You probably have been thinking of investing your money in solar equipment, or just liked the sound of generating power for your home without the need of having a power company supply you electricity and you thought knowing more about how it works would be great. This article will break on what solar energy is and how it really works.
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaic, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. For instance, technologies such as Photovoltaic (PV) are used to capture the light from the sun and covert it to electricity. The power is conveyed through wires to an inverter that will in turn, change the Direct Currents (DC) to Alternating Currents (AC). The electricity will be stored in batteries finally. Solar panels work by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise mainly of units called photovoltaic cells. Photovoltaic simply means they convert sunlight into electricity.
Energy from the sun is readily accessible. Equipment like the solar panels can be placed in locations where the light rays from the sun are direct and without obstruction. Solar panels can be placed on the roof of buildings, angled towards the sun.
Fossil fuels like coal; oil and natural gas supply 80 percent of the world’s energy to light homes, charge devices and power transportation. Energy has always been one of the world’s biggest puzzles. Still unsolved, there have been technologies built by great inventors far back into the 20th century that proposed solutions to the ‘big need’ for power. These technologies have ended-up causing more damage than the good they were made to do.
The world needs energy, not just any kind, but clean energy. That which we will not have to trade something precious for it, not even the air we breathe. It’s all about the eco-system, something safe. Going green would affect our lives for the better.
