Michigan-based Helios Solar has deployed a 535.5 kW solar array on a capped landfill in Eaton Rapids, Mich.
The array consists of 2,100 photovoltaic panels on Renusol America's CS60 ground mounts. Eaton Rapids Solar LLC will own and operate the facility, which is expected to generate 658 MWh of electricity annually for the City of Eaton Rapids' electrical utility.
Helios CEO Connor Field says the installation was challenging from an engineering perspective, given the terrain and requirements imposed by the landfill.
‘Not only was a low profile, ballasted non-penetrating mounting system required for the panels, but the"cap' covering the landfill is curved for drainage and not flat, as is the case for typical solar installations,’ Field says. ‘Our challenge was to optimize panel placement on an uneven surface to make the project economically feasible.’
