Pros and Cons of Trina Solar

There is little to say about the possible drawbacks of Trina solar panels. Although some panels may have a higher manufacturing quality, they usually come with prices that are too high to make the purchase worthwhile. At the same time, while some panels may give you a higher efficiency level (and more watts per unit of surface), it is important to say that Trina comes at a lower price per Watt of installed power.
This is Trina’s biggest strength — its ability to provide a high-quality solar panel for both residential and commercial usage. Thanks to economies of scale, the company proudly stands as one of Australia’s leading solar panel suppliers.
