Solar Panel

 generates electricity when exposed to enough light.

Properties
Solar panels generate power while lit by a bright light from surface at day or lightonium. Note that when powered by sunlight that they stop generating power slightly before full night and only start generating power slightly after full night ends.

A wire must be connected to the lower-righthand corner of the cell to carry the electricity it generates.

Not enough sunlight at altitudes below 665 or submerged caverns to power Solar panels and require building them close to Lightonium.

In-Game Description
Produces electricity from sun light(1kW).
