Solar panels alone do not solve the Caribbean energy problem. The sun goes down at 6 PM. Demand peaks in the evening. Without storage, the island still needs diesel generators running after dark.
Battery storage is what turns solar from a daytime supplement into a real alternative. Store surplus energy during peak sun hours, deploy it when the grid needs it most.
Battery costs have dropped over 80% in the last decade. What was financially impossible in 2015 is now competitive with diesel generation in most Caribbean markets.
Solar plus storage is not the future for the Caribbean. It is the present. The question is how fast islands adopt it.
