I have been an Electronics Design Engineer, Software Engineer and Farmer. Retrained many years ago as an NICEIC Electrician and in 2009 as an MCS PV installer. On my Farm I have 25KW of Solar PV, A micro Water Turbine 400W grid tied, and 2 Wind turbines. Our house is heated by diverted energy into storage radiators backed up by a woodburner linked into a heat store. We ran our cars on Cooking oil for many years but last year bit the bullet and now have two Zoe EV’s. I’m a Linux fan, and have all sorts of distro’s running however I can’t leave Rasberrys alone, and have 7 undertaking cctv, media servers, VPN’s and obviously energy monitoring!
