Working in two shifts in record low temperatures and stormy conditions, installers completed the ground mount array in just 36 days (during a record 60-year storm with 24 inches of snow and 60 mph gusts).
Case Study - 2.4 MW Solar Ground Mount Orange, Massachusetts
Contributed by | Creotecc Solar Mounting Systems
Facing short lead times, tight deadlines and extreme weather conditions, the project partners worked together with great efficiency to deliver a 2.4MW solar array on time for a utility client. Martifer Solar developed the project and brought Creotecc on board in late October 2012 to design and engineer the mounting system, coordinate pile testing, deliver materials and organize racking assembly.
Sunstall was brought on by Creotecc to perform pile driving, racking and panel installation, system grounding and overall site management. Working in two shifts in record low temperatures and stormy conditions, installers completed the ground mount array in just 36 days (during a record 60-year storm with 24 inches of snow and 60 mph gusts).
Adding an additional element of challenge, Sunstall had not previously installed the CREOTERRA ground mount system. With on-site support from Creotecc, they learned rapidly and within a few hours were up to speed executing fast, efficient assembly.
Most of the array was pile driven with 8 foot embedment depths. Pour-in-place ballast was used on a small portion of the site where rocky soil was an issue. Due to the flexible racking design of CREOTERRA, pile refusals were re-engineered quickly and even in extreme winter conditions deadlines were met.
