A single customer and a single primary cabin
The integrated widespread self -consumption (Tiad) text provides for three different configurations that can access the incentives for self -consumption: in addition to the best known ones, Cer and groups, there is also the individual self -consumer “remotely”.
Technically it is a configuration that provides at least two distinct connection points: one connected to a consumer user and one to which a production system is connected, which must be found in a different area but within the same primary cabin. In addition, both the (consumption) and entry (production) withdrawal points must be registered to the same subject.
Considering that on average in the city a primary cabin can cover up to four neighborhoods, and in rural centers up to four municipalities, this means that there are many possibilities to take advantage of the economic advantages offered by this system in specific situations, that is to say:
- When it is not possible to install the system at the service of your home, but you have another property on which you can install and on which there is a consumption user;
- When you have other consumption users and you can install the panel in the house.
The important thing is that the system is placed at the service of multiple users, because only in this way is the maximum advantage.
Direct and virtual consumption with a single system
In essence, with this configuration for direct self -consumption, full savings are obtained in the bill (28 C €/kWh) for the energy consumed, while for the “shared” energy virtually the GSE incentive rate (10.4 C €/kWh) is obtained plus the Arera contribution (0.8 C €/Kwh).
The calculation mechanism by the GSE is the same for all configurations, for which the incentive rate is recognized on the overall share of consumption recorded at the same time by all the withdrawal points present in the configuration with respect to the hourly production of the system.
Thus, for example, placed a production of 100 and a consumption of 70, the incentive will be on 70, while the excess quota can be sold through the dedicated retreat system. Clearly higher the consumption in the time slot of the production of the panels is the higher the gain, but it is still possible to install storage batteries and in this case also the energy stored and used in the hours in which the panel does not produce contributes to the calculation of self -consumption.
Let’s see some practical examples to better understand the savings and earnings.
Savings and earnings: Case 1
Maria, professional with office and home: installing a 6 kWp “medium” photovoltaic system at the office, where there is an air -conditioning air conditioning and heating system, and configures the self -consumer at a distance for the house, not being able to install the system at home because there is no space on the condominium terrace.
Office bill (where there is the panel):
- Annual consumption: 4,000 kWh
- Direct self -consumption: 3,200 kWh
- Bullet saving: 3,200 kWh × 28 C € = € 896
- Residual network consumption: 800 kWh = € 224
- Final Office bill: € 224 (instead of € 1,120)
House bill (virtual consumption):
- Annual consumption: 3,500 kWh
- Shared energy: 2,900 kWh
- Incentive received: 2,900 kWh × 11 C € = € 319
- Residual consumption from network: 600 kWh = € 168
- House final bill: € 168 (but receives € 319 of incentive)
Result:
- Office bill: -€ 896 (from € 1,120 to € 224)
- House bill: +€ 319 of incentive – € 168 = € 151 of net profit
- Total annual advantage: € 1,047
Savings and earnings: Case 2
Mario, merchant with shop and home: install a 6 kWp system on the house roof and configure the self -consumer at a distance for the shop.
House bill (where there is the panel):
- Annual consumption: 3,000 kWh
- Direct self -consumption: 2,400 kWh (evening/weekend)
- Bullet saving: 2,400 kWh × 28 C € = € 672
- Residual consumption from network: 600 kWh = € 168
- House final bill: € 168 (instead of € 840)
Shop bill (virtual consumption):
- Annual consumption: 5,200 kWh (lights, climate, fridge always on)
- Shared energy: 3,600 kWh
- Incentive received: 3,600 kWh × 11 C € = € 396
- Residual network consumption: 1,600 kWh = € 448
- Final bill shop: € 448 (but receives € 396 of incentive)
Result:
- House bill: -€ 672 (from € 840 to € 168)
- Shop bill: +€ 396 of incentive – € 448 = € 52 of net cost
- Total annual advantage: € 1.120
Other hypotheses
But you can also hypothesize, for example, the case of a panel at the service of a house of home and a holiday home by the same owner, or also other configurations, for example the panel on the car garage located in another condominium, but which is used to recharge the car, and so on.
On balance, by connecting multiple users you have a return of investments in much faster times, considering that if the panel is installed on a property for living use there is the 50% deduction if first home, or 36%. The tax deduction can be totally combined with the rate incentivized. Furthermore, Arera’s rate and contribution are not subject to taxation.
Request
Applications can be submitted online, on the GSE website. For these incentives, there is no expiry date at the moment.
