Unfortunately, Wikipedia keep threatening to delete it. If one provides too much information they say it constitutes advertising, and if I provide too little, they say that more information is required to back it up.
'Solar charging' does already appear in google referring to plugging electric cars into solar powered charges. 'Solar earth charging' more correctly describes the activity of Charging the Earth.
If they do delete it, I shall just have to be patient and restore the entry in a year's time, when Wikipedia accept that such a thing can exist, once it has been running for a year and there have been some articles about it.
