What's Your Solar Potential? - RoofRay
This site allows you to calculate your return on investment for a solar array to produce electricity.
Unfortunately, the Google coordinates don't cover my area in the DR, but I suppose you could use southern Florida for a reasonable approximation.
The "bad news" is that I just calculated for a comparable location (in Key West, Florida) and it would take 23 years for an installation that costs US $56,000 to start to pay back. Unfortunately, not something I would even remotely consider.
