What Is a PV-T (Photovoltaic Thermal)? Plain-English Guide (2026)
Definition: Hybrid solar panels that generate both electricity and heat simultaneously
PV-T (Photovoltaic Thermal) Explained
PV-T (Photovoltaic Thermal) panels combine solar PV cells with a solar thermal collector in a single unit. They generate electricity like standard solar panels while simultaneously capturing heat from the sun to warm water for your heating system.
How Does a PV-T (Photovoltaic Thermal) Work?
- Sunlight hits the PV-T panel surface
- PV cells generate electricity from photons
- A fluid circulating beneath the cells absorbs remaining heat
- Warm fluid heats your hot water cylinder or supplements heating
Pros and Cons of a PV-T (Photovoltaic Thermal)
| Pros | Cons |
|---|---|
| Generates electricity and heat from one panel | Higher cost per panel than standard solar PV |
| More energy per square metre than PV alone | More complex plumbing and installation |
| Cooling the PV cells improves electrical efficiency | Fewer UK installers experienced with PV-T |
| Ideal where roof space is limited | Limited product range compared to standard PV panels |
