Renewable Energy Communities 2026: incentives, operation and materials needed to implement them (Technical Guide for Installers and EPCs)

Renewable Energy Communities 2026: incentives, operation and materials needed to implement them (Technical Guide for Installers and EPCs)

Summary

2026 is a key year for Renewable Energy Communities (REC) and photovoltaic systems with storage in Italy.

With the regulatory framework now stabilised and the GSE’s 20-year incentives fully operational, a significant acceleration of projects in residential, industrial and agricultural contexts is expected.

For installers, EPCs, construction companies and designers, this means a substantial increase in demand for systems and the need to rely on reliable, certified and immediately available supplies of materials.

In this guide, we analyse:

  1. how CERs work
  2. what incentives are available in 2026
  3. What materials are needed to produce them?
  4. What opportunities are available for professionals in the sector?
  5. how to optimise procurement to reduce costs and delays

What are Renewable Energy Communities?

CERs are configurations in which multiple entities — citizens, businesses, public administrations — share energy produced locally by renewable energy plants, mainly photovoltaic.


Production and sharing take place within the same primary substation, as required by GSE regulations.

Typical CER technologies
  1. residential and industrial photovoltaic plants
  2. modular or containerised storage systems (BESS)
  3. hybrid inverters with smart sharing management
  4. digital platforms and smart meters

Incentives active in 2026 (CER / CACER Decree)

2026 represents one of the first years of full operation of the CER incentives.

Incentive tariff on sharing
  1. duration: 20 years
  2. applied to each kWh shared between CER members
  3. can be combined with self-consumption and other local benefits

Other economic advantages
  1. valorisation of energy fed into the grid
  2. significant reduction in energy bills
  3. possibility of scaling the system with new storage units
  4. greater energy resilience

Why 2026 will be the year of the CER boom

1) Regulations finally consolidated

The GSE’s operating rules have established a stable framework after years of waiting.

2) EU push towards 2030 targets (PNIEC)

CERs are a central part of the new National Energy and Climate Plan.

3) Fall in the cost of PV modules and batteries

Compared to 2023–2024, prices are more competitive.

4) More stable grid geared towards distributed generation

Thanks to investments by Terna and local DSOs.

Materials needed to create a CER (technical version + B2B)

An efficient Energy Community requires quality supplies and certified components.

1. Professional photovoltaic modules

  1. High-efficiency TOPCon

  2. bifacial modules for ground-mounted or agrivoltaic systems

  3. panels with a 25–30-year warranty

2. Hybrid inverters and string inverters

  1. Integrated PV + storage management

  2. remote monitoring

  3. sharing optimisation algorithms

3. Storage systems (BESS)

  1. Modular LFP batteries

  2. BESS containers for industrial sites

  3. scalable systems from 10 kWh to MW

4. Mounting structures

  1. sloped and flat roofs

  2. structures for agrivoltaics

  3. solutions with single-axis trackers

5. BOS components

  1. DC/AC electrical panels

  2. certified cables and protections

  3. smart meters and supervision systems

👉 Procurement is crucial for installers and EPCs: delivery times, certifications and compatibility determine the success of the project.

Who can participate in a CER in 2026?

  1. households
  2. SMEs and industrial companies
  3. public administrations and municipalities
  4. condominiums
  5. agricultural companies
  6. third sector organisations

How to create a CER: operational steps

  1. Technical-economic analysis
  2. System design and sharing modelling
  3. PV installation + storage + switchboards
  4. Smart meter configuration
  5. Registration with the GSE
  6. Activation of the twenty-year incentive

👉 Procurement enters phases 2 and 3, when certified and immediately available components are required.

Conclusions

2026 will be a decisive year for the spread of Energy Communities.

Installers, EPCs and designers will have to manage strong growth in demand and ensure efficient, scalable and compliant systems.

To do this, they need reliable suppliers, tested materials and immediate availability. Are you planning photovoltaic installations or CER projects for 2026? Request a dedicated quote now for modules, inverters, storage systems and BOS components.
