Solar power systems are generally devoted to the production of electricity. They do this by two methods of operation. The first is through a direct conversion process achieved via the use of photovoltaic cells. The second is an indirect type. A series of collectors together focus sunlight into a beam which will produce huge heat levels. That heat is then coupled to a conventional thermal power production unit.
Countries considerable in number are making use of a variety of these types of production. Germany and Portugal are among the many to announce recently that they have finished high yield production plants of this sort. The United States and others as well have mulitple plans in various stages of development.
One major problems found with these traces back to the fact that sunlight does not reach the ground in a constant manner. It does not get there at all when it is night. The space after sunrise and before sunset see so little of the sun's energy that is is not enough for electrical production to take place. Fog or clouds can also interfere with operation.
These plants also have to overcome problems that relate to low density levels. What this entails in performance is the need to erect considerable numbers of collectors to make up for the small amount of energy each can obtain. Vast tracts of land can be consumed due to this. There will need to be a large outlay at the start to acquire all the raw materials.
There are low powered gadgets like watches that need not worry about this since their requirements are minimal. Satellites also have a superior position to take advantage of this type of energy. They float way above the clouds in an environment of unvarying sunlight.
Solar power systems continue to advance in design and output. All indications are that this will continue to be the case. Fears of global warming and fossil fuel shortfalls are driving production forward.
