Residential panels for heat collection are referred to as flat plate solar collectors. Solar collectors are special kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium.
The schematic of a flat plate solar collector with liquid transport medium is given here. The black absorber plate absorbs radiant heat from sunlight. due to convection and radiation to the atmosphere. There are tubes carrying water, which gets heated due to the heat absorbed. The thermal insulation prevents heat loss during heat transfer.
In residential systems, simple and cheap solar panels are used to collect the solar heat energy below 60°C. Residential panels for heat collection are referred to as flat plate collectors. Solar energy collectors are special kind of heat exchangers that transform solar radiation energy into internal energy of the transport medium.
The plate is usually made of copper, steel, or plastic. The surface is covered with a black material of high absorptance. A selective coating can be used to maximize the absorptance of solar energy and minimizes the radiation emitted by plate. The flow passages carry the working fluid through the collector.
Flat plate collectors are the most common type. They are also referred to as non concentrating collectors and have the same area for intercepting and for absorbing solar radiation. A typical flat plate collector is an insulated metal box with a glass or plastic cover (called the glazing) and a dark-coloured absorber plate.
Home / Technical Articles / How solar collectors works? Solar energy (solar radiation) is collected by the solar collector’s absorber plates. Selective coatings are often applied to the absorber plates to improve the overall collection efficiency. A thermal fluid absorbs the energy collected.

The flat-plate solar collectors are probably the most fundamental and most studied technology for solar-powered domestic hot water systems. Principle: The basic principle for this device is that the sun heats a dark flat surface, which collects as much energy as possible, and then the energy is transferred to water, air, or other fluid for further use. Construction and Working: These are the ...
9. Flate Plate Collector Flat Plate Collectors -consist of a thin metal box with insulated sides and back, a glass or plastic cover (the glazing) and a dark colour absorber. The glazing allows most of the solar energy into the box whilst preventing the escape of much of the heat gained. The absorber plate is in the box painted with a selective dark colour coating, …
A flat plate solar collector simply converts radiant solar energy from the sun into heat energy, which is then used to heat water. However, while simple in design and operation, there are several components that make these collectors operate desirably and several essential equations that are used for designing them.
