Should you not know just what solar panels are, solar panels are a collection of several solar cells and although each one of them provides a small amount of power these solar cells can spread over a very large area which can also provide just enough power so to be useful. For you to get the most power that you can the solar panels must be directly pointed to the sun.

The spacecrafts are mostly designed with this solar panels which can be pointed right at the sun with the entire body of the spacecraft while aimed independently. Then there is a tracking mechanism which often is incorporated right into the solar arrays which shall keep the array pointed right towards the sun.

These panels do need some surface areas as more exposure will mean more electricity which shall be converted right from the light energy. Many satellites do purposely orient some solar panels right out of a direct alignment within the suns path.

So if the electricity which is needed, is lower than all of the amount of electricity that is made, then the extra power that is needed shall be then vented by s shunt right into space where it will then dispel some heat. The solar panels are known to be compared to any alternative power sources. The solar panels are known to wear out slowly while in space.

There is a principle factor that affects the loss of power and that is the solar radiation. The low earth orbiting satellites do have their effectiveness lowered by 1 to 2 percent each year. And a higher radiation environment shall be able to cause the solar arrays to lose almost half of their power, all within 1 year.

There is the photovoltaic concentrator solar arrays too, which are used primarily for some spacecraft power and they use lenses known as Fresnel lenses which take a big area of the sunlight and will direct it right to a certain spot just by bending the rays of the light and then focusing them. This is the same principle as when you use a magnifying lens and focus the rays of the sun onto a piece of paper and start a fire. The solar concentrator can put these type of lenses right over each solar cell.
