The text arrived at 6:55 am. I'm here to start the work!
We had known that it would be an early start and were already dressed and fed (multiple cups of coffee too). The crew was only 3 today. One of their colleagues did not show today and the replacement had challenges at home. So it was Luis, John and Scott who would be facing the cold weather on Monday.
Overnight, there was a dusting of snow that had fallen, probably less that 0.5". But enough to make it a little difficult.
The crew's first task was to insure that the roof could be scaled. That entailed a sweep. Selective use of salt was another alternative assist.
The small dormer roof facing the South was to be addressed first. They needed to identify rafter location and insert their flashed Quick mounts which are the secure connections to the roof rafters. They would eventually install the racking mounted to these Quick mounts.
Careful not to disturb the dish antenna!
Scott the electrician installed the main service disconnect box. This is the safety disconnect between the solar and the main power supply from ComEd, our energy supplier .
He then also installed the Solar Edge inverter (the larger white box mounted on the exterior wall). This device takes the DC generated from the photovoltaic panels and converts it to AC.
The DC from the PV panels enters the Solar Edge inverter by way of what they call "strings", or the technical groupings of the solar panels.
John and Luis are on the South section of the East roof, identifying rafters, attaching the Quick mounts
John is bringing up racking which is mounted to the Quick mounts and is the flat bed upon which the solar panel is secured.
The racking has been secured on the southern section of the East roof.
Daylight is going and the temperature outside is in the mid-twenties F. The wind is not bad, but it is not a nice environment to be working outside on a roof.
Day 2 is complete.
