Take a closer look.
The components of a panel need to be carefully considered before making a purchase. Even how a panel is soldered can mean all the difference in performance. Hand and manual soldering can partially severe power flow. Imperfections such as dust and fractures in the solder can reduce the output of each panel and significantly bridle the overall power generated at peak periods.
High grade glass provides greater resistance to hail. Antireflective glass means more light is let into the cell and thus more power is produced. Low grade glass can tarnish and gloss-over with time, reducing the modules output.
Module efficiency is another aspect that requires careful attention. An often overlooked anomaly can occur in transit called 'micro fractures.' Unseen by the naked eye, micro fractures can roadmap low grade imported panels. A fractured cell will cause a reduction in Panel output. The low watt panel means more panels are required to produce the same amount of power. More panels mean more space and more opportunity for inefficiencies.
High efficiency panels make the most of available roof-space. High output low size. Consider this especially if shading and the size of your roof are issues.
The frame of the panel is the bones that hold it all together and the cables are the arteries that pump the power to the inverter. Low grade structural elements are often vulnerable to extreme weather.
The practices of private companies are just that, private. In this industry, privately owned and operated companies have proven to be unstable. Publically traded companies provide full transparencies and tend to operate on a larger scale.
Why do Companies proudly promote the year they were established? Because with longevity comes permanence and peace of mind. So when you decide what equipment you want to use, take a moment to consider how long have they been manufacturing panels. As a rule of thumb, the time in which a manufacturer has been trading should exceed the length of their warranty.
Product warranty covers the integrity of the panel for the determined period of time. Naturally, solar panels are extremely low maintenance. With that considered, if an issue happens to arise, you want to know that the manufacturer and installer will be prepared to replace any panel at fault over a reasonable period of time.
Whilst being less important, the performance warranty also needs consideration.Legislation dictates that every panel sold in Australia must come with a twenty year performance warranty. This guarantees that if a panel is still running after twenty years, it will perform at 80% of its rated output. Manufacturers of quality panels acknowledge their responsibility to consumers and offer up to thirty years of coverage. A longer performance warranty indicates a greater confidence in the product.
Perhaps the look of the panel is of little importance to you, but considers prospective homebuyers. If you choose to sell down the track, buyers may be much more receptive to a more aesthetically pleasing panel and thus a more attractive home. High reflectivity panels sends light and its energy back into the atmosphere. Panels perform better when they are cool. So panels with lower average temperatures outperform panels that overheat in the Aussie summer.
