Solar in the base game is OP AF. This mod nerfs panels and accumulators down to about 1/4 of their previous value to incentivize using other power sources, without completely eliminating the use of panels as a mid-game green power source.
Panels and Accumulators were nerfed at the same rate, so this shouldn't change the ratios you need - just massively increase the number you need.
DEPRECATED - future updates will occur in ETHMOD
