Devotion of Maintenance on a Balanced System
Solar modules or arrays minimal savings decrease, as factored with winter months as a peak, cost less without maintenance puzzles. With no moving parts and a city grid they are necessarily solid state and won't break.
They usually work within the normal tolerance of electronic suitability. Stand alone photo-voltaic systems primary maintenance consideration can be added to the hefty cost of the solar cell. And though the temperature and sun angle varies batteries too can fail if they are unbalanced with the design.

Free form power collection must still rely on the survey of the sun's angle to the available surface area to collect the light. Tracking arrays on one or two axies still trickles more electrons, but where care was of a concern, it is a space consideration on the approximate order of 3 times the space without tracking arrays .
