Energy Crisis-How Much does Solar Energy Cost ?

In the fossil energy and carbon emission reductions under the constraints and other issues, people began right after several big new energy to pursue. The hottest areas in which course ought to solar energy .

Soalr energy produced by the Earth for an hour, enough to the world's annual energy needs. This is precisely why the use of solar energy as our dependence on oil from the ultimate way. If we are able to save resources, utilization of solar energy, access to energy net profit, we truly claim to have inexhaustible energy.

Worldwide, solar battery charger has made rapid development, but the use of solar energy far less than the proportion of total global energy consumption by 1%. The high cost of solar charger has not been caused by extensive use of important reasons. The reason why this inexhaustible energy costs high, and natural resources, the vicious circle between the inextricably linked.

Today, most solar powerd charger use silicon as raw material, as compared to silicon and other materials more efficient. However, silicon is a more difficult material. In addition, its manufacturing process also requires a lot of water and energy.

However, when it comes to a crucial question - whether the solar cells have a "net energy" (energy output is greater than consumption of energy)? Either the current or future, we do not have clear answers. Now, to make solar cells directly to lower energy consumption of its output of energy, it looks like it can generate energy net. However, the next conclusion, we have to do some other factors to consider.

Because exposure to sunlight during the daytime only, but not necessarily sunny during the day. If you want to rely entirely on solar energy, must find a way to store solar energy. So far, we have not yet found a cost-effective way to store solar energy for solar charger wholesale . Currently developed two methods - the compressed air and battery storage is very expensive.

Calculate solar cells really can produce net energy, we must consider the construction of the energy storage system energy input. It is only through more detailed study in order to obtain definitive answers. In any case, the performance of solar cells there is a huge geographical difference - the more adequate sunlight area, the higher its efficiency bound.

To our knowledge, solar cells are currently not widely used because: Once the installation and maintenance costs involved, relying on (in particular, is made of silicon raw materials) solar cell power generation, relying on other resources than the cost of producing electricity much more expensive.
