One of Barbados’ main rum producers is making one of the single largest solar power investments in that industry but he is not satisfied with the inordinate amount of time it takes to be hooked up to the national grid.Owner of the Foursquare Rum Distillery Sir David Seale disclosed on Thursday that he has invested about $10 million in solar photovoltaic systems on several of his buildings in an effort to slash costs, at the same time helping to propel the island’s energy goals.So far, the warehouse and three of the ageing bonds at his Foursquare, St Philip operation and the People’s Market in St Michael have all been connected to the national grid and are already cutting electricity costs and bringing in earnings.However, he disclosed, two roofs at his Hopefield home and four at the Foursquare operation that are outfitted with systems are still waiting to be connected to the grid.
