This case involves the unpaid construction of a solar panel facility in Washington state. The facility and its solar panel modules experienced damage due to a snowstorm several months after the construction of the commercial utility project began. After the facility was repaired, the facility elected not to pay the construction company in full due to alleged construction and workmanship issues. The construction company then sued the facility for lack of payment and the owner of the facility countersued regarding alleged workmanship issues. An expert in solar panels installation and tracker systems was sought to comment on the process, including transportation, delivery, handling, and installation.
