Wow! So pleased with my solar installation. There are lots of companies that sling panels on your roof and, boom, you have solar. Harmon was amazing to work with from start to finish. Here is why: They were informative through the whole process. Their installers were super professional. They were safe, courteous, communicative, and just plain nice. Their work is top notch. I've seen lots of panels with Co duit running all over the place. Harmon makes it look like mtly panels are the only thing on the roof. Every connection was installed in the attic so it looks much cleaner. Value. I've gotten got great results from my panels and the price I paid was more than fair. Service. They have been responsive to all my needs, even months AFTER I paid them and they were done. Couldn't be happier. read more

Spoke with Dennis Alessandro, he gave an astronomically high bid, which is completely unethically priced for a job. 60k for 15 kw system with 2 batteries is abhorrent. I hope people search him and don't get taken advantage of. When I respectfully discussed this with him he became nasty, condescending, and disrespectful, saying he had been doing this 16 years etc. Buyer beware!!!! read more

I really wanted to like this company, but my solar installation has been an absolute nightmare. My panels were installed almost 4 months ago and still haven't been turned on. In the meantime, my power has been shut off twice for over 3 hours while crews worked--yet the project is still incomplete. Communication has been almost nonexistent. My project manager will reply if I email her directly, but otherwise I receive no proactive updates about progress or next steps. When the field crews finish for the day, they just leave without saying a word. I've been left with panels unscrewed, wide open, and conduit scattered around my yard. Most recently, the electrical crew assured me everything would be finished and turned on--but once again, it wasn't, and no explanation was provided. This has been one of the most frustrating customer experiences I've ever had. I went into this wanting to recommend them to coworkers with new builds, but now I'm warning people to stay away. read more

Absolutely amazing. So very thankful. Wonderful customer service and care. I would recommend

Harmon solar is a predatory solar contracting company that hires out electrical engineering to others who are (more) experienced. They poach contracts and designs from their competitors. They design with crappy gear to max their profits - value engineering is not part of their scope. I'll just say they are better at looting than they are producing quality PV systems. It is not necessary to step over others to get ahead, but they seem to excel at that. read more

It's my buddies house. They have taken a 15 day job and turned it into six months why? Because they don't listen to the customers. They think they know what they're doing. They don't know nothing you'd be better off from what it sounds like hiring three monkeys to do it. At this point, I told my buddy you should probably see an attorney cause it looks like where this is where it's gonna go because you're just getting the runaround up 10 holes in the roof they don't want to repair's the way it should be . Act like it's customers fault it still don't wanna listen when the customer has a background and construction. I'll be honest with you my buddy 15 years ago would've gone through this place like a bull in the China shop. but we've now come to a point in our lives where we're a little older, a little equalizer and having enough brains to know the difference between right and wrong. They know they're wrong. Wanna admit to their mistakes won't repair the roof correctly that yet still put you off day in and day out not a company I would recommend put in my mailbox. That's the truth. read more

So all you can comment on is the timeline and a very generic statement that you design each setup differently? What about putting panels on the north side, is that ok? What about quoting me a system with 100% offset? Is that ok too? Again you don't care about your customers or their concerns and your employee (Dennis) is rude to Harmon customers. That's ok too? read more

We had a few surprises during set up, one was failed roof inspection, added $13,000.00 to bill. Shingle order was short, had to wait 2 days for that. A few other small items with roof finishing that were quickly fixed, overall, a very good job, system is up and working great, very clean install, great sales and project manager who had to work around bad weather!! read more

See all

Harmon Solar came through for us when our solar panel installers refused to fix a problem we were having. Harmon Solar was professional, prompt, and affordable. Thank you Harmon Solar. I highly recommend this company. read more

Although they told me, it would be a few months I waited maybe a month or two longer than expected, but they did pay my electricity bill for the inconvenience. Other than that I haven't really had any complaints. The equipment works great. I had one solar panel that was not producing and they were able to fix it online right away And get it back up and running. I've had the system since 2018 and after Covid hit I started getting small bills here and there so I called them and they upgraded me three more panels since 2018 I've gotten very small bills from APS like maybe 10 or $20 here and there But then after the upgrade I've been getting checks from APS for overage charges in 2022 I received a check for $360 and 2023 although it was a hot year I still received a check for $165. Overall I'm really happy with Harmon Solar. I did pay my system off after a year of having it, so that helps. I feel like their prices are very reasonable and their customer service. Pretty great. read more

Still trying to figure out how paying $400/mo to Harmon offsets the $98 solar credit from APS.

Buyer beware. They tell you only a portion of what is needed or will happen and by the time you find out it is too late.

Extremely knowledgeable about the solar system and inverters. Very professional and took the time to explain the difference in inverters before being selected as our vendor and after installation on how to monitor the system. The electrician was very particular about cleaning up and patching the holes to make it look as if it was always there. Highly recommend!!!! read more

I never said your panels caused my roof damage. $2000 savings compared to an extra $10000 more that I have to pay due to your greed is not generous. You said yourself as long as the roof is strong enough to cover the warranty for 5 years. Your roof inspector knew the approx age but it's whatever. You guys won't admit. I went with your company because I had great reviews on you from actual customers. Privately owned, great team, best deals, integrity, turns out your just the same typical sales people that would say anything to make a sale read more

Very pleased with Harmon Elec/Solar. Customer Serv. in my honest opinion is top notch. Jessica was amazing! Technical component very good. Initially, there was a minor glitch in the system which , no fault of the installer but a product defect on inverter. Harmon immediately responded and got the system on tract . Enjoying the savings on utility bills which would have been sky high if we stayed same with just APS. A wise decision to go solar and most importantly went with a reputable company like Harmon They were highly recommended. Thank you! read more

Everyone at Harmon, from sales to our Project Manager to the installation crew have been professional, accessible and genuinely nice to talk to. They have instilled confidence that all of the details were being kept track of every step of the way. Even the permitting applications (APS and City of Phx) were taken care of, then communicated to us upon their acceptance. If you are considering Solar for your home, you owe it to yourself to talk to the good people at Harmon Solar. read more

Yet another desperate company that refuses to respect peoples property and those of us who take the time to post "NO SOLICITATION" & "NO TRESPASSING" signs. No I did not do business with this company because they they insist on breaking the law tells me enough to stay away from Harmon. They put a flyer on my property that is clearly stated both no soliciting and no trespassing. I am sure they will come back with some lame excuse like "sorry we hired a marketing company" which I don't care. If that is the fact I don't care because you are responsible for the company you pay to market your advertising and there behavior with your flyers. Only companies I see do this are nothing but desperate and I wouldn't trust a company like this to watch my grass grow let alone do expensive work like solar installation. read more

Zero starts wasn't an option... We hired Harmon solar to design and install solar panels on our house, in Gilbert AZ. The total cost of everything totalled over $30,000. The experience with Harmon was rough from the very beginning, we could not get them to show up when they said they were going to show up, or they would show up, and get halfway through something and have to leave, leaving the project incomplete. The first major blunder was then they installed a behemoth of a solar inverter right on the front corner of my house, sticking our like a sore thumb. It looked absolutely atrocious. I called to complain to have them move it, and they said 'you approved this in the design'. After arguing back and forth they did end up agreeing to move it. This process took approximately 6 weeks from the first complain to when they finally showed up the first time to move the inverter. When I spoke to the installers the day they were to work on it, they said they themselves would have complained about it to.. Makes me wonder why no one thought to bring this up before installing it. Anyway, they came out to move the inverter, cut all of my solar wiring, only to find out that whoops, they cant continue. So, this left us without solar for nearly 3 weeks because that is how long it took for them to come back out to move the inverter the second time. They then left before SRP came out to reinstall the meter, they literally just disappeared and never told me anything. The solar still didnt work and I had to wait several more days for SRP to come back out and reinstall the meter. Now, fast forward ~6 months now that we've been using the solar, we've noticed little to zero savings coming from this $30,000 disaster. Come to find out, they had moved us to a plan that didnt make sense for our panel layout, and the panel layout doesnt make sense for the SRP solar plans, because my solar basically stops working before 2pm every day, coincidentally that is when peak times with SRP begin, thus making the solar literally pointless. I have a 3000 sq ft house and still pay over $400 a month in (for July 2020, used approximately 3000kwh). They also did not install a Load/Demand manager system on my house, which after talking to MANY other users of solar, and other companies as well, everyone has said it is ridiculous that this was not included in the crazy price we paid for these panels. Harmon refuses to return my emails or my calls, the project manager has been rude from day one, very nonchalant about everything. I recently tried calling to get back in touch with management and has been forwarded to voicemail each time. This is the worst financial decision I have every made in my life. read more

Harmon installed a solar system on my property. I have been very pleased with it so far. The installation went pretty smoothly Whenever I had questions or concerns someone from Harmon responded quickly. The physical installation was trouble free. Harmon kept the worksite meat and tidy at all times. Overall, I was pleased with the installation and have been happy with the system so far. I recommend Harmon with no reservations. read more

This was an important decision. I did my research, compared companies, compared their service, their panels, their reviews, their long term stability. I guess I need to start with the fact that I am an Elon Musk fan boy, but didn't go with his company. He wouldn't mind, I'm sure of it. I had spreadsheets, literature, and a makeshift algorithm for reviewing all of the data. It came down to two things: price per KWH and panel quality. The price per KWH was a tie with another company I checked out, and less than the third. However, the panels Harmon was going to put on my roof were a higher quality, more efficient panel which meant the system could generate more power than both of the others using the same number of panels. I liked that. Plus, the panels are made in the USA and by Sun Power, a large and reputable manufacturer. After a couple of months of this, I went with Harmon. When I was talking with them, they assured me that they go through all of the necessary processes with the town, the HOA, and everyone else. They did not lie. They made sure they got all of the necessary permits, inspections, and HOA approval. My HOA was slow to get back to them, but their followup was second to none. The installation went off without a hitch. Their installers were professional and courteous and did an amazing job. The system has to be hooked into your wifi so it can be monitored remotely. They brought the wire into my house near where my router was set up. A few months later, I switched cable providers and moved the router. They came back in, installed a device that send wifi through my power outlets, and moved their hardware... at no charge to me. I like these guys. I still get an email every now and then from the sales guy who got me set up. The system has been running for almost a year now, and I saved $600 on my energy bill this year. That is 30% over last year. I couldn't be happier. One cautionary tale with the solar lease that does not reflect AT ALL on Harmon, it is possible with any company you choose. When someone buys your house, they have to assume the lease. They also need to qualify as if it were a loan, because, basically, it is. Be aware that a sale of your house might fall through because the buyer is unable to qualify for the solar lease. However, it is so inexpensive that if a buyer can't qualify, they are more than likely not going to make it to closing at the cost of your house. This happened to us a couple of months ago. In the end, this is the best purchase for my house I could have made. Everyone should have solar panels in this state. I whole heartedly recommend Harmon Solar read more

They left a lug loose and burnt up one of the disconnect switches.. Also, re-labeled my panel breakers wrong

This company is reliable. I recommend them for any solar issue even if they didn't install the system.

I recently went under contract to purchase a home which featured a solar system. This was my first exposure to solar, so based on a positive reputation I hired Harmon Solar to inspect the solar equipment prior to close. The technician was thorough and after inspecting he took time to explain to me everything I should know about the system. As a result I feel much more educated about solar and would certainly go back to Harmon if I ever have a future solar need. read more

What a disaster Harmon solar is........ Our esteemed sales representative made a $ 5,000.00 mistake and then wouldn't fix it. The first rep we had: 1) has a hearing problem. Can't keep appointments, DOESN'T LISTEN......... made several mistakes. I called the "Boss" who promised me the next salesman would help us..... all he did was discover the first guys' mistake......... sort of kills any credibility, don't you think? read more

NRG Solar put in my work order ticket. I am always worried when a contractor comes to do work that I am not paying for (ie: work under warranty), because there's no sales opportunity in it for them. However, the gentleman who came from Harmon was very courteous, helpful, and informative. He made the modifications needed after an electrical surge caused by a lightening strike shorted my telemetry system for my solar. He was so helpful and polite, what a breath of fresh air. I would absolutely recommend Harmon Solar's technicians, and I hope NRG uses them again if I require warranty work. read more

Overall my experience with Harmon Solar was... okay. I signed up with Harmon because they seemed to have a really good understanding of solar technology, government regulations, the solar market as a whole and came in at a really good price compared to competitors! All pluses! Ben was a really good sales associate and knew his stuff. There were some hiccups along the way but when they took action to get something done, they were usually fast at finishing the job. One of the problems was how much effort I had to put in to keep the process moving on my solar installation! For the first half of the project, there were times it felt like if I didn't call to follow-up, my project would stay stuck in limbo. However, the most frustrating part of the process was the payment. Harmon Solar was using Sunrun panels but there was such poor communication between the two companies it was a task figuring out who and how to pay for the panels which only slowed down the process more! In spite of all this, one reason I still call the experience "okay" is because of the project manager who took over my case half way through and was so helpful! Jessica was very responsive and consistently explained at what stage the project was and gave me updates on what was going on (even when it wasn't a status update Harmon Solar was proud of!) She was transparent and empathetic when there were delays or miscommunications from Harmon and was very personable. If she wasn't the project manager on this job, I might have called it quits and fought with Harmon to refund my down payment. She helped me see it through which salvaged some of the experience for me. Thanks Jessica! read more

I had my solar put in last September. We ran into a rather large problem that I won't get into, but my project manager held in there with me and we got it all resolved. I was impressed. They could have just ignored me and not helped out with the problem, but they didn't. I would highly recommend Harmon as an honest and ethical company. read more

We have contracted for roof top solar twice. Harmon Solar performed both of our installations. In our case we used Sunpower Solar products. Research indicated that they are the best product available for a number of reasons. I was formerly self employed as a general contractor. I also spent twenty years in the wireless telecommunications field building and integrating complex wireless networks. As such I have a lifetime of experience dealing with contractors and sub-contractors. In my experience Harmon Solar has been an excellent company to work with. Our installation wasn't without minor issues. The reason we chose Harmon is because of the strength, experience and integrity of the owners. I need to know that the company working on my property has the skill to perform the work and will stand behind their work during and after the installation. I'm more than satisfied with Harmon Solar and would recommend them to friends and neighbors without exception. read more

JUST IGNORED. Went through their sales pitch, inspection, cutting holes in two places in my ceilings, patching ceiling holes, changing my APS plan from a savings plan to a regular plan---and months later, no installation, no calls, only several ENORMOUS BILLS from APS, Thought I was kissing hugh electric bills goodby...not with Harmon. Received the largest fall electric bills ever! So much for following their instructions to drop my savings plan. Called, asked what happened to my installation. After employee looked around on her computer, she apologized and promised someone would call me shortly with an update on my installation. No call. Called back the next day, couldn't reach the person handling my account. Well, it was 10 to noon, guess she sneaked out early for lunch. Avoid these folks. read more

Harmon was a great company to work with. Explained the benefits of solar well and helped us throughout the installation to get setup right with our electrical provider. I highly recommend this company to help you decide if solar is right for you. read more

We contacted Harmon solar and they came out and gave us multiple quotes with different configurations for our needs. They provided great customer service and personally addressed any issues we had immediately. The best part about Harmon solar is they don't increase your rates every year like the other companies do. I would highly recommend them to anyone looking to save money. read more

Going solar is complicated. After meeting with several solar providers, I realized I needed to do my own research...so I did! I then met with several more solar providers now knowing what to look out for and what questions to ask. Harmon Electric was the only one I felt wasn't trying to sell me "a great deal only they can offer, and only if I sign on the dotted line soon". Harmon explained ALL my options and then showed me the design that would best suit my needs. I then researched every component included in their proposal. Their straightforward and honest answers to my follow-up questions, sold me on their integrity. I signed the contract, and everything went exactly as they promised. Sadly, the most time-consuming part of going solar is the state and power provider permitting and inspections. The actual install only took two days, commissioning to turn on the system took many weeks. Harmons project manager and installers were all a pleasure to work with. Harmon staff kept me informed on our progress every step of the way...never left me wondering...what's next, and when will this happen? Communication was KEY. My system has been operating flawlessly since the day it was commissioned. I couldn't be happier with having gone with Harmon, and even happier with my very low (and even credits on my) APS bill. Bottom line...go with a company you can trust and feel comfortable doing business with! For me, it's hands down...Harmon Electric! read more

We have solar installed by Harmon Solar in 2011 and we LOVE it! They did a great job and it's working like a charm 9 yrs later! Haven't even had to wash off the panels. read more

My first thoughts were, do I really want to write this review? Then I thought about it. Of course I don't but I really need too. I see perfect reviews only. Nobody is perfect. With that said let me tell you why my situation is far from perfect. It began on Wednesday when I was told about this company that advertises on KTAR. The person could not remember the name of the company, only that the voice sounded convincing and professional. So I emailed KTAR and I asked about it. I was given a huge recommendation by KTAR. Next, I looked at the yelp reviews and was thrilled. So I went to Harmon's website and entered info including my address and received two phone calls. One from Chad and another from Ben. I will have you know my internet assessment gave me a sun score of 79. That is good, I was later told. I decided to call Ben back. I was given a wealth of information more specifically why Harmon was better than Vivint or Solar City whom I had been conversing with. I explained why I did not choose either of these companies and what I had anticipated my solar needs to be. I was told we have 15 kinds of panels and multiple plans and how they would devise a plan to suit my expectations. Sounds great right? I scheduled an appointment for today, Monday (my day off) at 10:00 am. I was so excited by the possibilities, maybe I could even own my panels verse lease them. Not 5 mins later Ben called me back and said Dennis is the best and I want you to have Dennis but he cannot make it to your house until about 1:00. Would that be ok? Hesitant about wasting my whole day off, but still excited about the solar energy opportunity, I agreed. So now 5 days later I am home, its 1:00 and I am waiting for Dennis. Low and behold my phone rings and you guessed it, it is Dennis. He goes on to tell me he left me a voicemail either Wednesday or Thursday saying we were not a fit. Really I said because I have no voicemail messages. And let me remind you that I only scheduled the appointment on Wednesday night at around 6. So I said oh either Wednesday or Thursday? So you don't know exactly when. Ok continue, he says we can only fit 10 panels on your house and it would cost more in the long run than APS. So I said you are suppose to be giving me multiple options and your not giving me any. So this is where I am confused, I have a 2700 square foot house, in AZ. A sun score of 79. Again I live in AZ with approximately 300 days of sun, yet I am not a good fit for solar. So Dennis doesn't want to waste my time, although I think it was more about wasting his time. I call Ben back and he says he doesn't know anything about it. But says I am a man of my word, I will find out more info and call you back. Ben called me back to basically tell me the same thing that Dennis stated. Robot style to my liking anyways. Tells me Dennis left a message, I said ok, lets pretend he left a message. My question is then: Why call me at the appointment time if you felt that your voicemail was good enough to begin with? Hmm, my thoughts and thus my review is because there was no message. Update 10/1/2015 just signed with Sunrun! Guaranteed me 22,000 kilowatts a year. Guess you were wrong. read more

Just like the other reviews bad customer service. Phone Tag is an understatement not only can you never get a hold of anyone but the Quote sent was wrong and did not address the items and size of solar I wanted. After repeated calls and a few emails I am done trying to work with this company. If someone is going to spend 20K plus you should have great customer service. (look at car salesman even though we all hate them for 20k you are never ignored.) read more

Harmon Solar performed an excellent installation at our residence. I highly recommend their services.

Excellent company. All work was done on time, as promised. Personnel were friendly and knowledgeble. High quality workmanship from start to finish. read more

Whoohoo! Harmon and people at this company are as good as it gets. Because of unforeseen circumstances, we were not able to complete the project and had to cancel. They were super at understanding and when we do get solar, we'll go straight to them. Tom Kopp was a pleasure to work with as were Daulton and December. Very responsive. Very professional. read more

I had a terrible experience with Harmon Electric and their "door to door" solar salesmen. Brett was the salesman. He was very unprofessional and was not honest about the costs. I asked him to email me an official quote so I could compare it to the other quotes I received and he would not do it, he told me his boss wouldn't let him. He tried to play way too many games and I went with another solar companies and I'm glad I did read more
