If you search some of my posts a few years back, I tell about some of the history of photovoltaics in the DR. Richard Hansen took a few down there in 1984 and quite a bit has happened since. The focus has been on the rural population not connected to the grid, and invertors satisfy the connected. You can buy panels and components locally in a variety of locations and suppliers. Some have the capabilities to install and other just supply. Panels are even sold on Dykeman in Washington Heights. It is all a matter of $$$ (paying 10-20 years of electricity upfront, minus maintenance.) There are websites that help design the system depending on the need.
When you use photovoltaics and small wind turbines, EFFICIENCY must come first. Light bulbs, appliances, fans and refrigeration need to use DC or be very efficient if they are run through an invertor, otherwise the cost is prohibative.
Remote locations can present issues with theft. If there is a caretaker you can trust and does their job, the risk can be minimized. You have to worry more about theft of the batteries and invertor than people taking the panels off the roof. At least that was my experience.
