In other words, 22.7% of all sunlight that hits the panel is converted into electricity.  <br \/>\u2192 Most Tier 1 brands are slightly less efficient than that &#8211; they\u2019re around 19.5-21.5% efficient. <\/p>\n<p>DOES SOLAR PANEL EFFICIENCY MATTER? <br \/>\u2192 The efficiency rating doesn\u2019t tell you how much electricity the panel will produce; you actually find that out from the panel\u2019s wattage rating. <br \/>\u2192 All else equal, the only advantage of a more efficient panel is that it will take up slightly less space. <br \/>\u2192 The most efficient panels generally command a huge premium. <br \/>\u2192 In most cases, it\u2019s not worth paying more for higher efficiency. <\/p>\n<p>LEARN MORE <br \/>The most efficient solar panels: We\u2019ve compiled a list of the most efficient solar panels currently available on the market: <a href=\"https:\/\/www.solarreviews.com\/blog\/what-are-the-most-efficient-solar-panels\" target=\"_blank\">https:\/\/www.solarreviews.com\/blog\/what-are-the-most-efficient-solar-panels<\/a><\/p>\n<p>Get a solar estimate: Use our advanced solar calculator to see how much solar panels for your home will cost, as well as how much money you stand to save: <a href=\"https:\/\/www.solarreviews.com\/solar-calculator\" target=\"_blank\">https:\/\/www.solarreviews.com\/solar-calculator<\/a><\/p>\n<p>SUBSCRIBE <br \/>We\u2019ll be adding plenty more videos about solar panels for homes, so make sure to hit the subscribe button. <\/p>\n<p>FOLLOW US <br \/>Facebook: <a href=\"https:\/\/www.facebook.com\/SolarReviewsCommunity\" target=\"_blank\">https:\/\/www.facebook.com\/SolarReviewsCommunity<\/a> <br \/>Twitter: <a href=\"https:\/\/twitter.com\/solarreviewscom\" target=\"_blank\">https:\/\/twitter.com\/solarreviewscom<\/a><\/p>\n<p>0:00 &#8211; Intro<br \/>0:13 &#8211; What is solar panel efficiency?<br \/>2:09 &#8211; How important is solar panel efficiency?<br \/>3:44 &#8211; Efficiency vs. Output<br \/>4:42 &#8211; When does panel efficiency matter?<br \/>5:52 &#8211; Should you pay more for high efficiency?<br \/>6:38 &#8211; Solar panel calculator<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Solar panel efficiency figures are hyped up by some vendors.
