Are Solar Panels Efficient

So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity.

Are solar panels efficient.

The graphic below shows how dramatically solar panel performance has improved over time. The most efficient solar panels commercially available today have solar panel efficiency just under 23. Solar panel efficiency is a measure of the amount of solar energy irradiation which falls on a panel surface and is converted into electricity. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency.

Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. If a solar panel has 20 percent efficiency that means it s capable of converting 20 percent of the sunshine hitting it into electricity. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. High quality solar panels can exceed 22 efficiency in some cases and almost reach 23 but the majority of photovoltaic panels available are not above 20 efficiency.

For example if you place a panel that is 20 efficient under 1 000 watts of sunshine it will produce 200 watts of electricity. Due to the many recent advances in solar cell technology over the last 5 years average panel conversion efficiency has increased from 15 to 20. The solar panel efficiencydescribes how much sunlight is converted into electricity.
