The dream of converting to PV panels is on a scale with building your own power plant. You need to be aware of every detail of your system, load usage day and night, battery condition and state of charge, sky conditions, Amperes available from your panels, charge rate, wiring size and condition, etc.
Consider available roof space for PV panels, or tank of water. Avoid mounting valuable equipment in reach of thieves.
Make up various load scenarios, then decide what maximum burden your power system must handle, so that your equipment performs well under those conditions: loads running simultaneously, daytime loads, nighttime loads, etc.
Look into the recreational vehicle market to see what equipment is available for low VDC.
Consider which loads could be 12V (low VDC) versus high VAC.
