The solution that fits you best!
The 7 SunnyPower-solar panels you would like to place on your roof have a rated power of 350 Watt. In the Netherlands such a solar panel would yield approximately 300 kWh per year.
Maximum yield = 2100 kWh
(7 solar panels X 300 kWh = 2100 kWh)
Expected yield = 1680 kWh
(2100 kWh X 0,8 = 1680 kWh)
The yield in euro naturally depends on the price of energy. Using a price of 20 cent per kWh (prijspeil bron) this leads to the yearly savings shown here.
Expected savings: €336,-
(1680 kWh X €0.20,- = €336,-)
