Small solar electric or photovoltaic (PV) systems are currently gaining popularity in the public domain in several Caribbean islands including Barbados and Jamaica as a result of spiralling electricity cost in the region.

When considering the economics of investing in small solar electric systems it is necessary to look at both the capital cost and the long term operating cost.
