100% Transition 5.0: 4 Steps for Installers in April
📅 April 2026
⏱ Reading time: 7 minutes
On April 1, the government restored the Transition 5.0 funds to 1.5 billion euros: up to 100% credit on high-efficiency panels, with the “Made in Europe” requirement removed. On March 30, the GSE published the operational rules for 1.9 billion euros in PNRR funds for agrivoltaics and energy communities. Your industrial clients who locked in their quotes in March are waiting for your call.

What you will find in this article
- How does 100% financing work, and which products qualify for it?
- GSE deadlines for agrivoltaics and CACER to mark on your calendar this week
- Which products should you choose to streamline documentation and close the deal?
- The business strategy to win back customers who have been inactive since March
The background: Three weeks of gridlock, and then a turning point
By the end of March, Decree Law 38/2026 had cut Transition 5.0 funding from 1.3 billion to 537 million, reducing the tax credit to 35%. Dozens of negotiations had stalled. Industrial customers were waiting, installers had quotes sitting in drawers with no response.
On April 1, 2026, following discussions at the MIMIT table between Minister Urso and Confindustria, the government reversed course: funding rose to 1.5 billion (the original 1.3 billion plus an additional 200 million). The credit returns to 100% for high-efficiency photovoltaic panels and to 90% for capital goods that reduce consumption. The “Made in Europe” requirement has been eliminated. (source: ANSA)
At the same time, on March 30, the GSE published the Operating Rules for the 2026 PNRR Facilities: 1.1 billion for agrivoltaic development and 795.5 million for Energy Communities and self-consumption groups (CACER). Two separate calls for proposals, closely spaced deadlines, significant funding. (PV Magazine Italia)
⚠️ Operational Note
The agreement reached on April 1 is a political one and has not yet become law. It will be formalized upon the conversion of Decree Law 38/2026, which is expected within the first ten days of May 2026. Do not make any definitive promises to customers before the Official Gazette is published, but start preparing your offers now: timing is key.
1. 100% Financing: Who Qualifies and What It Takes to Get It
The Transition 5.0 tax credit does not go to the installer: it goes to the company or SME that purchases and installs the system. Your competitive advantage lies in your ability to help the customer qualify for the credit, with the right products and all the necessary documentation in order. This is where your purchasing strategy for Tier 1 modules: proposing the wrong products means losing the application, not just the deal.
To qualify for the maximum credit, the system must meet three conditions:
- Use of high-efficiency photovoltaic modules (a criterion that will be specified in the conversion law)
- Certified reduction in energy consumption of the production unit
- Technical documentation certifying the efficiency and performance of the installed system
The “Made in Europe” requirement has been removed: this significantly expands the range of eligible Tier 1 products, including major Asian manufacturers. For those working with direct imports from China, this is structurally significant news for purchasing strategy.
2. GSE deadlines: Agrivoltaico and CACER are being decided now
📊 Key Dates — Agrivoltaics and CACER
For agrivoltaics, the GSE rules require integrated planning between agricultural and energy production: simply installing panels on farmland is not enough. Crop monitoring systems, documentation on maintained agricultural yields, and verifiable performance metrics are required. Those developing these projects must act now, not wait until summer.
For CACERs, the funding mechanism is defined, but competition for funds will be fierce. Those arriving with a structured project and an established technical partner have a head start. Learn more about the latest news on QualEnergia.
The GSE webinar on April 9 (10:00 a.m.) will cover the PNRR operational rules and the MPRIN mechanism—compensation for lost production from non-programmable renewables, now extended to all plants. Register if you manage PNRR projects.

Specifically, for Transition 5.0, the LONGi Hi-MO X10 modules and the AIKO ABC series exceed 24% efficiency with certified back-contact technology — a level of technical documentation that simplifies the application process and strengthens the customer proposition. The HPBC 2.0 technology has obtained EN 13501-1 Class “B-s1, d0” certification, which is increasingly in demand in industrial and agrivoltaic contexts.
For agrivoltaics and CACER, the choice of inverter and storage is equally critical. In a PNRR project, reporting to the GSE requires certified production data over time. Growatt — with the WIT 50 BESS (capacity exceeding 1 MWh, scalable for C&I applications) integrated into the cloud monitoring platform — generates exportable energy reports that directly meet the requirements for verifying the contribution. In a CACER project where you must demonstrate energy sharing among members, a documentable metering system is not optional.
4. Business opportunities: Who to call this week
- Customers with quotes on hold since March. They’ve put their decision on hold while waiting for regulatory clarity. Now they have it. A direct message—“funding has been fully restored; we can reopen the quote”—is highly likely to elicit a response right now.
- Agricultural businesses with available land. The June 30 deadline for GSE agreements on agrivoltaics creates a real, not artificial, sense of urgency. Those who are first to submit a technically sound project have a structural advantage in accessing funds.
- Industrial companies with high energy consumption. With 100% credit on panels (subject to legislative confirmation), the payback calculation for a C&I system changes significantly. Revisit pending quotes with the updated figures.
The PVclick solution: a short supply chain, the right products, and well-organized documentation
To take full advantage of these incentives, the product cannot be separated from the purchasing strategy. A high-efficiency panel purchased through three or four intermediaries comes at a cost that squeezes margins and reduces the competitiveness of your offer.
With PVclick, you shorten the supply chain and purchase directly from Tier 1 manufacturers — LONGi, AIKO, Jinko, Trina, Canadian Solar and others — with support from the Italian team at every stage of the import process. Same product, lower cost, data sheets, and certifications directly from the manufacturer for the Transition 5.0 program.
