Installing Photovoltaic Solar Panels

For several years we have thought about having solar panels on the back roof of our house.
In late March we committed ourselves to having photovoltaic (PV) panels installed and we've now been given an installation date of early June. This assumes that the parts will be available. Inverters (which transform DC current generated by the sun falling on the panels to AC current exported to the mains) are in very short supply at the moment.
The company who'll be doing the work are RenEnergy of Blofield Heath, near Norwich (http://www.renenergy.co.uk/). We had our site visit last week and have been given a final quote for the work.
Hopefully we'll be able to generate up to twice as much electricity as we use over the course of a year.
