Solar panels produce power when exposed to the sun. Having multiple solar panels is the best option for producing power efficiently and quickly. It is hard to make.You can make two different kinds;The normal Solar Panel and the advanced solar panel.The advanced Solar Panel's recipe is similar to the regular solar panel, however it uses an advanced wafer instead of a basic one and heavy aluminum wire instead of regular, it's a little more expensive to craft, but always generates maximum output during the day, as opposed to the normal solar panel that generates varying amounts depending on the sun's position
