Urban spaces are full of rooftops with the capacity to host PV systems for solar energy collection. New York City has recently recognized this and in 2015, Mayor Bill de Blasio announced his
goal of powering 100% of the citys government buildings and operations with renewable energies. The plan on how to reach this goal has been developing for the past few years. New York City Public Housing Authority (NYCHA), one of the largest housing authorities in the nation, has a lot of rooftop space for solar and in 2017, a new goal was developed to
install 25 megawatts of solar panels atop the city's public housing buildings, enough capacity to power 6,600 households. In January of 2018, the Housing Authority will start reviewing bids from companies to start the project.
