It’s time to focus on solar PV quality issues

There are big challenges ahead for the solar industry as a result of issues around low quality and non genuine solar PV products.


I’m not so different from anyone else; I love a bargain too and so I can understand why consumers and solar importers are occasionally lured by low priced PV panels.

However, I can see big changes ahead for our industry as a result of some of the issues around low quality and non genuine products, some of which have made their way to Australia.

The Quality issue.

I’ve harped on about what true quality manufacturing means before, but I had a fascinating conversation with a highly experienced buyer of solar PV in China recently which really drove home the issue of quality.

Making a solar panel is a bit like making a cake; there is a recipe of materials and some steps to follow. The best ingredients make a better cake, but sometimes the result is subtle and sometimes more obvious.

In my recent conversation the sad reality hit home to me of where our industry has got to, in some cases.  It is literally possible to visit some solar manufacturers and get them to tweak the recipe by substituting lower quality materials. “You want a 10-15% lower price? Sure, we can substitute back sheets, use low grade or reject cells, non genuine connectors and lower grade glass. It will look the same and for the first year or two, perform almost the same as well.  We can put your brand on it too. Only a short warranty though.”

There are times, it could be argued, that using up otherwise wasted materials and producing functional solar panels at a price point that those with little income can afford sounds like a great idea.  In the world’s poorest nations, where the alternative is eye disease from kerosene lanterns, I could even support it.

However, in Australia, where we enjoy a very high living standard is it justifiable to save a few bucks, even a few hundred on a solar system? I would suggest not.

Unfortunately, in the race to to survive in Australia’s hyper competitive market a number of companies have resorted to this practice and the results of poor quality are starting to show.

Parallel importing

A related issue is how these solar panels make there way down here. I have recently spoken with a number of PV manufacturers who are very concerned; and taking and increasingly tough stance on parallel importing.

Technically, whether you get your solar panels through “official channels” of through someone who is having a clearance sales in a far flung country because they are overstocked  shouldn’t matter.

But it does matter for several reasons.

Firstly, there is a the quality/recipe issue. Solar panels that may have been made for a specific project or region (say) to a lower quality standard. Bringing this type of product in and selling it with 100% transparency might be acceptable but there are emerging examples of this happening with vendors trying to pass them off as high quality products when they are not of the same build quality.

This is deceitful, mis-representative and driven purely by greed; and has no place in an industry trying build consumer trust and loyalty.

The second issue around warranty is that a number of manufacturers now trace the origins of their product and specifically EXCLUDE parallel imports from warranty coverage.  Manufacturers build the cost of warranty support into their sales price differently in different regions based on many factors and although no one expects or wants failures, the accruals are built in to make sure support can be handled.

By bringing in products through un-official channels you run the risk of not having the same – if any – warranty conditions attached. Again, 100% transparency might be barely acceptable but emerging examples how that the temptation to mis represent is very high.

The bottom line on these issues is that you get what you pay for. I don’t see a single manufacturer of commodity solar panels making big (or any ?) profits so they cant reasonably be accused of gouging the price.

For goodness sake, use genuine supply channels, don’t substitute materials and if you hear of this kind of crap going on, report it!

    It’s time to start regulating what products can be used. Self regulation is always preferable, but we are spending public money by way of STC’s to subsidise rubbish product that will fail, usually a couple of years after the installer disappears. Whilst the consumer is out of pocket, the industry is the ultimate loser as public faith in the industry will evaporate. There is no place for bargain basement rubbish in a technically advanced product like solar PV.
