Top Ranked Companies


The Good

  • Respectable Partners
  • Federal and State Incentives
  • Other Solar Services

Respectable Partners

American Sentry Solar has partnered with several well-known and respected companies, including AET, Enphase Energy, Ironridge Power One, SMA, SolarEdge, SolarWorld, and Suniva, in an effort to provide its customers with high quality products and competitive prices.

Federal and State Incentives

American Sentry Solar provides quite a bit of detail on its website about the state and federal solar incentives available. Additionally, this information is broken down by county to make it simple for potential customers to see which incentives are offered in their area.

Other Solar Services

In addition to solar PV systems, American Sentry Solar also offers solar hot water heaters. In fact, the company is one of Maryland's top solar hot water heater installers. These hot water heaters are a great option to further protect your home against rising energy costs. American Sentry Solar is proudly partnered with Heliodyne and SunBandit.


The Bad

  • Lack of Payment Options
  • Limited Availability

Lack of Payment Options

Unfortunately, American Sentry Solar's payment options are limited to outright purchases and loans. While each of these options comes with a unique set of benefits, leases and Power Purchase Agreements (PPAs) are a better fit for many consumers.

Limited Availability

American Sentry Solar's services are currently only available in Maryland, so consumers who live elsewhere will not be able to do business with this company.


The Bottom Line

American Sentry Solar has many respectable partners, but the company's lack of payment options and limited availability make it difficult to appeal to a wide variety of consumer needs.

While the sales process was tedious with the first person a high pressure sign-before-I-leave kind of call, we persevered with them to get a different person out who would show us more respect. Why? Because they use domestic panels that are a both more efficient and more durable, are more aesthetically pleasing, and are installed with miciinverters on each panel to improve efficiency. The installation was fun to watch! The assembled team worked as if choreographed and cleaned up like they weren’t ever there. As for the “you have to have both people there” thing, I get it. My spouse and I just think differently. Having us both there gives them the chance to respond to each of our concerns and questions authentically.

American Sentry completed our installation in one day, on schedule, using direct employees for rack and panel installation . Electrical installation was performed by a subcontractor, and I feel that is acceptable: they focused on careful and correct work. The system will not go into service until local county inspection is final, but I am confident that it will perform as expected. They used efficient panels, made in the U.S., enphase microinverters, and Ironridge racks, creating a neat, well planned system. The installers were experienced and friendly.
