Eight Amazing Things About Solar Panels That Could Change the World

Green energy is one of the most rapidly expanding industries in the world right now due to so many people looking to do their part to help save the planet. With so much focus on solving global warming and reducing air pollution, smarter and cleaner forms of energy are being looked at very closely by scientists and consumers. There are several cool facts about solar power that can change the world.


1.The Reduction in Prices for Solar Panels

One of the biggest reasons people avoided solar power in the past is that it was too expensive and inefficient to be worth their time. Coal has been up to 90% less expensive to use as an energy source over the years, which made other options ineffective. Prices on solar panels have dropped up to 30% in some cases and have come down to the $4/watt range.

2. The Development of Solar Film

Rather than using the traditional solar panels, a few companies have started to put out solar film. Film is cheaper to make than panels because it is printed out in rolls while standard panels are manufactured like microchips. The prices on solar film seem to be coming out at roughly $2/watt, which is 50% less expensive than panels.

3.Increase in Efficiency for Panels

Solar panels typically ran at an efficiency level of around 15%, which is measured by the difference between how much sun hits the panel and how much energy comes out of it. Solar energy has become more efficient in recent years, and newer panels are putting out 22% more consistently.

4.Increase in Efficiency for Films

Thin films have greatly increased in efficiency as well. Films consistently used to have about 10% efficiency, but with improvements in technology the films have bumped up their efficiency to about 15%, which makes them more worth the money.
