  • The researchers from Finland tested the system in different modes and found that the hybrid mode, which combines solar and heat pump operation, resulted in higher and faster drying rates than the solar-only mode.
  • The experimental system that uses solar thermal energy and a heat pump to dry woody biomass. The system consists of two containers, one with a heat pump and solar collectors, and another with a drying chamber. They also suggested that photovoltaics (PV) could play a complementary role in powering the heat pump and reducing grid dependence.
