I'm writing this review before my solar project has concluded. I'll amend this review as necessary as we finish. I initially contacted Prospect Solar almost a year ago, in gathering information and quotes for a solar installation on my new house. Prospect immediately stood out. They weren't a sales front for a separate installer, they used all their own crews, they were a roofing company with a long reputation in DC, the sales rep was knowledgeable and gave me more and different information than any of the others... they were more expensive, but I felt like I was getting a dependable crew on my roof, a better experience, a higher end product, and dealing with a known, respected company. Sold. Signed. This was in June of 2022. It's now June of 2023, and while I finally have solar panels up on my roof as of a few weeks ago (installation was May 17-19) they aren't approved or turned on yet. I'm not optimistic they'll be switched on this calendar year (ie, in the next 6 months), if that gives you an idea of my overall experience. Pretty much immediately after signing the contract, my experience went downhill. I was passed from my excellent sales rep to a project manager, and that was when the red flags started popping up. One of the first red flags was that I was never explicitly told about the payment schedule, and the demand for the first payment was sprung on me when someone came out for my initial site survey. The payment schedule may have been buried in the contract, but it really feels like this is something that should be explicitly discussed with a client. So it was a little jarring to write a check for thousands of dollars unexpectedly, but whatever. A red flag, but partially my fault maybe, so okay. Sure. After the site survey, communication slowed to a crawl. We spent July through October (so 3-4 months) going back and forth on my roof and permits. This was mostly just dead air on Prospect's end; I wouldn't hear anything from them for weeks at a time, until I sent a frustrated email. This would turn out to be a pattern that would cost months of delay. Then, in October, Prospect revealed that there was some kind of supply chain issue with the manufacturer in China that was preventing my project from moving forward, along with many others. Months of false promises about phantom deliveries, apologies, delays, excuses, etc. later, and suddenly, Prospect has enough of a slightly different panel to service all of its delayed projects. Okay, great? We're now into January of 2023. Six months have gone by, I've paid tens of thousands of dollars, and all I've got is months of radio silence, a hole in my attic, useless permits that have to be re-done because of the change in panels, and nothing else. Communication issues had gotten worse at this point. They'd assure me they were working on permits or whatever, but I wouldn't hear anything for literally months at a time. When I'd email in and ask what the status was, suddenly, progress appeared! It became very obvious that either nothing was getting done, or it was getting done, but stalling out when moving from one step to the next until I sent an angry email and poked the nest. I received a concerned phone call from my sales rep about the lack of communication and I was assured communication would improve, and indeed I was kept more in the loop... for about two weeks. Then it died down again. I finally got details about an impending installation in May, and the installers came out to do my roof a few weeks ago. The crew that did the work was great. Totally professional, got it done in 3 days, a delight to have work on my home. Can't really say for sure how the install went, because I haven't seen any photos or been given any details about the installation. Once again, radio silence from the office. Clearly there's a huge disconnect between the crews out in the field and the folks in the office. Not surprising. So here we are, in June of 2023, a year after I signed my contract. I have panels on my roof (to my surprise), but no inspection scheduled, and Pepco has to do upgrades to the pole outside my house before I can switch my panels on. I have no idea when that's going to happen, and no confidence in Prospect's ability to chase down Pepco and get them to do that work on any kind of a timetable. Waiting a year is bad, but if I'd gotten adequate updates and been kept in the loop the entire time, I might feel differently. I understand Covid, supply chain woes, etc. have thrown things for a loop. But it's very clear to me that I'm not a priority, nor is my project being handled in any kind of professional manner. I email in and complain, and suddenly, things happen and we move along to the next step. They apologize, assure me they hear my concerns, then I'm forgotten about and another month goes by without any kind of update, and we repeat the cycle. Avoid this company at all costs. Stay tuned. Will update. read more

We just switched our solar PVs to "On" today! What a great experience Prospect Solar put together for our project. We signed our contract April 11, installation began May 23 completed in three days. Inspections by the County of Loudoun followed smartly, and then inspections and installation of a new meter by NOVEC. Eight weeks: that's awesome. The Prospect Solar team has been responsive, helpful, timely, very knowledgeable, and capable. We're glad to be doing our part to reduce the burden on Mother Earth, and appreciate the expertise of the Prospect Solar installers who got us there. BTW, we got eight bids before we chose Prospect. It was a process that helped hone our knowledge overall and helped us value the latest technology at excellent value. Plus, we're on the NOVEC grid, and we felt the NOVEC/Prospect partnership would be beneficial. We made the best choice. read more

Just got my new solar panels commissioned and they are working beautifully! Prospect Solar did a very professional job. The installation was clean, safe, and efficient. They do a very good job communicating - I felt like I knew exactly where we were in the process the entire time. They arranged for all of the planning, design, permitting, and utility coordination. All I had to do was sign documents to authorize - easy. They explained clearly how large the solar system would be and what impact that would likely have on my utility bills going forward. I installed a separate monitoring system to give me additional feedback on my electrical load and production; it says my solar power peak production is exactly what was planned. Good to know for sure! They also have roots as a roofing company, which was important to me as this system is attached to my relatively new roof. I wanted to make sure it was in safe hands. So far, so good. read more

Prospect Solar installed my 7.2 kW system in October. We found them through their partnership with Novec, and with their financing partners, they answered any and all questions I had leading up to the decision to purchase. System design, specs, efficiencies, comparisons of panels, and when I nerd out on a topic I go deep in the weeds. Their knowledgeable staff made it a smooth process from start to finish. The installation took two days, as promised, and though I did have to remind people to mask up a bit more than I felt I should have, hopefully they've explained the gravity of the situation to the crews better by now. While other friends I know who installed solar told me about having to wait weeks or months for the necessary inspections following installation, Prospect Solar was able to take all the necessary follow-up steps with the utility and inspectors so quickly I was up and online the next week. (This is unusual, don't get mad if it takes a little longer, I think we had some stars align.) Great work, quality products, solid warranties through SunPower but also Prospect Solar itself. If I move or decide to rent out this house, shortly after move-in, they'll be getting a call from me. Keep up the good work. read more

It was a pleasure working with Prospect Solar. Everyone we interacted with on their team was professional and responsive. Our project was more complicated than most given that we were building a new home and this was our builder's first experience with solar. The Prospect team handled it like pros, making the time to educate our builder and carefully coordinate scheduling throughout the installation and inspection processes. read more

Prospect Solar - Sunpower panels on a new construction house installed by Prospect Solar - Solar Installation Near Me - Sterling, Virginia

Prospect solar installed my 12.7kw system in Aug 2019. I love my solar system and its very addicting to see how much power is generating. Also I love that I have more self-reliance and not dependent on grid energy. Prospect was great. Very professional and effcient. The one thing I should warn that if you live in VA- if your system is 15KW or higher - dominion will charge a stand by fee. It is not easy to understand how they get the fee as they manually calculate. So keep you system at 14.9kw or below in VA. This standby fee can really detract from your savings. The other good news is that if you live in Fairfax county you get deduct part of the costs of your system from your property tax... You can google it. It was a signficant saving. read more

For the 15 years I lived in Burke, owing to the abundance of trees surrounding me I could only dream of having solar panels installed since the trees did a great job of protecting us from the Sun's rays -- while at the same time dashing any hopes of having solar. When I moved to a single-family home in Stone Ridge 15 months ago, the idea of installing solar panels shifted from the back burner to one of high prominence since my house has an unobstructed view of the Sun. I did due diligence and a considerable amount of research before deciding to go with a local company -- Prospect Solar (118 Acacia Lane, Sterling, Virginia 20166; ph.: (703) 444-2447; website: https://www.prospectsolar.com). Initial discussions began late last year with Martin J., a Prospect Solar representative. Martin came to my house and we had an in-depth discussion about solar panels. If I have learned anything in life, it is that you have to ask many questions before making a major decision or embarking upon a life-changing venture. Installing solar panels definitely qualifies as both a major decision and a life-changing venture. Martin did an admirable job answering all my questions and anticipated ones I had not even thought of asking. From pre-installation to commissioning, my "Prospect Solar" Inbox boasts over 100 messages exchanged between me and representatives of Prospect Solar, primarily with Martin J. (Residential Sales) and Angeline H. (Project Manager for my project), not to mention phone calls and site visits. There are many, many aspects of the solar panel mindset which need to be taken into consideration, and to do them justice would require many pages of explanation. That would run to a long version, but this is a short review, not a PhD. dissertation, and so this is very much the short version. Do take advantage of Prospect Solar's free estimate, which involves a site visit and preliminary work by the company's engineering unit. In my case, the job involved the installation of 23 solar panels on the east, west and south sections of the roof. Unfortunately, I was not able to take advantage of the largest section of the roof because it is north-facing. Martin honestly admitted that his company could install panels on the north-facing roof section, but the effect would be almost entirely cosmetic and would involve an increase in productivity of only 1%-2%. Not worth it. To take my example, the prediction is that I will be able to offset my electricity bill by something on the order of 62%, a sizable savings. Keep in mind, though, that this is based on a very conservative figure of a yearly daily average of 5 hours of daylight. When I heard this, I immediately did some calculations. A "quick and dirty" method of averaging the two solstices gives us a yearly daily average of more than 12 hours of daylight. As a result, I look forward to the company's prediction of 62% actually being considerably higher than that. Time will tell. Many people will be put off by the cost of installing a solar system. The technology is still quite new -- and admittedly comes at a premium. However, there are two payment options. For the more well-heeled, there is the cash option. Alternatively, the cost can be spread out over x number of years at what seems like an artificially-low interest rate. (Could this be a subtle government incentive?) And then there is the tax credit. It is currently at 26%, but unless the new administration changes things, the percentage will reduce each year you delay installing solar. My highly professional installation took a full two days. During no time was I without electricity. The Architectural Review Board of the Stone Ridge Homeowners Association was very supportive of my application, which was approved on the first submission. I have no hesitation whatsoever in giving Prospect Solar the highest possible recommendation: five brilliant stars! Disclaimer: I am not related to anyone who works for Prospect Solar, nor do I know anyone in the company apart from the few individuals I came into contact with during the process of designing and installing a system of solar panels. I have received no remuneration, either monetary or any other form, for writing this review. Steve Marder read more

Prospect Solar installed my 19-panel solar array on time and on one of the hottest days of the summer. They worked with the City of Alexandria to get all the permits and inspections, which made it easy for me. The system has worked great, producing exactly what was predicted. My electric bill is $8.12/month. read more

We installed a Prospect system last Fall and couldn't be more pleased. Our sales guy Wyatt was great, easy to to talk to and responsive when we had a question. The only slightly problematic part of the install was the permitting, in the City of Fairfax. The delay was not Prospect's fault, and as soon as the permits were ready they were on top of the installation. We installed 16 360 watt panels, and absolutely love it. Right now we are cranking out 4Kw. The Sunpower app and control electronics are great, and easy to review. Prospect also gave us a detailed operating manual, which included engineering and sales info, and detailed drawings. Prospect Solar is a great outfit with great people and you will NOT go wrong if you choose them. read more

Solid professional business. Calls dealt with in a vey timely manner and my solar array is purring along nicely. Except for the bad weather months, we have been generating lots of electricity. read more
