Collective self-consumption with photovoltaic system on condominium
Share
Benefits, Regulations and Incentives
Introduction
Solar energy is one of the best solutions to reduce energy costs and improve the sustainability of buildings. Collective self-consumption with a photovoltaic system on a condominium allows residents to share the energy produced, reducing the electricity bill and reducing dependence on the national grid. In this article we will see how it works, what are the advantages and the incentives available.
What is collective self-consumption and how does it work?
Collective self-consumption allows multiple users to share the energy produced by a single photovoltaic system, installed for example on the roof of the condominium. This model is regulated by the legislation on Renewable Energy Communities (CER) and by collective self-consumption groups, introduced to encourage energy sharing between multiple entities.
Here's how it works:
- Installation of the photovoltaic system on the roof of the condominium.
- Connection to the condominium electricity grid with an intelligent energy management system.
- Distribution of energy produced among participating condominiums based on agreed consumption.
- Feeding excess energy into the grid , which is valorised through incentives.
Who can participate in collective self-consumption?
- Apartment owners in the condominium.
- Tenants with owner's consent.
- Condominium administrator for common areas.
Participation is voluntary , so those who do not wish to participate can continue to use their traditional energy supplier.
Advantages of a photovoltaic system on a condominium
Opting for a condominium photovoltaic system with collective self-consumption offers numerous benefits, including:
1. Reduction of energy costs
Each condominium member participating in the project can take advantage of free energy produced by the system, reducing withdrawals from the grid and lowering the bill.
2. Incentives and tax breaks
The Italian State offers various incentives for condominium photovoltaic systems , including:
- Incentive tariff for collective self-consumption (up to €100/MWh for 20 years).
- Tax deductions such as the Renovation Bonus (50%) and, in some cases, the Superbonus.
- Invoice discount or credit transfer to reduce initial costs.
3. Greater energy independence
By producing and using solar energy directly, the condominium becomes less dependent on energy suppliers, protecting itself from fluctuations in electricity prices.
4. Increase in the value of the property
Buildings equipped with photovoltaic systems and collective self-consumption systems increase their energy class , improving their attractiveness on the real estate market.
5. Environmental sustainability
By reducing energy consumption from fossil fuels, the condominium contributes to the reduction of CO₂ emissions and the use of renewable energy.
Legislation and regulations for condominium photovoltaic systems
The installation of a photovoltaic system on a condominium is regulated by Legislative Decree 199/2021 , which implemented the EU Directive on renewable energy, promoting collective self-consumption and energy communities.
Required authorizations
- Condominium meeting : to approve the installation of the system, a simple majority of those present is sufficient (if the cost is borne by those attending).
- Communication to the Municipality : generally a Certified Notification of Commencement of Activity (SCIA) is sufficient.
- Connection to the electricity grid : agreement with the local distributor for the connection point.
Technical requirements
- Maximum power of the system compatible with the condominium network.
- Installing smart meters to monitor energy consumption and distribution.
- Optional storage systems to optimize self-consumption.
How to start a collective self-consumption project in a condominium?
1. Feasibility analysis
The available roof space, solar radiation and the energy needs of the condominium are evaluated.
2. Involvement of condominium owners
The condominium administrator or a group of residents proposes the project and collects the support.
3. Choice of photovoltaic system and supplier
It is essential to select high-efficiency panels and reliable inverters to maximize yield.
4. Request for incentives and authorizations
A specialized technician takes care of the bureaucratic procedures to access the tax benefits.
5. Installation and monitoring
After assembly, the system is connected to the grid and monitored via digital platforms to ensure effective energy distribution.
Conclusion
Collective self-consumption with a photovoltaic system on a condominium is a convenient, sustainable and state-incentivised solution. It allows you to reduce costs on your bill, enhance the value of your property and contribute to the energy transition . With the right information and careful planning, it is possible to transform your condominium into an efficient and autonomous energy community .
