Marble on MPM's south facade being replaced with solar panels

MILWAUKEE (WITI) -- Part of the Milwaukee Public Museum's facade is getting a 21st century facelift!

The marble on the south facade is being replaced with 234 solar panels.

When it is finished, the Milwaukee Public Museum will be the only building in Milwaukee with a full solar wall that is generating electricity.

The wall is expected to generate over 77,000 kilowatt hours of electricity per year -- the equivalent of having 442, 60-watt light bulbs on for eight hours every day for an entire year.
