Techno-economic analysis of a hybrid photovoltaic-thermal solar-assisted heat pump system for domestic hot water and power generation

This work investigates the techno-economic performance of a hybrid photovoltaic-thermal (PVT) solar-assisted heat-pump system for covering electrical and hot-water demands three-bedroom terraced house in Belfast, United Kingdom with four occupants. combines water-to-water heat pump PVT panels to deliver both electricity hot water domestic consumption. The array provides source low-temperature pump, while cooling thus preventing efficiency degradation that occurs at higher operating temperatures. Analyses have been performed arrays different size, including 12-panel, 20-panel 24-panel systems. Results show that, thanks its lower initial investment cost, most economically viable configuration household considered this is based on 12-panel total area 16.3 m2. has potential produce 2.4 MWh (gross) 2.0 per year, which equivalent just over 30% 80% under consideration, acting reduce consumption heating by little 60%. recurring yearly costs relative current energy systems use from grid natural gas, despite having costs. It also found can investigated household's annual CO2 emissions 910 kg year (about 18 tonnes lifetime 20 years) an generation incentive rate 5 p/kWh 21 p/kWh, aforementioned discounted payback period 14 years.
