While the benefits of solar energy are numerous, it’s important to understand its disadvantages as well. Following are some of the main disadvantages of solar energy.
Expensive To Install
Installing solar panels is expensive. Even if you opt for the DIY route, you will likely still need an expert installer. You will also have to purchase the materials needed to build the installation, which can add up quickly.
Diminishing Energy Output Over Time
Solar energy is often described as a ‘zero-waste’ energy source because it produces no harmful byproducts during operation. However, this is not entirely true. The output of solar energy gradually decreases as the sun’s radiated energy is deposited into space. To be able to extract the same amount of energy as you put in, you will need to replace or upgrade your panel system at some point in the future.
Decreased Reliability Over Time
As with any technology, hardware failures are almost inevitable. This is due to the fact that solar energy is a continually evolving field, meaning that older technologies will eventually be replaced by newer ones. The good news is that unlike some other technologies, such as coal and nuclear energy, the cost of replacing solar hardware is generally quite low. However, due to the high amount of exposure to nature’s elements, solar hardware does require more frequent maintenance than most other types of energy hardware. Moreover, some experts recommend replacing the entire unit every 10 years or so to ensure that it continues to function as efficiently as possible.
Need For Constant Power Supplies
To operate most devices, especially those that are powered by direct current, you will need a power supply of some kind. Due to the fact that solar energy is a ‘zero-waste’ energy source, you will not need to worry about wasting power through overuse. However, this does not mean that you need to constantly have a power supply with you. In most cases, you will not have any noticeable effects if you forget to charge your electronics device for a couple of days. However, if you forget to charge it for a week, you will begin to experience problems, such as increased memory loss and decreased device performance. The good news is that a solar-powered solution to this problem is just about as easy to install as a traditional energy source.
Inflexible
Unlike some other types of energy sources, such as hydroelectric power and wind power, the amount of energy that you can get from solar energy is quite limited. Due to this, it is generally unsuitable for powering large-scale facilities, such as data centers or office buildings. Additionally, many people are not even aware that they can generate their own energy through solar power. This is why most large-scale installations are generally located in areas where solar energy is abundant, such as the southern states of the United States.
Inconsistent Energy Output
Due to the fact that the amount of energy that you get from the sun varies throughout the year, you will either need to store it or use it quickly. This means that you cannot count on solar energy to provide consistent power. During times of excess energy, you will benefit from its low prices and the fact that it does not cause any harmful byproducts. However, at times of less energy, you will need to either buy additional hardware to generate more energy or find an alternative energy source to meet your needs. Moreover, depending on the time of day and location, you will either need extra hardware or else you will need to manually switch the system on and off so as to avoid any unexpected power cuts – especially in cold weather when you need heat most.
Fluctuating Temperatures
The average temperature of the environment around the earth tends to fluctuate between 10 degrees and 35 degrees. This is generally known as the ambient temperature range. However, the temperature changes significantly depending on the time of day and location. In general, you will either need to add or remove heat to or from your home or workplace in order to maintain comfort – especially in extreme situations, such as hot summers or cold winters. The good news is that while this can be an inconvenience, it is not physically harmful to your home or device.
Dependence On The Weather
The weather is always changing, with both favorable and unfavorable seasons. This is why you need to either store heat or else use it quickly whenever possible. However, this varies from one place to another. In some places, such as Australia, you will need plenty of sun in order to generate enough energy to keep your home or business cool. In other places, such as the northern states of the United States, the weather is more wintry and you will need to add extra heat to your home or workplace. The key is to understand your local weather patterns and use this to your advantage.
Noisy
Due to the nature of solar energy, power plants that generate this type of energy are often quite noisy. This is mostly due to the fact that they are usually found close to large bodies of water, such as lakes, ponds, or the ocean. Moreover, many people living near by sometimes complain about the noise that these plants generate. While this can be an inconvenience, it is usually not physically harmful.
Low Efficiency
The efficiency of solar energy to generate electricity decreases as the area that you are trying to generate power from gets smaller. This is why large-scale installations are often less efficient than residential ones. To maximize the efficiency of your installation, you will need to keep all the surfaces as clean as possible and ensure that there are no obstructions present in the direct line of sight between the sun and the solar panels. Moreover, for areas with less direct sunlight, you will either need to upgrade your system or install multiple solar panels to generate the same amount of electricity.
Limited Energy Density
Due to the fact that the sun’s energy is mostly wavelength range, you will either need a lot of it or else you will need a lot of time to collect it. As a result, you will either need to add or remove a lot of heat from your environment in order to generate enough energy for your home or business. This usually requires either an expensive auxiliary heating system or else a bigger refrigerator to keep your food cold. Moreover, most experts agree that the energy that you get from the sun does not stay in the environment for very long. This means that either you will need to add more sources of energy or else you will need to ensure that your existing sources are operating at their optimum capacity.
