So certain i read quite a few years back that the pv panels on the market back then used so much oil to make and gave back so little that they weren't in truth very viable. Think thats changed a bit since then so who knows in 10 years we might have improved the panel ever further making it actually worth something
if you really want to knock back carbon emissions find a replacement for concrete that stuff is just terrible, concrete alone accounts for more than 5% of the global co2 emissions which is more than the aviation industry . Hence two dissertations on finding alternative materials such as earth packed car tyres and cross laminated timber panels both of which would provide very sustainable housing.
