Free money (kind of)

Net Metering Available

Get paid for the extra solar you produce

Net metering policies in Hawaii can help solar panel owners save money and reduce their carbon footprint. When your solar panels generate more electricity than you use, you can send the excess back to the grid and receive credit on your next bill. Just something to keep in mind when considering solar panels.
