I dug down trying to get the actual paper and it appears it's a pre-print with only the abstract available (but maybe I wasn't looking in the right spot).
That being said, the quotes from the author were more to the point of it being a milestone that in the UK that Solar+Battery systems were now less expensive than gas/coal.
To my understanding, this is a milestone vs "raw" production numbers, which you're correct in saying have had solar as the cheapest option for years.
