The Solar Panel is the first LV-tier power source of the Ala Industrial mod, generating Energy Units under the open daytime sky at a base rate of 1 EU per tick (1/20 of a second). A Solar Panel stores up to 8000 EU in an internal buffer and releases up to 20 EU/t onto a low-voltage line, sitting just below the 32 EU/t LV ceiling. Ala Industrial pairs the Solar Panel with a Copper Cable and a Battery Box to start the whole energy chain. The flat glass-topped slab works only in the Overworld, by day, when no rain or thunderstorm blocks the sky; glass or snow above the panel does not stop generation, but leaves cut the output to roughly 0.5 EU/t.
A Solar Panel is shaped like a half-slab with hardness 5.0 and blast resistance 6.0, mined with a pickaxe, and stacked to 64. The Solar Panel is crafted from 3 glass blocks, 2 redstone dust, 1 electronic circuit, 2 iron ingots, and 1 copper cable in a shaped redstone-category grid. A Solar Panel produces power only and never accepts input, so the top working face must stay uncovered while the 4 sides and the bottom emit energy. An alignment chip dropped into the single slot of a Solar Panel drives a roughly 3-in-game-day evolution into a stronger day-only Daylight variant or a night-only Moonlit variant, keeping the stored EU and the custom name.
