The client in question has developed a portfolio of patented wind turbines which extract significantly more power from the wind than conventional turbines. One of their products, the Remote Power Unit (RPU) is a hybrid solar and wind solution which has been designed as a street light. The off-grid RPU powers an 80-watt LED bulb with built-in battery storage lasting up to five days. The installation on Grenada is the first renewable hybrid streetlight on the island.
