Solar energy facts
Solar energy is actually energy from the sun.
could be converted directly or even indirectly in to other kinds of energy.
Also learn Interesting Facts about Energy
Solar energy is also known as solar power.
Solar energy is a clean energy source.
Solar energy doesn't produce waste or even pollution and it is ecologically accepted.
Solar energy drives climate and weather as well as supports all life on the planet.
Solar energy technology is with all the Sun's energy regarding practical purposes.
Solar energy usually identifies photovoltaic as well as focusing solar thermal technologies that will convert Sun's energy directly into electricity.
Since the solar energy comes from the sun to us as light in the form of photons, and also heat radiation will be dispersed, reflected, transmitted, or even absorbed. Most of this energy is absorbed through the earth's atmosphere out of which 35 % is reflected back to space. Parts of the energy spectrum which can be blocked from us are extremely harmful like ultra-violet (UV). Fortunately, just about all UV light will be blocked by our atmosphere. The way the sun's energy responds to materials is integral to the way in which electricity is actually created via photovoltaic panels as well as solar thermal.
Advantages of Solar Power?
Solar energy is really a neat and renewable power source.
When a solar panel is installed, solar energy can be accomplished free of charge.
Solar energy can last forever whereas it's estimated that the world's oil reserves can last for 30 to 40 years.
Solar energy leads to no pollution.
Solar cells make simply no noise in any way. However, the giant machines employed for pumping oil are incredibly noisy and for that reason very impractical.
Almost no maintenance is required to keep solar cells running. There aren't any moving parts inside a solar cell that makes it impossible to really damage them.
Ultimately, there might be a high return on investment because of the quantity of free energy a solar panel may produce; approximately the average household might find 50% of the energy arriving from solar panels.
Disadvantages of Solar energy?
1. Solar panels could be expensive to install causing a time-lag of several years for savings upon energy bills to match initial investments.
2. Electricity generation will depend on entirely on the countries experience of sunlight; this might be limited by a countries climate.
3. Solar power stations usually do not match the energy output of similar sized conventional power stations; they may also be extremely expensive to build.
4. Solar power can be used to charge batteries to ensure that solar powered devices can be utilized at night. The batteries is often large and high, taking on space and having to be replaced every once in a while.
