I just (foolishly) answered the phone and it was a tele-marketer attempting to sell me solar panels for our home. It would cost “only” £5,000 and would be expected to pay back the investment within 5 to 7 years. This promise of course was without knowing the size of our house in order to properly size the units.
I questioned how such a device could economically work in Scotland where there was a shortage of direct sun, especially in winter, when compared to other locations in the world.
I was told “Solar panels having nothing to do with the sun. They work with Daylight! They have nothing to do with the sun!”
I hung up.
