GroSolar

The 18MW DC groSolar Community Solar Portfolio consists of is 10 – 2MW AC solar systems all on the Annapolis Landfill. ARM Group was awarded the geotechnical, electrical, structural and civil engineer of record services in 2017. The groSolar portfolio will be installed on the capped landfill and the projects will be part of the Maryland Community Solar Program for brownfield sites. The design and construction of the site were implemented in a manner that would overcome the geotechnical and electrical hurdles presented at the site. The groSolar portfolio was purchased by from another solar developer and required numerous electrical and civil redesigns.

ARM has coordinated with Baltimore Gas and Electric and groSolar to upgrade each project by increasing the solar module wattage, and by changing the racking and medium voltage equipment on all the sites. To support the equipment loads, and overcome the geotechnical landfill membrane conditions ARM specially designed the foundations and racking systems utilizing a pre-cast ballasted racking system. As the Engineer of Record, ARM also has coordinated with the MDE and Township, performed production and shading analysis, electrical, geotechnical and civil site inspections, arch-flash studies, voltage drop calculations and much more.
