I don't call "off-grid" a place with electricity going to it. 1 second logs since 2002 would be a lot of data. But go ahead, show us what you've got. I'll be able to see from the highs and lows how much clouds affect it. You have this weird "if you haven't done it or touched it, you don't know" << You clearly have not operated an "off grid" system. It would help you to have some real world experience. >> Without traveling at the speed of light, Albert Einstein figured out that E = mc2 and that the theory of relativity [General and Special] was how things work. Experiments and real world activities over following decades and centuries showed that he was right. When we did R&D in the oil industry, we hadn't done what was proposed. My job [in part] was to come up with ideas that had not been done. That's how CDMA was invented. First I came up with the idea. Then a gang forms to actually do it, then once it's real, people buy it, and then mobile Cyberspace becomes reality. You have the cart before the horse. Nobody can show me something that hasn't been invented yet. I don't have to see something that has been built to understand how it works. Do you know what "cart before the horse means"? What it means is the ideas come before the reality. First people who have the ability conceive of the thing they imagine, then they or somebody they tell actually builds the idea in actual materials. You think people have to see an actual photovoltaic installation to understand it. Or own one themselves. No. The horse pulls the cart Eric. The photovoltaic installation is the cart. The brain is the horse. BTW, I have another friend building photovoltaics if I want to see modern ones - he went in 2016 to live in Japan [with half Japanese wife and 2 sons] to build giant photovoltaic systems across east Asia. He's a civil engineer on the construction side of it. I guess he'd be able to provide me information on the nuts and bolts. But I'm accustomed to data and don't need to see actual nuts, real bolts and dinkum washers. He emailed me a few days ago to tell me he's finding learning japanese is hard work. He's French and he'd barely got his english up to speed and he was off to live in another language. Mqurice
