Advantage Of Solar Energy Essay

What are the Advantages and Disadvantages of Solar Energy?

Solar energy is derived from the sun’s radiation. The sun is a powerful energy source, and this energy source can be harnessed by installing solar panels. Did you know that the energy that it provides to the Earth for one hour, could meet the global energy needs for one year? We are able to harness only 0.001 percent of that energy.

There is a reason why solar energy has become a trending topic when talking about renewables. While it has been widely criticised for being expensive or not very efficient, solar energy has now proved to be extremely beneficial - not only for the environment but also financially speaking. Additionally, due to the higher demand, the technology has been improved considerably, turning into a significantly efficient source of clean energy.

GreenMatch has depicted the key advantages and disadvantages of solar power in the following table:

Advantages of Solar Energy

1. Renewable Energy Source

Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source. It can be harnessed in all areas of the world and is available every day. We cannot run out of solar energy, unlike some of the other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years when according to scientists the sun is going to die.

2. Reduces Electricity Bills

Since you will be meeting some of your energy needs with the electricity your solar system has generated, your energy bills will drop. How much you save on your bill will be dependent on the size of the solar system and your electricity or heat usage. Moreover, not only will you be saving on the electricity bill, but if you generate more electricity than you use, the surplus will be exported back to the grid and you will receive bonus payments for that amount (considering that your solar panel system is connected to the grid). Savings can further grow if you sell excess electricity at high rates during the day and then buy electricity from the grid during the evening when the rates are lower.

3. Diverse Applications

Solar energy can be used for diverse purposes. You can generate electricity (photovoltaics) or heat (solar thermal). Solar energy can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space. Solar energy can also be integrated into the materials used for buildings. Not long ago Sharp introduced transparent solar energy windows.

4. Low Maintenance Costs

Solar energy systems generally don’t require a lot of maintenance. You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job. If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35. Most reliable solar panel manufacturers give 20-25 years warranty. Also, as there are no moving parts, there is no wear and tear. The inverter is usually the only part that needs to changed after 5-10 years because it is continuously working to convert solar energy into electricity (solar PV) and heat (solar thermal). Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency. So, after covering the initial cost of the solar system, you can expect very little spending on maintenance and repair work.

5. Technology Development

Technology in the solar power industry is constantly advancing and improvements will intensify in the future. Innovations in quantum physics and nanotechnology can potentially increase the effectiveness of solar panels and double, or even triple, the electrical input of the solar power systems.

Solar Energy Disadvantages

1. Cost

The initial cost of purchasing a solar system is fairly high. Although the UK government has introduced some schemes for encouraging the adoption of renewable energy sources, for example, the Feed-in Tariff, you still have to cover the upfront costs. This includes paying for solar panels, inverter, batteries, wiring and for the installation. Nevertheless, solar technologies are constantly developing, so it is safe to assume that prices will go down in the future

2. Weather Dependent

Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. Solar panels are dependent on sunlight to effectively gather solar energy. Therefore, a few cloudy, rainy days can have a noticeable effect on the energy system. You should also take into account that solar energy cannot be collected during the night. On the other hand, if you also require your water heating solution to work at night or during wintertime, thermodynamic panels are an alternative to consider.

3. Solar Energy Storage Is Expensive

Solar energy has to be used right away, or it can be stored in large batteries. These batteries, used in off-the-grid solar systems, can be charged during the day so that the energy is used at night. This is a good solution for using solar energy all day long but it is also quite expensive. In most cases, it is smarter to just use solar energy during the day and take energy from the grid during the night (you can only do this if your system is connected to the grid). Luckily our energy demand is usually higher during the day so we can meet most of it with solar energy.

4. Uses a Lot of Space

The more electricity you want to produce, the more solar panels you will need because you want to collect as much sunlight as possible. Solar panels require a lot of space and some roofs are not big enough to fit the number of solar panels that you would like to have. An alternative is to install some of the panels in your yard but they need to have access to sunlight. Anyways, if you don’t have the space for all the panels that you wanted, you can just get a fewer and they will still be satisfying some of your energy needs.

5. Associated with Pollution

Although pollution related to solar energy systems is far less compared to other sources of energy, solar energy can be associated with pollution. Transportation and installation of solar systems have been associated with the emission of greenhouse gases. There are also some toxic materials and hazardous products used during the manufacturing process of solar photovoltaics, which can indirectly affect the environment. Nevertheless, solar energy pollutes far less than the other alternative energy sources.

Solar power is electricity that is derived from the sun and there are many benefits associated with its use. This article takes a look at the advantages of solar power and the benefits it can provide.

The Advantages

Below you will find many of the advantages associated with the use of solar power.

1 – It Can Save You Money

Apart from the initial cost and maintenance fees of solar panels, generating electricity from solar energy is completely free. This means that for the operational lifetime of a solar panel, it will be busy saving you money on your electricity bills whilst also providing a pay back on your initial investment. Although there is a long pay back period, a typical solar panel installation will still provide a return on investment (ROI) in a matter of years.

2 – There’s No Pollution

Solar panels do not produce any pollution whatsoever. The only pollution that is generated in relation to a solar panel is during the transportation and manufacturing of solar cells and also during the mining of the materials required to produce them.

3 – It Can Power Remote Locations

Solar power is ideal for providing a source of electricity in locations where it may be either impossible, impracticable or uneconomical to install a mains electricity supply. This can include remote locations, garden sheds and also various devices such as garden lighting. A prime example of this can be seen in space where highly advanced solar panels are used to provide a source of electricity for various satellites and also the international space station.

4 – It’s Renewable

Solar power is completely renewable. Although the sun does go down at night-time, it’s guaranteed to come up the next day. This process will occur for as long as life can be supported on earth and means that we’ll be able to benefit from the use of solar energy for the rest of our lifetimes unlike fossil fuels which are a non-renewable energy source and will eventually run out.

5 – There’s No Noise

Solar panels have the advantage that they produce no noise when generating electricity. This can make solar panels more attractive to home-owners who may have been considering a domestic wind turbine which would have produced significant noise pollution. Whether you opt for a solar panel or a wind turbine will however depend on the environment of where you live as these devices are suited to specific environmental conditions.

6 – There’s Little Maintenance

Solar panels require little maintenance. As there are no moving parts in a solar power system, there is little to go wrong with a system that has been installed professionally using the best quality components. The only frequent maintenance associated with solar panels is the annual cleaning of the panels themselves which can often be performed by the property owner depending where they are installed.

7 – Reduces Dependency on Fossil Fuels

Solar power helps to reduce our dependency on fossil fuels. As non-renewable fossil fuels will one day run out, we can at least install technologies today that help to prolong the life of fossil fuels. This can also help to provide energy security.


So there we have the advantages of solar power and the ways it can benefit our lives. Not only can it help to save us money, it is also a clean and renewable form of electricity that requires little maintenance and helps to reduce our dependency on fossil fuels.
