How Does Solar Energy Gathered

It also does not emit greenhouse gases or toxic materials.

How does solar energy gathered.

The silicon has electrons in it that when hit by sunlight causes them to become active and create electricity. Just 18 days of sunshine on earth contains the same amount of energy as is stored in all of the planet s reserves of coal oil and natural gas. The solar energy generated by the pv array is direct current dc electricity which cannot be used by many electronic devices or returned to the electrical grid because they use alternating current ac power. Solar energy is clean.

The popularity of solar power has led to the rise of another renewable technology. Also solar arrays do not generate a consistent amount of power because of variations in the amount of light hitting the pv cells. Because the intensity of solar radiation at earth s surface is so low these collectors must be large in area. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending.

Solar batteries that can store extra solar power for later. The solar resource is enormous. One is by direct thermal means the sun s heat is used to heat a liquid heat transfer medium in glass tubes usually the sun s rays are focussed. According to the solar energy industries association the solar market is expected to double in size by 2023 becoming a 4 5 billion market by that time.

Among the most common devices used to capture solar energy and convert it to thermal energy are flat plate collectors which are used for solar heating applications. Even in sunny parts of the world s temperate regions for instance a collector must have a surface. Solar energy power from the sun is a vast inexhaustible and clean resource. Solar energy is gathered by using solar panels to convert the sun s energy into electricity.

Solar energy is radiant light and heat from the sun that is harnessed using a range of ever evolving technologies such as solar heating photovoltaics solar thermal energy solar architecture molten salt power plants and artificial photosynthesis. After the solar technology equipment is constructed and put in place solar energy does not need fuel to work. The solar panel is made up of silicon wafers that have wires attached inside to transfer the energy to the location that it is needed. There are two different ways to gather solar energy.

Using solar energy can drastically reduce the impact we have on the environment. When it does solar may well become one of the dominant power sources in the global energy mix.
