The Sun

I am a young renewable energy broadcaster in South Africa, I have light skin with strawberry blond hair which brings out my bright beautiful eyes. My character is very diverse, so I may keep you interested.
I could not help but start writing about what my company, Solarstar believes in, We forecast a wealth of knowledge in Solar Power, we install grid-tie, stand alone and hybrid solar power systems for neighbors. Solar Water Heating is another option we install. We attract awareness and harvest free energy to people like you who have made a decision to be here and now start contributing to the green revolution. Thanks!

6 billion years ago, the Sun, a very big nuclear reaction that makes its own mass into light particles called photons. Tons and tons of these photons are all around us in the Earth's atmosphere. Every second. Life relies on this energy. At sea level on a clear day, 1 kWh of sun-light falls on 1 square meter area. That's enough power to run most of our appliances in our houses

Imagine snakes squirming frantically across a hot road. Their entire bodies wriggle and wriggle in such a way that the motion pulses them forward. You can picture a photon in the exact same way, except much faster. Photons are always moving at the speed of LIGHT.
An important aspect of a photon is its wavelength, which is just what it sounds like. In this case of the snake, the wavelength is the distance between two successive peaks in its wriggling motion. Larger snakes have longer wavelenths and vise versa. Larger snakes also wriggle much slower than the smaller ones, and this is called the frequency.
Wave length is important for solar systems because the physical components that make up a solar system respond differently to different wavelengths. E.g the sun produces far more infra-red radiation than visible radiation, but we don't see the infra-red at all. In some solar applications, It's the infra-red that is most important; in other applications we may be interested in visible light.
When you focus your eye sight on a object, you see the light that has reflected off that object. So when you see a green plant, the plant has absorbed all the wavelengths besides green. When we see white, you're seeing all colours at the same time. A white object generally doesn't absorb any colours of light - it reflects them. A black object, however, absorbs everything. This property is very useful for solar projects for the fact it absorbs as much sunlight as possible.
Why is the sky blue?
Each photon has different energy, and you see different colours because your eyes react to different differences in energy. Red photons have less energy than blue, and infrared photons have much less than ultraviolet. So basically, a clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
