The system that we're replacing today, the array had issues going forward. And we've been doing on-site monitoring for the customer. And in the last six months have found that the panels have degraded and having issues. So we were able to identify that on site. And then on our recommendations, we recommended our high quality panel, because the customer was actually shocked that they had to replace panels going forward. We gave them the option of using a higher quality product. So they've got peace of mind for the next 25 years.

In regards to their system. The old panels that were up on the roof, obviously had been installed for a fair number of years. Earth resistance has been down in the system. When we went to site and tested, we found that some of the panels had a zero output on them, and weren't performing to what they were meant to. So we discussed with the customer, in regards to replacing the system with something better quality. So he had a good system going forward. The panels that were on the roof were definitely dead. They had multiple issues and stuff like that. The best course of action going forward was to obviously remove those panels and replace them.

We have definitely found that there has been an increase in system replacements. This is mainly due to cheaper systems being installed or less quality workmanship. If it's going to fail, will be sort of after the three-year period. After that three years, with the Australian conditions you'll find that the systems are going to start to deteriorate fairly quickly after that point. The panel coming off, they decided to go a high quality system. Obviously, they've now realised that the system that they had on originally has failed. So when we provided them with the details going forward, it was probably a natural step that they were going to look at upgrading the system to a higher wattage sort of panel.
