The use of solar energy has come a long way from Edmond Becquerel in 1839 discovered how to convert light into electricity. Since solar energy is increasingly used worldwide (which is responsible for 100 gigawatts of global electricity in 2012!), Is logical that we learn how solar energy can be harvested and used in our homes.
Solar energy is mainly harvested by solar panel systems. Solar panel systems, in turn, are composed of solar cells. These cells are fabricated using the element silicon (Si), which are also used in the manufacture of computer processors.
Mono, Poly or thin film?
In most situations, the factors that are considered in choosing the type of solar panel for use of space and cost. So if you are looking for or residential solar kits solar power for commercial use much energy your choice basically boils down to these three:
Monocrystalline. Most solar panels manufactured in the world today have cells that are made of silicon. Monocrystalline silicon solar cells, which are made of highly pure silicon, are very effective especially in very sunny climates, both in terms of converting light into electricity and use of space. They also tend to last longer between types. A drawback, however, is that the single crystal silicon solar cells are also the most expensive.
Polycrystalline. Solar cells made of polycrystalline silicon are simpler and less expensive to manufacture. They are most effective in cloudy climates and consume more energy efficient when the days of sunlight are less frequent.
Thin-Film (aka amorphous). Thin film solar cells can be easily mass produced, reducing costs. When space is not an obstacle, or the panels have to follow a curved structure (instead of flat), solar cells with thin layers of meaning. However, this “advantage” does not make them ideal residential solar kits. How come? Because they are very inefficient compared with mono and poly panels, therefore, must be much larger for the same power. (For example, a 5W panel Mono / Poly can be five times smaller than a thin film!).
Why Go Solar
A report on the world situation in 2013, says: “Renewable energy is spreading to other regions and countries, and increasingly affordable in developing countries and developed countries alike” In our experience, this is especially true – . Solar saw how will it be converted to the remotest villages in a developing country! So, in addition to cost and space, there are very few reasons not to go plot in especially in the community or commercial settings.
