An integrated photovoltaic-thermal (PVT) combined heat and power equipment, independently developed by CSCEC, has recently been put into operation. As an integrated unit designed for the energy needs of temporary site facilities, the product couples photovoltaic power generation, solar thermal utilization and dual-source heat pump technology, offering a replicable and quantifiable low-carbon energy solution for projects under construction.

The equipment adopts a PVT plus dual-source heat pump design. Through modular integration, it simultaneously delivers green electricity, heat collection and hot water supply. It can be rapidly deployed in office and living areas of temporary site facilities, adapting well to typical construction scenarios with concentrated personnel and fluctuating energy demand.

At the ESWIN Wuhan silicon materials base project, the energy system requires only a 100-square-meter PVT array with an installed capacity of 21.6 kilowatts. It supplies 10 tons of domestic hot water daily, meeting the daily needs of about 300 people, generates about 21,600 kilowatt-hours of green electricity annually, and cuts carbon emissions by about 30 tons per year.

At the civil and environmental innovation building project of Huazhong University of Science and Technology, the equipment is integrated with a PVT carport, making use of the space above the office-area parking lot. It can supply up to 10 tons of hot water per day, generate about 13,000 kilowatt-hours of green electricity annually, and cut carbon emissions by about 20 tons per year.
