A few years back I bought a photo-voltaic solar panel, a deep-cell 12V battery, and an 800 watt inverter to use as a portable power supply and for emergency use.

Anyway, I started using it to power my room yesterday & went a little bit off-grid.
This is a basic most-simple system, but it is easily added to both by adding more panels-which reduces battery charge time- and by adding batteries which extends the run time.
My idea here is to recruit y'all to invest in such a system, discuss your experiences, debate merits of equipment, and actually
do something green.
I'm off then to find prices & availability of the basic 3 components. ........
