- Oliver: If we at the current market, we can that photovoltaics are no niche issue. They are now a standard on German roofs. And not only on one-family houses. Florian told me about rental power concepts, which it much easier to install photovoltaics on and them economically. I'll link in the show notes. But to a few numbers. By the end 2020, almost 4.8 million photovoltaic plants were installed Together, these plants have a power of about 106 gigawatts. This is huge amount of electricity and shows how much solar energy has in recent years. In one year, the number of plants has by 17.6 percent, and the installed power has increased by almost 12 percent. On left, one has to say that the growth is still strong, not as dynamic as in previous 2023 and 2024 the growth was still around 27 percent. market is but slowly stabilizes at a new level. important point here, the numbers only to systems that actually electricity into public grid and have a corresponding number. Small power plants are these statistics, which means that reality the expansion is even little higher. An interesting look at the supply chains. and 88 % of the photovoltaic plants that to Germany come from China. The German market is therefore strongly on international suppliers. the time, production of solar modules in Germany has In first three quarters of 2025, more 60 % the modules were produced here in year before. This shows how strong the competition has on the global market. For many owners, photovoltaic not only a building block for more energy independence, but also A small source I think say. Around 4.9 % of private households in Germany now income from the sale of solar power. On average, these incomes were last paid 153 euros per month. However, you a development here. The incomes are lower than a few years This is mainly due to the the food rationing after the EEG has sunk over time And that is why the strategy of many owners In past, was about much electricity as Today, the self-producing so we the self-produced power directly in household. This is, frankly, also the sustainable strategy. Especially in connection with heat pumps, electromobility or energy refining, Photovoltaic is becoming more more the central building block in the energy system of a building. An interesting comparison also to the size of Photovoltaic. With around 106 GW of power, Photovoltaic has actually the largest installed power plant in all energy forms in Germany. For comparison, wind energy on land is at 63 gigawatt installed power, offshore wind energy at around 9 gigawatts, gas power plants at 32 gigawatts and coal power plants at total 40 gigawatts. This means that purely from the installed power is now largest power plant park in Germany, could say. However, installed power not automatically that a lot of electricity is Because photovoltaics only electricity when the sun shines. That's why you at an energy system also after the so-called full-load hours. Photovoltaics on average to about 900 to 1000 full-load hours per year. Wind energy on land is about 2000 hours. Offshore wind at 4000 hours. Coal power plants, sometimes over 6000 hours. This means that a coal power plant produces significantly more electricity than in such a system as long as are no supply chains in But let's just out there. That's the actual power production is distributed So if a photovoltaic current currently at around 60 to 56 terawatt hours per year, wind energy at over 130 terawatt hours. Nevertheless, the photovoltaic current is for the energy system, especially because it can centrally on buildings. And that's why it in energy restoration. The modernized automatically thinks about photovoltaics, often combined with heat pump, storage or charging infrastructure. And who wants to whether photovoltaics on his roof or whether a storage makes I'll the podcast on topic of power storage in heart. I'll it in the show notes And of course, also free to contact We are always happy
