Why are solar panels so expensive?

Solar panel prices have fallen by approximately 20% every time global capacity has doubled, following a trend known as Wright's Law. Solar panels can convert 22% of sunlight into electricity, whereas the first solar panels could only convert 1-2% into electricity. This has helped drive down costs as the panels are more efficient.
