CIS solar charging-correct list?

[Stan. SWAN]

Scott: Thanks for this solar net one info, which (as an electronic
guru) impresses me. Are those PV arrays 600 Watts?? Yikes- allow
~US$3k for these alone (about the annual salary for a teacher in many
downtrodden areas). Double this for the battery bank! Maintenance?

IMHO such a solar scheme is pipe dream stuff for subsistence lifestyle
regions that can hardly stretch to a litre of kerosine for lights, &
even just a single one may be orders of magnitude more costly than
schools & villages in the PNG/Solomon Islands region can justify...
