Solar panels are gaining interest amongst people of this energy crunched world. What are solar panels? They are an array of photovoltaic cells which capture the energy of the solar rays. In simple terms, the solar panels capture the energy from the sun during the day for later use. Solar energy is renewable source of energy and does not get depleted like coal or natural gas. It can be tapped as much as required and used to power all our energy needs. With the invention of solar panels, which has helped mankind tap the solar energy, solar power has become an increasingly powerful source of energy in the last decade or so.
Solar panels are made of crystalline silicon and gallium arsenide. The same silicon is used in the microprocessor chips. The gallium arsenide is very expensive which also makes the initial investment cost of solar panels high. These panels harvest the solar energy and convert it to electricity. The electricity produced depends on how much of energy is harvested. Roughly, a solar sell of 0.2 m in diameter can create electricity of 2 amps of 2 volts when exposed to direct sunlight at the surface of the equator. However, the electricity production is decided not only by the size of the panel but also by the quality of materials used in making the solar cells. With time as well as with wear and tear, the electricity production capacity of the solar cells comes down.
The solar panels are environment friendly and cause no pollution while producing the electricity. It also causes no imbalance to the eco system. The electricity generated by the solar panels can be used to power a whole lot of appliances. Solar power is very commonly used for lighting needs. Solar panels are also extensively used on satellites. Solar energy is a clean source of power for all needs, having no impact on the environment.
Solar power and solar panels are the energy solution for the future. The conventional sources of energy like fossil fuels and natural gas are fast depleting. To meet the energy demands of the future, we will have to make use of cleaner and renewable sources of energy like solar power. The solar panels relieve you of the dependence on the power grid altogether and can meet all household energy needs.
The smaller solar panels are portable and can accompany you in all your travels. These are very handy when you do not have access to other sources of electricity to power smaller appliances. Hand held devices, laptops, calculators and small motorized vehicles run well with the portable solar panels. There are endless applications for the solar panels if you decide to use them.
Solar panels can be purchased from various solar panel producers and distributors. The price varies and is mainly depending on the power production capacity of the panel. These panels are generally installed in open areas like the roof top or open ground to tap maximum direct sunlight. The location of the panel should be such that it is exposed to maximum sunlight all through the year. Proper selection and installation of a good solar panel will ensure that all your energy needs are met.
The high investment cost of solar panels has dissuaded many people to go in for them. However, the cost alone should not be the deciding factor while selecting a means of electricity. The solar panels produce no toxic gases or products in the generation of electricity and helps keep the environment clean and unpolluted. Using solar panels is the least we can do to protect our environment and make our earth a better place for future generations.
