- Oliver: you Photovoltaik on the family house, everyone that. But on more family houses there is still huge unused potential and that's where it exciting. Because the numbers are pretty clear. On the roofs of more family houses in Germany alone, to Ariatme analysis, 60 GW of additional PV power could installed. That corresponds to about 28 % of the total expansion demand by 2030. At the time, we the expansion happening, but not where it actually most levers. 2024, 16.2 GW of new PV power were installed. An absolute record, but the majority falls on family homes and free-field facilities, not on classic rental power models. And that's where there's a missed chance. Because a multi-film house has a decisive advantage. The power can really directly on site. You have several parties, you longer usage times over the day and thus a significantly higher self-consumption rate. And it depends on They decide about the economy. The principle, as my colleague Florian in a podcast, used in is much more valuable than the electricity And rental electricity combines exactly that. So cheaper electricity for tenants, additional subsidies for owners and higher independence from energy prices. And that's a very, very big topic The roofing company has also clearly shown that especially in times of higher oil and gas prices, we speed and not slow down. And the energy transition is starting in Germany on the Why does this so little? Because electricity in the practice is a bit complex. Not technically, but structurally. So are measuring concepts, are calculations, are control issues, there are different supply models. And this point many owners simply get because they say, don't I don't understand it, I don't know how it work. But at this point you can course get help. Because there is not only one power supply model, there are several and the models have massive different impact on the economy. So you can classic power supplies, you can consciously feed you can with service providers or simplified models and depending on how you structure it, your returns will significantly. the power supply podcast Florian about 8 to 12 percent, which is definitely doable and here we you to the right concept We don't just at if a performance system is technically possible, but how it is economically optimally. So we analyze the realistic electricity consumption in the house. We look for the right rental power supply supply model for you and also right provider and right insulator who it on your roof. The goal is a model that carries you, in best case even actively invests. And that means lower side costs for the rent, additional income for the owner, a higher attractiveness in the rental and long-term a stable investment and even a valuable investment in your building. important is that photovoltaics is not a replacement for renovation, but a real block. The roofing association says it clearly, for climate goals it both, less energy consumption through renovation and more energy generation on the roofs. Renting power is really one of the unraised levers in existence and the numbers show how big the potential really is. But The difference between PV systems installed and economically useful implemented lies in the model and that is why it worthwhile to the topic strategically and not just technically. I podcast on the subject with Florian in the show notes. you need any time. You can in the show notes.
