Solar panels in our life

Alternative sources of nutrition are increasingly entering our everyday life. Companies and enterprises are interested in using them. The policy of many states is aimed at replacing traditional sources of electric power, which have certain shortcomings, alternative ones. Such devices are characterized by good performance characteristics and their use is advisable in the modern world. A good example can serve as solar batteries, on the basis of which whole solar power stations are built. Such devices are widely used in electronics, as an autonomous power source for many household appliances.

The sun is a gigantic energy source, which can be fully adapted for our needs. As a result of nuclear fusion, a star generates in such a second a quantity of thermal, electromagnetic and other types of energy that it would be possible to provide the whole of humanity for half a million years ahead. Modern solar panels are currently transforming an infinitesimal part of this radiation.

Without going into the technical details of the operation of such devices, we can briefly review the principle of the action on which solar panels operate. It is quite simple: they convert the energy of radiation into electrical energy, which is transmitted to working devices or accumulates in storage batteries.

Modern solar panels differ in power, design features and scope. A good example of their use can serve as an ordinary lantern, designed for street lighting. It does not need to run a power cable, it does not consume electricity. With its help it is possible to solve the problem of lighting in the dark.

In addition, autonomous power sources are mobile enough and widely used far from cities, for example, in hiking or exploratory expeditions. Solar batteries for the laptop will provide a full charge of the battery of the device. Their use is expedient far from the main power sources. The size of the battery is optimized for the average user and its transportation will not cause problems. They are distinguished by their power, they can easily be used as a constant source of power during the daytime, for example, for a radio receiver.

At present, work is under way to increase the efficiency of solar batteries. Recall that the theoretical limit on the efficiency for such devices does not exceed 43 percent. The rest of the energy is spent on useless heating of the panels, which worsens not only their technical characteristics. Excessive heating of the device reduces its service life and can disable the battery. With the increase in efficiency, additional opportunities are opened to reduce the area used and, accordingly, this will affect the overall dimensions.

The appearance on the market of devices that provide household appliances with alternative sources of energy, radically changes the very idea of their application. Independence from the supply network provides additional opportunities for the average consumer.
