how long is a bit of string, it depends on the string and relativistic physics
for domestic pv 10 to 15 years has been the usual timescale
costs and energy prices(and inducements)have changes but that sort of timescale of half the expected working life seems reasonable
mobile and micro pv is priceless and often cheap if it is needed
lights, coms etc are easy, a washing machine, hot things or a server room are rather investment heavy
hot things might be better done differently, load matters, load timing vs harvest timing matters, that leads to grid or off grid, which leads to business type stuff as well as the techy aspects
this has reminded me to get the mobile stuff out of the bag and do basic fettling to keep it in good order.
5kg and a couple of hundred quid is a good deal for basics like lights, radio and phone coms and power hungry posh cameras as an off grid package pv rig
i can harvest and store a few days worth in a day unless using the camera for video and don't sit on the radio's on button too often
work out what loads you can do with pv and get a return time in your planned timescale might be a start.
can you take it with you is a consideration unless it is a long-term project
panels from a roof and a battery from inside should fit in a van pretty well,
a "contract" might not be so mobile |
