I added a small solar panel to my 2025 CX-5. Newer cars tend to have a lot of parasitic loads drawing on the battery while the car is parked---and Mazda is no exception to this trend.
I drive my car perhaps only twice a week---and then put on extra miles to bring the engine up to operating temperature. I considered several methods of reducing parasitic loads, but decided instead to add some solar charging. I park on the street in front of my house... and the car always faces South.

The panel included several methods of connecting to the car---including an OBT2 port connector and a "cigarette lighter" plug. I tried both methods, but settled on using the (always hot) 12-volt power connection in the armrest between the driver and passenger seats. I covered the red/black power cord with some

The solar panel maintains the Mazda's battery voltage very well... and does not draw undue attention to itself.
