What is “super ammortamento”?

Every year, the Budget Law decides on tax breaks for the adoption of advanced tangible and intangible assets. These include, until 2020, the ‘super ammortamento’ for a photovoltaic system.

“Super ammortamento” consisted of the possibility to increase the cost of an Industry 4.0 capital asset, incentivising its purchase. If a company decided to install a photovoltaic system on the roof of its factory, the deduction guaranteed a depreciation coefficient of 130% on the expenditure.

Thus, paying 100, it was possible to deduct up to 130%

The conditions for access were that:

  • having paid 20% of the expenditure by 31 December 2019
  • have spent a maximum of EUR 2.5 million
  • be a business owner or natural person carrying out activities under the advantageous regime
  • purchase goods sold by third parties/contracted goods/contracted goods

The Budget Law of 2021, however, transformed this super depreciation for photovoltaic systems, introducing the tax credit in its place, setting it at 6%

  • the tax credit will be valid until 31 December 2022 for assets not belonging to Industry 4.0
  • for tangible and intangible assets that are part of Industry 4.0, on the other hand, such as photovoltaic systems, the former super depreciation has been confirmed until 2025, with a progressive reduction in the percentage of the credit

Further incentives for 2022

Reverse charge

Reverse charge regime whereby the acquiring company is exempt from paying VAT immediately. Therefore, the burden shifts to the supplier.
This is an incentive created to cut down on tax evasion and can be claimed in the case of the installation of photovoltaic systems:

  • integrated
  • semi-integrated
  • ground-based

The seller will not have to issue an invoice, but the company will have to issue a self-invoice to be entered in the income and expenditure registers.

Nuova Sabatini
Already in place during 2020, revised and renewed. The Budget Law 2021 envisaged that this financing scheme dedicated to SMEs would be simplified.

Under the previous rule, the financing was divided into six instalments, with the exception of loans of up to EUR 200,000, which were paid in full; in 2021, however, the option of paying in full was extended to any amount between EUR 20,000 and EUR 4 million, with a duration of no more than five years of financing.

This remains unchanged for 2022 as well.

Decree FER1
Indirect incentive, as opposed to former depreciation, for the installation of photovoltaic systems in companies. It is still in force even in 2022, but is changing shape: in fact, a new RES1 Decree and also a RES2 Decree may come into force in the coming months.

This facilitation concerns installations with a capacity ranging from 20 kW to 1 MW. A fee is received from the calculation of the amount of clean energy fed back into the grid.

Only companies that adopt new photovoltaic systems to replace the asbestos or eternit that previously covered their company buildings can benefit from the RES Decree1.

Exchange on the spot

This mechanism, which is not new, allows you to sell back to the Gestore dei Servizi Energetici (GSE) and feed back into the grid the energy your panels produce extra, i.e. the excess electricity you do not need to support your business’ energy needs.

Following reinjection, you will be entitled to a balance that will appear on your electricity bill.


Ça va sans dire, moreover, that with high utility bills, the investment in a corporate photovoltaic system can pay for itself in no time, even without incentives.
