Genuine question. Have seen lots of videos of people putting just one or two solar panels in their garden, on a shed or even on a van and using tech called a grid-tie inverter to plum it into the mains electric. Its started to make me wonder if we should all do this. Just a few hundred watts each from a percentage of homes around the average town or city would surely make a dent into carbon, meaning less oil and gas were burnt.
Obviously there are people who cant afford the tech or the space, but from just looking online the inverter is a couple of hundred quid, a 2-300w solar panel is 150 quid each. Cables not much. Talking to an electrician friend most homes have fuses here that can take a maximum of 30-50amps (in and out), so if your set up is small its not going to blow the electrics out.
Thoughts?
Yes and even if it didn't if you lived in a good enough area for it it would also reduce your own utility bills which is nice - but of course the biggest polluters by far are things we can't even touch through individual action, like the military, oil drilling etc.
