A quadrant of a solar panel. You can multiply it as many times as you want, I did it 4x on the preview images.
The color scheme is universal, so it should fit most of the spacecraft models.

All models are named correctly and logically, and all sub models, which has textures applied are UV unwrapped (non-overlapping). Texture sizes are mainly 1K, since smaller parts have all their own texture, and the model should be viewed from a distance.
