Saving with solar power: the advantages of new PV systems reveal!

The increasing popularity of photovoltaic systems (PV systems) is supported by a new video series from Krone Sonne under the title "You knew that ...". This series, which deals with the advantages of PV systems, is devoted to the question of how users can save money by using solar energy. In the second video, the longevity of modern PV systems is discussed, which can achieve impressive durability of up to 30 years or more. The investment in solar technology is described as sensible because it quickly pays off and enables long -term cost savings, which is also clearly shown in the videos. Further details about the video series are on crown to find.

Looking globally, the energy requirement grows steadily and solar energy is taking an ever increasing proportion of covering this need. According to a report by DW The electricity generation is currently mainly divided into coal power with 35% and gas with 22%. The proportion of solar power, on the other hand, has grown in recent years and rose from 1% in 2015 to 6% in 2023. In 2023, new photovoltaic systems with a total output of 447 gigawatts (GW) were installed, which resulted in an increase in global solar power generation by 38% to 1624 GW.

Growing influence of solar energy

The forecast development of solar energy is promising. It is expected that 20% more solar systems are being installed annually and that the globally installed solar power could reach around 5117 GW by 2028. The drastic decline in module prices over the past 15 years, which has been promoted by mass production in China, has led to the cost of solar power reduced by over 80%. In sunny regions, solar power can now be obtained for amounts between 3.5 and 5.4 Eurocent per kWh.

The spread of photovoltaics is not only limited to Europe. Countries such as China, Australia, Japan and India have established remarkable capacities. China alone covers 10% of its electricity requirements with a national solar power limit of 656 GW, followed by Australia with 36 GW (15% of the needs) and Japan with 90 GW (12% of the needs). Brazil, the USA and Mexico, also draw attention to themselves with their own capacities in the solar sector.

Historical development of solar energy

The use of solar energy has a long history. Even early cultures worshiped the sun and used it in architecture and technology. The path from the first experimental solar module by Charles Fritts in 1883 to modern PV systems was marked by numerous developments. The 1970s brought renewed interest in solar energy, fueled by the oil crisis and the growing need for alternative energy sources. Today's renewable energies, which also include solar energy, are not only a technological but also a historical achievement, as shown Solar system guide is described in detail.

The combined view of these developments shows that photovoltaics not only become a decisive factor in global energy supply, but can also make a significant contribution to reducing CO2 emissions and thus to achieve the goals of the Paris climate agreement. This positive development could be crucial for the future energy supply in the world.
