Solar Energy - How Can We Use It? by Howard Puddy
... There are 4 main ways that solar energy from the sun is captured, these are:• Flat plate liquid filled solar panels for water heating • Flat Plate Gas filled solar panels for space heating • Photovoltaic cells for electricity generation • Passive Solar Heating Flat Plate Liquid filled solar energy panelsA flat-plate liquid solar energy collector is basically a metal box, usually insulated, that has a glass cover over a dark coloured metal plate (copper or cheaper aluminium).

Types of Solar Energy by Anne Clarke
... · Solar Updraft Tower – This is a type of solar energy plant in which air passes under an agricultural glass house, gets heated by the sun, and is then channel up toward a convection tower. It is used to drive turbines which generate electricity. · Energy Tower – This tower uses water, unfortunately, but it is also a good design and works in a similar way to the solar updraft tower. Water is sprayed at the top of the water. The water evaporates which causes a downdraft by cooling the air.

A Closer Look At The Alternative Energy Sources Of Solar And Wind Power by Gregg Hall
... An active solar heating system uses pumps to circulate water which has been heated by the sun. Passive solar heating systems use the nature of water to create circulation. This method relies on the fact that heat energy wants to move into areas of lesser heat. In generating electricity, solar power is harnessed by photovoltaic cells which convert the suns energy into electricity. These cells have been widely used to power calculators for decades.

What is Solar Power? by Anne Clarke
... 1) Solar water heating is a part of what is solar power. Basically, heat from the sun is used to heat water through glass panels on your roof. Therefore you do not need to use as much gas and/or energy to heat your home. 2) Solar furnaces are also a part of what is solar power. Solar furnaces use many mirrors strategically placed in order to concentrate all of the sunlight it possibly can. This small space of concentrated energy is then released from its place and used to provide extremely ...

Solar Power How It Works by Anita Van Wyk
... 3.) Solar energy works by converting the sun's rays into hot air for heating buildings with the use of solar thermal collectors. How do solar panels work? 1.) Rays of sunlight hit the solar panel (also know as a photovoltaic/ PV) and are absorbed by semi-conducting materials such as silicone. 2.) Electrons are knocked loose from their atoms, which allow them to flow through the material to produce electricity. This process whereby light (photo) is converted into electricity (voltage) is ...

Alternative Energy, The Dream And The Reality by Allen Goldstone
... Active solar involves installing solar collectors that capture the sun’s heat and transferring it to a liquid for household or commercial hot water applications. The newer form of active solar utilizes photovoltaic cells similar to semiconductors that convert the sun’s energy to electricity. In simple terms, the solar energy knocks electrons loose from their atoms allowing them to flow through the material to form electricity. Photovoltaic applications have been limited to low power devices ...

Save On Energy Bills With Solar Home Heating For Hot Water by Lee Dobbins
... This is called passive solar water heating. Before the beginning of the 21st century, states like Los Angeles and Florida have already taken advantage of passive solar hot water systems. There were a number of sytems using solar water heating that are located in the mentioned states' roof tops. Nowadays, the solar water heater is referred to as PSWH, Bread Box and Batch Heater. However, the technical term for this contraption is the Integrated Collector and Storage System or ICS for short.

Here Comes The Sun: Solar Energy is Becoming More Attractive for Mainstream Consumers by Kavar Peter
... grid that is becoming more and more fragile as demand outstrips supply. No wonder solar power is getting attention! Solar power is still more expensive than traditional energy production methods, but the gap is narrowing every year. Solar power applications are also multiplying at an amazing rate. House heating, solar pool lighting and heating, hot water tank heating, calculators, flashlights, solar garden lighting and on and on. Solar is clean, it’s efficient and it’s here to stay.
