PV or solar energy panels are very useful. Also known as photovoltaic panels, PV panels are constructed from semi-conductor materials. Silicon is a great example of a semi-conductor material. The reason why this material is used is because it can gather a huge amount of electrons. It’s the photovoltaic effect that causes photovoltaic cells to generate electricity.
When sunlight hits these cells, solar radiation occurs, which generates electricity. These systems offer several advantages. PV panels generate renewable energy, and a PV panel also has a very long lifespan. A lot of people choose PV panels Read the rest of this entry »

Answering the question of whether solar energy will put the electric companies out of business is necessarily a two-part answer. First, one needs to look at whether this is possible in the current market. Second, one should look to what the future of the market holds. This is because these two answers are different.
Currently, the answer is no. For solar energy to seriously challenge the electric companies, solar power would need to be a cheaper Read the rest of this entry »

Out of all of the existing renewable energy sources on the planet, sunlight is easily the top source. Sunlight happens to be the only renewable energy source that is capable of keeping up with humanity’s insatiable appetite for electricity.
Over the span of a single hour, an enormous amount of sunlight hits the earth. It would take a full year supply of fossil fuels to equal the amount of energy sunlight produces in one hour. However, the biggest Read the rest of this entry »

Humankind has been harnessing the sun’s power since ancient times using a glass lens, similar to a modern magnifying glass, to concentrate the sun’s rays to light fires. Horace de Saussure, a Swiss naturalist, is believed to be the first person to collect the sun’s energy with his invention of a solar-powered oven in 1767. His design, an insulated box coated with layers of glass, could reach temperatures of 230 degrees.
A half-century later, French scientist Read the rest of this entry »

PV panels function by converting the rays of the sun directly into usable electrical power, without any of the pollution or waste products that conventional energy production may result in. The ability to generate cheap, abundant and clean energy in a wide range of environments, and with little need for conventional infrastructure, makes solar power a versatile and valuable source of renewable energy. Investing in solar panels and installations to provide some, or even all, of the power you need for your Read the rest of this entry »
