Photovoltaic Solar Panels
Photovoltaic solar panels presently represent the most reliable source of alternative energy and the potential chance to save our planet from the toxic fumes resulting from fuel-based energy production. The manufacturing of photovoltaic solar panels has reached such an extent over the last few years that statistics indicate a yearly growth of 48% at the international level. For the moment, this is actually the fastest to develop energy technology. The figures at the end of 2007 indicated a 12,400 megawatts production globally with the mention that much of this capacity is due to the presence of the grid-tied electrical structures.
The three leading countries in the use of photovoltaic solar panels for energy production are Germany, Japan and the United States, and unfortunately they make almost ninety percent of the photo-voltaic capacity of installed systems all over the world. What about the rest of the countries with a higher solar potential than Germany for instance? China is also making efforts to create the largest wafer structure in the world, with a crushing capacity of 1,500 MW. Such a massive use of photovoltaic solar panels would eliminate part of the immense pressure put on the environment opening the door for even further applications at both the micro and the macro levels.
The production and installation of photovoltaic solar panels has reached the level of industry in Germany; ten thousands people work in this activity sector and most of the PV installations in the European Union rely on the German solar power sources. Unfortunately the global demand for electricity is far too high for a few countries to cover by the simple use of photovoltaic solar panels. Once such products will be made more accessible to the average user by affordable prices, things will change significantly. There is one other aspect incompatible with the use of photovoltaic solar panels.
A huge number of people all over the world do not live in individual homes that allow for the installation of photovoltaic solar panels on their roofs; they live in apartment buildings that would thus need to be supplied with energy by special power wafers created for the unique purpose of converting solar energy into electricity. This factor combined with the huge expenses required by the installation of the photovoltaic solar panels, and you've got the explanation for the relatively little use of alternative energy sources at the global level. Until things change in these directions, hopes of improvement remain very few.
