Celebrate the longest day of the year by embracing the power of solar energy at a Summer Solstice Social on Monday, June 17 from 6:30 to 8:30 p.m. at McDonald Farm in Naperville.

The Social is co-sponsored by The Conservation Foundation and ISEA and will highlight new technologies at the Farm from this amazing renewable resource.

A presentation on the value of solar energy will be followed by a tour of The Conservation Foundation’s solar panels mounted on the barn roof and other eco-friendly features such as the wind turbine that are part of the 60-acre headquarters.

Visitors can enjoy light refreshments as they socialize with other solar enthusiasts, as they wait for the greatest show of all: the day’s sunset marking the beginning of the Earth’s rotation from its furthest point from the equator, onward toward the winter solstice when daylight is the shortest before the cycle continues again. A telescope will be available for stargazing.

This free event requires online registration. McDonald Farm is at 10S404 Knoch Knolls Rd., in Naperville.
