What is Solar Energy?
The Solar Energy emanating radiant light as well as heat through the sun, have been harnessed by humans since ancient times having a selection of ever-evolving technologies. Solar energy technology which include solar heating, solar photovoltaic’s, solar thermal electricity and solar architecture will make significant contributions to solving probably the most important problems the entire world now faces.
Solar technology is generally characterized as both active solar or passive solar with regards to the way they capture, distribute and convert solar energy. The active solar techniques include using photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques involve orienting a building on the Sun, choosing materials with beneficial thermal mass or light dispersing qualities, and designing areas that naturally circulate air.
In the year 2011, the International Energy Agency declared “the growth and development of inexpensive, inexhaustible and clean solar energy technologies may have huge longer-term advantages. It’ll improve countries’ energy protection through reliance upon an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the expense of mitigating climate change, and lowe fossil fuel use. These benefits are global. Hence the additional costs from the incentives for early deployment should be spent well and need to become widely shared”
The Advantage of Solar Power
Lots of the good things about solar power are clear. Environmentally friendly advantages alone are sufficient to justify thinking about using solar power. Presently there would beless clear advantages also; solar energy systems need very little maintenance, a solar energy system will give you continuous service when public utilities have outages, a solar energy system will give you power in remote places that public resources are unavailable and, after setup, the continuing cost of solar power is extremely small.
There is obvious environmental advantage of solar power. Solar power creates absolutely no continuing pollution. There might be some produced throughout the creation of the batteries and panels but there’s no continuing pollution thereafter. Solar systems consume no fuel of any sort except sunlight to create power.
The Disadvantage of Solar Energy
The primary disadvantage that solar energy has for many individuals will be the initial installation cost. The first set-up of the equipment has become quite expensve for an average family but everything has improved in the past several years with reduced prices and nice government subsidies and refunds available.
Solar energy remains the best clean renewable alternative source to make use of in comparison to dirty fossil fuel technologies. With the cost of using solar energy decreasing there’s apt to be a common increase using the solar panels to create electricity for home and industrial reasons.
Another disadvantage to solar power installation is it takes a large available area (generally roof space) for that system to some sufficient KWh size to become efficient in supplying a sizable electric source. This is often a condition in high density cities where space is minimally available. . High Pollution may also result in a problem with the solar power panels as it can certainly degrade the efficiency from the PV cells.
