Latest / RENEWA Sanierungsnavigator / Neue Studie zu E-Auto und Photovoltaik: Darauf musst du achten
Transcript
- Oliver: you When we about the energy transition, many people directly about heat pumps or insulation. But a topic that often underestimated is your car or rather your e-car. Because what happens when you your car directly with solar power from your own roof? That's exactly what a large study by HTW Berlin has examined with real data from over 700 households and the results are pretty clear. First, average household with PV in system can already a large part of its own car power today. Depending on the size speak of 46 % to 60 % solar energy during the charge. That means, every second drive is done with solar energy. Second, and this is exciting, it is less about the technology, but more about the behavior. If you car when you as well on your phone, then you a lot of potential. With so-called supercharge, that is, charge exactly when the sun is the solar energy increases again. On average, 25 % more. That's a huge lever and it doesn't an additional euro. A third point that many are about is that battery storage is not the game changer that everyone expected, least not when charging Yes, it helps, but on average it a plus of about 9 % more solar content when charging. Why? Well, because cars are often charged anyway, exactly when the sun shines. The exciting part is now. When you PV, storage and e-car, you 73 % energy autonomy in household. This means that you largely independent of the power grid and your electricity bill is decreasing massively. And that is the point that many still underestimate Photovoltaics is not little power, but is your entry into completely new energy system in building. Everything suddenly together. Heating, household electricity, mobility and that's where the real economic lever and also big part of your independence you renovate or about your building, think about your house not without your car, think electricity no longer without your roof and think about energy no longer separated. Because the future is pretty clear, your house is also your gas station.
