“…From Equations ( 15)-( 17) it is possible to perform an hourly balance, integrating the power values obtained for each hour h of the representative days of each month m of the year, through Equations ( 18)- (20) in which the factor 1/6 represents the time in hours of which each instant considered is representative.…”

“…In the literature there are also methodologies that abound in the number of residents of each household. Escobar et al [20] establish a ranking based on this methodology, as well as on the regulations of several European countries, highlighting the case of France. The complete work developed by Gimeno et al [21] which, although it focuses empirically on Spanish facilities, establishes a methodology that encompasses the barriers and incentives that prosumers find at various levels (economic, technological and regulatory) in southern European countries and Germany.…”

Simulation of Self-Consumption Photovoltaic Installations: Profitability Thresholds

et al. 2021

PV self-consumption can contribute positively to the spread of PV and, therefore, to the progress of renewable energies as a key element in a decarbonized energy model. However, the policies of each country regarding the promotion of this type of renewable technology is fundamental for their growth. Despite the high number of sunshine hours registered in Spain, self-consumption in this country has not been authorized until recently. In this new context, this work presents a systematic study of the profitability limits of a self-consumption PV installation under different conditions of installed peak power, orientation and inclination of the PV panels and level of obstruction of the installation. It was proved that, for the case of study (Córdoba, Spain), the maximum profitability was achieved for PV panels oriented to the south and with an inclination of 15° whereas the most unfavourable conditions are those of PV panels with an orientation and inclination of 180° and 90°, respectively. Furthermore, when the level of obstruction increases the maximum of the Net Present Value of self-consumptions PV installations decreases and this optimal value is achieved for installations with lower power. Finally, empirical adjustment equations have been developed to estimate the profitability parameters of self-consumptions PV installations as a function of their design variables.

“…The impact of the new self-consumption regulation on prosumers in Spain has captured a considerable attention, both in the non-academic literature [17,18] and in the academic one [19][20][21][22]. At the same time, the impact of the new PV self-consumption regulation on the profitability of prosumers has been analyzed taking into account the evolution of installation costs, the opportunities of shared self-consumption or storage, and even the potential emergence of new business models [19].…”

“…In the case of the residential sector, although it has the lowest profitability level, it has the highest potential to increase the share of self-consumption, given the decreasing installation costs and the higher retail prices [19]. The profitability of photovoltaic self-consumption installation in Spanish households has been also studied, taking into account the number of members of the household and comparing the Spanish regulation with the self-consumption support policies in other countries (France, Germany, Italy, Great Britain, and Finland) by scaling up the incentives provided in those regulations to the Spanish price [20]. The result is that all these regulations present significantly better profitability than the Spanish one.…”

“…The result is that all these regulations present significantly better profitability than the Spanish one. For instance, the payback period in Spain for households of 1-4 members is 21, 17, 16, and 15 years, respectively, while in the worst of the other analyzed countries these values are 13, 11, 10 and 10 years [20]. Finally, in [21], the case of collective self-consumption in residential buildings under the new Spanish regulation is analyzed.…”

The reduction of equipment costs encourages the diffusion of photovoltaic micro-generation, however, proper regulatory measures should be implemented to facilitate self-production dissemination and to promote the emergence of new electricity markets which integrate prosumers. The specific form of these markets will depend on the level of prosumers’ self-sufficiency and the type of grid to which they will be connected. Unfortunately, Spain has been an example of resistance to micro-generation deployment. However, some things have started to change recently, albeit only to a certain extent. This article explains the key elements of the latest regulation of photovoltaic micro-generation in Spain and, through a stylized model, describes the economic behavior of prosumers in such a regulatory framework. It is concluded that this regulation only encourages prosumer plants which are strictly focused on self-sufficiency because it discourages exports and limits capacities and this regulation discourages the smart renewal of the distribution grid because it prevents prosumers from participating in the electricity market. It is recommended that the aforementioned regulatory limits be removed and pilot experiences for the market participation of prosumers be promoted by creating the appropriate technical and regulatory conditions, for example, at the municipal level.
