How to Choose the Best Solar Panel
Here are four factors to consider when comparing solar panels and picking the best for your property.
Module Efficiency
Efficiency is the share of sunlight a panel turns into electricity. Higher efficiency gets more power from the same roof area, which counts most on small or crowded roofs. On a large, open roof, the gap between two panels matters less to your total output.
Cell Count
Cell count mostly reflects a panel’s format and physical size rather than its quality, so read it alongside the wattage and dimensions. Two panels with different cell counts can produce similar power.
Panel Size on the Roof
Solar panel size decides how many panels fit each roof section, so a few centimetres can change the layout around vents and skylights.
Testing and Certification
IEC 61215 covers design and durability testing, and IEC 61730 covers safety. Also check for salt mist tests, which are relevant to homes near the coast, where salty air wears on materials faster.
Popular Solar Panel Comparisons
From Shortlist to Rooftop in Brisbane
Volteam handles solar panel installation in Brisbane for homes and businesses. Once you’ve chosen panels from the table, the same team turns that shortlist into a working system.
- A system between 6.6kW and 10kW suits most Brisbane homes, and commercial solar systems start at 20kW.
- Network approvals are arranged before any hardware is ordered, and any switchboard work an older home needs is done by the same team.
- One person takes your job from quote to sign-off, so nothing gets lost between the sales conversation and the roof.
- Licensed electricians who are CEC (Clean Energy Council) accredited do the work, with monitoring, maintenance, and repairs afterwards coming from Volteam’s workshop in Brisbane.
Frequently Asked Questions
What does Tier 1 mean for solar panels?
Tier 1 is a label for manufacturers ranked on financial strength and production scale, with the list coming from BloombergNEF. It describes the company behind the panel, not a quality test of each individual panel, so check the specs and warranty for the model you are considering.
Do solar panels perform well in Australian heat?
Yes, with a small drop in output as panel temperature rises. Spec sheets show this as a temperature coefficient, which is how much output falls for each degree of extra heat. Mounting panels with an air gap beneath them helps them shed heat, which suits Queensland summers.
What's the difference between a product warranty and a performance warranty?
A product warranty covers defects in the panel itself, while a performance warranty guarantees how much power the panel still produces over time. In the table, product warranties run from 12 to 25 years and performance warranties reach 30 years. Read both before you choose.
Are the best solar panels the ones with the highest wattage?
Not always, since wattage in the table runs from 420W to 450W and a higher-watt panel is often physically larger. What counts is the total output your roof space can hold, so compare wattage with dimensions and efficiency before settling on a panel for your home.
How long do solar panels last?
A quality panel commonly keeps generating for 25 years or longer. Over that time, an inverter is usually replaced once, and upkeep for the panels is an occasional clean and a check. Warranty terms differ by brand, and the warranty question above explains how they work.
Can I mix solar panel brands on one roof?
Installers avoid mixing different panels on the same string, which is a single circuit of panels wired in series, because the weakest panel limits output for the rest. When you extend an existing system, Volteam checks which new panels can be matched to what is already on the roof.
Which solar panel brands does Volteam install?
Volteam installs Trina, Jinko, Aiko, REC, LONGi, and Canadian Solar panels. All six brands appear in the comparison table above, so you can check wattage, efficiency, and warranty terms side by side before arranging a roof visit.
Do higher-wattage panels need a bigger inverter?
The inverter is sized to the whole array rather than to each panel. More watts across the roof can mean more inverter capacity is needed, so panel choice and inverter choice are best settled together. You can compare solar inverters in the same way.
