This invention relates to flat plate solar collectors and, particularly, to solar panels applied in these flat plate solar collectors.

The proposed solar panel is designed as a shallow box, with rear and front walls, which are conditionally vertically positioned a most part of the external surface of the front wall is provided with a coating absorbing solar radiation.

In addition, the internal side of the rear wall is joined with an auxiliary perforated sheet.

There is a rectangular pipe, which is installed vertically or horizontally on the exterior side of the front wall and serves for passage of a liquid to be heated.

The solar panel is functioning as a flat heat pipe with zones of evaporation and condensation on the front wall.

Elastic deformations of the front and rear walls under difference between atmospheric and internal pressure allows to prevent overheating of liquid in the vertical rectangular pipe.

Photovoltaic thermal (PVT) apparatus 10 combines a photovoltaic panel (PV) panel 24 and solar air heater (SAH). The SAH includes body 12 with hollow interior 14 defining ducts 16a, 18a for air inlet 16 and air return 18. Jets 22 provide air to convey heat from the PV panel underside. Spaces between the jets provide drains 26 for warmed air to flow away. Flow modifiers/deflectors 124 can guide the airflow. A fan 42 pushes ambient air into the inlet 16 via air handling unit (AHU) 50. Return warm air flows via the AHU to escape via the ambient exhaust 40. A combined thermal transfer and storage unit 52 determines whether air from the PVT panel(s) diverts to the interior space. For cooler ambient conditions, the PVT apparatus can radiate heat to return cooled air into the space. The PVT apparatus can harvest condensation, heat/cool pools and industrial processes.
