The Advantages of Solar Energy Technology in Our Life
Posted: Jan 12, 2016
Although solar energy does have its downsides, such as intermittency, where it has to be combined with a form of storage or other source of energy, it still has many advantages of it. Such advantages include reliability, cost, environmental friendliness, aesthetics, and sustainability. Solar energy, for one, is more reliable than wind power and hydro power. This is because the sun will continue to rise for the next 4 billion years without fail, whereas, wind and water might not be available daily. In cases such as during the night and cloudy nights, where solar power is not useful the problems are eased as intermittency is 100% predictable. Furthermore, another advantage of solar power is that although clouds diminish solar power it does not eliminate it.
One essential advantage of solar collectors is that they require minimum maintenance one installed and also provides free energy. Additionally, although solar cells do wear out, their lifespan is measured in decades. The durability of photovoltaic cells improves year by year. More importantly, even though solar cells have been an expensive method of generating electricity, this cost is reducing per kilowatt per year. In addition, solar cells also operate cheaply after installation. Furthermore, solar power has its advantages when it comes to environmental friendliness. Nowadays, everyone is going "green" in order to conserve and protect our earth. Solar power is an efficient way of going green, since it produces zero pollution.Solar powered generators are known not to even produce any noise! Moreover, even though solar energy requires a lot of space, space that is found on rooftops of existing structures is more than enough to produce an adequate amount of solar energy without occupying any extra land area. One of the advantages of solar power is that it is estimated that our earth is continually flooded with 175 trillion Kilowatts of solar power per day. This means that there is an extraordinarily reliable annual energy supply of 1,530,000 Terrawatt hours daily. On the other hand, resources such as oil, coal, gas, nuclear power and wood produce 15 times LESS than this. So presuming that the sun is going to keep on shining for another estimated 4 billion years, solar power is a highly sustainable resource.
