Batteries last a long time as well. 

Most tenants won’t replace a 9v battery in a smoke detector and your guy wants to install $15k solar?

And hopefully it doesn't require too many battery replacements/recharges.Thank you BP community.

If the mentor has an exact niche he is teaching you and it’s not just a Facebook group or some kind of training where you watch modules it might get you light years ahead.

Something that won't require constant battery changes and codes can be programmed remotely if possible.

I was not familiar with the area but did some quick research and knew that it could be in the path of progress, especially with a new Tesla battery-manufacturing plant less than a mile away.

Rumors has it that it would be Hutto or Taylor Tx since those 2 were in the running for the 5 billion Tesla battery manufacturing facility which eventually went to Nevada.

I gift 9V batteries at Christmas, for the smoke detectors.

During inspection those were missing and the tenant was not able to tell where those fire extinguishers were and also have given a vague explanation of smoke cum carbon monoxide detector not working or was making sound and due to that they had to remove it without replacing batteries.5.
