It is a unit of power that refers to the maximum production capacity of a photovoltaic (PV) module or the entire PV installation under certain conditions, known as Standard Test Conditions (STC).<\/p>\n<p>The STC conditions under which kWp is measured are defined as:<\/p>\n<ul>\n<li>Insolation of 1000 W\/m\u00b2 (i.e. a very bright sunny day).<\/li>\n<li>Module temperature of 25\u00b0C.<\/li>\n<li>Sunlight spectrum at an incidence angle of 1.5 (AM1.5, corresponding to a typical midday sunlight spectrum in Central Europe).<\/li>\n<\/ul>\n<p>For example, if a photovoltaic installation has a capacity of 5 kWp, this means that it is capable of producing up to 5 kilowatts of energy at any time under the above conditions.<\/p>\n<p>However, it is worth noting that 'standard' conditions are rarely encountered in the real world, so the actual energy production of photovoltaic panels may be lower than their nominal kWp. In actual production conditions, factors such as cloud cover, angle and direction of light, and temperature can affect the performance of the panels.<\/p>\n<p>Below are some examples of the daily performance of a photovoltaic installation on sunny days, depending on the time of year and the direction of the sun's rays (installation direction).<\/p>\n<figure id=\"attachment_13085\" aria-describedby=\"caption-attachment-13085\" style=\"width: 738px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-13085 size-full\" title=\"obtaining 9.7 kWp 17.06\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-17_06.jpg\" alt=\"\" width=\"738\" height=\"313\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-17_06.jpg 738w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-17_06-300x127.jpg 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-17_06-18x8.jpg 18w\" sizes=\"auto, (max-width: 738px) 100vw, 738px\" \/><figcaption id=\"caption-attachment-13085\" class=\"wp-caption-text\">Yields 9.7 kWp 17.06<\/figcaption><\/figure>\n<figure id=\"attachment_13083\" aria-describedby=\"caption-attachment-13083\" style=\"width: 740px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-13083\" title=\"Yields 9.5 kWp 19.06 east-west\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-19_06-wsch-zach.jpg\" alt=\"\" width=\"740\" height=\"310\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-19_06-wsch-zach.jpg 743w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-19_06-wsch-zach-300x126.jpg 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-19_06-wsch-zach-18x8.jpg 18w\" sizes=\"auto, (max-width: 740px) 100vw, 740px\" \/><figcaption id=\"caption-attachment-13083\" class=\"wp-caption-text\">Yields 9.5 kWp 19.06 east-west<\/figcaption><\/figure>\n<figure id=\"attachment_13082\" aria-describedby=\"caption-attachment-13082\" style=\"width: 734px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-13082\" title=\"Yields 9.7 kWp 19.09\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-19_09.jpg\" alt=\"\" width=\"734\" height=\"299\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-19_09.jpg 719w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-19_09-300x122.jpg 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-97kWp-19_09-18x7.jpg 18w\" sizes=\"auto, (max-width: 734px) 100vw, 734px\" \/><figcaption id=\"caption-attachment-13082\" class=\"wp-caption-text\">Yields 9.7 kWp 19.09<\/figcaption><\/figure>\n<figure id=\"attachment_13084\" aria-describedby=\"caption-attachment-13084\" style=\"width: 733px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-13084\" title=\"Yields 9.5 kWp 13.03\" src=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-13_03-wsch-zach.jpg\" alt=\"\" width=\"733\" height=\"301\" srcset=\"https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-13_03-wsch-zach.jpg 740w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-13_03-wsch-zach-300x123.jpg 300w, https:\/\/sollab.pl\/wp-content\/uploads\/2023\/09\/uzyski-95kWp-13_03-wsch-zach-18x7.jpg 18w\" sizes=\"auto, (max-width: 733px) 100vw, 733px\" \/><figcaption id=\"caption-attachment-13084\" class=\"wp-caption-text\">Yields 9.5 kWp 13.03<\/figcaption><\/figure>\n<p>The unit kWp is commonly used in the photovoltaic industry as the standard measure for determining the output of PV panels and installations.<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>kWp - what does the abbreviation stand for? kWp is an abbreviation for 'kilo Watt peak', which translated into Polish means 'kilo Watt maximum'.
