In May 2007, we installed a 4.725 kW array of PV cells. Over the last 4 years we have generated an average of 3,500 units of electricity - mostly in the summer months. From experience I know that I can only use about one third of this and export the rest to the grid. Until the advent of 'Fits' I had a contract with Scottish and Southern to pay me 28p/unit for export - now I'm paid a measly 9p for everything generated + 3p for export - not a good deal compared with newcomers in the field. It seems the Government punishes pioneers.
Global warming is the most important issue of our time - it affects water, energy and food supply
I live in an energy efficient house of timber frame construction (therefore no cavity wall insulation) and triple glazing - built to Swedish standards about 20 years ago.
I am passionate about using the energy of the sun - even in our less sunny climes - the 100th object in the British Museum's 'History of the World in 100 Objects' is a solared powered lamp
