How much solar energy does Honolulu produce?
Honolulu has about 840.88 watts of solar capacity per capita, with over 7,700 existing solar installations.* About 97% of all buildings in Honolulu are solar-viable, which could produce 2.6 million megawatt-hours each year.* (A megawatt is one million watts, and a megawatt-hour is the output of that energy for one hour.)
What are the advantages of going solar in Honolulu?
By going solar in Honolulu, you can save significantly. Hawaii is notorious for its high residential electricity rate of 37.34¢ per kilowatt-hour, or kWh, of output (a Kilowatt is 1,000 watts), which is 214% more than the national average.* Though Honolulu’s electricity rates, at 35.1¢ per kWh, are 6% less than the state’s, you can save more each month by installing solar panels and generating your own power.
Solar systems are also environmentally friendly because the electricity they produce create no air, land, or water pollution. Residents can reduce their carbon footprint and positively impact climate change by harvesting the sun’s energy.

How much does solar cost in Honolulu?
The cost of a home solar system can vary, even in the same city, due to a range of factors. These include:
Solar panel quality
Roof size, shape, and condition
To help you understand the price of going solar in your area, we’ve analyzed SunPower price quotes, as well as quotes gathered by third-party sources,* for thousands of homeowners across the country.
In Honolulu, we found that the average investment to own a 5 kW solar system costs $15,200, or, in other words, $3.44 per watt—and that’s before considering the benefits of any available tax credits or incentives.
A measure of energy output, a kWh (kilowatt-hour) is 1,000 watts (a kilowatt) producing energy for one hour. The average U.S. household uses just over 900 kWh per month.*
Honolulu takes solar power seriously, which is why the state and local governments offer incentives and programs to help residents go solar. For example, the state has the Renewable Energy Technologies Income Tax Credit (RETITC), which gives residents a 35% tax incentive for solar systems under 5 kW.
Honolulu residents can also take advantage of the City and County of Honolulu - Real Property Tax Exemption for Alternative Energy Improvements incentive. The program gives new solar system owners 100% property tax exemption for 25 years.* A median-value home’s value can increase by up to 4% with a solar panel installation, making these systems a long-term investment that pays off.*
You can also reduce the cost of going solar by claim the federal solar tax credit when you file your income taxes. Also called the Investment Tax Credit (ITC), the benefit will give you 26% of the cost of a solar system.
Tax credits and incentives are subject to change. Visit dsireusa.org for detailed solar policy information.
