Solar Array Controller

The Solar Array Controller is a machine added by Environmental Tech. It is used to make the Solar Array multiblock, which can generate massive amounts of Redstone Flux from sunlight, and comes in 6 tiers.

Generation
RF production depends on the tier of the Solar Array, the Solar Cells that are used, as well as the current amount of sunlight the latter receive. This table gives the amount of RF generated per tick in plain sunlight assuming the array is not being obstructed:

The final amount of RF/t is calculated using the following formulas: Where:
 * $$RF/t = \left \lfloor cellGen \times validCells \times sunlight \right \rfloor$$
 * $$cellGen = \left \lfloor 128 \times 2^{tier - 1} \times min\left ( maxEfficiency, averageEfficiency \right ) \right \rfloor$$
 * RF/t is the final amount of RF generated per tick
 * cellGen is the amount of RF per tick each valid Solar Cell generates
 * validCells is the number of Solar Cells that can see the sky
 * sunlight is the amount of light coming from the sun, varying from 0 to 1 depending on weather and time of the day
 * maxEfficiency is the maximum efficiency that the Controller can support
 * averageEfficiency is the average efficiency of each valid Solar Cell
 * tier is the tier of the Controller

Both final RF/t production and RF generated by cells are rounded down to the nearest integer.

The maximum effiency of each Controller and efficiency of each Solar Cell are given below:
