The wife and I recently had solar panels installed on our roof, an east-facing bank and a west-facing bank. Not a big rig, we don't have a very large house. Just enough for the 2 of us. The house and the solar 😀
It was turned on around midday on January 29, so it hasn't quite run for 2 weeks yet, yet it's about to clock over 100kg of coal saved, and 250kg of CO2 not released! I'm not even that interested in how much it's saving off our electricity bill, it impresses me because I'd be hard pressed to claim a carbon saving rate like that from using a bicycle and trains instead of driving for the same period! Even when I was still working and commuting 5 days a week!
