Uses of Solar Energy

The use of solar energy for space heating of buildings :

The architecturial design of the buildings helps in their passive space heating using solar Energy. Following strategies are useful for passive space heating:

(a) Provide large south-facing windows

(b) Provide an entire wall of double-glazed windows.

(c) Provide a heavy dark-coloured south facing wall behind a layer of glass, with room air circulating by convection between the wall and the glass.

(d) Provide a flat roof covered by a pond of water. Provision should be there for an insulating screen cover for cooling requirement in summer.

Note that no mechanical equipment is needed for passive solar heating.

and electron flow, the two semiconductors act as a cell, creating an electric field at the surface where they meet (known as p-n junction). It is this field that causes the electrons to jump from the semiconductor out toward the surface and make them available for the electrical circuit

Advantages of solar Photovoltaics

(i) Easy installation and maintenance(ii) Pollution free(iii) Long life(iv) Viable for remote and isolated areas, forest, hilly, desert regions.

Disadvantages of solar Photovoltaics:

The high initial cost especially of the silicon wafer is the major constraint in the widespread use of solar cells.
