1. Recreational .

Solar energy is a renewable energy source, unlike fossil fuels (non-renewable energy sources) such as coal, oil, gas, which according to recent data can be restored, but at a very low rate, that in the future they will not be enough to power the entire population of the planet.

2. Inexhaustibility
   Solar energy is inexhaustible, it cannot be produced too much, and it will always be enough for absolutely all the needs of mankind for many more generations to come.
3. Quantity of energy
   The amount of energy from the sun reaches the earth annually about 1 billion terawatt-hours, while the mankind produces about 20 thousand terawatt-hours per year, i.e. 0.002% of the sun’s energy that reaches the earth.
4. Silent
   Quietness of solar energy systems is achieved due to the fact that there are no moving parts, such as in a large capacity wind turbine with a rotor.
5. Large area of application
   Solar energy is something that can be used for remote regions of any country where there is no centralized power supply. This energy can be used as a heating element, as auxiliary equipment to increase the production of fresh water in remote communities in Egypt, and of course it is one of the main sources of energy for the International Space Station (ISS) and satellites, since in space the power of solar radiation is much higher than on the surface of the Earth.
6. Economy of operation
   By using solar panels as an alternative energy source, owners of buildings and private homes will achieve great savings. The decisive factor in maintenance is that the maintenance costs are very low. Solar panels only need to be cleaned a few times a year to maintain them, while the manufacturer’s warranty starts at 10 years.
7. Ubiquity
   Solar energy goes where the sun shines, which means absolutely all parts of the planet, both at the equator and in northern latitudes, making it possible to produce solar energy everywhere.
8. Ecology
   Ecology, one of the most acute problems in the modern world. Humanity is fighting the environmental problem with all its might, but the predominant use of non-renewable fuels leads to extensive pollution, a huge amount of waste is stored in vast areas, which has already had a detrimental effect on nature and human health. Whereas solar energy is the most environmentally friendly energy, since the installation of solar panels and all associated equipment releases virtually no harmful substances into the environment.
9. Advanced Technologies
   Solar power does not stand still. Each year there are new developments with better materials, increasing the efficiency of the solar panel, allowing solar panels to take up less space and produce more energy. Modern developments in solar panel technology will increase the efficiency in the foreseeable future to 50%.
