Previous energy law in Italy

As regards the energy production from solar photovoltaic source, it has been possible to benefit from government incentives provided by GSE S.p.A. in “Feed-in Tariff (FIT) scheme” (the so-called Conto Energia). The FIT for photovoltaic system stops 30 days after reaching an indicative yearly cumulative cost and this limit was reached on 6th June 2013, determining the cessation to require incentives to GSE, except for those which are enrolled in the register for big-sized plants and entered into balance sheet within one year. From now on, the PV sector is expected to work without FIT, by taking advantages of fiscal benefits, regulatory framework and new market opportunities dealing with self-consumption systems.

New policy framework

The new Italian “Stability Law” 2014 introduces important news to foster fiscal benefits for interventions, concerning energy efficiency retrofit and building heritage recovery. This Act extended the eco-bonus from 36% to 50% for energy improvement and anti-seismic retrofit interventions in 2014 and up to 40% until 31st December 2015 for building renovations. So, it is possible to deduct on IRPEF (income tax of natural person) a portion of expenses incurred to renovate houses and common area in residential building in Italy. With the Resolution no. 22/E of 2nd April 2013, Italian Revenue Authority set out that this tax deduction has to be applied also to installation of solar photovoltaic systems, as an alternative to the policy in “FIT” and taking into consideration the legislative framework, as follows:

  • 50% tax deduction, recoverable in 10 years on the cost of implementation’s plant;
  • energy savings, indicated in the bill (in the last few years, the average cost is increased by 67%);
  • the opportunity to benefit from the net metering conventions on the site or GSE simplified purchase e resale rearrangements, which may be accumulated with tax deduction.

The implementation of a photovoltaic system is still profitable, for example a plant for domestic use, equipped with own consumption (3-6 kW) and 20 years working life, will offer a payback period not longer than 8 years.


When existing building are retrofitting with solar thermal systems, the integration of solar thermal components into existing systems must be made as easy as possible. In fact, we can use solar thermal energy for domestic or industrial water heating and above all it is completely renewable sources produced directly by sunlight. Solar thermal systems combine space heating and produce domestic hot water (DHW). The integration of solar thermal into conventional heating systems is important, because it allows to ensure good conditions for the performance.

A solar water heating system can be also used to heat a swimming pool during the summer and it can provide a large amount of the heating demand. The low solar energy density makes possible the use of hot water at not so high temperature (between 40°C and 80°C), suitable for DHW and for space heating, which benefits from low-temperature systems, radiant-floor heating system and wall heaters (up to 60°C).

For the installation, it is recommended to take into consideration the following factors:

  • south-facing rooftop availability;
  • high grade solar collector (40°C-90°C);
  • low temperature of heating and plumbing loop
  • radiant-floor heating system and wall heaters
  • buildings with good thermal insulation.

The heat distribution system can supply both domestic hot water and space heating. The heat transfer unit are used to control the space heating loop flow, return temperature and supplies heat by using a heat exchanger, which transfers heat from one fluid (heated collector fluid) to another (stored water) and it goes in a storage tank (boiler) to be used as needed.

Until December 2013, it was decided to adopt two different ways in the tax deduction field for the installation of solar thermal collectors, as follows:


The Ministerial Decree of 28th December 2012 the so-called Renewable Energy for Heating & Cooling Support Scheme” (Conto Termico) introduced financial incentives for the implementation of solar thermal systems and other interventions to improve energy efficiency and to promote thermal energy from renewable sources. This support scheme involves public administration entities and private subjects, such individuals, household, businesses and agriculture enterprises and it provides the following tax deductions:

  • incentives on capital costs up to 40% on the eligible investments, recoverable in 2 years, depending on type of implementation, scale and technology;
  • incentives are open for private entities, individual condominium and public administrations;
  • as regards thermal solar and solar cooling technology, the incentive is calculated per installed square meter: 170€/m2 up to 50 m2 surface and 55€/m2 for installations with a surface area greater than 50m2; as concerns the solar cooling systems, the incentive rises at 255€/m2 and 83€/m2.


With the approval of the Decree Law no.63/2013,it has been scheduled an extension of the existing tax deduction system for retrofitting works, which went from 55% to 65% and it is possible to benefit from 6th June 2013. These measures can be applied on new solar panels installation for domestic and industrial hot water production and to fulfill the needs of hot water in swimming pools, sport facilities, nursing homes, schools and universities.

The maximum threshold for this deduction is 60.000€, recoverable in 10 years.
