What is PV-T?

Twice the output from the same roof space

A conventional solar PV panel converts around 20% of sunlight into electricity. The remaining 80% is lost as heat. A PV-T hybrid panel captures some of this otherwise wasted heat energy via a fluid circuit, delivering it for use in space heating or hot water.

The result is a single panel that simultaneously generates electricity and useful thermal energy: the highest-yield solar technology available for buildings with both electricity and thermal demand.

PV-T is a specialist product, though, and not right for every building. It only pays off where the heat has somewhere useful to go and demand for it stays high throughout the year: buildings with only occasional or seasonal heat demand are usually better served by standard PV alone.

  • ✓Higher combined efficiency: electricity and heat from the same roof area
  • ✓Perfect for heat pump integration: warm fluid boosts heat pump COP
  • ✓Reduces heat pump electricity demand for lower running costs
  • ✓Multi-manufacturer range: flat-plate and evacuated-tube formats
  • ✓Full system design service: mechanical and electrical integration

Our differentiator

Our directors have helped shape many of the PV-T products on the market today: co-developing early panels and securing the first PV-T system to achieve MCS accreditation in the UK. We've been designing and installing PV-T systems since the earliest days of the technology, and that depth of experience is exactly why we know when it's the right call for a project, and when it isn't.

System comparison

PV-T vs standard solar PV

Standard Solar PV

  • ✓Generates electricity only
  • ✓~20% solar conversion efficiency
  • ✓Surplus electricity exported at SEG rate
  • ✓No thermal benefit

Solar PV + Heat Pump

  • ✓Electricity from PV powers heat pump
  • ✓Two separate system installations
  • ✓Good combination, needs larger roof area
  • ✓High performance when well-designed

FAQs

PV-T hybrid: your questions answered

What is a PV-T hybrid panel?

A PV-T (photovoltaic-thermal) panel generates electricity and captures heat from the same roof area. A thermal absorber behind the solar cells extracts warmth that would otherwise be wasted, cooling the cells, which improves their electrical output, while delivering hot water or space heating.

Which businesses benefit most from PV-T?

Any organisation with year-round demand for both electricity and hot water: leisure centres and pools, care homes, hotels, food production facilities and process industries. If you currently pay to heat water and to power the building, PV-T addresses both from a single installation.

Is PV-T more efficient than separate solar PV and solar thermal?

Per square metre of roof, yes: a PV-T array can achieve combined efficiencies of 60-80% versus around 20% for PV alone. Where roof space is constrained, it is the highest-yield option available. Where space is plentiful, we model both approaches and recommend whichever delivers the better return.

How is a PV-T system maintained?

The electrical side needs the same minimal attention as standard solar PV. The thermal circuit is a sealed system similar to solar thermal, and an inspection of fluid condition and pressure as part of an annual service keeps it performing. Remote monitoring covers both outputs.
