First set she'd put on, was only a 1.5kW and they just had snail tracks right through them. A couple of the panels when we took them off and had a good close inspection on them, that they had just started to develop into micro cracks and started to burn through. It took some time where we'd done all the tests for her, and she had her, because she is so particular every day, since she'd had the system on she registered what it produced. And you could see just how it had deteriorated, in the period of time. Because the best that it had ever done, back when it was new, was doing about 12kWh, I think from memory and it got down to where she's getting about 6 kilowatt hours a day. It was just the quality of the, of the, the panels. They were just the cheap budget panel. Where they were a 270 watt and they just can't handle it. And, only a couple of weeks ago, I took off a 10 kilowatt system of the same panel and the whole 60 were the same. And, but this, this particular site that a lot of the panels have actually burned through the backing board as well. So they were in real bad shape, and they were only 10 years old, 10 years. So it's going to landfill.
I think at the end of the day that the whole experience just ground her down, and she said, no, she's had enough. And bite the bullet, take it off, and put a good system on. What we put on was, 18, 365 Watt. So it makes it a 6.5, optimises, which is for the high output panels. Yeah I think that the system worked out about $4,000 cheaper than what the original systems cost. So she's now got the rolls Royce of the rolls Royce. And knocking out 35 kilowatt hours a day, she's not using anywhere near that. She's very, very happy with the system.
How did micro cracks effect the performance of Jan's solar power system?
