Solar panels-renewable electricity or heating for your home

The Sun is not only the source of light, but also a source of energy. Plants use this energy of the Sun by a process known as photosynthesis. This energy is then stored in terms of biomass. Something similar to this is the technique used in the case of solar panels. This is a newly developed apparatus for producing solar energy from sunlight. There are mainly two ways that solar panels can help you in your home or Office-photovoltaic and water heating systems. The article further elaborates on these two.

Photo voltaic Panel module or

A photovoltaic module or Panel is composed of a number of inter-connected photovoltaic cells, also commonly called solar cells. These solar cells are placed on the Panel in the form of a wafer. These wafers are manufactured by a thin film of a very commonly used semiconductor, Silicon. Silicon has a special property of being extremely sensitive to sunlight. Then captures the energy carried by photons and then converts it into electricity. This energy is then stored in solar cells for future use. Diodes are also included in this type of solar panel to avoid overheating of the photovoltaic cells.

Solar panels have a higher initial cost, but require little maintenance except that need to be well protected by strong mechanical shocks as they are extremely fragile and delicate.

SOLAR THERMAL COLLECTORS

As the name suggests, these types of solar panels are used to collect heat from the Sun. This heat can then be used to heat water to produce water solar hated or can be used to boil water into steam which is in turn used to move the turbines and generate electricity. There are many types, but most commonly used are solar thermal collectors, flat-screen TVs as water heating systems.

This type consists of a flat sheet black well protected and isolated an element absorbent. In this paper are black absorber tubes which are hollow to carry water. When the Sun's rays hit the black sheet Panel and the pipes absorb heat and water flowing via simple convection. This solar-heated water then can be used for many purposes in homes or offices. Solar heating systems are widely used in many colder regions of the world.

Although thermal collectors are efficient in providing high temperature results may vary in the days of diffuse light that is cloudy.
