“…With a low power of the installation, the self-consumption of the produced energy will occur practically always [54] while with the rescaling of the installation, the degree of self-consumption of electricity decreases and, at the same time, the self-sufficiency increases [18,55]. Apart from the power of the installation, the very degree of correlation of the profile course, while maintaining the conditions for which they were determined, remains approximately constant.…”

Previous analyses of the PV market (and the impact of the pandemic on it) have focused on the market as a whole. The literature does not contain analyses of selected services sectors (e.g., catering, hotel services) in terms of the use of photovoltaics. There are no studies that would show in which segments the demand profile for electricity most closely matches the production from photovoltaic installations (not to mention the impact of the pandemic). The authors analyzed selected service sectors (catering and hotel) in terms of the use of photovoltaics before and during the COVID-19 pandemic. The paper proposes a comparative methodology for the use of photovoltaics for self-consumption, including statistical analyses and calculations of the self-consumption index for representatives of various selected services sectors. The highest value of the self-consumption ratio at the level of 52% was shown for cafes and restaurants (during the pandemic). Surprisingly, in the pandemic, the self-consumption rate increased for restaurants and cafes for the same size of installations (compared to pre-pandemic times).

“…This approach was also chosen for its utility in a wide range of potentially installed PV capacities. With the low power of the installation, self-consumption of the produced energy will almost always occur [24], while, with the rescaling of the installation, the degree of self-consumption of electricity decreases and, at the same time, the self-sufficiency increases [29,30]. Regardless of the power of installation, the degree of correlation of the profile, while maintaining the conditions for which they were drawn, remains approximately constant.…”

In Poland, a dynamic increase in the share of renewable energy sources in the national energy mix has been observed in recent years. Until now, these were mainly installations used for the needs of single-family houses and large-scale installations used on the RES auction market. However, due to the fact that the carbon footprint of the offered products is taken into account, this aspect is becoming more and more important. The carbon footprint can be offset by, among others, by covering the energy needs of the industrial plant by its own renewable energy sources. The article analyzes four sample electricity demand profiles of production plants operating in the mining industry, mainly located in Upper Silesia. Using statistical methods, the fitting of potential photovoltaic sources production profiles to the electricity consumption profiles in the analyzed case studies was checked. The analysis was carried out for each hour of the day and for the profiles weighted by the electricity price from the Polish Power Exchange on the Day-Ahead Market, because matching profiles at different hours has a different monetary value and, as a result, a different impact on operation costs. The highest correlation coefficient between electricity consumption and insolation on an annual basis was −0.29 in the Spearman rho-statistic for the case of M1 enterprise. On the other hand, the highest value at the level of 0.48 was achieved by the Pearson r-correlation coefficient determined on a monthly basis between the monetary value of electricity consumed and insolation in June for the M2 enterprise.

Increasing energy security in the face of rising energy demand and declining funding for fossil fuels has necessitated the diversification of energy supply and the shift to renewable energy. Sustainable management of energy supply is aimed at achieving a low-carbon intensity of production, especially in energy-intensive industries, including the mechanical-engineering industry. The article examines the possibility of shifting the current mechanical-engineering enterprise system and the technical, environmental and economic indicators of production to the new concept of the green economy, which will be an alternative to the further sustainable development of the industry. This article analyzes key approaches to energy conservation. An analytical model has been developed for calculating the energy risk of the mechanical-engineering enterprise and has built a context diagram of mechanical-engineering production, taking into account the environmental impact and the possibility of energy modernization, which allows the setting of strategic goals to ensure the sustainability of energy supply in the mechanical-engineering industry and develop the main principles of efficient enterprise activities in the context of increased risk. It has been proven that one of the criteria for increasing the profitability indicator is the adaptability of enterprises to external conditions and increasing alternative options for obtaining energy from our own autonomous sources.
