Solar panels are as close to being “sustainable” as is reasonably practicable: the frames are made from aluminium (which is made with electricity), the rest is glass, silicon and copper, all of which are potentially produceable without fossil fuels.

Steel and concrete are both more of an issue (steel is made using coal as an ingredient, but can potentially be made with hydrogen instead) and cement requires lots of energy and emits a lot of CO2 during manufacturing.
