System Research in Energy| Summary: | Amid the energy crisis in Ukraine and the instability of centralized energy supply, the strategic importance of developing decentralized renewable energy sources is growing. Increasing attention is being paid to hybrid autonomous energy systems, particularly the combination of heat pumps and photovoltaic-thermal (PVT) panels. This integration enables comprehensive coverage of household heat and electricity demands while reducing dependence on gas and centralized grids. The aim of this article is to review modern design solutions of PVT systems, their operating principles, advantages, and challenges in integration with heat pumps. The paper substantiates the role of such systems in enhancing energy efficiency and energy autonomy of private households in Ukraine. A photovoltaic-thermal (PVT) collector combines a solar thermal collector and a photovoltaic module in a single unit, simultaneously generating heat and electricity. These collectors can serve as a heat source for brine-water heat pumps, increasing the seasonal performance factor (SPF) and reducing the need for deep drilling of ground heat exchangers. The article examines various configurations of PVT and heat pump integration (series and parallel circuits, uncovered and covered collectors) and optimal thermal-to-electric capacity ratios adapted to Ukrainian conditions. System modeling demonstrated competitive performance of hybrid configurations: for example, a PVT-HP system with a finned collector can achieve SPF ≈ 3.5–3.8 (for 20–30 m² of panels) and SPF(Grid) up to ~4.4. Combining PVT with a geothermal source further increases efficiency (SPF > 4.0) with reduced borehole depth (~70 m), and under drilling constraints helps reduce the area of horizontal heat exchangers while improving overall system performance. Based on the analysis of recent international and domestic studies, the article provides an analytical summary to assess the feasibility and prospects of implementing combined PVT-HP systems in Ukraine's residential sector. |
