What is Sun or Solar Power?

Solar power is a renewable form of energy acquired from the sun 

The energy from solar rays can be used to produce thermal and electric power after it is captured using photo voltaic (solar) panels. Solar panels are fitted on high-rise buildings as well as household rooftops. Solar energy is captured through other methods as well, including the charging of hand-held electronic gadgets, which is increasingly popular.

Installation of panels on buildings in crowded cities was initially used to heat water and is now more widely used to meet everyday power needs. 

While technology is making incredible advances almost daily, Solar power has relatively high initial installation costs. To work effectively, photo voltaic cells need a certain amount of daily sunlight so not every area or rooftop is a good candidate. It is important to also consider that power output uniformity is not guaranteed in case of bad or cloudy weather and of course there is no daylight at night!

Science Notes

One kilowatt of solar power is equivalent to energy created by 300lbs of carbon. 

A photovoltaic panel comprises of a semi-conductor placed between two electrical contacts. The semi-conductor is coated with a substance used to avoid reflection, so that maximum power is stored by panels. The solar power produces direct current, which is then converted to alternate current before use.

If you are renting a home or your home isn't a workable candidate for solar power, you might want to investigate whether there is a community solar farm near you. Also, if shade is your problem, stay tuned, there are emerging technologies that will see you still able to harness solar energy in the not too distant future.
