Solar Power Energy
Although not many people understand the concept, use of solar power, otherwise known as
solar energy, is well known in very many parts of the world. Energy from the sun
has been used for very many years now, both knowingly and unknowingly. The two major benefits of solar energy are that it does not use fossil fuels in its production and that it will never run out. It is renewable
energy.
One of the initial incidences when solar power was used was back in the 1800’s when
explorers collected heat from the rays of the sun using a box and used it to cook. Solar energy entails harnessing
heat and light from the sun and using it for various uses both in homes and in industries. According to studies, a
very tiny portion of the heat from the sun is actually being converted into energy. 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.
When harnessing energy from the sun, people use heat engines as well as photovoltaic
devices. 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 and solar cells are designed to convert the
energy into electricity and can be used to power watches and calculators. Photovoltaic panels and other
manufactured solar energy collectors are normally classified as the active harnessing technologies while passive
technologies involve using building materials that make it easier for energy to be collected from the sun. They are
the specific designs incorporated into buildings to ensure that light is dispersed into most parts of a
room.
Solar energy can be used in very many ways by people all over the world.
Increasingly, the benefits of a solar energy home
are being understood. Lighting is the original and most commonly used application of solar
energy. The correct use of skylights and windows in buildings reduces the amount of artificial lighting required in
such buildings. Using solar water
heaters or other types of heaters to warm up rooms or heat water is another common
application of solar energy. Swimming pools can also be heated in this way. Building a solar water heater is not expensive and is
easily doable by a DIY enthusiast.
Conversion of heat from the sun into electricity involves using solar panels and this is an
active solar power collecting technology. 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 means that people have to collect the all the energy that they require in the period when the sun
rays reach the earth.
