The main aspects of charging electric cars from solar panels have been studied, namely from solar panels that have a rotating axis behind the sun, this allows for an increase in energy storage by 20-40%.

Various technologies and systems for charging electric vehicles from solar panels are considered, including rooftop solar panels, mobile charging stations and other innovative solutions. The environmental benefits of using solar panels to charge electric vehicles are highlighted, including reducing CO2 emissions and dependence on oil. The economic benefits are analyzed that pivot-axis solar panels have the potential to collect more solar energy because they are always aimed at the sun. While static panels standing still can lose some of their potential energy due to improper alignment. The financial benefits associated with the reduction of fuel and electricity costs, as well as the possibility of generating additional income through the sale of excess solar energy to the grid, were discussed.

The technical challenges related to the efficiency of solar panels, charging capacity and energy storage are considered, as well as the directions of development of these technologies are predicted.

The results of research into the process of charging an electric car from solar panels  are described. It is shown that the best solar panels have an average efficiency of 20.5%, considering the number of sunny days in Ukraine, this is enough to use energy to charge a car. It has been established that for an average driver who drives about 15,000 kilometers per year, which is even higher than the average, to cover charging needs, about 2,700 kW is needed, which is about UAH 11,000 per year, which is very cheap for a car owner.
