Photovoltaic-thermal (PV-T) technology generates electricity and captures solar heat in one module, maximizing the energy harvested from every square metre of roof. Across the European Union, adoption is growing steadily from a still-small base, which leaves substantial headroom as binding renewables targets create exactly the conditions PV-T is built for. From our vantage point selling into these markets, the direction of travel is clear — the open question is pace.
What is driving PV-T growth in Europe?
The updated Renewable Energy Directive (RED III) sets a legal target of 42.5% renewables in EU energy consumption by 2030. Because the directive covers heating and cooling as well as electricity, dual-output PV-T is doubly relevant. Technology helps too: module efficiency keeps improving, and producing electricity and heat from a single footprint answers the space constraints of urban buildings and district energy systems.
What still holds the market back?
Three barriers dominate. Upfront costs are higher than for a plain PV or solar thermal array of the same area, the price of getting both electricity and heat from one roof, which can deter smaller projects. Awareness among developers, installers and end users is limited. And certification for dual-output products is still less standardized than for established solar thermal schemes such as Solar Keymark, so a manufacturer's testing record and years of field experience are the practical benchmark when comparing products. Add the need for trained installers and compatible thermal storage, and the industry's to-do list is clear: standardization, workforce training and proactive outreach. Collaborative programmes — the IEA Solar Heating and Cooling Programme's Task 60 (2018–2020) and EU-funded innovation projects — have built performance benchmarks and are developing reliable business models.
Which policies and funds support PV-T?
| Market | Key instrument | What it does | | --- | --- | --- | | EU-wide | RED III, Horizon Europe, Innovation Fund, EIB loans | Binding targets plus R&D grants and low-interest financing | | Germany | Renewable Energy Sources Act (EEG) | Feed-in support and incentives for hybrid solar | | France | Multiannual Energy Plan (PPE) | Sets national solar and renewable-heat targets; heat projects are funded via the ADEME Fonds Chaleur | | Italy | Conto Termico | Direct incentives for onsite renewable heat | | Netherlands | SDE++ | Operating support behind record PV-T installations |
Simplified permitting, net-metering rules and community funding models under RED III further empower decentralized projects, from urban rooftop retrofits to district heating schemes. Some local jurisdictions even mandate renewable installations in new building projects.
Where does the market stand today?
Germany, the Netherlands and France lead, combining policy support with active industry players. The Netherlands has posted record PV-T installations on the back of favorable grants and building codes. Manufacturers such as Solimpeks, which has built PV-T collectors since 2008, supply modules for multi-family housing, commercial buildings and district energy solutions. Energy cooperatives in Germany and Denmark pool purchasing power to widen access and strengthen local energy resilience. Given how small the installed base still is, that activity signals substantial headroom rather than saturation.
What scenarios shape the next decade?
Expect the strongest growth where PV-T is paired with heat pumps or district heating — pilot projects integrating PV-T with heat pumps and smart energy management already show significantly improved system efficiencies. Bifacial cells and better heat exchanger designs keep raising yield per square metre. On the business side, energy-as-a-service, community solar-plus-thermal grids and district heating integration reduce upfront capital barriers, while digital monitoring and AI-driven optimization position PV-T within smart, integrated energy systems.
For a sustainable market, the roles are complementary: policymakers harmonize rules and keep incentives technology-neutral; manufacturers push efficiency, transparency and third-party certification; communities run pilots and spread ownership through cooperatives. With those pieces in place, PV-T moves from promising niche to standard component of Europe's clean energy transition.
