As BigAI07 stated SAR for Public Safety will be a dead end for profit. I fly for a fire department and in our area there is no shortage of drones showing up when SAR is needed. We flew a couple of weeks ago and we most likely needed an air space coordinator as there were at least 5 drones up, all from different agencies.
Solar panels most likely will not be that great either. Drone commercial solar panel surveys have been around long enough that companies can do it in house, or have a service provider already with the hardware and software to do it better and faster than a single person with a
Mavic 2 EA. As far as offering the service for private residences, read the warranty for different panels. A lot of them will not offer warranty for defects after the initial period after install has passed. So if you find cells out or strings out, as long as the panel is generating the required power it will not be warrantied on the power guarantee. The panel is warrantied to provide a certain output that gets lower each year as the panel ages, and as long as that power is met, the warranty will not cover a new panel. Also with the whole fly by night residential solar panel industry having panel manufacturers and installers come and go, there might not even be a warranty backing the panels after several years.
Using the drone for residential building envelope could be done, but this service is not that popular and should be combined with other energy saving inspections/audits and would require training and or experience to truly offer a service with value.
Electrical work is being done more and more in house and in my pure opinion would require more than what the
Mavic 2 EA offers since it lacks full parameter settings in the limited DJI Thermal Analysis Tool as well as isotherms and the ability to set and lock your span/range. Some electrical work needs a true temperature and not an apparent temperature, and while the same sensor installed in the H20T offers the needed parameters in DJI TAT, the
Mavic 2 EA's sensor got the short end of the stick (Lack of TRFlec and humidity sucks!!!!).
You might find some work in roof moisture scans, especially if you can hook up with a roof contractor. But you really need to know roofs in so far as what types you can use a thermal sensor on and how to properly conduct your inspection.
I have seen people use their drones as a pet finder, and the thermal might help in that aspect with pet dogs.
Become a Home Inspector in your state and offer residential solar panel inspection and building envelope as an add-on, but make sure your EO insurance is okay with it, they may want a thermographer certification. Showing a prospective home buyer that the panels have a large number of bad cells and the home has missing insulation could help them haggle a better price.
