Are solar energy systems becoming cheaper?
Solar panels are still quite costly when compared to conventional electricity. This is because the production of solar panels requires high tech equipment, still is labor intensive and requires special materials. However, every solar panel purchased makes the next one cheaper, in stark contrast to nonrenewable sources, which become scarcer and more expensive with every ton that is burned. The price has gradually been coming down in recent years because of market growth, improved materials and production processes.
