I've built a Mun-orbiting science station to process all the experiments that I've gathered from surface and space around. Basically this is simple final-stage rocket with four 3x2 solar panels attached symmetrically around the lab.
When I got to actual processing, to the enormously slow data processing per se, a lack of solar power generation is added. Batteries are not a bottleneck of this design, as they don't charge to the max during sunny-time.
My small question is how much electricity do I need to keep a science lab up and running with full data & 2 scientist sciencing on it?
My bigger question is how to optimally place solar panels & which (3x2 or 1x6 or just cover the fuel tank with 1x1 panels?) so that they could be conveniently deployed and get the most suntime i.e. maximize electricity per panel per day and provide enough of so needed electricity for the lab?
