If you’re looking for a great solar provider in Hawaii, you’re not alone. Hawaiians see the most expensive electricity rates in the country, with an average monthly utility bill around $163 (the national average is $117). It’s no surprise that more and more Hawaii homeowners are turning to clean energy solutions to lower their electric bills.

You can search the web for the best solar companies in Hawaii, but few review sites take the time to research what’s most important to locals. Here at EcoWatch, our team of solar industry experts has done in-depth research on factors affecting solar in Hawaii to determine the best solar installers near you.

What Are the Top 5 Solar Companies in Hawaii?

The solar industry is growing in Hawaii. With over 95,000 solar installations, Hawaii now sits as the 16th most popular state for solar — jumping up from the 28th spot in just one year. The table below provides an at-a-glance view of the best solar companies in Hawaii for a quick comparison. 

As you’re looking over our top solar company picks in Hawaii, you might be surprised that some popular solar installers — like Vivint Solar — aren’t included in our reviews. This is an intentional decision made by the EcoWatch team due to issues like lawsuits and reports of poor customer service in Hawaii.

Note: The EcoWatch Ratings you see in the company snapshots at the top of this page reflect our overall assessment of the company, but our rankings reflect the best solar companies in Hawaii, specifically. If you notice that a company lower on our list has a higher EcoWatch Rating, it’s likely because it’s a great company but there are better installers for this specific area.

1. Rising Sun Solar 

Rising Sun Solar is one of Hawaii’s oldest and largest solar companies, serving over 5,000 customers on the Big Island, Kauai, Maui and Oahu since 1986. The locally owned company provides a wide range of solar services, including custom designs, installation and maintenance for solar panels, solar shingles and batteries. It also offers a variety of the top solar brands, including Tesla, LG and SunPower/Maxeon. Plus, all of those products offered by Rising Sun are protected by a 25-year warranty, with its installation labor covered under a five-year warranty.

Aside from having great reviews about customer care, Rising Sun has solar industry affiliations with the Solar Energy Industries Association (SEIA) and is certified with the American Solar Energy Society.

When it comes to payment, Rising Sun offers $0 down solar financing, as well as solar leases and power purchase agreements (PPAs). The most unique thing about Rising Sun is that it offers a price-match guarantee if you get a lower quote from any other Hawaii-based solar company for a similar system.

Pros for Rising Sun Solar

Rising Sun is a solar veteran with industry affiliations and Better Business Bureau (BBB) accreditation to back up its outstanding service. Coupled with the fact it’s a locally owned company, there’s no doubt Rising Sun is one of the best solar companies in Hawaii.

  • More than two decades of experience in the solar industry
  • Affordable solar panel options with price-match guarantee
  • Locally owned with a great reputation for customer service

Cons for Rising Sun Solar

There’s not much we don’t like about Rising Sun, but if we have to pick a con, we’d say it’s that the company’s part and labor warranty only has five years of coverage — the industry standard is 10.

  • Part and labor warranty only 5 years

2. RevoluSun Hawaii

RevoluSun was founded in 2009 in Honolulu and became so successful, the company actually expanded to Massachusetts and Idaho. RevoluSun offers solar panel installations, solar hot water systems and solar energy storage solutions. But aside from solar, it’s also an air conditioning contractor specializing in home energy efficiency and Smart Home product design and installation. In fact, one of its popular products — the SPAN smart panel — allows you to control all of your solar, storage and electric vehicle systems from one smart device.

RevoluSun only carries top-tier solar brands, like SunPower, Tesla Solar and Panasonic. But it still makes residential solar accessible, with multiple financing options (cash, $0 loans, solar leasing) and claims to be Hawaii’s “only local lease provider.” Additionally, RevoluSun has outstanding warranty coverage, including 25-year product and production guarantees and a 20-year roof leak warranty. As a SEIA member and BBB-accredited business, you can trust that RevoluSun is one of the most reputable solar installers in Hawaii.

Pros for RevoluSun

With RevoluSun’s impressive offerings, industry affiliations and above-average warranty, it’s no surprise its team has completed over 8,000 residential and commercial solar projects in Hawaii.

  • Offers some of the best solar technology
  • Variety of financing options, including an in-house solar lease 
  • Above-average warranty coverage, including 25-year product and production and 20-year roof damage.

Cons for RevoluSun

There are very few things to dislike about RevoluSun. Although it carries some of the top solar panel brands, it doesn’t have a wide range of options to choose from. Plus, top-notch solar technology can often be more expensive.

  • Doesn’t have a wide variety of solar panel brands
  • May be more expensive than competitors

3. SunPower by Eco Solar 

SunPower is one of the biggest national solar providers, and its presence was brought to the Hawaiian Islands in 2008 with its partner Eco Solar. Based in Honolulu, SunPower by EcoSolar has a 20-person team of highly skilled solar technicians and has installed more than 1,700 residential and commercial solar energy systems across the Island of Oahu, including in places like Mililani, Pearl City and Waipahu.

Along with solar installations, SunPower by EcoSolar is dedicated to energy efficiency, offering free in-home consultations to define your household’s needs and a review of your personal electricity usage to outline simple energy-saving ideas. If you do decide to choose SunPower by Eco Solar, you’ll get a customized design of your photovoltaic (PV) system.

Because this company is a SunPower company, it only offers solar panels manufactured by SunPower’s system company, Maxeon. And if you’d also like a solar battery, your sole option is the Tesla Powerwall. All products are covered by a 25-year product and production warranty, while Eco Solar’s installation is covered under a five-year workmanship warranty. You can pay for the service with cash or a solar loan, or you can sign a lease or PPA with Eco Solar.

Pros for SunPower by Eco Solar

Being backed by SunPower — one of the leading solar companies in America — is a huge plus for Eco Solar. 

  • Some of the best solar technology in the nation
  • One of the most reputable solar providers in the industry 
  • Dedicated to energy efficiency and savings

Cons for SunPower by Eco Solar

SunPower by Eco Solar is only an option for residents and businesses on the Island of Oahu. Although SunPower has access to the best solar technology, choosing SunPower by Eco Solar means very few brand options and likely higher prices.

  • Only serves Oahu
  • Limited solar brand options
  • More expensive than competitors

4. Malama Solar

The word Mālama means “to take care,” and Malama Solar has earned that name with a stellar reputation for customer care and dedication to taking care of the planet through renewable energy solutions. Malama Solar started as a small, family-owned company in 2017 and quickly became one of the fastest-growing businesses in Hawaii. It’s currently headquartered in Honolulu and serving homeowners on Oahu and the Big Island, but representatives with Malama tell us they’re working on expanding to serve all of the Hawaiian Islands soon.

Malama Solar offers a handful of solar panel brands, including LG, Panasonic and Q Cells. For battery installation, it carries the highly desired Tesla Powerwall. All solar panels are backed by a 25-year warranty, while the battery warranty varies between 10-15 years based on the brand. Malama also offers an above-average 10-year workmanship warranty and a 2-year roof leak warranty should anything be damaged during the solar installation process. Lastly, Malama offers a handful of solar financing options, including low-interest loans and solar leases.

Pros for Malama Solar

Malama Solar is a local, family-owned business that treats its customers like Ohana, while also being backed by industry certifications. With a good variety of solar panel brands and financing options, Malama is helping to make solar more accessible to Hawaiians.

  • Technicians certified by the North American Board of Certified Energy Practitioners (NABCEP)
  • Good variety of solar panel brands
  • Local, family-owned company

Cons for Malama Solar

The biggest con for Malama solar is its lack of experience as a company, as it was only founded in 2017. Right now, Malama is only available for homeowners on Oahu and the Big Island but will expand soon.

  • Founded in 2017, not as experienced as competitors
  • Only serves Oahu and Big Island as of early 2022, but will soon be expanding to other islands
  • Slightly limited service offerings

5. Independent Energy Hawaii

Last but not least on our list of best solar companies in Hawaii is the independently owned Independent Energy Hawaii. Although just founded in 2019, Independent Energy boasts a team of skilled electricians and solar technicians with more than 20 years of industry experience. That expertise is backed by NABCEP certifications and memberships with the SEIA and American Solar Energy Society.

Independent Energy Hawaii performs solar panel installations, removal and cleaning services and offers both solar batteries and residential electric vehicle chargers. If you choose this company, you’ll get solar brands like LG, Pika/Generac, SolarEdge and Tesla to choose from. All solar panels are backed by a 25-year warranty, while other equipment and labor are covered by a 10-year warranty. Independent Energy also offers in-house financing options for its customers.

Pros for Independent Energy Hawaii

Independent Energy Hawaii may be a newer company, but it’s bringing a lot to the table. Its industry affiliations, even at its young age, tell us this company is serious about renewable energy solutions and is looking to make an impact.

  • Industry certification and affiliations, including SEIA and NABCEP
  • Good variety of solar brands
  • In-house financing options

Cons for Independent Energy Hawaii 

Although decorated with solar industry stamps of approval, Independent Energy only has a few years of industry experience under its belt. EcoWatch typically likes to see at least 10 years of business experience so we know the company will last the course.

  • Founded in 2019, not a long proven track record
  • Not many online reviews

EcoWatch Criteria for Selecting the Top Solar Company in Hawaii

The EcoWatch team compiled this list of the top solar contractors in Hawaii based on more than 20 factors. The criteria outlined below are some of the more significant factors that influence our rankings. You can learn more about our process by visiting our methodology page.

Warranty

man making sure solar panels are installed correctly

Solar photovoltaic (PV) systems are expensive, so you want to make sure your solar system is well protected in the event of damage. Solar installers almost always provide some kind of warranty to cover either equipment, labor or both. Here’s a quick explanation of solar warranties and the minimum lengths we look for:

  • Product warranty (also called manufacturer’s warranty): Covers each specific part of the solar panel system in case of defects. Industry standard is 25 years.
  • Workmanship warranty (also called labor warranty): Covers the design, assembly and installation of your system (think roof leaks, faulty wiring, etc.). Industry standard is 10 years, but the best companies offer 25 years.
  • Performance guarantee (also called output guarantee): Ensures your system produces a certain amount of energy over time. Top companies will offer 25-year performance guarantees.

While nearly all solar installers offer warranties, our team tends to favor companies that offer above-average coverage lengths.

Year Founded

While there are some newer companies that made our list of best solar companies in Hawaii, EcoWatch tends to favor solar providers who have a lengthy and proven track record of service. The solar industry is booming in Hawaii, which means there’s a chance that shady, “fly by night” companies will pop up trying to capitalize on the market without having the skills to make it as a business. Remember, your warranty only holds up as long as your solar installer does. So, you want to make sure you’re hiring a reputable solar company with years of industry experience under its belt.

Services Offered

Solar installations work differently depending on the needs of the homeowner. For example, if you live in an area prone to power outages, you may prioritize a solar backup battery. Maybe you prefer a solar roof over the typical solar panels. Or, maybe you drive an electric vehicle and are interested in installing a solar EV charging station. EcoWatch considers the services each solar installer offers and gives higher scores to companies that have more variety.

Brands of Solar Equipment Offered

When installing solar power, you might need (or want) a specific brand of solar technology. EcoWatch takes the variety of brands offered into account when scoring a solar company because we want to highlight companies that have the most to offer our customers. However, we may have picked some companies that only have a few installers because the brands they do carry happen to be the most efficient solar panels or the cheapest solar panels or what have you. Same goes for homeowners who may want a specific product, such as a Tesla Powerwall battery — not all companies sell those.

Industry Affiliations

When solar companies are registered as B Corporations, or if they have connections with industry giants like the Solar Energy Industries Association (SEIA) or the North American Board of Certified Energy Practitioners (NABCEP), that tells us it is serious about making renewable energy more accessible and isn’t just trying to make a profit. Solar installers who have these affiliations score higher with EcoWatch.

Size of Company

While there are solar companies both big and small that can take care of all your solar needs, the size of the company you choose to work with can greatly impact your solar installation experience. Larger solar companies may have better deals than their local competition because they can buy their solar equipment in bulk and often have more resources at hand. However, they tend to lack when it comes to customer care and local knowledge about solar incentives and rebates in Hawaii.

On the other side, a smaller solar company might be more expensive and could take more time to complete the installation process. But local installers are also more likely to deliver top-notch customer care and expedite your connection to the power grid for things like net metering if they have relationships with local utility companies. At EcoWatch, we highlight the best national solar companies and the best local Hawaii companies so you can decide which route is best for you and your home.

Solar Pricing and Financing

EcoWatch values variety in every category, but it might be most important when it comes to solar financing. We know that installing solar isn’t cheap, so we want to highlight companies that are most likely to work with you to make solar the most accessible. As such, companies that offer more means of payment, such as solar loans, tend to score higher in our ratings.
