Introduction:

Solar energy can simply be said to be the radiant heat and light that the sun produces and is harnessed through the use of a variety of technologies that are ever-evolving like photovoltaic, solar heating, solar architecture, thermal energy, artificial photosynthesis and power plants of molten salt. Solar energy is one very vital renewable energy source and the technologies of solar energy are widely categorized as either active solar or passive solar based on the manner of capture and distribution of the solar energy and how the solar energy is converted to solar power.

The techniques of active solar include using water heating that is solar, solar power that is concentrated and photovoltaic systems to harness solar energy. The techniques of passive solar include the design of space that will circulate air naturally, selection of materials that have light dispersing or thermal mass properties that are favourable and the orientation of a building towards the sun. Solar energy is a very appealing electricity source because solar energy is readily available in large magnitude. Research has shown that while the total consumption of energy all over the world annually is 559.8 EJ, the potential energy generation of solar energy is 1.575 EJ to 49,837 EJ which is a lot more than what is needed.

Potential of Solar Energy:

The potential of solar energy which can be used is quite different from the quantity of solar energy that is present close to the planet earth’s surface as a result of different factors like time variation, geography, available land and cloud cover, all limit the quantity of energy that can be acquired through solar sources.

The potential of solar energy is affected by geography because all the areas very close to equator get a greater quantity of radiation from the sun. The potential of solar energy can be greatly improved following the sun’s position through using photovoltaic in the areas that are not close to equator.

The potential of solar energy is affected by time variation because there is usually little or no solar radiation during the night on the earth’s surface that the solar panels can absorb. The potential of solar energy is also affected by cloud cover because incoming light can be blocked by clouds preventing it from reaching the earth’s surface from sun and this goes a long way in the reduction of the available light that solar cells can use.

The potential of solar energy is also affected by land availability because we can only set solar panels up for use on the land usually not in use and very suitable for the foxing of solar panels. It has been discovered that very suitable place to fix solar cells are roofs, since a lot of people have come to the realization that they also can directly collect energy from their houses through this means. We can also establish solar plants on areas of land which are not in use for business or other things.

Urban Planning and Architecture:

The design of buildings has been greatly influenced by sunlight ever since architectural history began. Methods of urban planning and solar architecture that is advanced were first used by the Chinese and Greeks; they made the orientation of the buildings they constructed to the south so that warmth and light can be provided.

Features of solar architecture like compact proportion ( ratio of surface area and volume), orientation, thermal mass and selective shading are all tailored to that particular environment and local climate so that spaces that are well can be produced and the building remains in a temperature range that is very comfortable. Ventilation systems, heating and solar lighting are all tied together in the solar design.

Conclusion:

In the times of global warming and climate change as a result of the pollution of the atmosphere through the emission of smoke from the burning of fossil fuels, it is very important that alternative sources of energy that are renewable are gotten. Solar energy is one energy source that does not negatively affect the environment and cannot be exhausted.

When we develop solar energy and its technologies that are clean, inexhaustible and affordable, we are bound to enjoy benefits that are huge and long-term. Solar energy can go a very long way in increasing the energy security of a country as a result of reliance on inexhaustible, indigenous and largely non-import resource, reduce pollution, enhance sustainability, lower the prices of fossil fuels and lower the price and cost of curbing global warming. All of these advantages of solar energy are global.
