The 4.18kW rooftop photovoltaic system was installed yesterday. The installers arrived at 7:00AM and were done by 1:00PM. Luckily a couple of extra installers arrived at 11:30AM or so which meant the system went up a bit quicker than expected. I took a lot of images and have decided to post them up in separate entries. Today I’ll post some images of the panels. We’ve got 22 Suntech STP190S-24/Ad+ (mono-crystalline 190W) panels arranged in two rows on our roof. Electrically they are connected to our inverter (a Sunny Boy 4.2kW unit) in two strings of 11. Below are some images of the panels prior to their installation on the roof.
