The price of petrol and electricity continues to surge just as our supply of coal, wood, oil and fossil fuels rapidly dwindle. We have to explore other sources of energy and search for more economical and environmentally-friendly alternatives. Our best bet is to turn towards the renewable power sources such as wind, water, geothermal, biogas and of course, the sun.

The sun provides us with two sources of energy – heat, or solar thermal energy, and electricity, or photovoltaics. By harnessing the sun’s rays, our reliance on fossil fuels could be virtually eliminated. As energy prices hike and the threat of global warming looms over our heads, it is high time that we turn our attention to the sun. Contrary to traditional notions, new advancements in technology have made solar energy powerful and more reliable. In fact, many homes, industries and businesses across America are completely or partially powered with solar energy.

But just how do you convert the sun’s rays into solar electricity? The technology is actually quite simple. Thin sheets of silicone crystals are encased in a durable yet lightweight contraption known as a solar panel. Photons from sunlight then cause the electrons in the panel to stir and move, thus creating a higher state of energy which is then converted into electric power. This electricity is then carried through a circuit to make your house’s lights light up and appliances function. Since these panels are made of tempered glass that have the strength of auto glass and skylights, they have a very long lifespan. Since solar panels do not have any moving parts, they are very durable and last a very long time. Even though they entail quite a substantial initial cash outlay, solar panels can definitely shave dollars off your electricity bill in the long run.
