Flat-Plate Thermal Collectors
The function of a solar collector is isolation revenue intercept and change in a usable form of energy that can be applied to meet a specific demand.
Flat-plate solar thermal collectors are the most common type solar collector. Its construction and operation are simple. A big plate of blackened material is oriented so that solar energy entering the plate is absorbed and transformed into heat energy as the heating plate. Tubes or conduits are provided to remove heat from the plate, the transfer of liquid or gas, and take him to the charge. One (or more) transparent (glass or plastic) plate is often placed in front of absorbing plate to reduce heat loss to the atmosphere. Similarly, the opaque insulation is placed around the back of the absorber plate for the same purpose. Operating temperature to 125 ยบ C is typical.
Flat plate collector has the advantage of absorbing not only the energy that comes directly from the disk of the sun (normal beam isolation), but the energy solar which has spread in the sky and reflected on the floor. Flat-plate thermal collectors are rarely tracked to follow the daily sun path across the sky, but generally provide a fixed mounting inclination towards the south to minimize the angle between the sun and the surface at noon. Tilt plane collectors south platform, provider of a higher rate of energy in energy and more total midday throughout the day.
Of PV flat plate collectors
Photovoltaic flat plate collectors contain a number of individual photovoltaic cells connected in series / circuit parallel and encapsulated within a sandwich structure with the front surface is glass or plastic. The solar energy falling directly on the front of the cell photovoltaic surface and produces a small voltage direct current electricity supply to a load. Unlike thermal collectors, however, the posterior panel is not isolated. Photovoltaic module need to lose as much as possible the heat to the atmosphere to optimize performance.
As thermal flat plate collector (panels) absorb both energy from direct sunlight, diffuse disc reflects energy from other directions. In general, plates flat panels photovoltaics are mounted in a fixed position and bends south to optimize the daily noon and energy production. However, it is common to see flat plate photovoltaic panels mounted on the mechanisms that track the sun around a tilted axis, thus increasing the production of the panels.
