Q What are the functions of the photovoltaic thermal integrated machine (PVT)?
The Photovoltaic Thermal Integrated Machine PVT is an advanced product that utilizes solar energy to supply both photovoltaic power generation and hot water simultaneously.
Q What are the main applications of the PVT system?
The PVT system is mainly used in configurations that require hot water supply, such as hotels, hospitals, school dormitories, nursing homes, high-end residences, swimming pools, agriculture, and animal husbandry.
Q What is the thermal conductive medium of the PVT system?
Usually, the thermal conductive medium of the PVT system is antifreeze, which is mainly composed of alcohol compounds (antifreeze matrix) and corrosion inhibitors (to prevent metal corrosion).
Q Is the investment cost of a PVT system higher than standard solar systems?
While the initial sales price of a PVT is higher than single photovoltaic or single flat plate collector products, its comprehensive solar energy conversion rate is greater than 85%, which is much higher than single PV (~25%) or single flat plate collectors (~50%). By utilizing the same light-receiving area to generate both electricity and hot water, the PVT achieves dual benefits and shortens the investment payback period.
Q What is the conversion efficiency rate of the PVT system?
The comprehensive conversion rate of solar energy for the PVT system is over 80%, providing a highly efficient and energy-saving cogeneration system compared to standard alternatives.
Q How does the structural design support both power and heat production?
The system integrates a power generation part (glass, cover film, solar cells) and a hot water heating part (aluminum alloy heat absorbing plates and pipes), all supported structurally by a secure aluminum alloy frame, chassis, and thermal insulation.
