A thermal cell panel system for heating and cooling using a refrigerant includes a plurality of solar thermal cell chambers, and a piping network for a flow of the refrigerant through the plurality of solar thermal cell chambers. In addition, the system includes a compressor having a motor coupled to a variable frequency drive (“VFD”), where the compressor is coupled to the piping network upstream of the plurality of solar thermal cell chambers and the VFD is configured to adjust a speed of the motor in response to the pressure of the refrigerant within the plurality of solar thermal cell chambers. The piping network includes an inlet manifold coupled to the inlet of each solar thermal cell chamber, and an outlet manifold coupled to the outlet of each solar cell chamber.

A digital fluid heating system may include a solar collection system configured for focusing sunlight on a focal axis, an elongated flow element arranged and configured for transporting fluid along the solar collection system at the focal axis, and a flow-control assembly comprising a digitally controlled valve configured to control the flow of the fluid in the elongated flow element such that pathogens present in the fluid are substantially inactivated before the fluid exits the fluid heating system and at a maximized flow rate under the given energy providing conditions. The system may also include one or more digital controls and communication systems for remote and/or automatic control.

A solar energy roof tile, thermally and/or electrically conductively connected to an adjacent solar energy roof tile, includes a lower face for placing on at least some regions of a roof construction, an upper face opposite the lower face formed at least in some regions by a solar energy utilisation module, two opposite lateral walls, a rear face connecting the lateral walls, and a front face opposite the rear face that connects the lateral walls.
