This is in answer to a question asked by several folks. We brought down 8 Concorde 6v AGM batteries (they're sealed, don't put out a gas so venting is not required and they can be shipped without a hazardous permit), 6 Solarworld 175 watt solar panels and all the stuff that goes with the system. This system cost us $13k US in March, 09. We also brought down a Sundanzer frig and Sundanzer freezer, Grundfos pump for the cistern and 7 DC ceiling fans. Of course, on top of that was shipping. We are extremely conservative with our consumption, but we couldn't be more thrilled with our system's performance. We're still going thru some adjustments, such as getting our marginally powered generator reconfigured to work as a backup. It's surprising tho' that we have been able to find folks who can help us get this all working.
This photo is showing our little setup, which is located in the bodega, just inside the door. We did have vent blocks installed at the top of the bodega walls to provide air flow.
My suggestion to anyone contemplating doing this is, buy as much wire, as many breakers (DC breakers are IMPOSSIBLE to find here) and any other bits and pieces you might need, in the US. Shopping here can be very frustrating and solar is still a new thing here. Lots of things not available and they can't answer many of your questions.
