Rooftop + Carport
Honolulu’s Hale Kewalo is an environmentally sustainable, affordable housing community, with units featuring high-efficiency air conditioners and solar water heaters. In line with this eco-friendly approach, developers of the housing community wanted to offset the building’s energy usage with a rooftop solar system and solarized carport for its tenants.
Sunspear Energy designed a state-of-the art SunPower® rooftop solar array with a dual-tilt racking system and added solar to the building’s parking structure for maximum clean energy production.
The building’s rooftop and solar carport system together produce 177,746 kilowatt hours of clean energy every year along with shaded parking for 11 vehicles. This is enough to offset 30% of the energy used for common areas such as the clubhouse, elevators and laundry facilities.
