Solar Thermal Shows Highest Energy Yield Per Square Metre

Submitted by Baerbel Epp on July 31, 2017
Area Yield ComparisonThe annual energy yield per square metre is much higher for solar collectors than for other renewable technologies, as the figure on the left shows. Compared to PV, solar collectors produce, on average, three times as many kilowatt-hours. Compared to biomass or bioethanol, output is in average as much as 43 times their yield. The chart shows end energy production and compares directly thermal and electric kilowatt-hours. The grey part of each bar marks the deviation in yield based on different estimates. The absolute values can be found in a table at the bottom of this article.
