Solar Panel

Solar panels are a great source of energy units (EU) early on, and are still useful in end game. Solar panels generate 1 EU per tick if the solar panel has an unobstucted view of the sun. They are crafted as shown:

C | G | C

G | C | G

E | M | E

(Without Greg tech) C= coal dust G= glass E= electronic circuit M= generator

Note: Solar panels don't work underwater, in the Nether, or in the End.
