Easy solar install

American Solar Sentry is a reliable company I can trust. They have been in business many years, have top ratings in the solar industry, and use quality materials. On average the cost of going solar is no different than the cost of my electric bill. Once the panels are paid off the return on investment will be fantastic. What I appreciate most is that American Sentry Solar handles all the details including permits, financing, and installation. Aside from the initial consultation, all I had to do was schedule the surveying/planning, installation, and final inspection. All went off without a hitch and in just over a month I had solar and an app on my phone where I could track how much energy my panels were producing compared to how much I was consuming. It's a very cool app and I feel good about using a clean, renewable energy source which is friendly to our increasingly precious environment.

Friendly staff

Seems it may pay for itself after 10 years or so. I had an electric bill that was approx half what it regularly was, but that was before the upgraded meter was installed. Since that was installed, it has been running in reverse more than forward, so that is a good sign. The panel installation looks good as well.

Highly Recommend American Sentry Solar!!!

I looked at about a dozen different solar panel providers and finally decided to go with American Sentry Solar. They were very responsive, have great ethos and did a great job with install. They went above and beyond by removing the old electrical wires (no longer connect or used) that a pervious contractor has just left. They were positive and also pretty quiet. I worked from home while they installed the solar panels and they didn't need to shut off the power. The panels have been great thus far and my bill has significantly decreased. We are actually exporting energy and can see in the app exactly what is happening in real time.

Great job - exactly what they said

Dealing with American Sentry has been a real pleasure. Everything they said they would do was done on time or sooner. The workmanship is great, the personnel very helpful and just a great job. The install could not have been better. It looks great and the job left everything clean and neat. I looked at less expensive alternatives, but I am quite sure that this was the right choice. I am happy to have American Sentry as my solar partner.

A very positive experience in all aspects

From the introductory visit to the final wrap-up, it was a matter of courtesy and efficiency. They are good communicators, which I value, and although the price was on the higher side, we were able to discuss and negotiate a final cost that was mutually advantageous. I have not hesitation in recommending them.

Excellent job with installation.

Fast and efficient. Gave recommendations for changes to landscape to improve solar efficiency. Installation was quick and smooth. Only complaint was with CPS Energy and the time it took to get approval for installation of the system and final approval for connection to the grid.
