Federal ITC 30% (tax credit)
State tax credit: Yes ($2,250)
Net metering (by utility)
There can be solar tax credits and incentives available at the federal, state and local levels. The calculator above will show you the value of all incentives your home is eligible for.
Electricity prices here in Hawaii remain the second highest in the nation, making it one of the most practical places to install solar. Innovative new on-bill repayment plans have been great at assisting low income residents to install their own solar energy systems.
How much money you can save with solar depends on which island you live on and how much electricity you use. Everyone in Hawaii can grab the US federal solar tax credit equal to 26% of the costs to go solar. It's important to note that Hawaii's state government also has your back if you’re considering going solar, with its own state solar tax credit.
Even without huge incentives or a perfect net metering program, the state is committed to achieving 100% renewable energy by 2045, and they're gonna need a lot of help from folks like you to do it. On the islands of Oahu, Maui, or Hawaii, HECO has a Quick Connect program to help you get solar panels installed quickly and boost the local economy.
Read on to learn about solar panel policy, incentives, and savings in Hawaii, and get ready to go solar!
Learn what solar incentives are available to Hawaii homeowners
See what Hawaii solar incentives you qualify for based on your utility company and city
Find out how much these incentives and/or Hawaii solar tax credits will reduce your cost to go solar and add batteries
The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in Hawaii
If you install your photovoltaic system before the end of 2032, the federal tax credit is 30% of the cost of your solar panel system. This is 30% off the entire cost of the system including equipment, labor, and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 30% = $6,000.
The federal tax credit falls to 26% starting in 2033.
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.
Hawaii no longer has net metering for solar owners. Instead, HECO has switched to giving homeowners a choice. In Hawaii, you can set up your solar panels under a system called "Customer Self Supply," which means you have to use all the solar energy to power your home (hello, batteries!) or "Customer Grid Supply," which means you send all your solar energy to HECO, and they pay you less than retail prices for it.
Finding out which system works best for you can be complicated, so make sure to connect with a solar expert near you to get help with this complicated decision.
Hawaii no longer has any cash rebate programs, but there are may other kinds of incentives available to help you save money when you go solar. Most importantly, Hawaii offers a sweet tax credit to its citizens that combines with the federal solar tax credit to wipe out a huge portion of the cost to buy solar panels.
Here's where Hawaii wins when it comes to solar. If you buy a solar system in the Aloha state, you'll see 35% of the cost (up to $2,250) come back as a credit at tax time, in addition to the federal tax credit of 26% (with no limit)!
When April 15th rolls around, an average 6kW system that costs just over $18,000 will net you an estimated $6,500 back from both credits, provided you have some tax appetite. Wow.
When you install a solar power system, your home appreciates by twenty times your annual electricity savings. When you add a solar power system, you add value to your home. How much value you add depends on how much money you save on your energy bill.
In a state like Hawaii, solar panels can save you a lot – more than anywhere else in the country, in fact. Normally, as you are all too aware, an increase in your home’s value means a corresponding increase in property taxes. Many, if not most states exempt you from those property taxes. Hawaii sadly lacks such a statewide law.
Don’t panic just yet though. The City and County of Honolulu has passed their own property tax exemption! No, that’s not the entire state, but it is about 70% of the people here in Hawaii.
If you’re one of those 70%, you’re already golden – you’re 100% exempted from property taxes associated with your new solar power system for 25 years. If you’re one of the unlucky 3 in 10, it sounds like we all need to get on the phone to the state capitol to tell them we want solar power tax exemptions!
If you’re a HECO customer making 140% or less of area median income, you can qualify for a special program called a Green Energy Market Securitization (GEMS) laon. The program grants you the ability to install solar for $0 down with a special loan you repay on your HECO electric bill automatically. Your system must provide enough power that even after your loan you have 10% savings over what you were paying previous to your solar installation.
There are no credit requirements, and the loan is not attached to your name, it’s attached to your electric meter instead!
In Honolulu city and county, you can get a 0% interest loan for a new roof and solar installation over a term of 10 or 20 years! The amount can be up to $60,000, here is the application information. Work with your installer to claim this amazing deal.

From start to finish this was an exceptional process. It was a throwback to a time when customer service was all about the customer. We were kept informed every step of the way, called if there was a delay for any reason, work was done timely, staff were more than competent and I was completely comfortable having them in and on my home. The work area was always cleaned before they left for the day. It was so refreshing to work with a company that does quality work, with quality products and cares about the client experience from start to finish.

Simply Superb! From the first contact with Jana in the office to the final steps with HECO this was an exceptional experience. Sean, our sales rep, immediately contacted us and listened to our needs and then after thoughtful review, and a prompt visit to the house, recommend the right setup for our needs. From there, the experience continued to get better. Clear, concise communication through the often times, slow and frustrating process of county and HECO approvals showed how they are clearly at the top of their game. Everything just clicked. Once approved, the next phase began. Once again, top class. Install date was set, prior to the install a tech came out and surveyed the property once again to make sure all details were to our liking and that they would arrive prepared for the install. That day came without a flaw. The Install manager was communicative, and effective! installation of 17 panels and a Tesla Battery were flawless, NO time was wasted & respect was shown for their presence in our space. They again, excelled at their part. Electrical installation came two days later, and after experiencing all of the above, I did not expect them to outshine themselves, but they did. The team was again, professional, courteous and simply did a stellar job at integrating the existing 34 panel system. the final install required some on the fly adjustments and creativity (our fault) and they were able to install a seamless and gorgeous install of all components needed on a single wall. Final inspections came and went without a hitch (of course) and the system is now cranking out sun power, enough to power the entire house and out cars (EV) with extra to spare, just a we requested. It is a thing of beauty, the feeling one gets when a) they harness the sun for all their power needs and more importantly b) they will never have to pay MECO another dime ;) Thank you for reading all of this, and please just know This IS the company to go with on MAUI. Bravo and our heartfelt thanks! Wynne Family

You will regret hiring Ryan Thompson and his company Prosolar. This was the worst contractor I have ever hired. Please read ALL previous reviews on all different sources to get a good idea of his MO. (This review serves both a sincere warning to others, but also a way for me to heal as a result of this nightmare). Once he gets his money from you, good luck on getting replies back, or completion of the process. You are no longer important. I promise, so prepare yourself. But it gets much worse. There were many red flags. He emailed me a bill for the electrical plan, which was to be included in total cost (which it was). He says it was a mistake. Today I question whether it was incompetence, or a deliberate attempt to gain from the unsuspecting. When he finally showed up to install panels. He didn’t have the right amount of panels. I reminded him of the math (x amount of kw = x amount of panels). He told he had to go back a get a couple of more panels. Once on site, the home owner is subjected to unrequested/unsolicited bizarre rants about anti-Covid vaccine, apocalypse, etc. You will be subjected to bizarre texts of his delusional thoughts of a ‘John Collins’, inappropriate partners with you while you are texting him, random pics of jam/other foods. If you call him in the evening he will be very angry and yell at you, while you want answers of why the solar app is showing no generation of power. At initial inspection time by the County, Ryan Thompson show more suspicious behavior as he had to arrive earlier than inspector to remove item. Then when inspector departed, he removed the new item and put his old item back on. Suspicious. BTW. He is not capable of articulating, so don’t bother asking him. He never showed up for the final Hawaii Electric inspection. Apparently he has a horrible reputation with them also. Inspector told me Ryan Thompson to several home owners to meet the inspector at a given time, not intending to show at any of them. He is the childhood bully in a man’s body. Beware.

Had two Tesla batteries installed. Cannot say enough good things about ProVision Solar! They took care of everything from design to permitting and installation. Support throughout was amazing. Houston and his crew were the most professional group of workers we’ve ever worked with. Would highly recommend ProVision Solar to anyone considering any type of solar installation!

I apologize this review is for the Big Island and since I can't get an acceptable response from them, I'll have to write my review on this site. Since May 2023, we have been paying on our solar loan, and we still have no solar panels. We signed the contract with Rising Sun in January 2023 with a planned installation of May/June 2023. It then slid to July/August 2023. It slid again to September 2023. Rising Sun has said the problem is scheduling. And it' sliding again. Our next step is to go to the attorney general and the BBB.

We`ve been priveleged to use RES, Inc before and find them extremely good. We`ve had solar for decades, first in CA, and service there was also good with the right company. We`re glad to recommend RES anytime to anyone.<br />We`re off the grid to tie-in questions are N/A. The gov`ts should give larger and easier to obtain incentives if solar is ever going to be as big as it should be. But look at the government we have now---they act clueless!
