The share of electricity consumed during summertime was found to have the most significant impact on the self-consumption rate for most considered system sizes. Due to lower electricity tariffs and lower increases in self-consumption provided through batteries in municipal buildings, the investment into a battery is not economically advantageous in most of the cases considered.

“…Small systems are often more expensive and have led to increase in PV total cost in the residential sector. Another study [13] presented a simulation model to identify most profitable PV system size and storage for residential usage. Germany and Ireland are compared to explore what drives the profitability of self-consumption and self-sufficiency in different countries.…”

Original scientific paper https://doi.org/10.2298/TSCI180305302YThe optimum sizing of photovoltaic technologies depends on certain variables such as the daily energy consumption of buildings and available solar potential of the location. The purpose of this paper is to define the optimum photovoltaic panel area with no battery system to supply the daytime electricity usage of a Vocational School in Sanlıurfa, Turkey. First, the maximum photovoltaic panel areas are found at the 100% self-consumption for the Mono-Si, Multi-Si, and CdTe photovoltaic technologies. Besides, for defining optimum installation powers, an economic analysis has been carried out. The seasonal performances of economical optimum capacities are investigated under the feed-in tariff scenario. At 100% self-consumption, the maximum photovoltaic panel areas are found 130 m 2 , 160 m 2 , and 170 m 2 for Mono-Si, Multi-Si and CdTe respectively. The results show that the installation of Mono-Si (115 m 2 ), Multi-Si (150 m 2 ), and CdTe (210 m 2 ) photovoltaic systems at 1.65, 1.75, and 2.3 times as the daily peak electricity consumption, is the most optimal selection according to economic indicators.

“…Bertsch et al [29] analyse the investment in household PV systems with batteries, finding that such systems may decrease grid electricity uptake by 75% in Germany and 65% in Ireland, however, only focusing on "PV and storage systems from a household perspective". Khalilpou & Vassallo [30] investigate the feasibility of batteries in grid-connected PV systems in Australia, finding that only low-cost batteries are feasiblethough there is a strong sensitivity to solar radiation, electricity prices, system costs and system specifications.…”

Highlights-EnergyPLAN simulations of residential and communal batteries in combination with PV -Residential PV and battery set-up enables higher self-supply and customer involvement -Communal battery set-up leads to higher share of electricity fed to the grid -PV and batteries improve demand side management, balancing and production planning Abstract This paper presents an analysis of small consumers' involvement in smart island energy systems with a focus on the technical feasibility of photovoltaic (PV) systems in combination with batteries. Two approaches may be observed in the literature: the optimization on a household level with the aim of being self-reliant versus coordinated and collective technologies with increased integration across sectors and energy carriers. Thus, for household systems, the placement of a batterywhether aggregated or residentialcreates the basis for this investigation. The study is based on the case of the Danish island Samsø for which the two battery approaches are simulated using the energy system simulation model EnergyPLAN. Results indicate a tendency towards aggregated batteries being more favourable from a systems perspectivewhile on the other hand, residential batteries are more motivating and involving the consumers. The importance of minimizing flows to and from the grid as a result from fluctuating energy sources is addressed in both approaches. While residential batteries improve the individual household electricity supply, a communal battery would further regulate other inputs and demands. * Corresponding author [2]
