Everything has taken on a golden hue, the bougainvillea in Delhi seem to be on steroids and the birds are extra cheerful. Welcome spring! And Happy Spring Equinox!

Today is also a day to celebrate technology and here’s why- As we all remember from high school geography lessons, the Sun is at its lowest path in the sky on the Winter Solstice. After that day it progressively follows a higher and higher path through the sky each day until it is in the sky for exactly 12 hours- the Spring Equinox. On this day the Sun also rises exactly in the east and sets exactly in the west.

More sun means more solar energy.

After the Spring Equinox, the Sun still continues to follow a higher and higher path through the sky, with the days growing longer and longer, until it reaches it highest point in the sky on the Summer Solstice. And that is reason to cheer for solar photovoltaic owners.

The number of daylight hours each day has an obvious effect on a PV array’s production: More sun means more solar energy. When viewed from space, the earth’s axis has a tilt of 23.5 degrees. Because of this tilt, during the times between the spring equinox (March 20-21) and the fall equinox (approximately September 20-21), the Northern Hemisphere is actually pointing toward the sun.

Historically, we celebrate the spring equinox as a symbol of rebirth in many different forms across religions. Festivals such as Holi, Easter and St. Patrick’s Day fall around the week of March 20th each year. But our dear customers, you have another reason to celebrate now. Here’s to more sunshine and more energy!

Happy Spring Equinox, with love ~The Nerds at Sunkalp Energy
