History Of Solar Panel Efficiency

Since the beginning of life on earth the sun has been the ultimate source of all energy.

History of solar panel efficiency.

While all cars have wheels a steering wheel and pedals to control it there are a wide variety of engines horsepower types of tires and brakes that all impact how efficient the car is and handles the road. The 1950s and the 1960s the solar panel as we know it today was invented in 1954 by d m. It wasn t until 1954 that bell labs invented the first useful silicon solar panel which was about six percent efficient. But the story is much larger than just that.

Since then solar pv technology has evolved at a rapid pace. A brief history of solar panels inventors have been advancing solar technology for more than a century and a half and improvements in efficiency and aesthetics keep on coming solar has had an. For a little perspective the solar cells developed at bell laboratories were operating at around 1 efficiency. A solar panel is a solar panel is a solar panel right.

Factors that affect solar panel efficiency. Chapin fuller and pearson used silicon to make a stable and reliable power source with 4 efficiency 1 the first silicon commercial solar cellwas released by hoffman electronics only a year later. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. This is above the standard rating of 37 0 for polycrystalline photovoltaic or thin film solar cells.

1980 at the university of delaware the first thin film solar cell exceeds 10 efficiency using copper sulfide cadmium sulfide. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. First solar residence in 1973 the university of delaware was responsible for constructing the first solar building. The history of solar panels can be described by becquerel s discovery of photovoltaic effect or the invention of first solar cell by chapin fuller and pearson in bell labs.

Pearson of bell laboratory. Other major events in the history of solar energy solar panels in outer space some of the earliest uses of solar technology were actually in outer space where solar was. The cells used on the vanguard 1 operated at around 10 with the most expensive and cutting edge technology. The very first solar cells invented in the 1800s were less than one percent efficient not nearly enough to make them a useful energy source.

Mono and poly solar panels commonly used in homes today operate between a 13 22 efficiency rating. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010.
