Solar Panels Efficiency
Solar panels have come a long way in terms of efficiency. Further research is increasing the efficiency and making the cost per watt lower. In the last ten years or so that solar photovoltaics (PV) has really taken off as a renewable energy source . There are two major factors influencing the technology’s growth : the steady improvement of both solar panel cost and solar panel efficiency over time. Highlights Solar panel efficiency has dramatically improved over time, and panels continue to push new limits each year At the same time, the cost of going solar continues to drop for property owners Solar panel efficiency over time 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. It wasn’t until 1954 that Bell Labs invented the first useful silicon solar panel, which was about six percent efficient . Since then, solar PV technology has evolved at a rapid pace. Manuf
