Weird how the fossil fuel industry claims it's renewables that are expensive.
My solar panels paid for themselves in 7 years (instead of the predicted 13) and our solar electricity is free now. And it runs our car.

I’ve just started along this solar panels journey in un-sunny Scotland. Their performance so far has been well beyond expectations. I’ve not used grid energy to charge the car since March. I’m pretty sure it’ll pay for itself long before the predicted 11 years.
