12 Advantages & 8 Disadvantages Of Solar Panels

Table Of Contents


Well, it’s safe to say that solar panels have blown up over the past few decades. They have become soooo popular with homeowners, businesses and now even the governments are recognising their value.

But we’re all asking the same question … Why?

What’s so good about solar panels?
Why are they so popular?
Should I be getting solar panels? Or is this just one big hype?
Are they really worth the money?

Well, the short answer is yes. They are worth it, and I’m going to explain to you exactly why.

However, we cannot forget the law of balance. For every advantage there is probably a disadvantage. With this case, it’s true. You may not think it, but solar panels do come with their fair share of disadvantages.

So let’s jump straight in, and find out the advantages and disadvantages (pros and cons) of solar panels.

What are solar panels used for?

Government and big business corporations are also one of the biggest users of solar panels to generate clean, renewable energy. Businesses will use solar panels to slash the cost of their operation bills and free up cash flow to re-invest in their business.

Governments around the world are taking a big step with solar energy and it is being used to power trains, buses and even the international space station.

advantages for solar being used in space

For homeowners, the need to have solar panels has become increasingly more popular over the years. This is because solar panels can be used to generate electricity at home.

People are catching on about the endless benefits of rooftop solar. It’s exciting to see how popular it has become over the years. 

This electricity can then be used to power your electrical appliances in your home. Solar can power anything electrical, from your TV or fridge to your iphone or game console.

Essentially homeowners can become less dependent on the grid. At the same time you can save a significant amount of money on power bills each month. 

The different types of solar...

Different types of solar panels and systems can also be used to heat water. Thermal solar is a greener alternative to gas boilers and heaters.

Photovoltaic solar is used to power everything else that’s electrical. Because of this, solar is extremely versatile. It can be used in deserts, homes or even on top of city buildings or transport.

There are also a variety of solar panels that perform differently. Some may have micro inverters meaning each solar panel generates its own current and energy. Others may require an inverter for the entire string system.

store the power you generate from solar panels

Any power that is generated by solar panels can also be stored using solar batteries.

These can work for both homeowners and businesses and can be scaled up. Storing power can allow complete independence from the grid, meaning you solely create and use your own power.

Solar batteries are also becoming more affordable, as well as more popular for people or businesses who use most of their power at night. Also more and more solar battery rebates are becoming available as well. 

Why are solar panels so popular?

Over the past 20 years solar panels have become extremely popular with homeowners, business and the agricultural industry.

There are many different reasons why people are interested in solar but we have narrowed them down to 3 main reasons


Firstly, the most common reason why solar is popular is because of money.

Solar panels can provide homeowners with a massive saving toward their energy bill (if not completely reduce it altogether).

When people catch wind of their neighbors slashing their energy bill in half, they simply want a piece of the pie. By having a reduced energy bill it means that you will free up your cash flow each month to spend on stuff that you like or your family.

The finance side of solar is the main reason why it has become so popular in today’s age.


The second most popular reason is because of the environment.

Solar panels are being installed to help take a stance against climate change. People are willing to invest their money into something that will not pollute the planet we live on. Installing solar panels will help by generating clean energy that can also be sold.

This is much better than burning fossil fuels and oils which has a negative effect on the planet. We are realising the sustainability of solar panels which is making them more popular. 

Government Incentives

Thirdly, solar panels are getting a name for themselves through government incentives.

It is pretty hard to resist when the government is offering to buy back any excess solar energy you produce…

Plus lets not forget the massive reduction in the upfront cost, an interest free loan to help reduce the cost even more and then a STC certificate that can be sold for money!

Even with commercial solar for businesses there are rebates and grants being offered as incentives to help with the move to solar.

What makes solar panels worth it?

So, what actually makes solar panels worth it?

    • In places like Australia & America the sun is shining more often than not. This means we can capitalise on harvesting the sun’s rays to generate our own power. Having this endless supply of UV light definitely makes getting solar panels worth it. 
    • Government loans and rebates help with the upfront cost, and make solar extremely affordable for homeowners on any income. 
    • Latest technology in solar panel efficiency means that solar panels are designed to get the most out of the sun. This means you can really take advantage of producing your own energy knowing that you are getting the best performance. It also makes solar more affordable because you can produce more energy for a longer period of time. Brands like SolarEdge are leading in technology of solar panels.  


1. Reduce the cost of your energy bill

The most widely known advantage of solar panels is that they will reduce the cost of your electricity bills.

By producing your own power through the sun you will ultimately be buying less power from the grid. This allows you to spend less money buying energy which leads to saving more money on your power bills.

Due to the sun’s energy being renewable and free it means that you will not be paying for the energy you generate through your solar panels.

There are endless benefits that come from having spare cash each month to spend on your family or other things. Saving money is one of the biggest advantages of solar. 

2. Renewable Energy Source

Solar power is a renewable source of energy. Renewable energy is a source of power that cannot be used up.

Essentially the sun is generating a mass amount of power all the time that can be harvested by your solar panels without running out.

The plus side of solar being renewable means that everyone can take advantage of free energy given by the sun.

We wouldn’t have to worry about the sun’s power running out, but instead we can enjoy the rays that hit our solar panels and generate free, clean energy.

Being a renewable source solar power is also clean energy meaning the energy doesn’t produce any greenhouse gasses emissions.

3. Increase your property value

Because solar panels have so many benefits for homeowners, installing them on your property will increase its value.

Houses that have solar panels will be more valuable than those that do not.

This is because one home will be highly dependent on the grid whereas the other will be generating its own energy. Enjoying being free from the shackles of increasing energy prices.

Again this is because solar panels do have a high upfront cost and can be seen as a great investment asset. 

The money that you spend on solar panels will be invested into your home as well, you may even see a high return on investment from installing solar at your property.

4. Environmentally friendly

Energy that is produced by solar panels is clean, renewable and has zero-emissions. Solar energy does not contribute towards greenhouse gasses or fossil fuels unlike other oils and coals.

Essentially this means that solar panels are environmentally friendly products and will not harm the planet.

Being environmentally friendly means a lot nowadays, and you can gain popularity within communities for taking a stance against climate change.

It is one of the most popular reasons why people take a move towards solar, and is definitely one of the biggest advantages of solar panels.

Homeowners can rest easy knowing their energy is not harming the planet.

5. Wide range of solar products

Another massive advantage of solar panels is the huge range of different solar panel products available.

There are solar panels that are built for performance for those people who are looking for a high-end system to perform for a long time.

For homeowners who are looking for a good budget system then there is a massive range to be browsed from as well.

Thermal solar panels are also available for people who spend most of their energy on heating and want to use solar to help lower the cost.

Solar panels can be purchased with an all-in-one battery system for homeowners who need to store their power to use at night instead.

Having this wide variety of options comes as a massive advantage for homeowners as they can get solar panels specific to their requirements and needs. 

6. Low maintenance costs

With new technology being readily available, the maintenance of solar panels are becoming easier and easier.

Warranties are also being included for massive periods of time making the maintenance of solar panels less and less.

This is great because it means homeowners can buy solar without having to fix or check the system every week. Also, low maintenance means low cost.

You won’t need to spend anything extra on your solar panels system to keep it working at optimum.

Once in a while it’s recommended to get your solar panels cleaned if they have collected any soil or dust.

7. Homeowners can become energy independent

The installation of solar panels to your home could allow you to become completely energy independent.

With a good enough system, you could generate enough energy to power your home without having to buy power from the grid.

Not only is this a great accomplishment, but it also means homeowners won’t have to face rising electricity prices again.

Generating your own power will be save you a large amount of money. You also would not be affected if there was a power cut or any maintenance by the grid on their power lines.

Many people who have become energy independent can say that it’s a massive advantage of solar panels. 

8. Excess solar can be sold to the grid

Any excess energy that is not used in your home can be sold to the grid for extra cash.

Not only this, you are providing your local community with clean, renewable energy. This helps you and your community have cleaner energy supplied to your grid by pulling energy from the sun. 

Some homeowners will purposely upgrade their systems just to sell excess energy back to the grid.

The government offers some really good Feed-In Tariffs available for homeowners to get rewarded for any excess power they don’t use.

These tariffs usually vary from state to state. The two main tariffs are fixed rate and time varying. The price per KW is decided by these two tariffs, and is a great way to help pay off your system quicker.

Once the system is paid off you will see the return on investment from your solar panels. Solar panels could actually generate you free money, which is a massive advantage.

9. Return on investment

Solar panels are a really good investment to make, and homeowners will be able to get the money they invested back within time.

Although solar panels have a high upfront investment cost, the money that gets saved each month on power bills will help toward paying off that cost of the system.

An easy way to look at it would be: If you saved a large sum of money on your energy bill, then you can put that money towards covering the cost of your system.

Once the solar system is paid off you will still be saving money on your energy bills. Therefore, you are now making a return from the initial investment made on your solar panels. 

10. Get rewarded by the government

Government rebates are a great advantage of solar panels.

Being able to sell your energy back to the government for cash is enticing for homeowners to make the move to solar. With pressures on governments to move towards greener solutions, all future rewards are looking bright.

Rates may start to become more profitable and rebates becoming easier to get. However, this may not last forever. 

Although these rebates differ from state to state they all offer a big reduction in the cost and most will also offer a no interest loan scheme.

These government incentives actually make solar energy more affordable. This is a step in the right direction and helps first time buyers secure solar. 

11. Power can be stored and used at night

Some all-in-one systems come with solar batteries included like enphase. These solar systems let you store power you generate during the day and use it at night instead.

This would benefit homeowners that use a majority of power at night. Similar to commercial businesses like supermarkets or schools.

When you store power you become independent from the grid. Rather than buy energy, you can use the energy that has been stored.

This could provide even further savings for homeowners. It’s best invested with high end solar panels to see the full benefits of solar battery storage.

High end solar panels tend to have a higher performance and generate more energy, meaning you can store more power quicker.

12. Solar panels have Long lasting warranties

Companies that design, test and manufacturer and solar panels include long lasting warranties with their products.

This shows that they have a lot of confidence in the performance of solar panels and that they are guaranteed to reach a minimum performance for a period of time.

Long lasting warranties are a big benefit of solar panels because they show that they won’t break or stop performance within the first 10+ years installing them. Companies like Jinko, LG and SunPower offer great warranties. 

Homeowners can feel like moving to solar is less risky, because they are covered by the solar panels warranties.

It also means they can work out their estimated saving given that there are no issues with the solar panels. 


1. High upfront cost

The first initial investment for solar panel installation is quite high, and not everybody will be able to afford them.

Unfortunately this is a downside to solar panels however the future is bright as prices are coming down.

Solar panels right now are fairly expensive, however with new government schemes and the latest technology the price is becoming more and more affordable.

2. The size of system is dependent on your available space

Available space is a big factor in solar panel installation. If your roof is not big enough, then it means that you may have to downsize your system or rethink about getting solar altogether.

Solar panels are still fairly large products meaning they require a big space to be installed. The size disadvantage means that they cannot be placed into small areas, and actually require a large roof.

Some systems however do provide flexible designs for smaller roofs. 

3. Requires sunny weather to work best

Energy can only be generated when sunlight is hitting the face of the panel and being converted. Therefore if there is no sun, there will be no energy being produced.

Although solar panels can still generate power on cloudy days (as it’s the UV light that generates the energy) they perform best on sunny days.

Your solar panel performance will be negatively affected if there is not enough sunlight hitting the panels on rainy days.

4. Manufacturing of solar panels can harm the environment

Although solar panels produce clean, renewable energy, the process it takes to manufacture them can harm the environment.

Mass production of solar panels may result in fossil fuels being burned and plastic waste.

This does become a disadvantage for solar panels although they themselves produce green, renewable energy. 

5. Low energy conversion rate

Even the most advanced solar panels still only convert around 20-25% of the sun’s energy into power. It goes to show how much opportunity there is to develop better technology to optimise the full force of the sun.

However, there are many things that need to be considered like the direction of the panels and location. 

Jinko solar panels have claimed the world record a few times. 

6. Cannot be used at night

No energy can be produced by your solar panels at night which essentially means your solar panels can only generate energy 12 hours of a full day. Without any sunlight hitting the solar panels then there will be no energy produced.

This is a disadvantage of solar panels but may be something that is overcome in the future with new technology. There are already talks about an ‘anti solar panel’ that is able to produce power at night.

7. Solar panels are fixed at their installed location

Panels that are installed on your roof are pretty much installed there for good.

Unless you are looking to pay extra to have your system dismantled, de-wired and transported to another location then solar panels are stuck in one position.

Solar systems are not mobile at all, which means if you purchase solar but decide to sell you will have to leave your system behind.

8. Government rebates may not be there forever

Incentives and rebates provided by the government may not actually last forever. This is another good reason to take advantage of these rebates and incentives right now.

Due to the price of solar panels becoming more affordable, there may come a time in the future where the government reduces the rebates and incentives that they offer.

It’s best to jump on the wagon now to take advantage before they’re gone! 

Other factors to take into consideration

Solar is becoming increasingly more popular and common

Incentives and rebates provided by the government may not actually last forever. This is another good reason to take advantage of these rebates and incentives right now.

Due to the price of solar panels becoming more affordable, there may come a time in the future where the government reduces the rebates and incentives that they offer.

It’s best to jump on the wagon now to take advantage before they’re gone! 

The future of solar panels and solar energy is very bright

The future of solar is really bright, it’s being used in all aspects of the world. NASA is using it for space exploration or solar farms to produce mass energy.

Australia is using solar for transport, solar farms and now homeowners are taking advantage to slash their energy bills. 

It was actually annouced in 2020 by the International Energy Agency that solar power is the cheapest form of electricity. 


So there you have it. 12 pros of solar panels and 8 cons. 

Personally, I would still say there are more advantages for solar panels than disadvantages. 

However is saying this, it makes you realise that maybe they are not as amazing as everyone says. 

Although, I do admit I own a solar panel system and its the best investment I’ve ever made. I would choose solar panels over no solar panels any day!

  1. Hi Luke : Your Article is very detailed, extremely helpful to me. I have a question : I can’t make up my mind to choose between :
    1. SunRun package with LG 350 W panels, Delta Inverter and LG Chem battery or
    2. Elevation Energy Service package with Panasonic 360 W, Enphase Inverter, Tesla Powerwall battery
    For almost the same price, SunRun offers me more attractive incentives ( $1000 Referal fees, Visa card rewards, rewards using Costco credit card …. than the other one with only $1000 rebate.
    I greatly appreciate if you could analyze the quality, durability, functionality of different products from the 2 above solar companies ?

  2. One area you did not cover in the disadvantages is the cost and disposal of the panels after they are worn out.
    There are nasty chemicals that should prohibit the dumping of the panels.
    Bad for the environment, bad for drinking water, etc. The US does not have plan as of today for the disposal of the panels.

  3. Another story on how great solar tell this to some one living in high rise and can t get it.tell this to someone who is on a low income and can,t afford it,tell this to a renter I am very much in favour of huge solar farms that feed into the grid and everyone benefits this roof top stuff only benefits a few not all.

    1. What extra house insurance cost are there for storm damage.? 10 year Warranty are rubbish for a fairly simple device compared to a 7 or 10 year warranty for a car! Electricity Grid operaters are against residential solar panel electricity producers! They are about to charge people for there connection to the grid.

  4. David Patterson

    We had 30 Solar panels installed on our roof the end of October 2020 in southwest Indiana, with two Inverters. So far we have not paid for any electricity charges. We do get hit with a $15.00 meter charge. Any excess power we produce goes back to the grid. I currently have almost 2000 kWH credits going into the summer months. I have been told you make more power in the Spring and Fall months. We are thrilled with our system and wish we had done this sooner. We pay pretty high rates for electricity in this area, with taxes it averages to 0.16 cents per one kWH.

  5. Ofcourse solar power is worth it! Solar power is fed into the home to be used as it is generated, so by using solar power, you are not buying power from the grid.

  6. Very fantastic article. Agreed with your 5th point in the disadvantages that solar panels still only convert around 20-25% of the sun’s energy into power. Keep up the good work!

  7. Agreed with you. The first initial investment for solar panel installation is quite high but solar panels can give energy about 25-30 years lifespan which is also a good advantage. It’s worth investing.

  8. Palappan Murugan

    Very nice article and informative .The author should address the issues of the maintenance of the solar system in his next article as the life of the system is expected to be around 25 to 30 years .

  9. Nice Blog. Solar energy is the cleanest and renewable form of free energy available to us. So, Using Solar Panels is really great way to protect our environment.
