> I could build up a lot of solar panels and use the electricity to heat up an oven more than the surface of the sun, right?
Yes, this would be like using a hydroelectric dam to power a fountain that sprays higher than the initial reservoir. Machines can convert a large amount of low-quality energy into a small amount of high-quality energy, even when passive components (e.g. mirrors or pipes) cannot.
