Charlotte Drive Apartments


Roof Mount

Charlotte Drive Apartments in San Jose, California was a combination solar PV and ST project – one of SLP largest solar hot water projects to date. Being able to implement solar design and build both systems, SLP was able to best utilize the roof space and equipment space and streamline the build process and save on material cost. The solar thermal tank was a 21′ long by 7.5′ diameter, which was no small feat to move and put in place.

This new affordable housing community is a four-story apartment building that will offer 200 affordable multifamily apartments with 235 parking spaces. Charlotte Drive Family Apartments is part of a 295-acre Hitachi Master Planned Community which, when complete will contribute to a large development comprising of condominiums, apartments and attached town-homes. Charlotte Park is designed to ensure that it is energy-efficient and sustainable while providing its residents with high quality, affordable living.
