Development and Field Testing of a Novel Hybrid PV-Thermal Solar Collector
Abstract
This paper presents laboratory and field data of the new Virtu hybrid PV-thermal solar collector developed by Naked Energy Ltd. By mounting PV cells on a novel phase-change thermo-syphon heat plate contained within an evacuated tube, Virtu can deliver hot water in the temperature range that is required for domestic hot water and space heating, whilst providing simultaneous electrical power. Laboratory tests show excellent performance at high output temperatures, and field data collected in Malta show that 40-60°C hot water can be delivered all year round. A transmissive low-emissivity coating has been developed and tested leading to further enhancement of the thermal performance.
