Latest bad review thumbs down

Sara | Elkton, Maryland | 02/07/2023

Aggressive sales, Extreme Price

This company runs on high pressure sales tactics and over inflated prices. Their strategy is to corner you in your house, presenting their offer as extremely marked down (45k to 35k) with sales incentives that are available if you sign up right now. After signing their contract, I got competing bids from other companies and received quotes of 22k for the same exact KwH set up for my house with higher quality panels. A.S.S. also dodged my questions about the cost, and radio silenced me when I decided to cancel my contract within my legal window. I would not recommend this company at all. Please do your research and get a wide variety of quotes before moving forward with a solar project.

I cannot express how good of a job American Sentry Solar did. The crew that they sent out today was super friendly and knowledgeable. I’m glad the money that I would be putting towards my energy bill is now going towards something that I can profit from along with bringing my home value up.

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.

Professional, Prompt and Productive

The team was amazing - left everything neat and clean and working! They are the nicest people. Most importantly, they work for the company and are NOT hired contractors hired on the side. Thus, they care about the job and getting it done correctly and efficiently!

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.

Terrific company. Minor technical problem with installation. I had some shadowing due to a dormer. They immediately re-positioned panel and took care of roof where panel had been. Production greatly improved.

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.

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.
