This is the first challenge presented on the main [[solar]] page: How to manufacture enough solar panels without destroying the planet.

==Requirements==
Requirements are currently listed on the main [[solar]] page. {{x|I might move them to here instead - but for now, I don't want to have to keep the same content updated in 2 places.}}

==Candidates==
It might be possible to manufacture a solar panel made of mostly:
* Monocrystalline or polycrystalline silicon
* Aluminium-based internal wiring instead of copper
More research is needed.
