Brooklyn Heights Solar Panels, Before and After

This month, a roof on Columbia Heights in northern Brooklyn Heights was retrofitted with solar panels. At left, workers are seen beginning the installation. At right, a few days later, the installation is complete but the sun has not risen high enough to eliminate the shadow from a taller building across the street, not shown here. However, the sunlight has still reached part of the mansard roof to the right of the solar panels. The roof where the panels have been installed will receive sunlight for much of the day, but many brownstones don’t receive sufficient sun to cover the cost of putting in solar panels.
