Please re-watch the video from Lesson 1: PL.₁ Then, answer the following questions related to the lesson topics. Read below for video transcript of "How Solar Works."/nHow Solar Works As shown in the video, a solar array can be installed on a rooftop for residential application. After all mechanical holding structures are installed on the roof, the solar panels can be fastened to it [0.05-0.10]. When the sun shines on PV panels, photons are converted into electrons that form electrical current when it moves towards the circuit terminals [0.11-0.20]. The electrical DC current then travels through conduits down towards a power conditioning unit (AKA inverter) [0.21- 0.29]. The current is converted to AC electrical current and travels through an AC disconnect box [0.30-0.33]. When the AC current exits the disconnect box, it goes through a PV production meter to count energy generated [0.30-0.36]. After that, the current is backfed to the lower side of the Main distribution panel (DP), where all load circuits are connected, through a protection breakers [0.37-0.39]. When the PV array is generating power, the load circuits draw power from the PV array instead of the grid [0.40-0.43]. While the PV array is generating power, the monitoring device is transmitting the data to an online portfolio, where clients can see their instantaneous PV array performance online [0.44-0.51]. Finally, the > excess energy generated from the PV array is returned to the utility grid [0.52-0.58]./nFrom owner's perspective, Roof mount systems are preferred because : The installation utilizes unused spaces O The BOS cost are minimal O The system is more secure (not easy access to theft) O All of the above
