Hydraulic solar container charging pile

Can energy piles store solar thermal energy underground?

Ma and Wang proposed using energy piles to store solar thermal energy underground in summer, which can be retrieved later to meet the heat demands in winter, as schematically illustrated in Fig. 1. A mathematical model of the coupled energy pile-solar collector system was developed, and a parametric study was carried out.

What is a coupled energy pile-solar collector system?

For a coupled energy pile-solar collector system in practical engineering, the solar collectors will be mounted on the exterior walls and roofs of buildings to minimise additional land use. To avoid oversizing the solar collector area, it is important to maximise the efficiency of the solar collector through optimal design.

How does a solar energy pile-soil system work?

The heat-carrying fluid particle transports heat from the solar collector to the energy pile-soil system continuously. The rate of charging and discharging depends on the flowrate, the intensity of radiation, and the condition of the energy pile-soil system.

What is a solarcontainer?

The Solarcontainer is a photovoltaic power plant that was specially developed as a mobile power generator with collapsible PV modules as a mobile solar system, a grid-independent solution represents. Solar panels lay flat on the ground. This position ensures maximum energy harvest Panels lays flat on the ground.

What are energy piles?

One is the primary geotechnical function, and the other is a heat exchanger. Compared to other energy geo-structures, energy piles have been most-widely investigated and adopted in practical engineering to replace the traditional boreholes of the GSHP systems , , .

What is the maximum temperature of a solar energy pile?

It indicates that both the inlet and outlet temperature of the energy pile undergo a rapid increase during the first hour. Then they increase quite slowly as the underground storage of solar thermal energy continues. The maximum inlet temperature is about 60 °C.
