Darkness in Alaska In the far north the sun does actually set in the winter and not come up for about three months. And in the summer, it comes up and doesn’t set for about three months. In the south-central part of the state, around Anchorage where most of the population is, we have about 5 hours of daylight in the darkest months. In the summer we have about 5 hours of twilight — it never really gets dark.

Monday was the first day of summer, but it is NOT the longest day The first day of winter you'll hear it's the shortest day of the year and for summer it's the opposite. But what we should actually be saying is: Happy longest amount of daylight day!. It sounds silly, but it's a better reflection of day. A day only has 24 hours, so today can't be any longer than tomorrow. The sun rises at 6:13 a.m. here on the summer solstice and sets at 9:08 p.m. That's 14 hours and 55 minutes of daylight to enjoy! After Monday, the sunrise will continue getting a little later and the sunset a little earlier. Eventually by the winter solstice, we'll have a measly nine hours and 25 minutes of daylight. We aren't trying the change the world here. But you better believe if one of our meteorologists says Monday is the longest day of the year on air, we immediately get called out via email or social media.

Alaska Daylight Hours Calculator Find out when the sun will rise and set during your Alaska trip. Our summer days are long while winter days are short. As you go further north during your trip to Alaska, the summer days get even longer. In the Far North, the sun doesn't set for months! Some people think Alaska has less sunlight than other places. The opposite is true. Averaged over an entire year, Alaska gets 10-17 minutes more daylight per day than the rest of the country. If you include civil twilight, Alaska gets 40 minutes more light on average than the rest of the country. Even during those months of the year when Alaska has the same daylight hours as other locations, the days seem longer.

About Our Seasons During the equinoxes, sunlight strikes perpendicular to the surface at Earth's equator. All locations on Earth, regardless of latitude, experience 12 hours of daylight and 12 hours of darkness. The spring equinox marks the change from 24 hours of darkness to 24 hours of daylight at Earth's poles .

America's Solar Energy Potential Therefore, a one square yard area exposed to continuous direct sunlight [in an optimal geographical location] for six hours will have received 6 hours x 833 watts = 4,998 watt-hours of solar energy during the course of a day.

- The savings are small in percentage terms, but in absolute terms, they added up to 1.3 billion kilowatt-hours — enough to power about 122,000 average U.S. homes for a year. These savings come in the summer months of daylight saving time, not the Standard Time months we are about to enter. The time change actually is rooted in an agricultural society, Earnest said. The idea of extending daylight was meant to provide more time to work in the fields.

Solar panels: Finally affordable! 1 If you use 900 kWh/mo., that's 900 kWh / 30.4 days per month = 29.6 kWh/day.  Figure how many kWh you need to generate each hour. From the map above you can see that if you live in a yellow area that you'll get 5 to 6 hours of peak sun per day on average. We'll call that 5 hours/day to be conservative.

Solar panels: Finally affordable! Annual average daily solar radiation per month (using a flat-plate collector facing south at a fixed tilt equal to the latitude of the site, which maximizes input). The scale is the same for peak sunlight hours. For example, yellow-shaded areas get an average of 5 to 6 hours of peak sun per day.

- Time (DDST) would probably save marginal amounts of electricity — around 3400 MegaWatt. hours (MWh) a day in winter (one half of one percent of winter electricity use) and around. 1500 MWh a day during the summer season (one fifth of one percent of summer-season use). Winter DST would cut winter peak electricity use by around 1100 MW on average, or 3.4. percent.

How much does daylight time increase after Dec. 21? after Jan. 7? Following December 21, as the sunrise slowly arrives later over those 17 days, we add, at best, a mere minute of daylight to each day at sunset. By January 7, though, we're adding a full two minutes each day to the daylight hours --one at sunrise and one at sunset. Following January 7, the days are getting longer twice as fast as they were between December 21 and January 7. By January 7 each year, it's like we're finally emerging from the Dark Ages, despite the achronistic technology north and east of town.

About Day and Night In contrast, the north pole receives 24 hours of daylight for a few months in the summer and total darkness for months in the winter. These two annual times of light and dark are separated by a long sunrise and a long sunset. Earth rotates on its axis; this causes us to experience day and night.
