Types of Solar Energy Storage

Man, through various processes, has managed to transform solar energy so that we can now distinguish three types:
1 - Solar photovoltaics: Occurs when a portion of the solar radiation is converted to a photoelectric cell. Several cells are connected via a photovoltaic module.
2 - Solar thermal energy: this energy is used the heat from solar radiation. It presents a variety of ways: hot water heating, solar cooling, kitchens, solar dryers and solar thermodynamic plants.
3 - Passive Solar: This kind of energy is the oldest that was given to solar energy. It is generally used in buildings or houses. The benefit of using this energy in homes or buildings is that they would be contributing to important energetic savings.

Why is stored solar energy?
solar energy is stored to meet demand because to their availability, in some places, is insufficient.

What are the storage systems?

storage systems are simple water and rock, but you can also use devices that are based on changes in particular phases of the salts that melt at low temperatures.

What are the batteries?

accumulators are used to accumulate the surplus electricity caused by wind or photovoltaic devices.

Advantages and Disadvantages of Solar Energy

solar energy has a wide variety of benefits. These may include:
  • is a renewable energy
  • Reduces pollution
  • It is clean
  • The use of this energy is silent
  • light and heat from the sun can produce heat energy, mechanical, electrical and light
  • solar structures are easy to maintain
Like all energy, it also has its disadvantages. Some of these are:
  • There are places where the planet receives very little light, and this energy can be maximized
  • Only obtained during the day
  • installations of solar collector systems have very high costs
  • are vast tracts of land necessary to acquire this energy in large quantities
