#1 -  Renewable Energy > Technical Discussion: Solar Electric System - Photovoltaic > pv system for 500 square foot cabin.

I have a small remote (off grid for now, the telephone company just installed poles and strung wires) hunting cabin in the far north Maine woods. It is well insulated and includes a wall mounted propane monitor heat, propane stove, propane tank-less water heater (uses D cell batteries for spark) and propane frig. The electrical load are a few cfl lights, 19in lcd tv, blu-ray player, xbox, desk top computer with duel core and duel video cards with a printer and a 21 in lcd monitor, wireless DSL modem and cordless land line phone 1/2 hp water pump (pressured PEX plumbing system with a 30 gal pressure tank) and 1 ceiling fan.  I have a budget of 5,000 but less would be better. what would I prioritize?...I guess from reading the "learn" section of this site are the charge controller and inverter. can I grow the system with more batteries and solar panels as my budget gets replenished?  I would prefer a system that can last a day or two of cloudy days and be able to run with a generator if needed. I would prefer to pole mount the panels on the backyard. should I use a 12v or 24 v system?

Thank You,
