Solar Energy Storage

Say goodbye to power outages forever

Energy storage in the Virgin Islands is more affordable than ever! Technology advancements have made batteries smaller, more affordable, and relatively maintenance free. Combining your solar system with a battery will keep your house powered day and night, regardless of what is happening with the utility company.

“After 99 days without power from hurricane Irma we were limping along with a diesel generator.. it was a tedious and expensive way to live. The prospect of solar and battery backup was very appealing to us. Since the installation we have had many service outages; all of these were handled with little or no indication that the utility had gone down. This technology is without a doubt the wave of the future.”
– James & Mary D, December 2017; Tesla Powerwall owners

Solar + Storage

Caribbean Solar Company can create an off-grid or battery back-up system that produces and stores energy while maximizing comfort and savings. Most homes in the Virgin Islands can go off-grid with battery banks that fit in a small storage shed.

Our most recent installations include:

Hydrogen Fuel Cells

Hydrogen fuel cells are a great alternative to battery banks for larger scale off-grid energy systems in the Virgin Islands.

Hydrogen can be created from an electrolyser, which splits water molecules into hydrogen and oxygen. Generate power from only water and the sun for the ultimate green property.
