The document discusses two main types of solar collectors: flat-plate collectors and focusing plate collectors. Flat-plate collectors are used for low temperature applications below 100 degrees Celsius and consist of a casing, absorber plate, glass covers, insulation, and fluid passage tubes. Focusing plate collectors are used for higher temperatures from 100 to 300 degrees Celsius and concentrate solar radiation onto an absorber tube covered with glass to prevent reradiation losses.

2.  Expose
a
dark
surface
to
solar
radiation so that the
radiation
is
absorbed. This heat
is then transferred to
thermal/heat storage

4. TYPES :1. FLAT PLATE
COLLECTORS : Low temperature
application, <1000c.
2. FOCUSING PLATE
COLLECTOR : For high
temperature, 1000c
- 3000c.

6. FLATE PLATE COLLECTOR
 Consist
of casing, absorber plate,
transparent glass covers, insulating
material and fluid passage tubes.

8. FOCUSING PLATE COLLECTOR

Coming RADIATION on concentrator
is diverted to absorber tube, which is
covered with glass tube to avoid
reradiation loss.
