You are not entitled to funding?
Even if you're not eligible for subsidies, purchasing a balcony power plant is usually worthwhile. Depending on the module, you can save several hundred euros in electricity costs per year. This means the balcony power plant pays for itself.
You'll usually recoup the initial investment in 3-6 years. With a 20-25-year performance guarantee, balcony power plants offer enormous savings potential. At the same time, you'll become less dependent on the power grid by producing your own green electricity.
