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:

Tesla Powerwall

Powerwall is a home battery that stores solar energy so
you can use it on demand and self-power your home to
reduce your reliance on grid electricity. In the event of a
grid outage, Powerwall automatically provides backup
power or easily integrates with solar to ensure your home
is powered 24/7.
