Solar panel is a unit that saves and uses the energy extracted from sun. a typical solar panel is made up of the combination of different solar cells. As the solar panel is replacement of hydro power unit or wind energy unit; so it’s produced energy is equally useful for all electric or non electric appliances like cars, batteries, TV’s, radio, calculators etc. The increasing amount of hydro panels and their complexity has introduced solar panel (though it’s installation Is also complex) and solar energy and now as the time is passing, every developed and developing country has recognized the importance of installation of solar panels specially in their big cities and industrial areas.
1. Invention of solar panel
The first solar panel was invented in 1954 by the same group of researchers that worked on first telephone i.e. BELL Researchers association.
2. Usage
Solar panels are used to produce solar power which is a great substitute for hydro power and wind power.
3. Complexity
A single solar panel produces only small amount of energy so to produce normal or high level energy few or more solar panels are joined together; Along with an inverter, battery and wires.
4. Cost
The average per watt cost of solar power produced by solar panel is 33 times less than the usual energy or electricity that we use in our daily life.
5. Substitute
In developing countries, solar panels should be installed to make them self sufficient I their energy resources because every year they spend huge amount of their budget on buying or producing power and electricity.
6. Useful for developed countries
Solar panels are installed in developed countries as well, because these countries are usually industrial countries and require heavy energy for mills and industries.
7. Working
Solar panel uses large mirrors and glasses to concentrate sunlight into a point this constant radiation and light beam produces solar power.
8. Leading country
Germany is the leading country in installation of solar power panels. Other countries, following Germany, are United States, Japan and Italy.
9. World’s biggest solar panel
World’s biggest solar panel is in Mojave Desert in North America. It covers 1000 acres of solar reflectors. And it produces 90% of world’s solar power.
10. Future expectations
It is expected that in near future every country where industry exists will install solar panels to produce solar energy. Every country will produce 50% of its energy from solar panel.
