- yardie 2y agoDid I imagine that Russia invaded Ukraine in 2022. And then the price of energy in Germany shot through the roof as Russia stopped exporting. The electrical needs of most homes is fairly fixed. The price of that electricity can change at any time. So why 1000€ and not 5000€.
- f1shy 2y agoAfter the initial invasion prices went up, now going down again. Also Germany has extremely expensive electric energy.
- Freestyler_3 2y agofor 1000 euro electricity 25k solar system?? You should not come above 1,5€ per Wp of solar. so for a 4500wp system, 6750€ and that is a high price and will provide more energy than consumed.
- f1shy 2y agoYes. Should is the key word. As the government pushes lots of people to install solar, prices soar… also my house is particularly bad for solar (roof parts looking exactly west-east) so I install double of what will be used.
