Create: Solar Powered

Texture and model change. Ponder tweaks. Temperature factor added (disabled by default). Altitude factor config adjustments (disabled by default). Default config energy generation was changed to 10 FE/t max from 12.5 FE/t. Solar panels will now emit particles when above 51% solar efficiency. Added off and on blockstates. Solar panels will now emit a redstone signal directly. Connectors from C&A no longer draw FE from any side, only from the bottom. Cables from other mods no longer visually connect from the sides and the top of the block (unintended behaivour, the cables didn't draw any power anyway).
