This is really pleasing news to see E-ON taking Google's "Sunroof" online solar calculator tool to the European market. Initially the focus will be on Germany and hopefully the UK will following quickly afterwards. This news follows the recent announcement in the UK that they will be launching a new solar-plus-storage offering. It really seems that E-ON are committed to adapting their business model to offer solar services to their residential clients. Lets hope that the other major suppliers follow suit with similar offerings.
