What our happy Customers have to say

First and foremost, they are THE BEST! I have a large home (over 8,000 square feet). Their pricing and their professionalism are far better than the competition. The system installation has completely met my expectations and exceeded. Everything went thoroughly smoothly, without a hitch. There have been absolutely NO maintenance issues since installation.

Honestly, I wouldn't waste my time with any other company.

Cheers and Blessings, Trish ~

Ipsun does try to make their customers happy. I am waiting for a solution to a problem with my panels but am anticipating a good response.

Ipsun Power has been a great company to work with. They answered all of my questions regarding purchasing a solar system, guiding me through the whole process. The install crew that came to my house was very professional, courteous, and definitely knew what they were doing. Even after the project was complete, they submitted all the paperwork needed for me to receive the Fairfax County tax exemption!

Also, Ipsun has a great website where all of my documents, pictures, project schedule, receipts, etc are all in one place, which is a great resource. Plus you get access to a phone app where you can monitor your solar panel performance in real time and trend it over the long term.

Overall, I have no regrets with choosing Ipsun Power!

So very happy with the work! 

Thanks Ipsun Solar team!  The crew that came today was really great.  Dave did a great job of leading all the work.  I'm very happy with the way the panels look, was glad to see the specs/reviews on the JuiceBox and Dave was able to install that inside the garage while drilling a whole for the charger cable access to the driveway.  So very happy with the work!

We unreservedly recommend Ipsun to anyone

It was an absolute pleasure to work with Ipsun Power! Everyone we worked with was thoroughly professional. They did a great job of explaining each step in the process, from the initial evaluation and proposal, through the installation, all the way to flipping the switch. The actual installation was smooth and speedy, and the installers cleaned up after themselves so well that you couldn’t even tell they had been there. They sent us copies of all forms we would need to apply for the solar tax credit. The panels are working beautifully and already earning their keep! We may be a little obsessive about checking the website every day to see how much power the panels have generated! We would definitely use them again and would unreservedly recommend them to anyone.

Solar panels system review from Arlington VA

My solar panels system in Arlington, VA was just turned on. I’m really happy with the experience I had working with Ipsun Solar. I now have 26 panels on the side of the home and 15 on the back and it will be making a major impact on my Dominion bills. By financing the solar project, I get affordable monthly payments that are really easy to handle - Patrick explained exactly how that would work so it’s been a very clear process. The day the solar installers came went really well coordinating with their team was easy. Thanks Ipsun Solar for a great solar project.

Ipsun kept us well informed

We had a great experience with Ipsun Solar and highly recommend them. Ipsun put 11 panels on our roof. We didn’t know much about the details of solar technology and Ipsun patiently answered every question we had. Once we signed they efficiently took care of permitting and HOA approvals. One of our favorite parts was how well they kept us informed. We received an email update every Tuesday, so we knew how things were moving along. Installation day was wonderful. They showed up when they said they would, were respectful, were very kind and patient with a curious toddler, and cleaned up when they were done. We appreciated that all of the folks who were up on the roof wore safety harnesses. Something that impressed me was how prepared Ipsun was for the inspection process. The process to get the system turned on was also efficient. There is an app that we they give you that allows you to track your production. Ipsun Solar was great to work with.

100% professional exactly how business should be done

Ipsun Solar is a fantastic company to do business with! I could not be happier, from the initial meeting with Patrick, to the survey meeting with Humza and finally today's installation. Everyone was 100% professional, extremely cooperative and communicative! This is exactly how business should be done. The entire process took three months from the initial meeting until installation. The CEO even got involved to help move the permitting process along! The crew arrived this morning at the crack of dawn and completed the installation in a little over eight hours.
Ipsun was even able to assist with very low cost financing which put us on the path to energy independence much quicker and cheaper than I ever anticipated. You can feel good about helping the planet and putting money back in your pocket. Most people think an install like this is too expensive. That couldn't be further from the truth. We are purchasing the system over time, making payments which are slightly less than our energy bill (not factoring in the inevitable increase in the cost of electricity). Thank you Ipsun Solar!!

Like a well oiled machine

Our experience with Ipsun was awesome!  From beginning to end the process flowed like a well oiled machine.  We found all levels of staff from sales, technical, installers and office to be totally client centered, helpful and professional.
We originally expected an installation time of two to three months.  Instead we were surprised that our system was installed, all permits and inspection completed, meter placed by Dominion and producing solar power in less than six weeks!
We are very pleased with the installation and our relationship to Ipsun.  They have been helpful with any followup questions as we go along.
We are  happy to recommend Ipsun to anyone considering a solar installation.

Lots of clean energy at a good rate

My solar project was completed last October and has been running smoothly, providing lots of clean energy! Working with Ipsun was very easy, they handled all the permitting, HOA applications, and of course every aspect of design and installation. They have always been responsive to my questions, before and after job complete. I highly recommend this company, in addition to great service, they had the best rates I could find as well.

Sean D.

Superb partnership and explained everything

Ipsun has done fantastic work for me. Even if I am not a technical expert in solar energy, they took their time to explain everything clearly, answer all my questions, and it felt great to have such support before taking those big decisions. From start to end, superb partnership! I highly recommend them.

Nicholas K

Very helpful energy reporting client review

They explained to me in detail how solar works, even via integrative app function. I was able to see in real time how much energy that each household appliance consumes. Very helpful indeed! Thanks, Ipsun Power!

You won’t be disappointed client review

Excellent. Give these guys a go and you won't be disappointed. They designed and installed my residential solar system in DC. Dealt with permitting and inspections. Customer service above and beyond.

They make the whole solar process easy

The crew at Ipsun Power were great to work with, making the whole process easy. It started when they came out to the house to discuss the project. They started work on a proposal, and came out again to photograph the roof and finalize the design. Gave me a number of options for size and financing, handled all the permits and paperwork, and walked me through the whole procedure. Installation was quick and professional, took about a day and a half. Everyone on their team was friendly and professional. I would recommend them to anyone in the DMV area!

Solar project proceeded as expected

I am pleased to be able to recommend Herve Billiet and Ipsun Power as our solar company! From start to finish, Ipsun kept us informed about the progress of our project. I felt comfortable knowing that our system was being designed to fit our needs and budget. Everything proceeded as expected. The installation crew was prompt, courteous, professional, and cleaned up after themselves. We were able to consult with the company after the system was up and running to be sure our electric bills matched expectations and have access to monitoring data. I was pleasantly surprised to find that Ipsun even files the property tax exemption paperwork as well as providing paperwork for income tax credits. I would not hesitate to recommend Ipsun Power if you are interested in making a difference with solar power!

Kim Young

Very competitive price and great communication

Herve of Ipsun Power is a great communicator, who took the time to answer the many questions I had about going solar. He and his colleague conducted a thorough analysis of my property, and quoted a very competitive price. I would definitely recommend Ipsun Power based on their responsiveness, customer service, and attention to detail.

Stephen F.

Positive customer service experience

The most important thing to me about a business is customer service. I have all positive things to say about the customer support I received from Ipsun Power. The team was responsive, receptive to all my questions, and explained everything to me - I didn't feel alone throughout the entire process. Even after installation, they reached out to me to ensure everything was okay. They went above and beyond. Excellent service!

Marcy L.

Electric car charger installed review

Ipsun Power installed a car charger at my house. They did an excellent job, handling the circuit breaker, permits, and connection to the Siemens charger. If I go solar, will definitely go with them in the future!

Chris Pilger

Get the benefits of solar while you can

From beginning to end, Ipsun Power completed their job effectively and professionally. Herve was personally very responsive and helped answer questions. I received a proposal that presented an option to own the solar system or to have a no up-front cost installation. The benefits of each were clearly laid out. Once a decision was made to install a system, all the details were handled by Ipsun Power. Installation was completed in one day. Ipsun Power handled all the paperwork and coordinated the process with PEPCO. Overall, I’m very satisfied with the work and would recommend the benefits of solar while you can get them!


Quick responses with no fuss solar service

Amazing service. I had ordered the monitoring device that needed upgrading. Herve was quick to respond and accommodate what it was that I needed. Sent it out with no fuss. It was a pleasure to see responsiveness and good communication in a company as so many lack this skill.

Ipsun to the rescue solar repairs and expansion

I first became aware of Ipsun when my Enphase Envoy suddenly quit on me and they happened to be the closest Enphase provider in my area (Washington DC Metro). They responded with lightening speed to send me a replacement and followed up to be sure I was able to install it with no problems. At the end of December we had part of our roof torn off in a wind storm and had to have it quickly replaced. Ipsun to the rescue to have our existing system moved off the roof so that repairs could be done. So impressed with their work and feeling like a VIP client, I looked to them to expand on my system. They innovated a solar awning to allowed for an additional 5 panels that beautifully integrated into our system. Not only did it add to our power production, it also works having a passive effect! I highly recommend Ipsun and if I had more room would absolutely have them expand even more on my system.

For everyone thinking about solar

They upgraded my solar panels to LG 360 watt panels for higher performance and efficiency. Professional, responsive, helpful, and knowledgeable staff. I recommend them to everyone thinking about going solar.

Straight shooters: delivered as promised on time

Straight shooters. My situation was unusual in that I wanted to replace an existing system while using components. And then when the utility capped the size of my proposed system, I fought back by filing a complaint. This added more than a half a year to the project, but Ipsun stuck with me. I researched my situation enough that at times I had something to teach Ipsun. But they always listened, never talking down to me. And when it came time to install they delivered as promised, on time.

David Roodman

It’s how you deal with unexpected issues client review

Just got approval for our 9.6kW system installed by Ipsun. They were great to work with all along the way. I believe you can really measure a company you're working with by how they deal with the unexpected issues. We encountered one, not caused by Ipsun, and they worked with us to solve the problem and get us exactly what we wanted. I definitely recommend contacting them if you're interested in going solar.

Tom Ries

Above and beyond: quick and masterful solar process

Above and beyond: this phrase could have been created with Ipsun in mind. Working through my solar installation felt as though a dear friend (or a bunch of them!) took me by the hand and led me gently through it. Each aspect was thoroughly described and explained. I felt confident making decisions with the depth of knowledge provided - never with the hint of superiority or exasperation that is so common. Everyone at Ipsun seems to be downright excited to teach the entire solar process. The speedy replies to emails were breathtaking. Every question I had along the way was patiently answered. When the power company balked at the number of panels to be installed, they quickly handled it, explaining the necessity for it (relatives moving in). They even started to help me find financing as part of their services (though I took care of it). Installation was quick (~2 days) and masterful. AND for the first time ever, I did not have to clean up after workers! I am so proud to have a spectacular solar array providing my power. I count myself lucky to have had this experience with Ipsun Solar.

Phyllis Van Houten

They were communicative the entire time

These guys are amazing. They found a way to maximize the number of panels on my roof allowing us to save. They were communicative the entire time.

In business for the right reasons

Ipsun was great with me. They helped me get the right product for my house in the right time at a reasonable rate. These guys set themselves apart by being ready to go the extra mile for their customers. You can also tell that Ipsun is in the business for the right reasons - to help customers unlock the potential to make money from clean energy rather than paying for old dirty energy. Highly recommend considering them for whatever project you've got.

Matthew Bearzotti

Very professional, courteous, and know what they’re doing

Ipsun Power has been a great company to work with. They answered all of my questions regarding purchasing a solar system, guiding me through the whole process. The install crew that came to my house was very professional, courteous, and definitely knew what they were doing. Even after the project was complete, they submitted all the paperwork needed for me to receive the Fairfax County tax exemption!

Would definitely work with Ipsun again

I had a good experience working with Ipsun. They seemed to me very knowledgeable and professional in their field. Would definitely work with them on another project.

Excellent company

From the start Ipsun Power was great to work with. They did a survey of our property and made suggestions, each suggestion was backed with metrics to help us understand the impact of the system size that we were considering. They were VERY responsive in answering any questions that we had and when we needed time to think, they backed off and didn't pressure us. The workers were very professional, clean and quick. My dog Peanut absolutely loved them which was actually cute as they would pet her over the gate each time they passed. Everything about the experience was top notch and I would highly recommend them if you're considering solar.

Successful Solar Installation attached to 2 Tesla PowerWalls batteries

We have been very happy with our whole experience with Ipsun Power.  Ipsun installed 18 solar panels on our home's newly replaced roof in the Tysons Corner area.  Their pricing was almost identical to the other company we looked at (Tesla), i.e., about $1,000 per panel installed (or ~$700 after the 30% tax credit).  So we decided between them on the basis of service.  At that point, Tesla had not yet absorbed SolarCity but was selling SolarCity panels and installation.  SolarCity had a lot of bad reviews online for workmanship and customer service.  Ipsun had great reviews, but very few of them, which was a different concern for us.  In the end, Ipsun's founder, Herve Billiet, won us over with his honest, detail-oriented responses to our questions; he is an engineer by training, not a salesman.  At Tesla we had been working with a salesman who was very responsive and thoughtful but had no on-the-ground experience with solar panels. As an example of what I mean:  Tesla's salesperson drafted our project plan by using a Google satellite image of our home's roof, and filling the roof area with little PhotoShop images of solar panels at the correct scale, as many of them as he could fit, to make the job size as big as possible.  By doing it this way, his "plan" accidentally covered one of our two chimneys with solar panels.  (He also put panels all over the north side of our roof, which gets much less light.)  Obviously Tesla would've fine-tuned the project plan after doing a site visit, but we felt nervous about whether the salesman and the site team would interface well, and whether we were being asked to agree to a project before the details were clear.  We also felt a pressure at Tesla to max out the project size. On the other hand, Ipsun's owner, Herve Billiet, initially gave us the same type of Google satellite-image pre-estimate, but he insisted on a site visit before going any further, and he did the site visit himself. He ended up coming back multiple times, and answered a dozen detailed emails, before we would commit.  He used a tool that digitally modeled the height of our surrounding trees (because they block our sunlight, but only at certain hours and in certain seasons) and another tool that estimated how much sunlight each part of our roof got on every individual day of the year.  His estimate was based on an individual sunlight model of our specific home. We even compared it to real-life daily photos at certain times of day.  *That* decided our panel placement. Ipsun took care of all the permitting and the mandatory new utility meter from Dominion Energy (a digital meter that can operate in reverse, for those hours when you are sending power back to the grid).  Ipsun's installation team was respectful and professional, and in the nine months since our initial install, Herve has responded quickly to the two issues that have come up. Neither issue was Ipsun's fault, more of a "user error" situation, yet on both occasions they sent a full team out to inspect the system. Our Ipsun system also comes with a phone app that lets us track our solar production hourly, daily, weekly, etc, and lets Ipsun do monitoring from afar.  On a couple of occasions, they have proactively reached out to me to make sure everything was going okay.  (Once was to ask me to re-start the little app-monitoring device, which suggests that someone at Ipsun really is paying attention to all the data.) We have been very happy with solar in general, and very happy with Ipsun in particular.  We ended up having Tesla install a separate piece of our system (two Powerwall home-backup batteries), and while those have been good products (with solid installation and a fantastic iPhone app), Tesla's customer service has been erratic, and in a couple of cases downright weird, so I am doubly glad that we had Ipsun do our solar panel installation. One last thing about solar in general, for anyone considering it: sometimes you hear people say that the "new" solar panels these days will "pay for themselves in just a few years." That was not our expectation and it has not been our experience. Our Ipsun system consists of 18 panels rated at 350 watts (= max output in full sun), so the total system rating is 6,300 watts (6.3 kilowatts).  Before we signed our contract, Ipsun gave us a month-by-month prediction of how much electricity (solar power) it would produce.  The estimate predicted about 200 kilowatt-hours in the whole month of January (worst month) and about 700 kwh in June (best month), for a yearly predicted total of 5,900 kwh.  Their estimate has so far been very accurate (slightly low).  Dominion Energy charges us about 12 cents per kwh for grid electricity, so this solar system that cost us about $12,600 after the tax credit ($18,000 - 30%) makes about $700 of "free" electricity per *year*, and thus will take 18 years to pay for itself at current electric rates.  Be aware -- but we are very happy with our choice!

Fairfax County property tax exemption

Hey guys,
So I was planning on submitting all the documentation needed for the Fairfax County property tax exemption, but then I got a letter in the mail today from the county saying that it's already gone through! If you submitted that paperwork for me, thank you so much!
I love how well my panels are doing, even during this cloudy and rainy month. I've already had several people in my neighborhood asking questions. You guys are awesome, keep up the great work!

Solar Shading Analysis for Developer

Ipsun Power was extremely responsive from initial contact all the way to the end. I hired the firm to provide my company with a comprehensive shade analysis for real estate development project in Washington DC. The turnaround time and the quality of the report was impressive. I will surely hire them again and refer them to others.

Testimonial from happy customer in Richmond, Virginia

I have worked with Herve and have only positive things to say about our collaboration.  He provided a great deal of information about my solar carport, and was willing to help me from the very start.  Several other vendors would have nothing to do with an individual customer who wanted to do as much of the work himself as was possible.  He helped me get permission from Dominion, no small feat in itself, and advised me on what I needed specifically for my project.  You will be in excellent hands with his cooperation.

Solar enthusiast in Arlington, Virginia

I had a positive experience with Ipsun. During our first meeting, I worked with Herve to discuss solar installation options that could fit my needs. After the initial planning session, he sent me a portfolio of information that included the estimated costs, savings, and the environmental impact of several of the configurations we discussed. Herve was very responsive and provided detailed answers to my many questions. Although I am not yet ready to install solar, I felt like this was a great introduction to how I can utilize this technology and how to prepare for it. I will definitely contact Ipsun when the time is right and look forward to working with them in the future.

Squirrel guard for a solar system in Reston, VA

Herve Billiet, the owner of Ipsun Power spent significant personal time with me to describe the squirrel damage, the potential roof leakage from the poor installation, and code violations. After discussion, he offered a very fair quote to address the problems and install screening to keep out the squirrels. His installation crew reworked the entire system in a timely and clearly competent manner. I was entirely satisfied – especially with their persistence in ensuring that the squirrel screening will be effective. My recommendations to anyone owning or considering a solar installation: (1) DO consider squirrel screening if there is any nearby population of squirrels (they are aggressive, persistent, and smart), and (2) confidently enlist Ipsun Power to be your installer/support contractor.

Solar enthusiast in Leesburg, Virginia

We have had a very good experience with the guys from Ipsun Power. We have been looking to install solar panels for years now. As prices of these systems dropped a lot and the output has increased tremendously, we recently started an RFP for a solar system. We received several quotes for a system ranging from 11Kw to 25kW. Although they were not the cheapest, they were by far the most responsive, and through their personalized approach, we immediately had a good feeling with the guys from Ipsun Power. While other companies even tried to sell us solar panels on our north-faced roof, the engineer from Ipsun Power immediately found out that our roof was not suitable for solar panels and that our roof would have to be changed soon. Where others would have sold us the system and hammered us with additional costs during installation, the guys from Ipsun Power were upfront. Rare to found such an honest and ethical approach these days. Once our roof is changed, we will definitely go with Ipsun Power.
