Just How Do Solar Panel Systems WorkSolar energy is an energy supply from the sun. Cellular technology converts power acquired from sunlight into electrical energy. Sorar power panels tend to be arragys of panels which create a considerable quantity of electric power.
Our world receives around 100 watts of solar energy per square meter, so solar power technology promises to be the power of the the future. But the expense of solarcell production and their efficiency are a barrier so far. Nevertheless there is clearly a movement forward as research and study makes further advances. In the foreseeable future there is likely to be people or companies that will make solar cells more accessible to everyday people, especially in developing countries without significant energy investments.
Just how do Solar Panels Generate Electricity?
Solar energy panels are arrays of solar cells linked in series to create electrical energy. First you need to understand how solar works
Voltaic means that the cell converts energy from photons into electricity. There was a time when solar cells were used only in space to run satellites! With technical innovations and private companies entering into the industy, the production of solar cells is becoming more and more feasible. They truly are regularly powering things from calculations to cars to space crafts.
Solar Photovoltaic Cells
Photovoltaic cells are made of materials knows as 'Semiconductors'. The most widely used semiconductors tend to be silicon and germanium. But they can be changed into conducting materials with the addition of tiny quantities of doped elements. These types of doped semiconductors are employed in making photovoltaic cells.
These cells are linked in a closed electric circuit in the sun.
As photons fall on the surface of solar cells, electrons within the semiconductor are freed by the absorption of energy. Every photo is like a missile dislodging electrons from their orbits around atoms. Every ray of sunshine has an incredible number of photons which hit the semiconductor area of a photovoltaic cell.
Every photon liberates electrons from their atomic shells. This creates free electrons in the semiconductor that can move if an electric field is applied across the solar cell. This gives rise to a small current across the semiconductor which is drawn for external use, with metal contacts positioned on the top. The current is quite weak. The effectiveness of solar panels is dependent on the finest production, but even with great manufacturing, usually 70% of the solar energy goes unused.
To transform this tiny electric result in a larger one, arrays of thousands of solar cells are brought together. The electricity produced by each photovoltaic cell| is combined through linking these cells within the panel. The combined electric current production is redirected to a rechargeable battery pack where is ti saved for future use. An important thing about solar clells is that they genereate electrical energy without pollution unlike other sources of energy. Solar energy is progressively used within the developed world but it is still a long way from making inroads into the power hegemony of oil.
Solar power could be the road to an eco-freindly tomorrow. As solar tech becomes less expensive, it could be mass produced in higher quantities to reduce our dependence on main-stream resources of energy that are fast depleting.
