Even though that solar energy has been used for many years, the technology continues to be regarded as generally new. As people focus too much on advantages, therefore, the disadvantages of solar energy are often overlooked, and many fall pray to difficulties, having to invest a bundle on a solar array that will not work effectively for one reason or another.
If you should be truly intent on using solar energy to offer your property with electricity, therefore, you will see that the thorough knowledge of its disadvantages is crucial. Like that, should you choose your research properly, and weigh every point carefully, you will see that you can make the best decisions, and take advantage of the numerous strengths that solar energy comes with.
The Contrast between Solar and Other Green Energy Sources
Solar energy has been successfully used as a power source for more than 50 years. Its advantages are well-known to those who find themselves even remotely enthusiastic about the development of alternate power sources; however, the simple truth is that, in comparison with some other “green” ways of power production, solar energy is not considered to stay first place when it comes to efficiency or consistency.
Its main rivals are: geothermal energy, wind power and hydroelectricity. Wind turbines are only just starting to be popular, and new designs are now being developed all the time, so it can be viewed as as a feasible solution for the future. When you compare it with solar energy, wind power is generally viewed as staying at a similar level. It is more expensive; however, it comes with one advantage over solar energy, Paneles fotovoltaicos since solar energy doesn’t work at night, for example. On another hand, wind power can only just be harvested in specific locations where the current weather conditions are appropriate.
This same problem pops up when comparing solar energy to another two energy sources too. Hydroelectricity is somewhat less clean, however, despite the fact that it doesn’t produce direct waste. Geothermal power is extremely beneficial for the environment on another hand, being much like solar energy in this regard; however, solar energy is less efficient.
Nevertheless, geothermal energy continues to be being researched, as there are numerous difficulties with it, because the technology is not yet advanced enough to allow regular individuals to take advantage of it directly, by building their own power sources. In this regard, solar panels really shine, as, despite the price, they can be easier to manufacture, and maintenance issues are often rare.
Manufacturing and Buying Costs
Among the greatest disadvantage of solar panels is their cost. Both when it comes to manufacturing and buying them ready-made, the expenses could be very discouraging. Needless to say, the investment mostly depends upon the size of the household, along with on the kind of solar energy source you wish to use.
A 1 kwh photovoltaic system can range approximately $8,000 and $10,000. Whenever we consider the fact a family living in a 3-bedroom home requires something that will provide about 1 to 3 kw, the cost of a feasible and generally stable solar panel system can double, as well as triple.
Solar warm water systems usually are a lot more accessible, however, requiring an investment of roughly around $2000 to $4000. This is good news for folks who would like to split up their energy sources, and perhaps use multiple systems for better efficiency.
Even better, the cost for solar panel arrays has decreased considerably before handful of decades. Before that, the expenses were over 5 times less affordable, and the standard was significantly less than acceptable for this kind of investment.
Consequently of the progress, many scientists can be confident that, soon, the cost and efficiency rating of solar energy will soon be good enough to allow the replacement of the standard power grid, and provide individuals with a helpful, clean and powerful alternative to lots of the energy sources known today.
Also, if you’re up because of it, you should buy only the parts, and make your own personal system predicated on solar panels. Based on your requirements, you can make it a lot more economical, at only a fraction of the cost that the regular solar panel would cost. While this is often somewhat difficult, with a little work and effort it may be done.
Needless to say, if you choose to produce your own personal solar panel arrays, you will probably come across plenty of difficulties, particularly if you are not used to building things from scratch. Also, in order to lower the expenses, you might have to use lower quality materials that will not last on a longterm basis.
Manufacturers often emphasize the difference in quality and reliability between a solar panel they make and one that an inexperienced worker may put together. This is, obviously, an advertising strategy, as well, and there is no reason you can’t build a great, viable solar panel. Your time and effort may be too much for some, but if you like doing some good old fashioned fashioned work, the odds will soon be favorable.
Another difficulty, regardless of quality of the solar array you utilize, may be the difference between various locations. The main disadvantage in this regard has related to places where sunlight is not consistently available.
As an example, in places closer to the poles, during the winter season, sunlight rarely even makes its appearance for higher than a few hours. This may allow it to be extremely tough to make use of solar panels for consistent energy production. Also, in areas where the current weather is specially overcast, rainy or foggy, solar panels do provide some energy, nevertheless the efficiency is significantly reduced, and you may want more than the estimated amount in order to successfully provide electricity for your entire household.
Needless to say, if you reside in a place where in actuality the rain doesn’t fall all that always, and there is an abundance of sunshine nearly every day, a solar panel array might be the best option for you. Based on other factors, like the area you’ve readily available for it, and the size of the panels themselves, perhaps you are able to accomplish excellent results in this case.
Pollution and Long Term Inconsistency
Solar energy may be clean from the general standpoint, however, it is still susceptible to pollution, as this factor can diminish the efficiency of a solar panel. While all of the newer designs don’t have trouble with this particular, older models could be very easily affected, since the technology wasn’t so advanced before, and the materials used were considerably less reliable.
As the solar panels themselves may not pose a threat to the environment, if you’re using an off grid system, the chances are high that you might want to make use of lead acid batteries. Their lifespan is a lot less favorable than that of a solar panel (roughly 5 years for the battery, in comparison with 20 to 30 for the panels).
Consequently, not only are you confronted with additional periodic costs, nevertheless the lead and sulfuric acid within the batteries can show to be quite detrimental for the environment. Improperly managed, their use can lead to considerable problems.
You will find ways for this, obviously, as a lot more than 90 % of the materials within lead batteries could be recovered in the recycling process. Things you need to do, therefore, is to ensure that you extend the lifespan of the batteries for provided that possible, and bring them to a recycling facility afterwards.
Generally, it may be said that there are certainly a lot of disadvantages in regards to using solar energy being an efficient power source for your home. As we have seen, however, many of these drawbacks depend on the capability of people to find out exactly what they require, and compare the outcome for their abilities. With a correct assessment of the situation, you could actually have the ability to produce a feasible solution.
