How much will I save with my solar panels?

Your energy bill is bound to go down. By how much? That depends on your current energy contract, your current energy consumption and the size of your roof. 

But as an example, here's our calculation: 

We consider a standard consumption of 3,500 kWh per year (family with two children). Suppose we can place an installation of 10 solar panels on your roof, the installation will generate around 4,000 kWh of green electricity annually. 

You won't be able to use every kWh of that: for instance, the installation will also generate energy when you're not at home (on a nice summer's day while you're travelling, for instance). On average, you will be able to use about 1,500 kWh of the energy produced. For that energy, you pay us a fixed rate of 0.20 €/kWh (this rate remains unchanged for 30 years, guaranteed!). There will be no more distribution costs, taxes or other charges on top of that. Whereas the electricity you get from the grid cost more than 0.40 €/kWh last year. In this example, you save as much as 50% on that 1,500 kWh coming from the solar panels. That equates to a saving of €300 a year, without any effort or investment.
