However, this measure comes with a significant limitation: the lack of batteries to store the generated electricity, which means that solar energy can only be used in real-time, during the day, without the possibility of meeting nighttime demand, when consumption is at its highest. On Saturday, Cuba initiated the installation of solar energy storage batteries at four electrical substations, marking a significant step in addressing its energy challenges. This effort, which involves establishing approximately fifty photovoltaic parks across the nation, aims to address Cuba's persistent energy. The energy crisis continues unabated in Cuba, and those with portable power stations now have an advantage, allowing them to withstand daily blackouts averaging more than 10 hours. But here's the kicker – less than 15% have proper energy storage systems. "We're basically throwing away.
