Solar Power Alternative To Electricity 

Solar power and many other alternative sources of fuel are becoming increasingly popular because fossil fuels are a finite resource that is becoming  harder to find, harder to get out of the ground and more expensive for the household consumer. Given these basic economic facts and the fact that developing countries like India and China are making greater demands on the worlds fossil fuel supplies it is not surprising that much attention has shifted to solar power. Countries like Japan and Germany lead the way in solar power research and development. Many communities in these countries have solar panels and are partially or self-sufficient for their household energy needs. US states like California are also jumping on the solar power band wagon with grants for research and rebates for homes that install solar panels. But what exactly is solar power and is it a viable alternative to electricity in the home ?

Solar power is a form of energy derived from the sun and then converted into electricity or heat. The major advantage of solar power is that it is a renewable source of energy that is free (provided the Sun continues to shine) after initial installation. It is versatile as it can be used to create electricity for the home, lighting for the garden, rechargers for batteries and numerous other applications.

How Does Solar Power Work

Using solar collectors, energy from the sun is converted into electricity. These solar collectors or  solar panels, consist of  banks of solar cells aligned in a sequential or parallel arrangement. Depending on your needs the quantity of cells will vary. The solar panels need to be pointed towards the most direct source of sunlight in order to absorb the highest possible amount of solar energy.

There are two ways that the suns energy can be converted into solar power. The first is to use solar thermal applications which use the energy from the sun to provide direct heat for air or liquid. You can use solar thermal panels for both residential and larger scale applications or needs.

The second method is to use solar power through photoelectric applications. These applications use photovoltaic cells to convert the suns energy into electricity. These cells are considered low maintenance and work well for remote applications. To convert the suns energy into electricity these applications use semiconductors similar to silicon.

Is solar power an alternative to electricity ? In some parts of the world it is a necessity. Remote areas that are off the grid have no alternative but to use solar power. In built up conurbations, especially in warm and sunny climates, you will see more and more solar panels on roofs or in gardens. The truth is that there is increasing political will to make solar power work. This means more research will be done to make the solar cells more efficient and cheaper. This will make the take up of solar power increase and will become even cheaper. If you live in a warm climate that receives plenty of sunlight, it is only a matter of time before you use some form or solar power to create electricity or energy  for your home.
