Nice info to have, but the article appears to be a puff piece for Tesla panels, for which I assume the author is a dealer or installer. The author uses the table at the top to calculate the average W/s.f. output, BUT does NOT include the marginally better Tesla panels in that table, keeping the table''s average output calculation value lower.
