The fifth installation in Lancaster is scheduled to be completed Thursday.

Installed on the roof, the installation will produce 132,000 kilowatt hours of electricity annually.

That would save HDC $17,200 a year.

The panels' electricity will supply about 20 percent of the power consumed by the building's elevators, HVAC systems and offices.

The panels, installed by KC Green Energy will not be used to provide electricity to the building's apartments.

HDC funded the solar project at the Umbrella Works through its $26 million refinancing of seven properties, including that one.

The refinancing provided $8.4 million for capital improvements, such as the solar project.

HDC is considering installing solar panels at seven more of its sites.
