Solar panel efficiency: Finding the perfect fit for your Aussie home

Solar panel efficiency is essential when choosing solar panels for an Australian home. While most modern panels boast 19% and 23% conversion rates, aiming for higher efficiency can significantly impact your system’s output. Panels exceeding 21% convert more sunlight into electricity, meaning you need fewer panels to achieve your desired energy generation. This translates to space savings on your roof, potentially lower upfront costs, and a faster return on investment.

Choosing the best solar panels: with solid warranty

When investing in solar panels for your Australian home, prioritising quality and warranty goes hand-in-hand, making a thorough solar panel comparison essential. While sun-soaked savings are enticing, reliable panels and robust warranties ensure your investment thrives. 

Look for reputable manufacturers with strong product warranties, typically 10 to 25 years, covering defects in materials and workmanship. Equally important is the performance warranty, guaranteeing your panels maintain at least 80% of their initial power output for 25 years. 

Don’t be swayed by “lifetime” warranties, as they often have limited coverage and complex claims processes. Prioritise established installers offering their own installation warranties, safeguarding against faulty wiring or system issues. 

Remember, quality and warranty are not just about initial cost savings but about long-term peace of mind and a secure solar future for your Australian home.

Where it's made: Does the country of origin matter?

The “Made in…” label can be a weighty factor for Aussie shoppers. While supporting locals is admirable, it shouldn’t be the sole decision-maker. Consider quality, ethics, and environmental impact too. 

While some countries have reputations for high-quality manufacturing, like German engineering such as sonnen, judging solely on origin overlooks the nuances of the globalised marketplace. 

Yes, some Chinese brands have earned reputations for lower quality, but judging an entire nation’s manufacturing by a few is unfair. China boasts globally renowned companies like LONGi and GoodWe that produce excellent goods.

Ultimately, research is key. Look beyond labels, delve into brand values, assess quality through reviews and comparisons, and prioritise ethical and sustainable practices wherever they exist, local or international. 

Remember, quality can be found across the globe, and informed choices lead to responsible and satisfying purchases.

Solar panel specs: Don't be blinded by wattage

When choosing solar panels in Australia, understanding technical specifications goes beyond wattage. Two crucial specs to consider are temperature coefficient and power tolerance. 

The temperature coefficient indicates how much a panel’s power output drops with rising temperatures – crucial in Australia’s hot climate. Opt for panels with a lower negative coefficient (closer to 0) for better performance. 

Power tolerance, on the other hand, shows the potential variation in your panel’s actual power output compared to its advertised rating. Higher tolerance (usually around +/-5%) gives you more peace of mind about getting the energy you expect. Remember, while efficiency and wattage are important, these deeper specs ensure your panels perform optimally in our unique climate and deliver the power you need.

Solar style: Balancing beauty and efficiency down under

While solar panels’ environmental and financial benefits are undeniable, their visual impact shouldn’t be ignored in Australia’s sun-drenched landscape. Luckily, aesthetics are no longer an afterthought. Modern panels come in sleek all-black designs, minimising visual bulk, while options with silver or black frames cater to diverse architectural styles. 

Don’t forget that integrated solar roof tiles seamlessly blend into your home’s design. Beauty is subjective, so prioritise panels that complement your home’s character without compromising efficiency. After all, a solar system that looks good and generates clean energy is a win-win for both your wallet and the planet.

How to find the right solar panels for your home in Australia

Switching to solar energy is a smart move for homeowners looking to save money and reduce their carbon footprint. However, choosing the right PV panels can be a daunting task. With so many different sizes and wattages available, it can take time to know where to start. Here are a few factors to consider when making your decision:

Determine your energy needs

The first step in selecting the right solar panels for your home is to assess your energy needs. This involves reviewing your past electricity bills to determine your average monthly consumption, measured in kilowatt-hours (kWh). For instance, if your average monthly consumption is 1,000 kWh, you would require a solar panel system capable of generating at least 1,000 kWh of electricity monthly.

Consider the size of your roof

Roof size and orientation play a crucial role in solar panel selection. The size of your roof determines the number of panels you can accommodate, while the orientation affects energy generation efficiency. In Australia, north-facing panels are ideal, while south-facing panels are preferred in the Northern Hemisphere. East and west-facing panels can also produce a substantial amount of solar energy.

Choose the right wattage

The wattage of PV modules refers to the amount of power they can generate. It’s important to choose panels with the right wattage for your energy needs. If you have a large home with high energy consumption, you will need solar power with a higher wattage. However, if you have a small home with lower energy consumption, you may get by with a solar system with a lower wattage. Choose panels with the right wattage for your energy needs.

Consider your budget

You want to choose solar panels that provide good value for your money. However, you want to maintain quality for a higher price. Make sure to research the different types of panels and compare prices to find the best option for your budget.

Research solar panel brands

Not all panels are created equal. It’s important to research different solar panel brands and choose a reputable brand with a proven track record. Make sure there is a warranty and a high-efficiency rating to avoid excess solar energy.

Get quotes from multiple installers

Get quotes from at least three different solar installers before making a decision. This will help you get the best price for your solar system.

Ensuring your solar panels are compatible with your roof

Solar energy has become an increasingly popular way for homeowners to reduce their energy bills and environmental impact.

However, before you install solar panels, it’s essential to ensure they are compatible with your roof. This means considering factors like the angle, size, and orientation of your roof to determine the best placement and selection of different types.

Angle of the roof

The angle of your roof is an essential consideration when it comes to solar panel installation. Ideally, your roof should have a north-facing aspect, as this will provide the maximum exposure to the sun. However, not all roofs face north, and some may have an east or west-facing aspect. If your roof faces east or west, you may need to install additional panels to compensate for the reduced exposure to the sun. Solar panels should be installed in an area that receives direct sunlight for most of the day.

Size of the roof

The size of your roof is another critical factor to consider when installing solar panels in Australia. The more significant your roof, the more panels you can install, which will generate more electricity. 

However, if your roof is small, you may need to install fewer panels, or you may need to consider alternative options like ground-mounted panels.

Orientation of the roof

The orientation of your roof is also important when it comes to solar panel installation. The ideal orientation for solar panels is a roof that faces due north and has a pitch between 20 and 30 degrees.

However, if your roof has a different orientation, your solar panel installer may be able to adjust the angle of the panels to compensate for this.

solar panels installation

In Australia, there are several options for roof-mounted solar panel installations, including standard panels, thin-film panels, and building-integrated photovoltaics (BIPV). Standard panels are the most common type of panel, mounted on brackets fixed to the roof. Thin-film panels are lighter and more flexible than standard panels, making them suitable for roofs with irregular shapes or structures. BIPV panels are integrated into the roof, providing a more aesthetically pleasing look.

To ensure your panels are compatible with your roof, it’s essential to work with a qualified solar panel installer. They will be able to assess your roof’s angle, size, and orientation and recommend the best options for your specific needs. 

Additionally, they will be able to advise you on the best type of solar system to use, taking into account your budget, energy needs, and aesthetic preferences.

By taking into account factors like the angle, size, and orientation of your roof, you can determine the best placement and selection of solar panels. Working with a qualified solar panel installer is essential to ensure you get the most out of your solar energy system.

How to choose solar panels?

To find out the best solar panels available in Australia, you should know the different tiers manufacturers are categorised in that determine the quality of the panels they sell. 

In addition, we will also talk about the cost. This will give you a general idea to guide you in setting a budget for your solar system. 

3 tiers of solar panel quality

In addition to cost, when choosing the best solar panel for your installation, it’s important to consider its manufacture and materials used.

There are three tiers of manufacturer quality and Energy Matters only supplies PV panels from the first tier.

Tier 1 solar panels Australia

Tier 1 solar PV panel manufacturers represent the top 2% of the industry. They are vertically integrated, meaning they control the entire manufacturing process, invest heavily in research and development, use advanced robotic processes, and have over five years of experience. Tier 1 producers utilise the purest silicon to produce solar cells, resulting in longer-lasting and more efficient solar panels. 

REC Solar, LONGi, and SunPower are examples of Tier 1 manufacturers recommended by Energy Matters. However, not all companies claiming to be Tier 1 meet the same standards. Quality can vary greatly, so it’s important to conduct thorough due diligence when selecting solar panels for your needs.

Tier 2 solar panels Australia

Tier 2 includes companies who invest less in research and development, are reliant on both robotic and manual assembly on production lines and have often been in PV module manufacture for 2 – 5 years. These Tier 2 manufacturers can produce good panels at good prices, but it can be a hit and miss affair.

Tier 3 solar panels Australia

Tier 3 encompasses 90% of new solar PV manufacturers. These companies assemble panels only. They usually don’t manufacture their cells and don’t invest in research and development.

While often available at a cheaper price, Tier 3 manufacturers use human production lines for manual soldering of solar cells. This often isn’t the best approach as quality can vary from operator to operator and day to day. A Tier 3 solar panel in Australia may in the long run cost you much more in terms of reliability and electricity output.

Considering that not all module manufacturers are equal, the solar panel price is just one aspect to consider. There are various factors beyond solar panels cost that should influence your purchase decision.

Solar panel Australia shopping checklist

Points to consider when choosing the best PV panel brands in Australia today.
Efficiency:The efficiency of a solar panel refers to how much sunlight it converts into electricity. Panels with higher efficiency will generate more power, even in low-light conditions.
Warranty:A good warranty will protect you in case of defects or performance issues. Look for a warranty that covers at least 25 years.
Durability:The panels must withstand the harsh Australian climate, including extreme heat and UV radiation. Choose panels made from durable materials with a good track record of performance.
Price:It can range from a few hundred to several thousand dollars per panel. It’s important to find a balance between quality and affordability.
Brand reputation:Choose a reputable solar panel brand with a good track record of customer satisfaction.
Tolerance:This is the range a panel will either exceed or not meet its rated power. For example, a solar module you purchase may have a ‘nameplate’ wattage of 200W. However, due to quality control issues, the output in ideal conditions may in reality only be 195W. A positive tolerance rating means the module will not only generate 200 watts, but perhaps more under standard testing conditions.
Temperature co-efficient:The temperature co-efficient rating is important to determine the impact heat has on a solar panel’s operation after installation. The lower the percentage per degree Celsius, the better. The price of a module with low temperature co-efficiency can be a little more, but in Australia’s often hot conditions, a little extra cost can be worth it.
Conversion efficiency:The efficiency of how a panel converts light into electrical energy will determine how much power your system generates. If two photovoltaic panels cost the same, but one has a higher conversion efficiency, then that module provides the better value for money. That is assuming the claimed efficiencies are correct.
PID resistance:PID stands for potential-induced degradation. Caused by stray currents triggered by certain climate conditions, the phenomenon can cause substantial power loss. Good solar panels will display little or no PID.
LID resistance:LID stands for Light induced degradation. This process occurs in the first few months after solar panels are installed. While this stabilises after a period, it can reduce the amount of power the module produces. A good PV panel in Australia will have little or no LID.
Embodied energy:Another important aspect to look at is the embodied energy of the solar panel. That is how energy intensive the production of the panel was and how quickly it will have paid itself back by producing more energy. Consider this aspect an environmental cost.
Durability / Longevity / Warranty:When investing in solar panels, it’s crucial to consider the durability, longevity, and warranty coverage provided by the manufacturer. Opt for reputable brands like REC Solar that offer a 25-year performance warranty, ensuring your panels can withstand harsh weather conditions and deliver consistent performance for many years. A comprehensive warranty will protect your investment in case of any defects or issues, providing peace of mind and ensuring the long-term viability of your solar energy system. Additionally, selecting a well-established manufacturer and an authorised installer will guarantee prompt and effective warranty service if needed.
Size and watts capacity:Determining your energy needs is crucial in selecting the right panels for your home. PV modules are priced based on their wattage capacity, with higher-wattage panels costing more. The size of a PV panel is also influenced by its wattage and the type of solar cells used. Ensure your system size can power your appliances and fits within the available installation area. Carefully consider future expansion plans to avoid premature replacement of existing panels. North-facing roof space is valuable for panels, so consider plans when installing panels.
Types of solar cells used:There are 3 main types of solar cells: monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Monocrystalline silicon is the most efficient type of solar cell but is also the most expensive. Polycrystalline silicon is less efficient than monocrystalline silicon, but it is also less expensive. Amorphous silicon is the least efficient type of solar cell, but it is also the cheapest. The best type of solar cell for you will depend on your budget and needs.
Prioritising factors:When choosing solar panels in Australia, it’s important to prioritise your needs. For example, if you live in an area with high wind or snow, you may want to prioritise durability over efficiency. If you have a limited budget, you may need to prioritise price over efficiency. However, it’s important to remember that choosing lower quality solar panels may cost you more money in the long run.

In summary, these are the major points besides cost you should consider when buying solar panels in Australia.

  1. Consider how the module is manufactured and the materials used.
  2. Carefully research how the panels perform in real world situations. This includes positive tolerance, temperature co-efficient rating, PID and LID resistance, prioritise factors and efficiency.
  3. Compare the warranty details of the solar panels you are considering buying.
  4. Learn more about the company that manufactures the modules
