It’s more than a hope. It’s performance guaranteed.

So if anything wrong, it can be fixed.  The critical period is the first 10 years. 

Since warranty covers up to 12 and some 25 years for inverter and pnel warranty is 25-30 years performance. 

So I think it is a calculated risk there la. Not to say it will never break down but the effect will not be that bad. 

But one thing can cause the problem u said. U have a bad neighbour throwing stones to your panels.  Crack all of them. Then yes your worse nightmare happens.
