A Flat plate Photovoltaic (PV) module that only contains flat solar panels is known as a flat-plate photovoltaic system. Flat-plate arrays as well as modules utilize both direct and diffuse sunlight, however, if the array is set in place, part of the strong sunlight is wasted due to the sun’s oblique angles concerning the array.

The most popular type of solar array design using flat-plate solar modules as well as panels is a flat-plate photovoltaic module. Either these panels can be set in situ, or they can follow the path of the sun. Direct or diffuse sunlight affects how they behave. Even in a clear sky, approximately 10% and 20% of the entire solar energy that strikes a horizontal surface is made up of diffuse sunlight. About 50% of that energy is dispersed on days with partial sun. Also, all the energy is diffused during cloudy days.

How does a Flat Plate Collector Work?

A flat plate collector (FPC) relies on thermal energy transfer to operate. The working medium of the Flat plate Photovoltaic (PV) exchanges the energy from the sun’s rays. The collector’s heat-absorbing plate takes in direct sunlight. Some of the energy from the sun’s beams is converted into heat as it strikes the flat plate surface. The flat-plate solar collector’s temperature increases as a result. As a fluid passes through a collector, its temperature rises as a result of the heat being transmitted to the fluid from the absorption plate.

At the end of the Flat plate Photovoltaic (PV), the fluid moves the thermal energy from the collectors to the functional energy systems for a variety of uses. The initial and 2nd thermodynamic principles apply to how it works.

What are the Components of a Flat Plate Collector?

The typical parts of a collector with a flat plate collector are as follows:

1. Absorbing Plate: This part of the collector’s interior captures solar light. Solar energy is transformed into heat energy by the absorbing plate. In most cases, it pertains to a dark plate composed of copper foil.

2. Tubes or Passages: A grid of conduits is present on the absorbing plate of a flat plate collector. They are tubes or channels that allow the fluid that transfers heat to circulate. It helps with the working fluid’s conductivity from the input to the outlet.

3. Insulation and a glazing cover: It minimizes heat loss from the absorbent plate. It may be found on the plate collector’s sides and rear. Synthetic foam sheets are commonly used as insulation (fiberglass, polyurethane, etc.)

4. Shell or Container: The casings serve as the flat-plate solar collector’s closure or resting surface. All of the components are held in place by this aluminum structure.
