Agreee. Simply do the math for your application. Then compare the value of the charge to your cost. Done.
Of course, everyone's value may be different. I drive around with $2000 worth of solar panels (200W) on the roof of my EV, just to make it more visibily obvious. Gets the conversations going... The energy gained (15 cents) per day is trivial, but the conversations with unbelievers is priceless.
