How solar billing works in Curaçao
Exports and imports are priced separately, usually at different rates.
In Curaçao, rooftop solar appears to fall under a net-billing-style approach, where the energy you export and the energy you import are typically valued separately rather than simply cancelling out. Exports are often credited at a rate that may be lower than the retail price you pay for imported power, which generally rewards using your own generation as it is produced. The precise export and import prices vary by region and utility and change over time, so they should be confirmed locally.
