Nice packaging and it works October 22, 2009
MFL (Atlanta, GA USA)
There seems to be some chance of solar panels being damaged in shipping. I was pleased with the way this item arrived. The hard edged cardboard and foam kept the unit intact.
I have not tested or used this under a load, but open circuit voltages ranged from 22VDC to 24VDC during partly sunny conditions. 22VDC was the lowest reading with the sun completely blocked by clouds. I'm waiting on the 7amp charger/controller to have some real fun. Will update soon.

 Very low power output for price and size. September 24, 2009
Jeffrey Bullard (Houston)
This should be called a battery maintainer and not a battery charger. We have a 90 Amp-hour battery on my boat and took this charger camping with us. It didn't come close to recharging the battery or keeping up with our daily power consumption. When we got home I kept it on the boat battery for 10 days and the battery still was not fully recharged.
Doing some calculations, this solar charger takes about 5 days under above average weather conditions to provide enough power to run my trolling motor for about an hour. The 15W max output is not even enough to run my electric fillet knife.
This charger is weak power and bulky in addition to expensive relative to power from the grid.
Not recommended unless used as a battery maintainer, in which case I would get a smaller and less expensive unit.
 Great for RVers September 6, 2009
H. Moylan (San Francisco, CA USA)
This is my 2nd one, I now have one for each 5th wheel RV battary, now I can last 4 days instead of 3 before recharging.
Very pleased with my purchase September 3, 2009

I am very pleased overall with my purchase. The packing was very good and very professional and the shipping was much quicker than I anticipated. After saying that, it should be obvious that the panels came to me undamaged, which is much more than I can say about the panel I tried to buy from Wally!
At about 11:00 am on my deck I got 13 volts loaded and .77 amps short circuited. I currently don't want to cut any cords to measure actual current into the battery but with my DVM in series but just using those numbers, with two panels I was getting about 19.5 watts. The sun was kind of behind some deck railing. If I went out and measured it when the sun was at the highest point in the sky, I think I would get more. However, I did not expect to get the full power rating out of these panels regardless, as I know how many variables can be in solar panels themselves, solar panel direction optimization, conditions in the sky, haze and humidity, etc.
I would buy more of these from amazon in a heart beat. In the future I may come back and update my review after I do some more precise power readings along with location optimization. For now I am generating free power(after initial purchase) and totaly sustainable in the long term without any fuel, which gives me some piece of mind looking toward natural disasters and power outages. I can do some useful things with even that small amount of power.
UPDATE as of 9/6/09. I put an ammeter in series with the two solar panels connected in parallel and measured the current. I got 1.5 amps at about 1:00pm. I have the solar panels facing south toward the sun and angled to about 20 to 30 degrees, mounted on my deck. Increasing the angle by maybe 5 degrees might be slightly better but I don't know by how much.
Right now I have the car cigarette lighter plug plugged into an old portable car jump starter during the day and by night I disconnect it and plug my 10 year old 75 watt inverter that I got from walmart at the time and never used, and then plug a hamilton bay torche(sp) light with a 20 watt compact florescent bulb(cfl). With a 6-7 hour charge, I get about 5 hours of light out of the lamp. I have no idea what the efficiency of the inverter is. It is about 10 years old, so I would assume that my inverter is not as efficient as todays models.
I just bought a black and decker electromate 400 to use and will try to get back and let everyone know how that works with this system.
Update at of 9-17-09 I have been successfully charging the Electromate plus another jump starter box through a 7 amp Sunforce charge controller for a week now and everything works great. I can charge the electrome from a depleted state in 6 hours, giving me 5 hours of light through a standard torche light with a 23 watt CFL installed. The whole system together is pretty much turn key, except that I have to tote the electromate around after a day of charging.
Update Sept 26th, 2009
Received another two panels. They came packed perfectly with no damage and work just like the first two.
Great Addition to our Motorhome August 26, 2009
W. J. Stallings (Seattle, WA United States)
I installed this panel recently, just before a week-long camping trip in Eastern Oregon. We never once had to run the generator to top off the battery the entire week. We only run lights each night for a few hours and a propane reefer. It probably also helps that we simultaneously installed a new deep cycle battery. We also purchased the recommended basic charge controller, which doesn't tell us much, other than the battery is charging.
This addition to our motorhome has been great, and it's wonderful to camp an entire week without running the generator for battery charging.
One bummer, though --- the price seems to fluctuate. It's currently $76 and we paid $90-something just a few weeks back. Jump on the current lower price if you have even a bit of interest. Such a deal!
