Evolution Of Solar Panel Efficiency

New solar panels are more reliable than their predecessors and financial incentives bring their cost down considerably.

Evolution of solar panel efficiency. 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. It wasn t until 1954 that bell labs invented the first useful silicon solar panel which was about six percent efficient. Since 2009 evolution energy has installed over 1500 solar electric systems across southern california and we are still here today in order to honor our work and maintain our systems. 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.

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. The evolution of solar panels has been a slow but worthwhile undertaking. 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. This crystalline material could ultimately replace silicon in solar panels and reduce costs using simpler production.

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. Solar panel efficiency is a measurement of how much of the sun s energy a certain panel can convert into usable electricity. Evolution ultramax solar panels provide high efficiency cell technology and excellent low light performance for optimum energy savings all year round. Today solar panels can deliver at up to 22 efficiency.

Solar panel efficiency over time. There have also been ongoing efforts to make solar energy even more affordable and efficient with an emerging technology called the perovskite solar cell. The first huge step in solar panel technology came when alexandre becquerel observed the photovoltaic effect in 1839 which occurs when a material produces electric current when exposed to light. The evolution of solar power improvements in technology have made solar power more efficient and affordable than ever.
