HomeAs a US territory, USVI homeowners get the same Federal Solar Tax Credit (Section 25D) as residents of California or Florida — 30% off the entire system cost. Combined with WAPA's expensive rates and frequent outages, this delivers some of the fastest solar payback in the entire Caribbean.
Federal ITC 30% tax credit calculator
Under the US Inflation Reduction Act (Section 25D), USVI residents get a 30% federal income tax credit on solar systems. Applies through 2032. Rolls forward if your tax liability is less than the credit. Same benefit as Puerto Rico and US mainland — no other Caribbean territory gets this.
The WAPA reality: solar isn't optional anymore
Virgin Islands Water and Power Authority rates are among the highest in the United States. Combined with frequent outages still felt years after Hurricane Maria, solar + battery storage isn't just savings — it's grid-failure insurance.
WAPA service reality
A typical 4-bedroom USVI home pays $400-$700/month to WAPA. With a 10kW + 20kWh Sunchees solar system priced around $16,000 gross / ~$11,200 net (after 30% ITC), that bill drops to grid fixed charges only.
Post-Maria hurricane-hardened specs
Hurricane Maria (2017) and Hurricane Irma (2017) hit the USVI within two weeks of each other, destroying tens of thousands of rooftop systems. Generic Caribbean mounting failed islandwide. Sunchees uses post-Maria building code as our minimum spec for USVI orders.
Generic Caribbean spec (other suppliers)
- L-foot at every panel corner
- 4 attachment points per panel
- 1/4" stainless lag bolts
- Standard rail spacing
- Generic IP54 inverter
- No additional roof reinforcement
Sunchees USVI Hurricane-Hardened spec
- Through-bolted mid-clamps + end-clamps
- 6 attachment points per panel
- 5/16" through-bolts into rafter (not just sheathing)
- 15% reduced rail spacing for 165 mph rating
- IP66 inverter in vented enclosure
- Roof reinforcement plates at attachment points

What matters for solar in the USVI
UL-listed equipment is required
USVI follows US standards. Permits and ITC claims require UL-listed inverters and panels. Sunchees ships UL-listed for USVI specifically.
Voltage: 120/240V split-phase, 60Hz (US)
Same as US mainland and Puerto Rico. Standard split-phase inverter. Easy parts replacement and integration.
Hurricane: post-Maria building code
USVI Building Code requires high wind rating for solar mounting. Sunchees USVI kits exceed this with engineering stamps.
Net Metering: WAPA program available
WAPA offers net metering for residential and commercial customers. Application via WAPA. Sunchees provides technical documentation packet.
