“…The choice for a particular solar thermal system is influenced by the energy consumption, technical conditions, location, and economic criteria. Sami et al [27] published an interesting study regarding the integration of solar thermal systems (water heating) into high-energy performance housing in various regions with distinct climatic conditions in Algeria. The study considered both economic and energy criteria and allowed determining the optimal collector area that minimized the purchase and installation costs.…”

Solar thermal systems have been widely used to increase energy efficiency in the building sector, since the use of renewable energy sources became one of the top priorities to meet environmental targets. The main objective of this study is the thermo-economic optimization of solar thermal systems for residential building applications, considering a multi-objective approach. The simulations were performed through a MatLab code by implementing an elitist variant of Non-dominated Sorting Genetic Algorithm-II (NASGA-II). The solar collection area and the linear loss coefficient as well as the tank storage volume were defined as decision variables. A two-dimensional Pareto front was obtained, considering as objective functions the minimization of the annualized investment cost and the maximization of the solar collection efficiency. Based on the best trade-off between both objectives and considering that the solar thermal systems can operate for a period of at least 15 years, the Pareto analysis led to the conclusion that a system with an annualized investment cost between 270 and 280 €/year allows reaching a collection efficiency of 60%. After the analysis of the optimal solution points, a configuration was selected to estimate the system total purchasing cost: a panel with a solar area of 4.17 m2 and with a linear coefficient loss of 3.684 W/m2.K; a storage volume of 0.275 m3; and a pump flow rate of 0.1364 m3/h. For this configuration, we estimated a total purchasing cost of 2545.0 €, whereas the solar collector and the storage tank are the most expensive components, representing a share of 42% and 43%, respectively. These results represent a specific cost of 610.3 €/m2 per solar collection area.

“…Even if the needs are met in the summer months, they must be supported with auxiliary energy sources for the winter months or times when there is no Sun. erefore, solar powered heating systems can be projected in a way to provide fuel saving and decrease the cost of hot water [70,72].…”

In this research, an exemplary study has been conducted in order to draw attention to the importance of evaluating the existing potential on the roofs of buildings. This research offers an evaluation of the existing solar energy and rainwater potential on the total roof area of the buildings in the Izmit district, which is a central district of Kocaeli province, one of the busiest centers of industry in Turkey. The calculations in this study were carried out by using the data obtained from various institutions. As a result of these calculations, the ratio of electrical energy that can be provided with photovoltaic systems on roofs to meet the annual electricity consumption of the district was found to be 203.581%, and the annual solar energy utilization rate for a family of 4 to bring 240 liters of daily use water temperature to 60°C with an 8 m2 collector area was calculated as 66%. In addition, the ratio of rainwater that can be collected from the total roof area of the existing buildings in the district to meet the domestic water consumed by the district was found to be 33.27%.

“…Due to its geographical position, Algeria has a significant potential in solar energy. The average duration of sunshine in Algeria is 2560 hours in coastal areas, 3000 hours in the highlands, and 3500 hours in the desert; this high potential indicates that Algeria has a considerable capacity for solar water heating systems [3].…”

A study with the TRNSYS software of solar water heater installations was simulated for the domestic hot water needs of an average family in the Mediterranean climate of the city of Oran in Algeria. Comparisons of systems with one tank and two tanks have shown similarities in the quantities of energy consumed and captured by the solar panels, but differences have been observed in the coverage of auxiliary energies. On the other hand, the two-tank system makes it possible to produce very significant temperature stratification.
