How we rank and compare the best panels
- Product warranties
- Australian presence
Panel efficiencySolar panel efficiency is an indicator of the quality of the module and how it might perform throughout 25 years. It’s no coincidence that the most efficient solar panels also have the lowest level of degradation and perform well in adverse conditions. Efficiency isn’t everything, but more efficient panels will take up less of your roof space.
PerformanceMeasuring the performance of the actual module can be difficult as so many factors affect solar panel output. However, manufacturers must provide a guarantee of the performance of the panel after 25 years, based on laboratory tests. Typically, the performance ratio is around 80%, which indicates the level of degradation after 25 years. The best panels all have higher output ratios after 25 years, with top of the range brands achieving above 90%.
Solar panel warrantiesAnother important point of comparison is the solar panel product warranty; a manufacturer guarantees that your panel will continue working as it should. Do not confuse the performance warranty with the product warranty. Product warranties range from 10 to 25 years. If a company is prepared to provide a longer product warranty, it’s normally an indication that they are producing a higher quality panel.
Australian presenceAn important consideration when buying solar panels is whether or not the manufacturer has an office and representatives on the ground in Australia. Often this is an indication of their commitment to the Australian market; if they do not have an office Down Under, it will make warranty claims far more difficult.
Value for moneyThe final point of comparison is also the most subjective; value. Does the panel represent value for money? Value is very much a decision you need to make for yourself. We assess the value of the best panels if the quality outweighs the added solar panel cost; if it doesn’t, we factor that in too. Value is an important consideration, but ensuring you are buying a good quality panel that will not let you down is more important.
