How does a flat plate solar collector work?
WORKING PRINCIPLE OF FLAT PLATE COLLECTORS In FLAT PLATE COLLECTORS Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy.
heat losses to the surroundings are then at a minimum..
What is a flat plate?
The flat plate is a two-way reinforced concrete framing system utilizing a slab of uniform thickness, the simplest of structural shapes. The flat slab is a two-way reinforced structural system that includes either drop panels or column capitals at columns to resist heavier loads and thus permit longer spans.
What are the main components of flat plate solar collector?
The basic components of a flat-plate liquid-heating solar collector include the transparent covers, absorber plate, box and frame assembly, an the sealants.
How many types of flat plate collectors are there?
Flat-plate collectors are basically divided into two categories according to their use, (i) Water or liquid heaters and (ii) Air heaters and (ii) Air heaters. These collectors meant for these uses are sub-divided as follows: The schematic diagram of all these collectors, with single glazing are shown in Fig.
What are the types of solar collectors?
The different types of solar thermal panel collectorsEvacuated tube solar thermal systems. … Flat plate solar thermal systems. … Thermodynamic panels. … Solar thermal air collectors. … Solar thermal bowl collectors. … Domestic Solar Hot Water Systems. … Domestic Solar Water Heating Systems. … Flat Plate Collectors.More items…
What are the advantages and disadvantages of concentrating collector over flat plate collector?
Reflecting surfaces require less material in concentrating collectors than in flat plate collectors. 2. Absorber area is smaller in concentrating collectors. So insulation intensity is greater in concentrating collectors than flat plate collectors.
How efficient are solar collectors?
Based on the calculations from three different sites where Tumba College of Technology installed solar water heaters, we find that the collector efficiencies are in range of 78.5% and 81.7% and tank efficiencies are in range of 71% and 78%.
How do you build a flat plate solar collector?
Here are some easy steps you can follow in building a flat plate solar collector.Step 1 – Test Your Solar Cells. … Step 2 – Cut the Plywood for the Solar Cells. … Step 3 – Varnish the Plywood. … Step 4 – Put Flux on the Solar Cell’s Bus Strips. … Step 5 – Attach the Solar Panel to the Plywood Panel.More items…•
What is the function of solar collector?
Solar collectors transform solar radiation into heat and transfer that heat to a medium (water, solar fluid, or air). Then solar heat can be used for heating water, to heating or cooling systems, or for heating swimming pools.
What are the materials used to make a solar collector?
Raw Materials A passive solar heating system requires a black flat-plate collector panel made of a steel absorber plate covered with two sheets of glass and an insulating pad made of fiber-glass insulation or polyurethane foam with an aluminum foil facing, which acts as a moisture barrier.
What are the 2 main disadvantages of solar energy?
Disadvantages of Solar EnergyCost. The initial cost of purchasing a solar system is fairly high. … Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. … Solar Energy Storage Is Expensive. … Uses a Lot of Space. … Associated with Pollution.
What are the main advantages of flat plate solar collector?
Some advantages of the flat-plate collectors are that they are:Easy to manufacture.Low cost.Collect both beam and diffuse radiation.Permanently fixed (no sophisticated positioning or tracking equipment is required)Little maintenance.
How are solar collectors classified?
Solar collectors can be classified into two general categories: (i) non-concentrating and (ii) concentrating. In the non-concentrating type, the collector area (the area that intercepts the solar radiation) is the same as the absorber area (the area that absorbs the radiation) .
How hot does a solar collector get?
2. Medium-temperature collectors: they concentrate solar radiation supplying useful heat at higher temperature, usually between 100°C and 300°C. 3. High-temperature collectors: temperatures are higher than 500°C, and steam production is possible for power generation.
