Great idea the product is ok but I haven't worked with it enough that it was handy to leave it on the battery it really charges I'm not sure about the Diode When there's no sun I need to find out if it drains my battery at night so for now it's a great idea and I intend to keep it and I wouldn't discourage anyone from getting it but I would go with this one App be conservative and make sure it works well before you leave it alone.
