Arlington is getting a little greener. Affordable housing developer AHC Inc., in partnership with Arlington County, introduced 342 solar panels at The Apex complex (2900 and 2910 S. Glebe Road) last week. The nonprofit touted the undertaking as “the largest solar panel array on a multifamily apartment building in Northern Virginia.” The 130-kilowatt installation will ultimately generate electricity to offset common area energy usage. The energy will power the lights, elevators, fitness equipment and power to the apartment community’s leasing office. “We are delighted to have the opportunity to reduce our operating expenses while also cutting back on carbon emissions,” AHC President and CEO Walter D. Webdale said in a press release. “Converting a portion of our energy source to renewables is a win for everyone – the community, our residents and for us.”
