Sun Cable: Cannon-Brookes wins battle for world’s biggest solar and battery project, page-80

I agree with that

I used to think that dust was a big problem with performance looking at the 'data' ---------- but, 2 things changed my mind. 1. I experimented myself and found that there was bugger all difference in a slightly dirty panel output ------


2. It's impossible to overlook the biggest most extreme solar panel experiment in history -

Opportunity and Spirit


how else can we say it ------------------------ solar panels work. They work under the most extreme conditions we can possibly throw at them
