Caribbean Solar Capacity Vastly Underreported in Official Statistics
An analysis of customs data reveals that Caribbean nations have installed approximately 2.3 gigawatts of solar capacity between 2021 and 2024, roughly double what official power capacity reports indicate. Most of this solar growth consists of rooftop installations on homes and businesses that remain disconnected from central power grids, preventing surplus energy from being sold back to utilities. Regional analysts call for regulatory reforms to streamline solar connections to electrical systems and unlock renewable energy's potential as a cost-effective alternative to expensive imported fossil fuels that power over 90 percent of Caribbean electricity generation.
The discrepancy between installed and reported solar capacity stems largely from decentralized rooftop installations that operate independently rather than feeding power into regional electrical networks. Energy think tank Ember's customs data analysis revealed this gap by tracking solar panel imports from China—the world's leading manufacturer—against official capacity registrations, demonstrating a significant blind spot in how Caribbean nations measure their energy infrastructure. This measurement gap persists despite the region's acute vulnerability to energy costs, with island economies lacking domestic fossil fuel reserves and paying premium prices for imported oil and gas that currently generates over 90 percent of electricity supply.
Regulatory barriers significantly impede integration of these installations into centralized grids. In several Caribbean jurisdictions, utility companies retain gatekeeping authority over grid connections, effectively preventing independent solar producers from participating in electricity markets or selling excess generation back to networks. Analysts argue that independent regulatory bodies should oversee interconnection decisions to enable distributed solar resources to function as a coordinated energy system rather than isolated installations.
Removing grid-connection barriers could meaningfully reshape Caribbean energy economics by converting wasted residential and commercial solar production into tradeable electricity. Residents and businesses may reduce energy costs while utilities could diversify power sources away from volatile import-dependent fossil fuels. However, implementation requires substantial regulatory reform and potential utility restructuring—changes that may face institutional resistance despite their long-term economic benefits for island economies vulnerable to energy price volatility.
