Here is what's wrong with it.
1. It's junk.
2. It's too small. I have cell phone
chargers that pull more power than that panel produces.
3. It's too expensive.
4. Because of 1 and 2 above, it's not worth even bothering to install it.
There is a certain minimum size below which it's not even worth the bother of running the cabling and drilling holes, etc.
these days are in the 250 - 300+ watt range, and people are installing 2 or 3 of them. There are plenty of threads around here where people are discussing good quality panels
and controllers. Outback, Midnight Solar
, and many others make good quality MPPT
controllers. The brand of panel is usually not as important on a shore installation
, but on a boat you want good quality panels that can hold up and are high efficiency to maximize the limited space onboard.
There are plenty of threads discussing the different brands of solar panels
and controllers. That one on Ebay is similar to a small solar
setup I rigged up to keep my truck batteries charged while it sits. I pop it up on the dash while it's parked, cost me $40 to throw it together.
