Facts about Solar Power 

Solar energy is a well known concept around the world although not many people completely understand it.Energy from the sun has been used for very many years now, both knowingly and unknowingly.One of the first ingenious uses of energy from the sun was back in the 17th century when explorers harnessed energy from the sun using collection boxes and used the heat to cook food.Solar power involves using power collected from the heat and light and using it for many uses in homes and at work.According to scientists, a very small percentage of the energy from the sun is actually being harnessed. This is mainly because some people in developed countries have all the power they require that they do not see the point in harnessing energy from the sun while other countries do not have the technology required to do it.

Generating energy from the sun involves the use of photovoltaics and heat engines.These technologies can be classified into passive and active technologies depending on the way they are used to collect energy and convert it to power.Photovoltaic devices or cells from the sun are directly harnessed from the sun to form electricity that can be used for lighting and powering tools such as calculators and watches.Devices manufactured for collecting sun energy as well as photovoltaic devices are classified into active technologies while designs and building materials that make it easier for inhabitants to convert heat and light into energy are classified into passive technologies for harnessing energy from the sun.They include materials that allow dispersion of light as well as designs that make it possible for light to fill a room or an office.

People use solar energy in many different ways all over the world.Lighting is the most commonly used application.Incorporating skylights and windows when building reduces the amount of artificial lighting required in that building.Using solar water heaters or other types of heaters to warm up rooms or heat water is another common application of solar energy.People also use solar water heaters to heat up swimming pools.Active solar harnessing technologies include the use of solar panels to convert heat from the sun into electricity.However, there is a drawback involved in this technology in that certain parts of the world receive sun rays at certain times of the year based on the season, location and weather condition.This therefore means that people have to ensure they have collected as much energy as possible while the sun still shines.
