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.

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.

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.

Excellent Service

Everyone that worked for this company was very helpful. They all completed their work quickly and well. I have not had any important problems. When their equipment told them that a cell was not working they immediately came and fixed it. I am so happy with the service provided by this company that I have already asked them to do some other work for me.

Great experience, beginning to end.

I had an excellent experience with American Sentry Solar. The initial estimate with Jonathan Solovey was honest and straightforward. The installation team consisting of Casey Bottiger, Matt Tennis, Matt Tobin, Kevin Dawson, and Chad Williams, was very professional and friendly. They worked well and efficiently installing my system in under 6 hours explaining what they were doing and answering any questions I had. The final system is functioning and looks great. I'm extremely pleased with my entire experience with American Sentry Solar.
