American Sentry Solar was very easy do deal with. The installation crew and the engineers were just great. Very friendly, polite, and professional. My 12.5 KWh - 29 panel system went up in 2 days. I found only one small piece of electrical wire after a huge job of wiring, conduit, brackets, panels, etc. So, essentially no trash. The panels look clean and well installed. I chose not to wire them up from inside my attic, as there is 40 inches of new blown-in installation. This is not the norm, but they made it work just fine. it took about a month to get the panels installed and fully inspected. Everything is working great and we are over-producing (exporting) on a daily basis - Just waiting for the electric company to switch out the meter for a net meter. Can't wait!

So far so good! The scheduling staff have been great; and were very helpful in providing appointment reminders. Jonathan in sales was extremely knowledgeable. He traveled quite a distance to see us. He arrived promptly, and took all the time we needed to answer any questions. He also followed up to see if we had any further inquiries about the process. As I write this, the surveyor is on the roof to do the engineering study. He’s very nice and has been respectful of our property. He was good with our dogs too. I will make updates as we continue with the installation. 7/24/26: The installation is complete. Everything went seamlessly. We couldn’t be more pleased. Jeremy, Steve, Dean and the rest of the crew were all so professional and nice. The foreman, Dean and electrician, Jeremy were very approachable, keeping us informed throughout. Once again they were respectful of our property and great with the dogs. We highly recommend them. I will repost after a few months about our electric usage and phone monitoring , etc.

A great company to work with

11 years ago, we had American Sentry Solar come and install solar panels on our roof. The difference in our monthly electric bill was phenomenal. Recently, we had a leak in our roof, they came out for free, and told us that the problem was a ridge vent, having nothing to do with the solar. We asked them to replace the roof vent and they said they would, but there price was going to be much higher than a local company's price, because we live a two hour drive away, and we'd need to pay for travel time. How refreshing! They were protecting us from paying too much. So we found a local roofer who took care of the problem. Then, we got another leak, and the local roofer came and said "I can't fix it; the leak is under the solar panel." So we called American Sentry Solar and Kris and Mike came and fixed one leak under the solar panel for free, and fixed another leak --where a vent came through the roof above our electric fireplace--for a reasonable price. An honest and reliable company!

The sales experience was average. They offered good plans but wanted an immediate commitment. They were the last company I spoke with and I liked their offering the best, but otherwise would have said no since I wouldn’t want to commit before seeing what other companies offered. The installation was quick (2 days) and the panel sizing was great. They were able to modify the design and reduce the number of panels which is a cost savings. They didn’t do the best job of cleaning up after themselves once the installation was complete. I found small brackets and scrap wires in my yard which should have been collected by them. So far the panels are working fine and the app is straightforward.

I have been a customer since February 2026. The panels were installed in April. The pros: -Installation was completed in a day -They handled all the permitting -It was about 2 months total from signing up to getting the panels on the roof The cons: -Extremely pressuring sales pitch. The salesman said they expect a yes or no at the end of the meeting. I had received other quotes before so I was alright with singing up but this is predatory practice to allow no time to review documents after the meeting. -The crew did not get enough pictures when they installed so they had to come back out a couple weeks later take all the panels off the roof and put them back on which took a whole additional morning. -I have had many issues with the reporting system which requires going through customer service of a separate company and resetting the system yourself. There are days when the system has connection issues or when certain panels just do not generate power until you reach out to customer service. -During the sales pitch there was a delay due to their technology issue which added about a half hour to the process. -I was not informed that my current electric supplier is not net metering compatible and just found out in June. Therefore all my excess power generation for April and May will not be credited to my account. There was no discussion in the sales pitch that my supplier is not compatible and that I will lose nearly 2 months of excess solar generation. I am hoping the experience improves but as of now I certainly would have selected another company even if it meant paying more.

I recently had solar panels installed and couldn’t be happier with the experience. This company was fantastic to work with from start to finish. The team was professional, friendly, and always clear in their communication. They got the work done quickly and efficiently without sacrificing quality. The installation looks great, everything works perfectly, and the whole process was smooth and stress-free. I highly recommend them to anyone considering going solar!

Over price does not produce

1st time ever getting solar panels installed and went with American Sentry solar. My first mistake was not shopping around and my second was not educating myself on the matter. After 3 years of ownership I haven't produce enough to cover the Electric bill and the extra solar loan. One of the main reasons the loan is so over priced and I didn't realize this untill my neighbors started posting what they where quoted. For example I got 20 panels for 34k one of my neighbors got 29 panels for 17k. Yeah big difference and my grants programs never came in on time for me to put towards the loan causing my loan bill to go up to 162 a month just for the solar alone panels insane. No i would not recommend American century solar for that reason. Now installation was great and the panels work fine just dont produce. So to potential buyers be aware and shop around.

Working with American Sentry Solar was easy process start to finish. Two of our neighbor has previously purchased solar panels from American Sentry. After speaking with them and seeing how the panels were producing electricity, this made a decision to proceed. Starting with Stan Kovachki (sales) explaining the system and process to purchase, to the electric installation crew explaining their process, to the panel installation crew explaining what they would be doing. And finally Brett who completed the process by scheduling the county inspector and BGE meter switch. Very satisfied with the whole American Sentry Solar team. Panels started producing before they install crew has left the property.

Great Company to work with.

Excellent from start to finish. I will be honest, I was hesitant at first, with the initial cost, but once everything was laid out and explained it was a no brainer for us. Believe me my wife is an accountant and if the numbers made sense to her the numbers made sense period. With the warranty, the monthly saving for us between the monthly cost and our current electric bill was pretty significant. From day one with the visit with the techs everything was great and their employees were all a pleasure to have working for us. I will admit we have PPL for our provider and slowed things down a little but once they approved everything we are up and running. I would definitely recommend American Sentry Solar To anyone looking into Solar.

The phone scheduler was great and understood that as an EE, and someone that's done research on this, I had a goal in mind and just needed to chat about price and warranties offered. The sales rep, who is also their marketing manager, started our visit with a few sales faux pas: 1) He refused to take off his shoes when asked; 2) He used the bathroom. Setting those aside, his first business comment to me was, "Where's your husband?" I informed him I was the sole home owner. Then he commented, "Well....this is a mighty big house..." as if I couldn't handle my own home, alone, and/or without a man. Then he continued to insult my intelligence when I informed him I'm an electrical engineer, so I understand how solar works, and made me watch the videos on solar because I "couldn't possibly understand how solar works, it's so complicated." I tried to skip those, but he shooed my hand away from his screen. Then he dropped the bomb of DOUBLE the price for a system with less efficient panels and inverters than I was interested. I informed him that other companies were half that price, which he scoffed because of his 11 years in the business, he never heard of them. When I told him of the better panels I was interested in, he scoffed again because he also never heard of them (a leading solar panel company for the last 30 years). He eventually offered me $5k off his price, because the owner of the company is a nice guy and the chairman of the MHIC, if I put signs in my yard and told 4 friends who eventually get solar from them. Then dropped the price another $20k if I pay cash up front. He didn't even leave information with me except his price tag. I sure will tell everyone I can about this company - and to stay away! If this is the person representing your company for sales and marketing in the age of cancellation, Mr. Chairman, I wish you luck, sir.

Solar install easy from beginning to end

This was one of the easiest installs we have been through. The Sales person was very nice, not pushy. Explained everything clearly and if we had a question he didn't have the answer, he did not make something up. The crew that showed at our home was very respectful of our property and me. They cleaned up all messes that were made. Verified I was happy with the cleanup before leaving. Some may say this is pricey but I would much rather pay for Solar than the electric company. We have already seen a huge drop in our electric bill and we only had it for 1/2 month before receiving our BGE bill.

Professionals in the Trade

I spoke to three vendors and it was clear that the disclosures were vague at most. I decided to search again and put my request at the mercy of the internet. I got the robocalls and others two weeks away from scheduling a consult. American Sentry Solar called and was available that day. Jonathan was very knowledgeable and sincere. I am glad we closed that deal then. This company had to deal with my HOA, which lasted for seven months. When we got the signal from the HOA, I had my solar panels fully operational and authorized by the electric grid and local government in less than a month. I am now producing double my consumption and am very happy to be contributing to the grid and the overall environmental impact. Thanks to everyone, especially Gailan, who was with me throughout the seven-month HOA conversations. For those reading this, look no further. American Sentry Solar has the best thorough process and professionalism I have ever experienced.

Great company to deal with

We had been thinking about going solar for awhile. I saw a review a friend had posted, after getting a system from American Sentry Solar. My wife and I asked her about her experience, and she had nothing but a positive experience. So after deciding to move forward, we were contacted by ASS, after a referral. From the initial consultation I was happy with how everything was explained and all the options explained. We felt no pressure to buy, but decided it was the right offer. From then through the entire installation process was very easy. Everyone we had been in contact with was very professional and nice. All questions were answered quickly and fully. The installation was was done much quicker than I expected, and was done professionally. We are very happy with our decision, and are looking forward to lower electric bills.

Outstanding!

Bel Air, Maryland - So, I have gotten 5 estimates for solar panels for my home. I decided to go with American sentry solar because the estimate process was straight forward, they answered all my questions and did a good job at explaining the County/State/Federal Solar incentives that would apply to my project (plus they are local to me). The project was quick and again straight forward. This is the timeline of my project: 09/22/23- Started the paperwork- contract/permit/Loan etc. 10/04/23- Site planning visit- (electric panel and roofing system inspection) 10/25/23- System Install – Took about 4 hours – (The crew was outstanding) 10/31/23- Local Government (County Permit Inspection) 11/15/23- Power Company updated power meter to be compatible with the system. 11/16/23- System in full Operation I like being able to see what the system is producing to include the system status and what each solar panel is producing with the Enphase enlighten App. Now the wait to see the effects to my energy bill begins and I will update in the future. Overall, I’m very happy with the whole project and would recommend the American sentry solar team.

From great to good

We replaced our roof and installed solar panels at the same time. Installation was well organized and efficient. A window screen that was accidentally torn during installation was fixed within the week. We went from great to good when the electrical panel failed inspection twice. Both times an electrician was out the next morning and had it fixed in 10 minutes, but it takes at least 2 weeks to get the county inspector back out, so we had an extra 4 weeks of electric bill, and frustration. ADBuilders paid our additional electric bill.
