Investing in solar panels on roof tops

The Regional Development Ministry?s Photovoltaic System Development Program provides for any individuals installing a system of up to 10 kilowatts on their roof to be able to sell the energy produced to the Public Power Corporation at a price of 0.55 euros per kilowatt/hour.

Given that a 10-kW system has an average output of 13,600 kWh per year, the annual income from selling the energy produced to PPC would amount to 7,480 euros, with a one-off investment up to 30,000 euros that is 100 percent covered by banks.

The price of 0.55 euros/kWh is fixed for the next 25 years, taking potential total revenues to 190,000 euros.
