Committee members spent substantial time on technical specifications after the applicant described the rooftop layout. Joshua said the project would use commercial-format modules and that “there is a large supply of those 590 watt ones, and those are the ones that we'll be using.” Members asked about module type, exact wattage and panel size; the applicant explained manufacturers produce panels to a target range and that production test results yield slightly different outputs within the quoted ranges.
The committee and applicant discussed panel size and weight: the transcript records dimensions in millimeters (about 2278 x 1101 mm) and a unit weight cited as 32.7 kg. Committee members noted the panels are larger than typical residential modules (commercial ‘75-cell’ class vs residential 60-cell) and asked whether single installers could carry the panels safely; Joshua responded that weight is spread out and load per square foot remains similar to older modules.
