  • Less roof space required than equivalent system comprised of a separate Solar PV and Solar thermal systems.
  • Hybrid PV-T system’s ROI (Return On Investment) is shorter than standard PV systems due to higher electrical yield and off-set heating costs.
  • Lifetime of PV cells is lengthened because cell operating temperature is reduced.
