Some Misconceptions About Solar Panels


There are multiple misconceptions about solar panels circulated on the websites. Like, how much solar panels actually cost to the carbon footprint attributed to producing them. It’s misleading sometimes to know which information is valid and which isn’t.

So any further queries arriving in your mind, let’s plunge into the cost of solar panels and the certain different ways which can eventually help you to save your money in the future. Here, we will discuss the actual number of panels you will require for your home.

How Many Solar Panels are Actually Required to Power a House? 

Basically, the average number of homeowners needs around 28-34 solar panels so as to balance their electricity cost along with the price of the solar panels and the whole installation. 

These numbers are specified by considering the average household electricity use of about 10,400 kWh annually and the total amount of electricity capable of being generated by 250-watt panels.

To calculate the solar panel estimate, you just need to look at how many kilowatt-hours (kWh) you use as per in a year. Then, your monthly bill will showcase your total utility power consumption for the last twelve months.

For a better viewpoint, one kWh is equivalent to 1,000 watts of power that is in use for an hour. So, for example, if your home has 20 lights that all use 50-watt bulbs, having all of them on for an hour will use one kWh of electricity.

The total number of panels your home requires also depends on certain factors like panel performance level and panel’s location. The cost of solar panels also depends on the size of the installation job.

You just have to contact Future Solar WA and get your solar quote from our consultant. This will guide you to evaluate installation, panel prices and find what’s most suitable for your house.

We all know that solar prices in Australia have plunged over the last decade, especially if we look at the price for a larger system.

However, the price for a PV system in 2020 is laboriously financed thanks to the solar rebate scheme initiated by the Australian government. 

Below are mentioned a few approximate prices for solar systems after deducting the rebates.

Panel System Strength Number of Panels Approximate Cost
1.5kW 5 $2,500-4,000
3kW 10 $3,500-4,500
5kW 17 $4,500-8,000
6kW 20 $5,000-9,000
7kW 23 $6,500-10,000
8kW 27 $7,500-11,000

6 Myths About The Solar Panels

So then, there comes a common question: how much do solar panels actually cost? Now, the answer starts by focusing on the cost of installing solar panels first. 

Basically, it all depends on the amount of wattage you want to generate from your system and the size of your system. The initial investment of installing a system might be pricey. Nevertheless, the possibility for savings on your electricity bills explains this purchase significantly.

Solar Panels are Bit Expensive and Repay Themselves Very Slowly

This couldn’t be any outlying truth. Nowadays, there are considerable incentives, programs and schemes launched that help in reducing the initial cost of a solar system.

These often include state-run programs, nationwide schemes or several incentives. Luckily, there are some of these programs that also focus on battery storage, thus allowing you to save even more in the future.

Extra credits can vary as per the location. Depending on your state location, you can acquire extra incentives such as:

  • Property tax exemptions
  • Cashback
  • Waived fees
  • Expedited permits

Also, you will be eligible for a solar system rebate which is considered a small scale incentive by the Australian Federal Government. The rebate provides a discount on the solar power packages and their products.

If you wish to invest in a grid-connected solar power system, then you will receive full payback in 3-5 years. It all depends on factors such as solar PV system size and electricity usage.

Electricity Bill is Cheaper with a Solar Panel System

This is absolutely true. 

Here are the reasons why. It all depends on how you utilize the energy made out of your solar panels. If you maximize your solar system during the daytime, then it reduces your electricity requirements at night. 

For instance, if you are using your dishwashers or washing machines during the daytime instead of during the evening, then this will help in lowering the need for electricity at nighttime and will eventually contribute to reducing the grid-connected bills.  

Also, if your solar panel generates any excess energy which you don’t use during the day, then you can obtain a feed-in tariff. This is basically a credit on your bill that helps in reducing your electricity cost. 

Solar Panels Affect a Home’s Resale Value

This is not true and actually, you should not worry about it. Because the value of your home will probably go up in future.

There’s an increasing number of people shifting towards renewable energy and solar power fulfills this demand. The main reasons behind this shift are it’s clean renewable energy, affordable at the same time and will help to save your money in the long run.

Research depicts that 85% of Australians consider solar panels a value-add when it comes to property value.

Better than earlier, the solar PV system size affects how much value is added to the property later. So, the more panels you are installing, the more the property’s value increases in future aspects. If you are thinking about something that gives will give you an edge on the property market for the future, then no doubt solar panels can prove to be a good investment.

Because electricity prices are always expected to rise in the future, accessing and making solar power more advantageous.

Solar Panels Requires Lot of Care and Maintenance

This is maybe one of the greatest myths about the solar system that we hear. They are actually very much maintenance-free and are easy to take care of.

You just need to be secure about giving your system a simple dusting after every few months. Always clear out any dirt lying on the panels and remove any shade sources.

Likewise, most of the systems are designed to last for around 20 years and don’t require much maintenance as well. If your system is facing any kind of faults or efficiency issues, then firstly refer to its user manual and if it doesn’t work then just contact your installer for further advice.

After installation is done, set up an annual inspection so as to check your solar system and panels. Solar arrays are designed with durability and can also protect your roof from the elements.

Solar Panels Affect the Electricity Cost For Those Without Solar

Out of all the myths about solar panels, this is the shadiest one. It de-emphasizes many of the advantages of getting a solar panel system. For many Australian people, solar is the only way they consider reducing electricity costs. This has led to incredible growth in solar installations in the past few years.

This number often includes both homes and businesses, which actually shows the graph of how widespread solar has become in recent years. However, the fact is, solar installation is not possible for everyone and this is the main cause of some to believe that those who go without solar have to pay more.

But the truth is, the peak demand for electricity is gradually and thanks to solar energy from millions of businesses and homes with panels installed.

This is actually working as a bonus for the national grid supply. As the cities and their populations grow, the demand for electricity demands the need for more transmission lines, new thermal generators and several upgrades. The infrastructure costs eventually trickled down onto all electricity consumers.

The growth of solar panel systems on city rooftops is reducing the need for network expansions and large wired transmissions in cities. This is because there is plenty of solar energy, especially during summer days. This is particularly very much beneficial when the demand for electricity is very high.

Excess solar energy also reduces the need for installing expensive gas plants or power stations. 

Solar Panels Are Purposeless If You Don’t Use Power During the Day 

The fact is you will still stand to get benefits from solar power in many other ways. It all depends on how you optimize your consumption. You can save more on costs by using a battery storage system, solar feed-in tariffs or by using appliances on a particular-time basis.

Then, why not focus on using your free solar electricity during the daytime instead?

So, at night, you can find different ways to reduce your energy use such as:

  • Use a dryer, washing machine or dishwasher by setting on timers during the day.
  • Charging battery-powered appliances or devices during the day like phones, tablets, rechargeable vacuum cleaners.
  • Try to run the air conditioner on a timer during the day so as to cool or heat the home. 

The total amount of electricity you will use from the grid can be reduced by investing in a solar power system along with battery storage capabilities. This combination will help in generating enough electricity and thus counterbalance your day and night time energy use perfectly.

How Much Can We Actually Save With a Solar System?

While looking out for the best panel prices in the market, always consider the multiple variables first. Like, there are certain panels that have higher efficiency ratings than others, but it doesn’t mean that they result in higher savings also. 

One way to assure that you get the best deal is to evaluate quotes provided with varying financial offers and equipment.
