The W.M. Keck Observatory is located near the summit of Mauna Kea, on the Big Island of Hawaii. The W.M. Keck Observatory is a two-telescope observatory with two 10 meter optical/infrared telescopes. In its commitment to reduce the organization’s carbon footprint and lower the cost of energy, W.M. Keck Observatory installed a solar PV system.
M3’s involvement included design and engineering for a structural support system of a new rooftop solar array installed on the cinder roof between the two telescopes. The solar array consists of 332 solar panels that are anticipated to annually produce 259.1 MWh of energy. The system is designed to withstand high winds via a ballasted roof design.
