Buying a residential or commercial solar panel can be an exhilarating experience. It would be best if you were happy about going green for Australians and saving more money.

But don’t take advertising too seriously. With the changing future of solar technologies, you also notice that more and more brands will compete for your money. To make an informed decision, you want to find the best solar panels in Australia.

How Do You Determine Which Solar System Is Right For You?

To choose the right solar energy system for your house, you need to have a good understanding and awareness of a few crucial elements connected to your home’s architecture.

It is necessary to have a comprehensive knowledge of your home’s roof before installing a solar energy system.

Before deciding on a residential solar panel installation, there are a few things you need to make sure of, including the following:

Solar Panel Size

The appropriate size and dimensions of the solar panels are the primary aspects of the system that require your attention.

All solar panels are recommended to be installed in a position facing north in Australia, which is located in the southern hemisphere.

Therefore, choose a dimension for your roof that satisfies this prerequisite.

You can place your residential solar panels to face either the west or the east, but you want to be sure they are in the best possible spot to maximise solar electricity.

The size of your panels must be compatible with the side of the roof on which the commercial solar installation will take place. You need to ensure that you have solar panel experts who can assist you in evaluating the severity of this issue.

The Coolness Provided By Your Roof

Because it will have less contact with the sun if your roof has any shading, the solar panel’s ability to generate electricity may be negatively impacted.

As a direct result of this, there will be a decrease in the amount of energy produced by solar panels. If you install a conventional solar panel and position it such that it receives some shade, then the entire system’s integrity is at risk.

On the other hand, there is absolutely no need for alarm.

You can go with half-cell technology if your roof is shaded in any way, whether entirely or partially, by nearby buildings, trees, or other items.

This technique allows solar panels not obstructed by anything to perform their jobs effectively.

Consequently, using this will enable you to benefit from sufficient solar energy for your household, even in environments with some degree of shadowing.

Solar Panel Efficiency

When shopping for solar panels in Australia, the aspect of panel efficiency should be given particular attention. The capacity of a solar panel to convert the energy it receives into the energy it produces is referred to as its efficiency.

Why should we care about this? Not only does a solar panel with a better efficiency have a higher output, but it also charges solar batteries at a faster rate.

If your system is more efficient, you will generate more power even when the sun is not shining quite as brightly. You would like to increase the amount of energy that your panels produce.

Therefore, how do you choose which panels will have the most efficiency?

The typical efficiency of the panels should be anywhere between 16 per cent.

Everything with an efficiency between 20 per cent is considered to be on the higher end, while everything with an efficiency of 20 per cent or more is regarded as the best.

Solar Panel Durability

Another essential consideration when purchasing solar panels is the panels’ durability. Investing in panels that are long-lasting can save you the headache of always having to replace worn-out components.

Because Australia is subject to occasional periods of high wind speeds, it is essential to have panel durability to prevent as much downtime as possible.

It would be best if you looked for solar panels that have a wind load that is relatively high and at least some level of protection against hail.

You want to have significant snow loads in addition to having high-quality solar panels because many of them do not require maintenance. Why?

A high snow load indicates that an object can sustain a certain amount of pressure and weight. It can withstand the same amount of debris being placed on it.

In addition, you should look for a solar panel resistant to the effects of the surrounding environment.

The Quality As Well As The Price Of The Panel

You also need to give careful consideration to the panel’s overall quality in addition to its price when making your selection for the ideal solar panel.

There is a wide selection of solar panels on the market, each with a unique set of characteristics and a range of prices.

Their qualities also differ from one another, which is why you need to purchase the solar panel in a very deliberate manner.

Warranty Periods

Buying solar panels with an extended warranty is also essential. You want a long-lasting solar panel warranty. Many panel manufacturers provide 9-10 year warranties.

Twelve-year warranties are becoming more prevalent, whereas 20-22 year warranties are rare.

Solar panel warranties are also important. A performance warranty guarantees that a manufacturer will find your panel faulty if it performs poorly.

Many manufacturers rank this at 82% of rated efficiency. Suppose your solar panels are 22% efficient and output 400W. It needs 20% efficiency and 320W peak power.

Replace anything less. Solar panels offer 28-year performance warranties.

How Do Solar Panels Power Homes?

After being created in the sun, photons travel the space between their and the earth’s surface in a matter of minutes. Photons are tiny energy packets.

The energy from the sun is subsequently converted into direct current (DC) by the photovoltaic cells, often known as PV, contained within your panels.

Solar panels are comprised of silicon cells that have been engineered to absorb photons and form connections with them.

When this occurs, electrons are dislodged from their atomic structures.

The photovoltaic effect causes conductive plates attached to the cells’ sides to assemble these electrons, after which you transfer them into the wiring. The result of this procedure is the formation of an electronic circuit.

Direct current (DC) electricity is made when electrons move through a circuit. You can store it in a power supply or turn it from DC to AC with an inverter. Both can be picked. Which is what most homes, businesses, and equipment choices.

Grid Connection And Solar Panels

In Australia, the majority of solar power systems are linked to the grid, which provides homes and businesses with electricity.

You are not required to use solar electricity exclusively if you have a grid connection. Off-grid technologies are more prevalent in rural areas without access to the grid.

Let’s say your building is already connected to the power grid. If so, you might be able to sell any excess electricity your solar panel system produces back to the grid in exchange for a feed-in tariff from the energy provider.

This can be deducted from the amount of electricity you use from the grid and applied as a credit to your power bill.

What Are The Things To Consider While Choosing A Solar Company?

Buying a solar power system for a home is exciting, but be careful when choosing a business. As a long-term investment, solar panels require careful consideration.

Several solar companies and retailers are operating in the market today; however, not all of these companies can be trusted.

There are some questionable businesses out there.

The following are some crucial points to consider when choosing a solar company to ensure you get the best solar company possible and keep potential problems at a distance.

Experience

A new solar company is starting up every other day. Choosing which firm is best for you is challenging. Many businesses lack the necessary skills in the field of solar energy.

Most often, these businesses aim to market defective, inexpensive equipment.

Regarding these businesses, you ought to use extreme caution. Customer feedback is crucial.

Check reviews from people who have used that solar company. A trustworthy organisation always posts client reviews online. Our website includes user reviews.

Price Check

Price is a significant consideration when picking a solar provider, but it should not be the decisive factor. As a result, some low-price organisations may be shady and will not offer you your desired solar system.

Your solar system quotation must include installation, servicing, connection, and maintenance costs.

A reputable and good company will give you a complete and detailed quote that includes how much electricity will be made and how much money you can expect to save.

Check Warranties

A good solar panel should last at least 14 years. So, only hire installers with a 20-year warranty. Include in warranties:

• Solar Panels – 25 years of operating performance and 12 years of artistry. Here, Open Electrical is offering 12 years of artistry.
• Artistry – 5 years as per CEC Approved Solar Retailers Code of Conduct.
• Inverter – 12-year warranty

FAQs

How Do You Judge The Quality Of Solar Panels?

A solar panel’s poor quality can be determined by whether or not it has a high-temperature coefficient.

The figure 0.7 per cent shows a wrong coefficient in terms of performance and therefore indicates solar equipment that is not particularly trustworthy. A reasonable value is within the range of 0.5 per cent, while the best solar panels fall to 0.3 per cent or below.

What Are The 3 Types Of Solar Panels?

Monocrystalline, polycrystalline and thin-film. Knowing the difference between the three is the first step to choosing the perfect panel for your home, company or community.

How Do I Choose Solar Panels In Australia?

Here are some of the factors you should weigh up in making your choice:

• Solar Panel Efficiency.
• Solar Panel Cost.
• PV Module Quality And Warranty.
• Manufacturing – Country Of Origin.
• Solar Panel Specifications.
• Aesthetics (How The Solar Panels Look)

How Many Kw Solar Do I Need?

According to our prior research and observations, a solar system with a capacity of one kilowatt (kW) is estimated to generate 1,200-kilowatt hours (kWh) annually in North Carolina.

Therefore, if the annual energy use of your home is 11,000 kWh, we would estimate that you need a solar system of around 9.4 kW to cover 99.9 per cent of your energy needs (11,000 divided by 1,200 equals 9.4).

How Many Solar Panels Do I Need Calculator Australia?

For every kilowatt, your solar array produces, you will need either three 330-watt panels or four 250-watt panels. If you are thinking of installing a 5 kW system, you would need between 18 solar panels, which will take anywhere from 25.5 to 34 square metres of an area on your roof.

Advantages And Disadvantages Of Solar Energy

Reduce expenses

You’ll probably be able to cut prices on your power bill or variable costs whether you utilise solar for all of your energy requirements or only a portion of them.

Lifespan

If properly maintained, good solar panels could last 18-21 years or maybe even more.

Different Ways To Use

Solar power may be use for anything, from making electricity to running satellites in space.

Renewable Solar

It can be used practically elsewhere in the country as a clean, plentiful, and renewable energy source.

Minimal Maintenance

Solar panel systems don’t have many moving parts, so they don’t get worn out as quickly. The inverter may be replaced every five to ten years as soon as possible, and different isolators and cables need maintenance.

Potential Drawbacks Or Disadvantages Include:

Initial Expense

However, prices are typically far lower than they were a few decades previously, and if incentives are utilised, they can further reduce costs.

The initial cost for solar panels may be substantial, particularly if you have a solar battery system.

Demands Space

Solar panels might not even be appropriate for homes with smaller roof spaces because they take up much space.

Weather Dependent

When it is raining or cloudy, less electricity is generated.

Number Of Solar Panels Require To Use

Consider your aims and conditions when selecting a system size: reducing your carbon footprint, increasing your ROI, saving money, and so on. Including the circumstances, energy you require, the size of your roof or floor surface, local sunlight, and the efficiency of your solar panels.

Solar panel system sizes are given in kW rather than panels. An average Australian household consumes 20 kWh per day, which is equivalent to a 5.2 kW system.

Each day, 1.2kW of solar panels generate 4 kWh. Divide your company’s or household’s electricity bill by five to get the capacity of your solar system.

When selecting a system size, consider your roof slope, wintertime, and cloudy days. This may necessitate additional panels or a more involved treatment.

Solar-battery

Surplus solar energy is stored in solar batteries for future use. Although they are not necessary, solar batteries can be useful. Extra solar power can be stored for use at midnight or in overcast, rainy conditions.

Solar batteries can be useful for off-grid houses. If you’re connected to the grid, you can store additional electricity you produce.

Depending on how your system is configured, you may only sell electricity to the grid when your battery is completely drained.

You can be disconnected from the grid thanks to a battery, giving you backup power in an outage. If you have a battery, you won’t be able to save money by sending extra electricity to the grid.

If your energy provider doesn’t provide feed-in tariffs or has high peak-use rates, a battery could help you save money.

Depending on needs at home or at work. 2.3 kWh to 12 kWh or more of usable storage can be provided by lithium-ion batteries such the Aquion Aspen, BYD B-Box RES, Tesla Powerwall 2, Arvio Sirius Capacitor Module, and Akasol neeoQube . Use of electricity is measured in kWh.

Inverter Solar

Solar inverters are an essential component of every solar panel installation since they convert the DC output of solar panels into the AC power used by the majority of devices and appliances.

Your solar system and inverter should have complementary capacities.

Therefore, if your solar system has a 5.2 kW capacity, your inverter should likewise have a 5.2 kW capacity; generally, inverters must be at least 82% as powerful as the solar power system.

Inverters are designed for installation outside. However, extreme heat shouldn’t be applied to them, since this will reduce their lifespan and hasten decomposition.

They should be installed by a qualified electrician in a shaded area of a wall that is typically close to your property’s main switchboard.

You’ll most likely have a hybrid, microinverter, or string type of inverter. No of the type, inverters eventually need to be replaced after 18 years because to wear and tear.

Using your inverter, you might be able to keep an eye on metrics like monthly average and daily yields. It can also be used to evaluate performance, keep track of battery charge, and confirm the solar system’s overall health.

When used in conjunction with a regular solar monitoring service offered by certified electricians, your inverter can help you effectively monitor and improve your solar panel system.

Conclusion

It’s crucial to select the appropriate choice for your home’s solar energy system. The main factors that need your attention are the proper size and dimensions of the solar panels.

In Australia, which is in the southern hemisphere, it is advised to put solar panels facing north. Efficiency is the ability of a solar panel to transform the energy it absorbs into the energy it produces.

A more effective solar panel produces more energy and charges solar batteries more quickly.

The panels should typically have an efficiency of between 16 and 20 percent. There is a large variety of solar panels available, each with a distinct set of features and a range of costs.

Additionally crucial is purchasing solar panels with an extended warranty.

An object can withstand a certain amount of weight and pressure if there is a large snow load on it. Most solar power installations in Australia are connected to the grid, which supplies electricity to households and businesses.

There are some dubious enterprises out there, and not all of these businesses can be trusted. When choosing a solar supplier, price is an important issue, but it shouldn’t be the deciding one. Hire installers with a 20-year warranty solely since a good solar panel should last at least 14 years.

Due to their size, solar panels might not be suitable for houses with smaller roof spaces. Prices are usually far lower than they were a few decades ago, though.

An average Australian household uses 20 kWh per day, or 5.2 kW, of energy. The capacity of your solar system can be calculated by multiplying the electricity cost for your business or home by 5. Off-grid homes may benefit from solar batteries. Every installation of solar panels must include inverters.

The majority of electronics and appliances use them to convert solar panels’ DC output into AC electricity. Your inverter can assist you in efficiently monitoring and enhancing your solar panel system when utilised in conjunction with a regular solar monitoring service.
