PV buttress at Locust Hill / 1. Aerial view looking northwest

Four photovoltaic arrays (each 13' x 16') will track the sun 58' above Locust Hill, the demonstration underground building designed by Malcolm Wells, still under construction at Raven Rocks. The west tower is finished and awaits the installation of its 26 PV panels. The tower for a second array, a prototype design William Mook, will go up soon.
