Module quality: a critical consideration

When installing off-grid solar PV systems that often last for a quarter of a century, quality and reliability are perhaps the two most two vital factors. But with a vast (and growing) portfolio on offer to the consumer, it can be difficult to make the right decision. PES asked Richard Lowe of Dulas to take
a look at the technologies on offer – and the merits of each. A great deal of research and experience goes into the selection of a preferred PV specification and manufacture based upon the organisation’s principles of delivering renewable energy solutions that perform over many years,  emain reliable and can stand the test of time. The three most  common forms of PV panels considered when specifying equipment for an installation are monocrystalline, polycrystalline and  amorphous or thin-film systems. Each has its own benefits, which can be summarised as follows:
