Solar Energy

Solar Energy

• Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis, which can make considerable contributions to solving some of the most urgent energy problems the world now faces.

 

What is solar energy used today?

• Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy.

 

Solar energy is used only one particular method?

• Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

 

Where to use passive solar energy?

• Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy.

 

What is the active solar energy?

Sometimes architects are using both types of energy at the same time

Solar  energy is free and inexhaustible.

 

Solar panels spoil the landscape and occupy large areas
