“…Although solar irradiation on the horizontal surface was at its maximum in June and July, the most advantageous month for output power was August due to the average monthly sunshine duration During the operation of the system, the excess of energy was 1833 kWh/year, which represented 31.66% of the total PV production. The excess energy could be harnessed either in the charging station by adding storage batteries for EV charging, in the maintenance of the charging station, or for other types of applications [41], such as lighting, charging electronic devices, agricultural activities, electricity supply for irrigation, and greenhouses [42], which generate additional costs, either by injecting electricity into the grid network if possible.…”

“…For the sunniest day in August, sun irradiation was available between 6:00 a.m. and 9:00 p.m., with maximum values between 12:00 p.m. and 3:00 p.m.-the period during which photovoltaic panels generate power for the direct supply of the EV consumer, as well as for storage in batteries in order to meet the energy demands of the charging station for times with low availability of solar irradiation, such as cloudy days and at night. Additionally, the energy excess on this day could be harnessed by injection into the public electricity distribution network if there is a connection to it, used in other types of applications [41][42][43]; or be used in isolated areas that do not have access to the grid.…”

Since mid 2010, petrol consumption in the transport sector has increased at a higher rate than in other sectors. The transport sector generates 35% of the total CO2 emissions. In this context, strategies have been adopted to use clean energy, with electromobility being the main directive. This paper examines the possibility of charging electric vehicle batteries with clean energy using solar autochthonous renewable resources. An isolated system was designed, dimensioned, and simulated in operation for a charging station for electric vehicles with photovoltaic panels and batteries as their main components. The optimal configuration of the photovoltaic system was complete with improved Hybrid Optimization by Genetic Algorithms (iHOGA) software version 2.4 and we simulated its operation. The solar energy system has to be designed to ensure that the charging station always has enough electricity to supply several electric vehicles throughout all 24 h of the day. The main results were related to the energy, environmental, and economic performance achieved by the system during one year of operation.

“…By 2040, an increase of around 40% (based on the current fleet) of the electricity requirement is expected. This increase by 7200 gigawatts may substitute the existing energy generators [5,29]. The strongest growth of renewables in many countries raises their share worldwide power generation, to one third by 2040 [15,30].…”

Nowadays, the evolution of solar energy use has turned into a profound issue because of the implications of many points of view, such as technical, social, economic and environmental that impose major constraints for policy-makers in optimizing solar energy alternatives. The topographical constraints regarding the availability of inexhaustible solar energy is driving field development and highlights the need for increasingly more complex solar power systems. The solar energy is an inexhaustible source of CO2 emission-free energy at a global level. Solar thermal technologies may produce electric power when they are associated with thermal energy storage, and this may be used as a disposable source of limitless energy. Furthermore, it can also be used in industrial processes. Using these high-tech systems in a large area of practice emboldens progress at the performance level. This work compiles the latest literature in order to provide a timely review of the evolution and worldwide implementation of Concentrated Solar Power—CSP—mechanization. The objective of this analysis is to provide thematic documentation as a basis for approaching the concept of a polygeneration solar system and the implementation possibilities. It also aims to highlight the role of the CSP in the current and future world energy system.

In the global context of energy transition from fossil fuels to renewable sources of energy, solar energy plays a key role in electricity generation, having the highest annual growth in the last years. This case study focuses on improving the overall energy efficiency of a household through thermal retrofitting, harnessing solar energy with photovoltaic (PV) systems and using air-source (ASHP) or ground-source (GSHP) heat pumps. The electricity generated by the PV systems is used to power the heat pumps and all other electricals of the household. The simulations for the ASHP and GSHP systems were conducted with GeoT*SOL software, while for electricity generation by PV systems, PV*SOL Premium software was used. The comparative results show: a decrease in the heating load to about 51.56%; an annual heating requirement of 53.88% of the normed one; an energy consumption index of about 58.34 kWh/m2·year; an annual energy consumption reduction of 88% for ASHP and 91% for GSHP, compared with the current gas heating system; 34% of the household consumption was covered by the PV system in the case of using ASHP and 36% for GSHP; and lower operating costs by 47% for the PV system with ASHP and 53% for the PV system with GSHP.
