So yes, we're very selective about the balance of system components that we use as a part of installing solar. So, that's anything from the cable we use to the conduit that we use. All the accessories that go into delivering an end solution. So, there's lots of parts. There's probably about 50 different parts inside a solar system. And we ensure that we use high quality all the way through those components.

So many of our competitors cut corners by using cheaper components at various stages in that installation process. What that ends up meaning is that that system while maybe the panels are of an okay standard and the inverter is of an okay standard, all the bits in the middle they've actually reduced the cost and cut corners. And that will mean that the system is very unlikely to last as long as the other components. What you'll see is perhaps potential for water leaks. Potential for safety issues on those systems. And certainly those other bits, like conduit and cable, are just as important in terms of the solar system as the major components, like panels and inverters.

The issues with using lower quality components really is risk. Solar systems are very high voltage, so they work in residences all the way up to 600 volts. And certainly, if it's not installed correctly there is a risk of fire. There is a risk of electric shock. Yeah, there's really no substitute for quality here. At the end of the day you get what you pay for. And it's important that when you're buying a system, that you consider you're putting it on your own roof for a very long period of time and that you want it to last that duration and not fail with in a few years.
