In the last issue we covered the ‘Zero Energy Home’ in the US; this time we turn the focus of attention to wider matters, but still related to the installation of PV in communities around the world. As a glance through the news in any issue of PVB will show, the diversity of installations is quite remarkable. Not only for domestic and commercial use, but also along our transport networks — and now even to pump oil. PV is clearly moving ‘closer to home’. But the fragmented nature of what is essentially a bespoke business of installing PV is counter-productive. To fulfil its potential, maybe the industry needs more standardization.
