What are the Best Solar Panels on the Market?

The solar market is full of companies offering a wide array of solar panels of every type, quality and watt output, but which are best? With so many options, selecting the right solar panels for you and your home is getting harder by the day.

To get the best solar panels, you have to consider panel quality, longevity & power output vs. price to buy and install. Another important consideration is the manufacturer warranty, which can range between 20 to 30 years.

So what you really need to know is which brand should I go with? Well there are a few on the market that are comparable in quality and output. Below we have listed first the output then we go on to list what are widely considered the best or ‘tier 1’ brands of solar panels.

Most efficient solar panels available in Australia

The efficiency of a solar panel is determined by dividing the output by its size. High-efficiency panels produce the same output with fewer panels and take up less roof space. That being said, a 5 kWh system with high-efficiency panels will produce the same output as a 5 kWh system with standard panels.

Here is a list of solar panel companies with top efficiencies

Manufacturer Maximum Efficiency
SunPower 22.2%
LG 21.1%
Panasonic 20.3%
Solartech Universal 20.2%

What are the Best Solar Panels for Off-Grid Solar Systems?

Choosing an off-grid solar system is much more challenging than selecting a grid-connected system. You will need solar panels, battery bank, battery inverter, solar charge controllers and backup generator.

The most important consideration is the inverter which will handle the power spikes of your appliances. You can use any solar panel you want for off-grid application but make sure to have it performed by a professional. The high-efficiency solar panels can fit your bill or you can also go for the best brands we discussed.

Does it Matter Where Solar Panels are manufactured?

Some people put a preference on the country where the solar panels are manufactured. For example, many homeowners think that solar panels made in Germany or USA is superior to products made in China. But as it turns out, there is little correlation between the country of manufacturing and the quality of the solar panels.

You might be surprised to know that many companies in USA or Germany have production plants in Asia. And no single country dominates the solar panels market.

So what is the secret to choosing the best solar panel company?

First, you should consider all solar options and not just place your preference on a single country. Check out the product, research the reviews and find out how they perform.

Secondly, try to get as many quotes as possible to find the best price. Last but not the least, compare all your equipment options as big-scale companies may have fewer solar equipment options.

What Types of Solar Panels are best for Residential Solar?

Solar panels use three main type of technologies- monocrystalline, polycrystalline and amorphous thin film. Each has their share of pros and cons and the type that suits your household depends on factors like location, home orientation, solar inverter and more. Here’s a breakdown of the technologies to help you make an informed decision.


Monocrystalline panels offer good power-to-size ratio. You can expect an efficiency of up to 175 watts per meter square with exceptions. Some top brands offer conversion efficiency of 18%.

The panels are ideal for cooler conditions as they lose out on performance as temperature increases beyond 25-degree Celsius. You can expect a long lifespan and many products come with a 25-year warranty.

Contrary to popular belief, the panels may not be better than polycrystalline panels.

Polycrystalline panels need more surface area compared to monocrystalline panels for the same output. They can range in efficiency from 120 to 150 watts per meter square with notable exceptions.

They are suitable for hotter conditions due to lower heat diminishing coefficient. The panels have a long lifespan and warranties of 25 years. Polycrystalline panels may be less expensive than monocrystalline panels.

Amorphous Thin Film

Amorphous comes with a low conversion efficiency of about 60 to 80 watts per meter square. The panels can withstand higher temperatures of inland Australia but requires 2 to 3 times additional panels and surface area to produce outputs comparable to crystalline panels.

Amorphous panels have lower lifespan than crystalline panels but perform better in low light conditions.

What Type of Solar Panel Works Best in Cloudy Weather?

Solar panels produce energy on cloudy days but the output is lower compared to sunny days. Typically, a solar panel will produce 1/3 of its output on cloudy days.

But some technologies are more efficient in absorbing sunlight even in cloudy weather. Amorphous thin film solar panels are designed to absorb a wide spectrum of sunlight including infrared and UV light. The light waves are present on cloudy days even when there is no visible sunlight. They have better performance compared to crystalline panels and can produce more energy even in presence of cloud cover.

Black silicon solar panels are also ideal for cloudy days as they use nanotechnology to improve light absorption. Some companies like Trina Solar and Suntech have already started producing panels using the technology.

How do I Get the Best Deals on Solar Panels?

Getting the best deals on solar panels may be a bit challenging with so many options out there. First and foremost, don’t rely on price completely. You should also consider other factors like-

  • Efficiency of the panels (industry average of 15% to 18%)
  • Warranty of the product (industry average of 10 to 25 years)
  • Reliability and durability
  • Customer reviews, ratings and industry opinions
  • Cost to relative efficiency- the most efficient panels may not always offer the best value

After thorough research, the next step is to collect as many quotes as possible. Compare various quotes and go for the one which provides the best value and performance.
The best deal on solar panels doesn’t necessarily equate with cheap solar panels. So do your homework and choose a panel that offers value for money.
