Despite the fact that solar energy has been used for many years, the technology remains considered to be generally new. As people focus too much on advantages, therefore, the disadvantages of solar energy are often overlooked, and many fall pray to difficulties, needing to invest a bundle on a solar array that will not really work correctly for one reason or another.
If you’re truly serious about using solar energy to provide your house with electricity, therefore, you may find that a thorough knowledge of its disadvantages is crucial. Like that, should you choose your research properly, and weigh every point carefully, you may find that you possibly can make the best decisions, and benefit from the numerous good points that solar powered energy comes with.
The Contrast between Solar and Other Green Energy Sources
Solar energy has been successfully used as a power source for over 50 years. Its advantages are well-known to those people who are even remotely enthusiastic about the development of alternate power sources; however, the truth is that, in comparison with some other “green” methods of power production, solar powered energy isn’t 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 are more popular, Energia solar and new designs are being developed all the time, so that it can be viewed as as a viable solution for the future. When you compare it with solar energy, wind power is generally seen as being at an identical level. It is higher priced; however, it comes with one advantage over solar energy, since solar energy doesn’t work at night, for example. On one other hand, wind power can just only be harvested in specific locations where the elements conditions are appropriate.
This same problem arises when comparing solar powered energy to one other two energy sources too. Hydroelectricity is somewhat less clean, however, even though that it generally does not produce direct waste. Geothermal power is incredibly very theraputic for the environment on one other hand, being similar to solar energy in this regard; however, solar powered energy is less efficient.
Nevertheless, geothermal energy remains being researched, as you’ll find so many issues with it, as the technology is not yet advanced enough to allow regular individuals to benefit from it directly, by building their particular power sources. In this regard, solar panels really shine, as, despite the price, they may be easier to manufacture, and maintenance issues are usually 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 can be quite discouraging. Needless to say, the investment mostly depends upon the size of the household, in addition to on the kind of solar energy source you intend to use.
A 1 kwh photovoltaic system can range somewhere between $8,000 and $10,000. Whenever we think of the truth that a family surviving in a 3-bedroom home requires a system that will provide about 1 to 3 kw, the expense of a viable and generally stable solar panel system can double, or even triple.
Solar hot water systems are often a great deal more accessible, however, requiring an investment of roughly around $2000 to $4000. That is good news for many who would prefer to split up their energy sources, and perhaps use multiple systems for better efficiency.
Better yet, the purchase price for solar panel arrays has decreased considerably before couple of decades. Before that, the expenses were more than 5 times less affordable, and the product quality was significantly less than acceptable for this investment.
As a result with this progress, many scientists are very certain that, soon, the purchase price and efficiency rating of solar energy will undoubtedly be sufficient to allow the replacement of the traditional power grid, and provide people who have a helpful, clean and powerful alternative to most of the energy sources known today.
Also, if you should be up for this, you can get only the parts, and make your own system based on solar panels. Based on your needs, you possibly can make it a great deal more economical, at only a fraction of the purchase price that a regular solar panel would cost. While this is often somewhat difficult, with a little work and effort it can be done.
Needless to say, if you select to produce your own solar panel arrays, you will probably encounter a lot of difficulties, particularly if you are not used to building things from scratch. Also, in order to lower the expenses, you may need 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. That is, obviously, an advertising strategy, as well, and there is no reason you can’t build a great, viable solar panel. The time and effort might be too much for a few, but if you prefer doing some traditional fashioned work, the odds will undoubtedly be favorable.
Another difficulty, whatever the quality of the solar array you use, may be the difference between various locations. The key disadvantage in this regard has regarding places where sunlight isn’t consistently available.
As an example, in places closer to the poles, during winter months season, sunlight rarely even makes its appearance for higher than a few hours. This can ensure it is extremely tough to use solar panels for consistent energy production. Also, in areas where the elements is very overcast, rainy or foggy, solar panels do provide some energy, but the efficiency is significantly reduced, and you might need more than the estimated amount in order to successfully provide electricity for your complete household.
Needless to say, if your home is in a place where in actuality the rain doesn’t fall all that often, and there is an abundance of sunshine almost every day, a solar panel array may be the best choice for you. Based on other factors, such as the area you’ve readily available for it, and the size of the panels themselves, you may be able to reach positive results in this case.
Pollution and Long Term Inconsistency
Solar energy might be clean from the general viewpoint, however, it’s still vulnerable to pollution, as this factor can diminish the efficiency of a solar panel. While all the newer designs don’t have trouble with this, older models can be quite easily affected, whilst the technology was not so advanced before, and the materials used were significantly less reliable.
Whilst the solar panels themselves may not pose a risk to the environment, if you should be using an off grid system, the chances are high that you’ll require to use lead acid batteries. Their lifespan is much less favorable than that of a solar panel (roughly 5 years for the battery, in contrast with 20 to 30 for the panels).
As a result, not just are you currently up against additional periodic costs, but the lead and sulfuric acid included in the batteries can prove to be quite detrimental for the environment. Improperly managed, their use can result in considerable problems.
There are ways for this, obviously, as significantly more than 90 % of the materials present in lead batteries can be recovered in the recycling process. The thing you need to accomplish, 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 can be said that there are a large amount of disadvantages as it pertains to using solar energy being an efficient power source for your home. As we’ve seen, however, all of these drawbacks be determined by the ability of individuals to determine just what they need, and compare the outcome for their abilities. With a correct assessment of the specific situation, you could actually manage to come up with a viable solution.
