Solar street lights are raised light sources which are powered by generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a or during the night. Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night.

[pdf] The first were installed in 2009, and are not associated with storage. The installed capacity is 13 MW, in particular via the Longoni power plant, inaugurated in 2010. Solar energy is the only renewable energy with significant development potential on the island; the wind potential (22 MW according to a study) would not lead to a significant production because the wind blows only 6 months per year.
