Advantages & Disadvantages of Solar Energy

Sep 23

As renewable energy sources become more popular, solar energy is emerging as one of the most promising options. This type of energy comes from the sun, and it can be used in a number of ways to power homes and businesses. Solar energy has both advantages and disadvantages, so it's important to understand them before deciding if this is the right choice for you. Let's take a closer look at solar energy and its pros and cons.


Advantages of Solar Energy

As the world becomes more and more industrialized, it's important to find ways to reduce our reliance on harmful fossil fuels. One of the cleanest, most sustainable sources of energy is solar power. Here are just a few of the advantages of using solar energy:


  • Source of Renewable Energy

The fact that solar energy is a completely renewable energy source is the most significant advantage of solar panels among all its other advantages. It is available every day and can be used everywhere in the world. Unlike some other energy sources, solar energy will never run out.

We will be able to access solar energy for as long as there is a sun, which means that we will have at least 5 billion years until the sun dies, as predicted by experts.


  • Lowers electricity costs

Your energy expenses will go down since you'll be able to use some of the electricity your solar system has produced to satisfy your demands. Depending on the size of the solar system and how much electricity or heat you use, you can save a variety of amounts on your utility bill.

For instance, if your company now uses commercial solar panels, switching to a larger system could significantly reduce your energy costs.

Additionally, under the Smart Export Guarantee, you may get paid for the excess energy that you export back to the grid in addition to saving money on your power bill (SEG). If your power production exceeds your use (considering that your solar panel system is connected to the grid).


  • A Variety of Uses

There are many uses for solar energy. You can produce heat or electricity (photovoltaics) (solar thermal). Solar energy can be used to distill water in locations with a shortage of clean water, generate electricity in places without access to the electrical grid, and run spacecraft in space.

Additionally, solar energy can be included in the construction materials. Sharp recently unveiled transparent solar energy windows.


  • Affordable Maintenance

In general, solar energy systems don't need much upkeep. They only need to be kept moderately clean, so a few times a year of cleaning will do. If you're unsure, you can always rely on specialized cleaning businesses, which provide this service for between £25 and £35 every visit.

Manufacturers of reliable solar panels typically provide a 20–25 year warranty.

Additionally, there is no wear and tear because there are no moving parts. Because it is constantly converting solar energy into power and heat, the inverter is typically the sole component that needs to be replaced after 5 to 10 years (solar PV vs. solar thermal). To guarantee that your solar power system operates as efficiently as possible, maintenance is required for the cables in addition to the inverter.

Therefore, after paying for the solar system's initial purchase, you can anticipate spending very little on upkeep and repairs.


  • Technological Advancement

The technology in the solar energy sector is always improving, and advancements will accelerate in the next years. Nanotechnology and quantum physics advancements have the potential to boost solar panel efficiency and double or even treble the electrical input of solar power systems.


Disadvantages of Solar Energy

Solar energy is lauded as a clean, renewable source of power. However, there are some significant disadvantages to solar energy that should be taken into account before making the switch. We'll take a look at some of the disadvantages of solar energy and explore why it might not be the best option for everyone.


  • Cost

Buying a solar system requires a significant up-front expense. This covers the cost of the wiring, installation, batteries, inverter, and solar panels. However, as solar technology is always improving, it is reasonable to predict that costs will decrease in the future.


  • Dependent on Weather

Even while solar energy can still be captured on an overcast and wet days, the solar system's effectiveness is reduced. Sunlight is necessary for solar panels to collect solar energy efficiently. As a result, a few days of overcast, wet weather can significantly affect the energy grid. Additionally, keep in mind that solar energy cannot be captured at night.

On the other hand, thermodynamic panels are an option to take into consideration if you also need your water heating solution to operate at night or during the winter.


  • The Cost of Solar Energy Storage

Solar energy must be used immediately unless it is stored in huge batteries. Off-grid solar systems that use these batteries can be charged throughout the day to utilize the energy at night. Although it is quite pricey, this is a good option for using solar energy continuously.

Most of the time, it makes more sense only to utilize solar power during the day and use grid power at night (you can only do this if your system is connected to the grid). Fortunately, since your energy needs are often higher during the day, solar energy can help you fulfill the majority of them.


  • Takes Up a Lot of Room

You will need additional solar panels to create more electricity since you want to capture as much sunshine as you can. Many roofs are too small to accommodate the quantity of solar PV panels you would like to have because solar PV panels take up a lot of space.

Installing part of the panels in your yard is a solution, but they must have access to sunshine. Installing fewer panels can still meet some of your energy needs if you don't have enough room for all the panels you want.


  • Connected to Pollution

Solar energy can be linked to pollution, despite the fact that it is much less than that caused by other energy sources. The generation of greenhouse gases has been linked to solar system installation and transportation.

Additionally, several dangerous and toxic substances are utilized in the production of solar photovoltaic systems, which may have an indirect negative impact on the environment.

However, compared to other alternative energy sources, solar energy produces a lot less pollution.
