SunPower
4.4
Our Rating
SunPower is one of the largest and most experienced national solar companies in the country. It’s best known for offering some of the most efficient solar panels with industry-leading warranty coverage. Although it’s on the expensive side, the value provided is outstanding. It only serves cities on Oahu, including Pearl City, Mililani, and Waipahu.
SunPower is on the expensive side when it comes to installing solar energy solutions, but most customers agree that the value included in the high-quality residential PV panels is well worth the cost. Many people also note that the PV system pays for itself more quickly in many cases than less efficient brands.
The average cost for solar panels in Hawaii is around $2.70 per watt, but SunPower averages around $3.15 per watt. It’s more costly than most other companies, and the average 6,000-kW system in HI will cost around $14,000 after the federal investment tax credit (ITC) is considered.
SunPower is expensive, but many homeowners find that the warranty coverage offered is well worth the investment. This company provides protection for the equipment, workmanship, and solar panel energy production for 25 years. It also includes protection for roof leak coverage, and while this isn’t generally needed in Hawaii given the minimal rainfall — at least on Oahu, where SunPower has a foothold — it’s still nice to have.
SunPower is a full-service solar installer. It can install solar panels, solar battery solutions, and electric vehicle (EV) chargers, and it can provide solar monitoring.
SunPower’s high cost is more easily dealt with than it is with many other companies because it accepts all financing options, including PPAs, solar leases, solar loans, and cash purchases.
SunPower offers a referral bonus of $100 per person you refer for business. This isn’t much, but it’s a nice incentive if you have friends and family looking to go solar as well.
In years past, SunPower has managed manufacturing and outsourced all installation work to third parties. Now, SunPower is beginning the process of taking over the installation using an in-house team, and its sister company, Maxeon, is handling manufacturing.
The one major downside of SunPower is that it only installs Maxeon solar panels, which are expensive.
SunPower’s installers are certified by the North American Board of Certified Energy Practitioners (NABCEP). The company is also accredited by the BBB.

Factors to Consider When Choosing The Best Solar Company in Hawaii
If you’re not sure that one of the companies above is right for you, you should be equipped to continue on to carry out your own research. We’ve evaluated solar companies in HI based on a number of criteria, and you should do the same if you plan to look for an off-list provider. In the following sections, we’ll include information and tips on what to look for when assessing solar providers in Hawaii on your own.
Avoid solar panel scams by educating yourself on common underhanded tactics and how to identify them.

Cost of Services & Installation
First, you’ll want to look at the cost of the solar electric system you plan to have installed with the provider you’re considering. System cost can vary wildly between companies because of different labor costs and the quality of equipment each vendor carries. It’s best to find the highest quality equipment that can fit your budget.
Check out our detailed review of solar panel pricing.
Equipment and Damages Warranty
Solar solutions are expensive, and although the weather in Hawaii usually isn’t extreme enough to cause damage to panels, having warranties is always a good thing. Solar warranties can cover equipment damage and malfunction, guarantee a certain level of energy production, or protect you from faulty solar panel installation services. The best warranties cover all three, as well as roof leak protection (check out dependable home warranty for roofs). Most areas in Hawaii receive below the national average amount of rain, but a warranty covering the roof penetration is still great to have.
Solar Services Offered
All solar companies will install solar panels, but if you want batteries as well, some companies won’t be able to serve you. The more add-on products and services you want — like EV chargers, energy audits, and system monitoring — the more companies you can rule out based on the services offered. Some companies also offer additional products, like solar hot water heaters and energy-efficient water systems to make your home more energy-efficient overall.
It’s worth noting that Hawaii is particularly susceptible to power outages because of the constant load on the outdated electric equipment. Most homeowners choose companies that can couple panels with solar batteries like the Tesla Powerwall (explore our evaluation of Tesla Powerwall) to provide power through frequent outages.
Financing Options
Most people choose to pay for their solar panels with cash or with a solar loan, but others who don’t need long-term savings and instead want low or no upfront costs might prefer a solar lease or power purchase agreement (PPA). You can sometimes rule out companies and narrow your search based on what payment options are offered.
Do They Contract Installation
Some companies outsource the installation of their solar equipment to third-party installers, which can create issues with communication and customer service but tends to keep prices low. Others handle everything in-house, which costs more but usually leads to a more enjoyable and straightforward customer experience. You’ll have to choose which option suits your needs best.
Brands of Solar Equipment Offered
Not all solar panels and solar equipment are made equal, and not all solar panel companies carry all the brands you might want. If you decide you want high performing solar panels to take advantage of the plentiful sunlight or the cheapest solar panels, for example, you might have to rule out all of the companies that don’t offer that option. Keep in mind that the brand you choose can affect your upfront costs, your long-term savings, and how much you’re able to offset your electric bills.
Average Online Rating and Customer Reviews
The solar industry in Hawaii is booming thanks to the high cost of energy, which makes solar panels a worthwhile investment for most residents in the Aloha State. Where there is high demand, there will naturally be companies popping up to take advantage. That’s why it’s crucial that you read through a company’s reviews and online ratings before agreeing to service. Check positive and negative reviews to get an idea of the service the company provides and how likely your needs are to be met.
Industry Partnerships
For similar reasons, it’s good to look for industry affiliations and certifications to verify the validity of a company and gauge its commitment to the industry and renewable energy rather than just profit. Some things to look out for include accreditation by the SEIA, NABCEP-certified installers, and business accreditation by the BBB.
Size of Company
Finally, we recommend you consider the size of the company and determine if it’s a good fit for you. Larger companies will naturally have less appealing customer service, but they’re often more flexible with consultations and installation timelines, and they’re usually cheaper. Smaller companies provide better customer service in most cases, but they tend to be a bit more expensive.
FAQs About Solar Power in Hawaii
Who is the most reputable solar installation company in Hawaii?
In our opinion, Rising Sun Solar is the most reputable solar installer in Hawaii. This company has many years of local experience, it only handles best-in-class equipment, and it offers great warranty coverage, all at an affordable price. Best of all, it provides stellar customer service.
Is there a solar tax credit in Hawaii?
Yes! In fact, Hawaii has one of the best statewide solar tax credits in the country. The Renewable Energy Technologies Income Tax Credit (RETITC) provides a tax credit to your personal income taxes of up to 35% of the total system cost, up to a maximum of $5,000. Most residents will qualify for nearly the entire $5,000, as the percentage is based on your total before the ITC is applied.
Is solar installation worth it in Hawaii?
For the large majority of Hawaii homeowners, solar panels are an incredible investment and a lucrative one at that. Hawaii has the highest electricity rates in the entire country, averaging around 43.11 cents per kWh, which is nearly triple the national average of 14.92 cents per kilowatt-hour. The massive potential savings of installing solar, plus the fact that Hawaii experiences around 240 sunny days per year — compared to the national average of 205 — makes Hawaii one of the best places in the country to go solar.
Additionally, companies like the Hawaiian Electric Company (HECO) offer net metering, which credits you for any overproduction and helps you eliminate utility bills altogether.
What is the most affordable solar company in Hawaii?
This is a challenging question to answer because there are many factors — other than the installer you choose — that affect your total system price. However, if you’re just going by average all-in costs, then Rising Sun Solar is the most affordable. Keep in mind that Rising Sun is also our pick for the best solar company in Hawaii, which means the value-to-cost ratio is astounding.
How much does solar cost in Hawaii?
The average solar panel system in Hawaii costs around $12,000, which assumes a typical per-watt price of $2.70 and an average system requirement of 6 kW. The $12,000 average is after the 26% federal solar tax credit is applied. If you also consider the state tax credit, you could be looking at upfront costs closer to $7,000.
Is solar energy popular in Hawaii?
Yes, given the high cost of energy and the abundance of sunlight, solar is very popular in Hawaii. The state ranks 16th overall for solar adoption, but the state’s Renewable Portfolio Standard (RPS) set a goal for the whole state to run entirely on renewable energy by 2045, which means the popularity of solar is expected to rise in the coming years.
What are the best solar companies in Honolulu, HI?
Rising Sun Solar, SunPower, and RevoluSun Hawaii are our top three picks for the best solar companies in Hawaii, and all three of these installers service the island of Oahu, where Honolulu is located. As such, we confidently recommend any of these three companies if you’re looking to go solar in Honolulu.
Which solar company in Hawaii has the best reviews?
The overall quality of service within the local solar industry in Hawaii is outstanding, so there are quite a few companies that maintain near 5-star reviews across the board. Rising Sun Solar and RevoluSun are both companies with stellar online reviews and ratings, as well as a track record for outstanding customer service.
