This article refers to the RedPower Solar Panel, which produces Blutricity. For IndustrialCraft's Solar Panel, please see Solar Panel (IndustrialCraft).
Solar Panels are used to produce Blutricity, RedPower's form of power, upon receiving direct sunlight and will only work during the day. A solar panel will not work if an opaque block is obstructing it from sunlight. Solar Panels must be connected to RedPower Machines with Blue Alloy Wire. Raw materials cost 5252 EMC plus smelt costs.
Blutricity travels through neighboring solar panels, so if one solar panel is adjacent to a Battery Box, other solar panels' power could travel through the initial solar panel to the Battery Box and still generate the same amount of power.
