Evolution of solar panel efficiency.

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. This is done by capturing the electrical current generated when sunshine interacts with the solar cells in the panel and is transferred through the wiring and busbars to be converted into ac alternating current energy. It wasn t until 1954 that bell labs invented the first useful silicon solar panel which was about six percent efficient. There have also been ongoing efforts to make solar energy even more affordable and efficient with an emerging technology called the perovskite solar cell.

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. Solar panel efficiency over time. Solar panel efficiency is a measurement of how much of the sun s energy a certain panel can convert into usable electricity. The evolution of solar power improvements in technology have made solar power more efficient and affordable than ever.

This crystalline material could ultimately replace silicon in solar panels and reduce costs using simpler production. Today solar panels can deliver at up to 22 efficiency. This is a vital factor in panel technology because the more energy a solar panel can absorb the more efficient the panel becomes at harnessing solar energy. The efficiency of the solar cells used in a photovoltaic system in combination with latitude and climate determines the annual energy output of the system.

For example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200 kwh yr at standard test conditions but it can produce more when the sun. New solar panels are more reliable than their predecessors and financial incentives bring their cost down considerably. Evolution ultramax solar panels provide high efficiency cell technology and excellent low light performance for optimum energy savings all year round. The evolution of solar panels has been a slow but worthwhile undertaking.
