Services
Mercury Solar is an experienced group of solar experts. We specialize in cost-effective solar designs that provide renewable solar energy to residences and businesses in Honolulu and throughout Oahu and the rest of Hawaii. Our team of solar energy professionals has been working in the local solar industry for nearly 35 years, a fact that sets us apart from the competition as being one of the most well-established Honolulu solar panel companies.
At Mercury Solar, we are not simply a "module monkey" specializing only in the installation of photovoltaic (PV) systems. On the contrary, we can assist you with selecting and installing any one of a wide variety of different types of solar power equipment and we are ready to take immediate action to help you.
Approximately half of the energy used in most buildings in Honolulu and throughout Oahu is consumed in cooling systems. Currently, electricity prices in Hawaii are nearly more than three times higher per kilowatt hour than on the mainland. Your business stands to gain greatly from doing anything to reduce the amount of money spent every month on cooling.
Solar modules, solar cooling and solar water heating are not the only types of alternative energy solutions that we offer to our customers at Mercury Solar. In addition to the installation and maintenance of systems for collecting and harnessing the free and clean power of the sun, we can also assist you with implementing a waste heat recovery unit on your commercial or residential property.
Over the last few years, the solar industry in Hawaii has been encountering more and more roadblocks. From the "red zone" regulations regarding grid penetrations (restricting how many homes in any given area can have PV), to more recent 2-for-1 energy exchange rates for power fed back into the grid, Oahu's residents are finding the process of getting solar increasingly time consuming and tedious.

My husband and I have been making payments for a year on our system that we don't have yet. We can't even get a straight answer about what is taking so long with the permit. My husband called the permit office and they said that it was canceled. He has tried to talk to Scott about it and still no resolution. They keep offering to send money to off set our electric bill, but we had to claim on taxes. We just want our pv system installed.

I have been using Mercury solar for years. They started great, but as of 2021, they are self destructing. They do not return my calls or deal with my warranty problems. They have been overwhelmed, while a few of their employees have quit. I visited their office and it is a disaster area with files and equipment everywhere, almost as if they were about to move, but that's the way it's been for a long time.
I gave these guys a lot of chances, called and emailed dozens of times over a year, waiting for repairs, dealing with problems with my panels and batteries. I have been very patient, but I no

Been working with Mercury Solar since I first installed the solar panels for the water heater 15 years ago. Added photovoltaic and batteries about 5 years ago.Took a while for Scott to get back to me however, we finally got things worked out. I am awaiting replacement batteries as he honored the warranty on the older batteries that were not charging properly. Installing more panels for the AC installation. He is extremely busy and gets back to you when he can. I will post again after the additional panels are installed.

I've tried for well over a month to have them contact me in regards to warranty for my 120V inverter that has been bypassed for over a year. The only status I've received is that they're working with the vendor for a warranty replacement. My 240V inverter is probably being overworked now because I'm woken up in the dark twice in the past week. Have they gone out of business due to the COVID-19 pandemic? I just want a phone call but they don't take the time to do that. Why I keep giving them good reviews I don't know. I won't be doing that much longer that's for sure.

Mercury solar installed a water heater system for one home - no problem.
They also installed a water heater and PV battery system for my primary residence. Very disappointed with the service I have received. Spent more than $50k and still not working right since 12/2014. I would honestly say it worked less than 75% since installation. Called numerous times. Changed out batteries, checked inverters. No calls!!! Fought with the receptionist in the past, telling me other people who paid more is still waiting to get their system fixed. Unreal! I escalated it to the owner and it was fixed. Months

I also give zero stars. They have consistently ignored my property managers' and my phone calls, emails, and messages left at the front desk, to have them conduct repairs that are covered by the warranty (on PV panels they installed).
At one point, the main supervisor Rico said he "cannot afford to do non-income producing work right now." I understand businesses can get weighed down, but they have been dragging their feet on this for a whole year now, and I've heard every excuse in the book.
If you're looking for reliable PV/Solar contractors, I do NOT recommend these guys.

Mercury solar is a great solar company! Their customer service is responsive. Their pricing is extremely competitive and their products are proven to last. After calling other more "well known" companies, I got a quote for a battery back- up system from Mercury. The people were prompt, friendly and the price was literally thousands less than all other competitors. I also have a solar pv system that Mercury installed over 5 years ago that is still going strong! Why go anywhere else when Mercury has the best of all worlds. Were they perfect? No. Of course not. What company is perfect?

We recently had Mercury Solar install nine additional PV panels at our home, in addition to the existing Net Metering system which they installed on our roof several years ago. They got it done in a short period of time before the end of the year, as we required.
We selected Mercury Solar for this installation in large part because of our experience with them. It started over 20 years ago, when they installed our solar water heater system. The excellent service they provided for that system was a major factor in our decision to have them install our initial PV system, as was the knowledge of

We purchased blazing tubes and a hot water tank. The salesman assured us they had cracked the code with permitting, and sure enough the company had the tubes installed within 3-4 weeks. But almost a year later we STILL don't have the new hot water tank installed that we PAID FOR almost A YEAR AGO. Every time we call we get one excuse after the other. My opinion is with all the solar options on the island, this one shouldn't be your first choice.

After the technician Adam left the company, it appears the company can no longer provide post sale service. I purchased a lot of solar panels from this company, however, after few months, I noticed my electricity bill went extremely high. My guts tell me something must have gone wrong with those solar panels. I called since last September and so far no one came. They don't even bother to just check. The scheduler Winnie kept telling me there is no one available. This is unbelievable! Once panels are sold, no service anymore even they said at least one year warranty for repair but I guess

I have used Mercury Solar at different homes over the past twenty years. I have been happy with pricing and installations.
More important to me than the actual installations is the after sales service. Whenever I have had any issues, they have promptly addressed my concerns.
I would recommend them for hot water solar panels and photo voltaic panels. I was able to take advantage of both the federal and state tax credits. You should check if you can with your tax accountant as it plays an important part in the decision.
Any installation on a roof has impact on your roof, so make sure you are

My experience with Mercury Solar was not as pleasant as advertised. The salesman was clearly good at his job; they oversold a product with average quality and below average customer service.
Their financing offers are misleading and complex. The state and federal tax credits they claimed would make this installation affordable never materialized. Thus, I was stuck with a bill nearly twice as expensive as originally quoted.
I was promised installation of my backup battery system in January of 2017. It is now June, and I have yet to see any batteries or even have my panels wired into the grid

We first were introduced to Mercury Solar in 2010 through friends for installation of solar PV panels. Because of finances, at that time we chose to install only 20 Panels instead of a recommended 41. The paperwork process by Mike, the sales person representing Mercury Solar was very efficient. The process of getting the HECO permit done at that time was a little more arduous but we got the whole thing set up for Net metering by early 2011. Since then, we have been pretty impressed by the near perfect assessment of cost savings on our electrical bill. Now in 2016, after a lot of thoughts, we have

When solar was first starting to pop up everywhere, we couldn't it afford it because most companies wanted payment up front.
But Mercury Solarvmade it very easy for us to afford PV system. Boy was it worth it.
The company had great reviews and is one of the leaders in solar installation in Hawaii.
Fast, efficient, trouble free installation. Helpful, knowledgeable.
I highly recommend Mercury Solar if your looking for a company to install a system on your home.

We used Mercury Solar to install PV panels and it was NOT a good experience.
The first red flag was when they showed up to install the panels and the guy installing them was on the phone with his boss telling him how to put the panels in! After the panels were installed the roof started to leak where they had drilled holes in the roof. We complained about it, but they insisted that this was not due to them, when clearly the hole in the roof was due to the panels. This finally was resolved.
The panels appeared to not be working well and there was not much energy created. We called them
