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.
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) .
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 two types of solar collectors?
Two different types of installations are used: Individual systems for homes or small communities. Photovoltaic panels can power electrical devices, while solar thermal collectors can heat homes or hot water (See Close-Up: “Solar, a Boundless, Universally Accessible Energy Source”).
Which of the following is component of flat plate collector?
A flat collector (Fig 4.14) usually consists of the following components: (i) Glazing, which may be one or more sheets of glass or other diathermanous (radiation transmitting) material(Fig. 4.15). (ii) Tubes, fins or passages for conducting or directing the heat transfer fluid from the inlet to the outlet.
What type of non corrosive material is used for design of flat plate collector?
Absorber plate & Flow passages Copper , which has high conductivity and is corrosion- resistant, is the material for absorber plates, but because copper is expensive, steel is also widely used.
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 does a flat plate collector work?
Flat Plate Solar Collectors. Description: A flat-plate collector is a large, shallow box—typically mounted on a roof—that heats water using the sun’s energy. … Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy.
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.
What is the use of flat plate collector?
The flat plate collector is also considered as a solar thermal energy device used for the applications of space heating, water heating and other many applications.
What is a flat plate collector?
A flat-plate collector (FPC) is a device to collect solar energy and transform it into thermal energy (low-grade energy) by using water as a working fluid. It is a heart of solar thermal devices that has many applications in a medium temperature range ≅100 °C from domestic to preheating to industrial sectors.
What are the main components of a flat plate solar collector?
The collector consists of three major components: an absorber plate, transparent covers, and an insulated box and frame assembly. The absorber plate, commonly a black metal surface, absorbs the incident solar radiation and converts this solar energy to heat.
What is the efficiency of flat plate collector?
The collector efficiency is obtained here, without reflector as 51%, and with reflector as 61%. Thus, the overall efficiency of the flat plate solar collector is increased approximately 10% by using the reflector with the collector.
