Solar Panels Arrived
The solar panels arrived yesterday 9-30-13 by UPS, 10 days after ordering. The boxes were beat up and looked like I’d have some broken glass inside but they were fine. Panel size: 40.8 x 20.7 x 1.38, Weight: 16.3 lbs. each. First impression is these are a good quality panel and well worth the price of $149.00 each, delivered free.
The protective cardboard shipping sheet that was on top of the glass.
An edge view of the cardboard shows it is ½ inch thick honeycomb structure.
Here’s what the cells look like. They are actually black but the flash of the camera makes them show up blue.
The rear side of the panels.
Panel connection box and pig tails. Users have no access to the panels connection box just the pig tail connector.
I wanted to test the voltage of the panels because if they were bad I could send them back right away. So I leaned them against the windshield to get some sun on them. Don’t make fun of my paint job, typical of GM. A new paint job will happen after the panels are installed. My must do list is getting too large and just trying to keep up is wearing me out!
The open circuit voltage spec’s are 22.0 volts.
My reading was 20.6 volts however it was a hazy sky and the panels were not angle optimized towards the sun. I have no doubt they will perform to their specifications.
I had to order the mating “MC4” power cable connectors from Amazon ($24.00).
Now I need to figure out how to mount the panels to the roof…
More to come!
