(b). Over the long term, solar energy is the cheapest way to power your property. But it requires a significant up-front investment that slowly pays back over time.

Everyone loves the idea of saving money on energy bills. But when someone puts a quote in your hands for a system that costs more than a new car, you might start to have your doubts…

(c). Black absorbs light while white reflects light.

Light contains/is thermal energy (heat) so black objects will heat up faster than white objects. People want the solar oven to get hot while they want their houses to remain cool.
