Hawaiian Electric approved operation of the <abbr>PV<\/abbr> system on September 30. It consists of a 133-<abbr>kW<\/abbr> <abbr>PV<\/abbr> array and 332 solar panels that are strategically placed on the unique 20,940 square-foot ballasted roof to avoid snow and ice fall from the domes.<\/p>\n<p>At high altitude, the panels will catch more photons and produce more energy than at sea-level locations. This is because sunlight atop Maunakea doesn\u2019t have to travel through as much of the Earth\u2019s atmosphere where the photons could be absorbed by something else. Having 40% less atmosphere is one feature that makes Maunakea one of the best places on Earth to conduct astronomy.<\/p>\n<p><a href=\"https:\/\/www.keckobservatory.org\/solar\/\">Read the full story at the W.
