After a lot of thought and some ummming and errring we've gone with a multi-stage alternative energy plan. Stage One is a fully grid interactive small Solar System designed to at least drop the power bills a tad. Later stages will include extra installations of solar and wind and ultimately non-grid interactive systems. But everybody's got to start somewhere and a few weeks ago - we started here!
It's rather nice to be able to wander past the inverter and hear it humming away during the day!
