“…For a better quality in the comparison of the energy performance of different energy solar systems, it is important to consider that electricity and heat have distinct energy grades. This fact is particularly relevant in conventional and hybrid configurations with the capacity to simultaneously produce electric and thermal energy because it requires the utilization of different amounts of primary energy to obtain useful thermal or electric energy from fossil sources [153][154][155]. One useful metric that considers the different energy grades of electricity and heat is the primary energy-saving efficiency (η f ) [153,156].…”

Process heating is the activity with the most energy consumption in the industrial sector. Solar heating (SH) systems are a promising alternative to provide renewable thermal energy to industrial processes. However, factors such as high investment costs and area limitations in industrial facilities hinder their utilization; therefore, hybrid systems that combine two different solar thermal or photovoltaic technologies where each technology operates under conditions that allow a higher overall performance than conventional configurations have been proposed. In this review, we discuss the limitations of conventional SH systems and the potential of hybrid configurations to overcome them. First, the current literature about conventional and hybrid systems is presented. Then, the application of common performance indicators to evaluate hybrid configurations is analyzed. Finally, the limitation, advantages, and potential applications of conventional and hybrid systems are discussed. This work shows that conventional systems are the most promising alternatives in low and high-temperature industrial applications. At the same time, in medium and processes, hybrid configurations have great potential to increase the performance of SH systems and help to boost their adoption in the industrial sector. There are few studies about hybrid systems in industrial applications, and further research is required to determine their potential.

“…Biomass is another promising renewable source broadly utilized in modern homes, especially for cooking, lighting, and heating purposes. Several research studies have discussed biomass energy and its applications [107] , [108] , [109] , [110] . Biomass power generation presently employed in modern homes is biomass gasification generation, biogas power generation, and biomass combustion.…”

“…Its application has been shown to be difficult due to the variable quality of individual modules and inadequately described interconnections. Berković-Šubić et al [14] presented calculation methods implemented into Croatian Algorithms for calculating the energy performance of a building based on the standards EN ISO 13790:2008 andEN 15316:2008, and proved that overwhelming parts of available methods from standards can be successfully applied if certain improvements and modifications to the original calculation procedure are applied. Horvat and Dović [15] compared the results obtained by these methods to those obtained with their own developed dynamic model, and differences of up to 33% were found in the analysis of individual subsystems.…”

This paper presents the methodology for conducting a cost-optimal energy performance calculation of a solar hot water system, used for space heating and domestic hot water needs. The calculation is based on dynamic hourly methods, according to the new Energy Performance of Buildings’ (EPB) set of standards EN 15316:2017, and a revision of the standard EN 15316-5:2017 from the year 2021, dealing with storage-tank water temperature calculations. The paper provides proposals for modifications to these newly introduced standards, in order to overcome the observed ambiguities and shortcomings. The calculation of annual energy performance of a building was performed on an hourly basis over a year for the reference of an nZEB multi-apartment building, for a climate area of the city of Zagreb, taking into account water temperature change in the layers of the storage tank connected to solar collectors and hot water boilers. The cost-optimal solution was then determined by varying individual parameters of the building technical system. The influence of these parameters on the energy efficiency of the building was analyzed in detail. Furthermore, the results were compared against those obtained by the Croatian calculation algorithm based on the previous set of EPB standards, EN 15316:2008, currently used EU-wide for the energy performance certification of buildings. The results indicated that the calculation methods of the present algorithm underestimated the consumption of building primary energy by 12%. The energy delivered by solar collectors was underestimated by 18%.
