Gridtie Solar System Final: Balance of System, Part One

This is the final balance of system video on the grid tied solar system I originally installed in October 2008. String One is 16 Mitsubishi Electric UD185MF5 poly-crystalline panels. String Two is 14 Kyocera Solar 158G panels. Combined nameplate wattage is 5172 watts @ STC. Inverter is an SMA SB4000US, rated at 4000 watts continuous AC output. As of October 2008 to date, this system has produced 6105 kwh, with a net metered utility reading of 10012 kwh. My own deration calcs put real world output at approx 3750 watts real-time, with daily summer averages of approx 20-25 KWH. This was a fully permitted self-installed system with a total price tag of $24k after rebates and incentives.

Steve when you ground the panels to each other are they grounded to a rod driven into the groung?

@depravedpuma...Ultimately the grounding does terminate at the ground rod.

@depravedpuma...Ultimately the grounding does terminate at the ground rod as you'd normally see in residential electrical.

Hi, thx for the vid...what's the sealer called?

I googled seakaflex but don't thing that that's the right spelling.

Thx in advance for your help.

@dealsaua....The sealant used is Sikaflex 291 marine adhesive/sealant. I ordered it online from Jamestown Distributers. The stuff is amazing! One could probably use in automotive applications, as in gasket bedding, as well. Thanks for watching!

Hi I was wondering if I may ask you what gauge wire you are using to go from your panels to your inverter?

Thanks Stime

@Stime64....All inter-panel wiring and panel to inverter wiring was done with 10ga USE-2, stranded. Inverter to sub-panel wiring with 10ga THHN, stranded. Thanks for watching!
