Great Product
Customer Rating: 




This 5W panel performs great. It is everything the description says. Very easy to install. I had a charge regulator already, so it was easy for me to connect this heavy duty panel to power my weather station.
I had tried hooking up my own solar panel array by piecing together smaller flimsier solar panels with disappointing results. With 6 200mA panels, I still wasn't getting enough juice. A multimeter revealed that the total output was 200 mA for all 6! (3 sets of 2 9V panels in parallel).
With just this one CDT panel I'm getting more than enough power. The already installed heavy gauge pre-tinned wires are about a foot long, so I ended up having to connect some additional wire to them. I was just thankful the wires were already connected (very securely) to the panel already. My past experiences with connecting wires to solar panels has been very frustrating.
This solar panel has an internal diode to prevent back flow of current when it's dark or cloudy. It's hard to believe the excellent quality I got for the price.
5w panel sturdy; weather resistant (sealed)

I just received the 5 w panel. I find that it is very sturdy. It is under a glass panel and surrounded by aluminum sides. The two wires are about 12 inches. In full sunlight, on a clear day, I measured about .32A (that's 320mA). If you cover one cell in the panel, the current drops to less than a few mA. So avoid shadows.
The aluminum frame has predrilled holes and comes with strait brackets (two holes).
When I placed the panel on the dash board of my car, the current measured was 180mA.
So, I plan on mounting them on top of my car. I think it has a blocking diode inside the panel.
The panel is sealed with what looks like caulking.
I didn't understand the price until I received the product.

Its been a year and change (7/22/2008).
The solar panel sits out in the parking lot in the hot summer and in the freezing cold winter.
I paired the panel with a 12V 26AH (26000mAH) AGM SLA battery (Lead Acid). It powers small electronics like a clock, mp3 players, cell phone charger, GPS, etc... Its on a separate circuit from the rest of the car.
So far this experiment has been working out fine. I got my Garman GPS powered by the charged battery for about an hour a day and my mp3 player for at least two hours a day while I'm driving. I've been trying to drain that battery, but solar panel keeps it topped off.
Not bad for the 10 hours of low angle sunlight I get here in the north.
Excellent product if you know what to do with it.
