Electricity Savings Tips for Hawaii
Hawaii has by far the highest electricity rates in the US — nearly 3x the national average. This makes solar panels the single best investment a homeowner can make. Most systems pay for themselves in 3-4 years. Battery storage is essential since Hawaii has moved away from net metering to a self-supply model.
