SOLAR PANELS

The solar panel is a set of solar cells. Although each solar cell produces relatively little energy, a large number of solar cells, distributed over large areas, can produce enough energy to be useful. To maximize the effectiveness of solar panels required to send directly to the sun.

 

      Spacecraft are usually equipped with solar panels, constantly aimed at the sun regardless of the rest of the body. To the battery had been sent only to the sun and equip their vehicle tracking sunlight.
      For solar cell requires a lot of space more than it, the more electricity can be obtained from the energy of light. But if you produce more energy than you need, you have to dissipate excess energy in the space in the form of heat.
      Solar panels are almost impossible to compare with other energy sources. In space, they wear out very slowly. The main factor influencing the loss of the ability to accumulate energy is solar radiation. The effectiveness of low-Earth orbit is reduced by 1-2 per cent per annum. If the solar panels will be placed in the environment with higher levels of radiation (in the middle of orbit), they could lose half the power for one year.
      Solar panels photovoltaic concentrator, used as the primary power source for space vehicles, includes a lens called Fresnel, which occupy a large amount of sunlight and sends it to a special point, the bending of light rays and focusing them. The principle is similar to using a magnifying glass to focus sunlight at podzhiganii paper. In the solar concentrator is a lens is installed on each solar cell. This technology allows us to significantly reduce costs by using less material.
