Law frame – Licensing procedure
- A new incentives program for small rooftop PV was introduced in Greece on June 4th 2009.
  The new program covers rooftop PV systems up to 10 KWp (both for residential users and small companies) and sets a new feed-in-tariff (FIT) for such systems. The new FIT is 0.55 €/kWh and It is guaranteed for 25 years.
  An annual regression of 5% is foreseen for newcomers as of 2012. No cap is set. The sales contract is signed with the utility (PPC).
- Residential users do not have to be registered as “business” with the tax authorities and are exempted from any tax (with the exception of the 21% VAT paid for the initial investment). Small companies are also exempted from any tax as long as they keep the income from PV as untaxed reserves.
- To be eligible for this FIT, a residence has to cover part of its hot water needs by some other renewable source (e.g. solar thermal).
- Currently, the program is only valid for the mainland grid areas. Islands with autonomous grids will enter the program in a second phase as soon as an extra rooftop solar capacity is set for each island.
- A “small works permit” by the building authorities is the only license needed before installing the system.
Basic Information

Photovoltaic systems on rooftops of dwellings or office buildings are the most direct, practical and financially viable application of solar energy for private individuals and small business.
According to ΚΥΑ of 4/6/2009 «Photovoltaic Systems development on buildings and especially on rooftops», the installation of photovoltaic systems with nominal power less or equal to 10 kW is promoted by a very high feed-in tariff of 0,55 €/kWh.

A private individual or a small business can install from 1 to 10 Kw (maximum needed surface: 150 sqm).

After the accountant counterbalancing with the electrical consumption of the house or the small business, the individual consumer or the small business can profit of an income that can reach even 7.000 €/year (for a photovoltaic system of 10 kWp in Southern Greece).
