The global energy crisis has convinced all governments to invest more in the use of renewable and sustainable energy sources. To achieve this goal, solar energy is more attractive due to its accessibility in most parts of the earth. Photovoltaic (PV) modules are used to convert sunlight into electricity. This technology has an important drawback, as the increase in PV cell temperature significantly reduces its electrical efficiency. This article provides a solution to overcome this issue to some extent. In this regard, the effects of using both porous media and wind stream are evaluated, experimentally. Three different thicknesses of aluminum porous medium 0.5, 2 and 4 cm are investigated with and without wind blowing at 2 km/h. The results indicate that the proposed cases pull down the module temperature between 3.9 ̊C to 18.3 ̊C. From energy point of view, when the 4 cm porous medium is used, 2.7% and 6.6% enhancement are attained in electrical efficiency and output power, respectively. The second law of thermodynamics was also applied and the maximum drop of 8.3% in entropy generation was calculated. The last part of this paper reports an overall comparison of the present results with those of other similar experimental papers.

“…The above effect may be important, as summer in central Europe has become hotter over the past decade. It should be noted that there are a lot of technologies that are available in energy markets to increase the efficiency of a PV panel, for instance [43][44][45][46]. These technologies are mainly based on cooling PV panels through the use of heat sinks or water cooling.…”

The presented paper shows a hypothetical large solar farm that would be the only source of electricity for the entire country. The energy crisis in Europe raises the question of whether it is possible to supply an electrical system based only on renewable energy sources. What should the surface area of the solar panels be in a hypothetical large solar farm to power the entire country? In this work, we will show what requirements must be met to make this feasible. Very important differences between the installed power capacity in a coal-fired or nuclear power plant and a solar power plant are discussed. The article presents calculations of the surface area of photovoltaic panels in that solar farm for four exemplary countries in Central Europe: Poland, Germany, the Czech Republic and the Slovak Republic. These studies are particularly important for Poland, whose electrical system is still mainly based on coal-fired power plants. The hypothetical solar farm could, in practice, take the form of dozens of solar power plants located in different parts of the country. Most importantly, the proposed solution will counteract climate change.

“…However, they did not focus on the power consumption. Agyekum et al (2021) [9] investigated the effect of a combination of active and passive cooling mechanisms for the solar PV module. They combined aluminum fins, water, and ultrasonic humidifier to cool solar PV panels under real weather conditions.…”

“…Nevertheless, they did not compare the actual data to the simulation data. Furthermore, PraveenKumar et al (2021) [12] conducted an experiment effectively for the passive Regarding renewable energy for hardware and mechanism improvement, Agyekum et al (2021) experimentally investigated actual solar power generation [8][9][10] and emulated the wave energy [11]. Agyekum et al (2021) [8] aimed to be a lower temperature of the solar photovoltaics (PV) through double-sided water cooling to increase power generation efficiency.…”

In recent years, environmental and energy issues relating to global warming have become more serious, and there is a need to shift from conventional power generation, which emits an abundance of carbon dioxide, to renewable energy sources without emissions, such as solar and wind. However, solar power generation, which is one of the renewable energies, changes dynamically, depending on real time weather conditions. Thus, power supplied mainly by solar power generation is often unstable, and an appropriate on-demand energy management for demand-to-supply is required to ensure a stable power supply. Demand-to-supply management methods include inventory management analysis and on-demand inventory management analysis. The cumulative-control method has been used as one of the production management methods to visually manage inventory status in factories and warehouses, while the on-demand cumulative-control method is an extension of inventory management analysis. This study models a demand-to-supply management method for a solar power generation system by using the on-demand cumulative-control method in an actual case. First, a demand-to-supply management method is modeled by an on-demand cumulative-control method, using actual power data from a childcare facility in Tokyo. Next, the on-demand cumulative-control method is adopted to the case without batteries, and the amount of electricity to be purchased is estimated. Finally, the effectiveness of the maximum battery capacity and the amount of the initial charge are examined and discussed by sensitivity analysis.
