I live on a river and built a campsite on an island across from my house (the dog loves it). I bought a deep-cycle marine battery but am getting too old to lug it in and out of the canoe for charging. So I got this little panel and, so far, have not run out of juice. And it’s cheap enough so if someone steals it it’s no big tragedy. I run a laptop, TV, fluorescent light and charge my cell phone. I even have a 12v car-vac to clean the sand out of the tent.
Of course, I’m not there 95% of the time so 5 watts is probably adequate. And I don’t have to worry about overcharging. I screwed it to a big log in pretty open sun. So far, it has survived, even some small hail.
BTW, I use the power cord from an old vacuum cleaner and a 4-way 12v splitter to distribute power from the battery.

I recently ordered one of these panels (June 2007). The first one arrived shattered – the manufacturer packaging does not protect the panel much and it was inadequately packaged in the shipping box by Amazon. The replacement unit was also badly packaged for shipment.
I tested the electrical output in full sunlight and got 20V out into a 100 ohm load -> 4 watts which is pretty good.
One thing to consider though is that this product is not very rugged. The solar panel has a plastic frame but the middle is unprotected on the back (and front). So unless you handle it very carefully it is likely to break.
Someone using this on a car dashboard would need some sort of protective carrier (like those insulated pizza boxes) to protect the unit when it was not being used.
———— Update Dec 2007 —————-
Panel stopped producing electricity in November. Had to send it in to Sunforce at my expense for warrantee replacement. They promptly tested it and sent me a replacement. One thing I did notice is that the plastic housing on the unit that I returned had developed some small cracks. I am using the unit on my car dashboard to keep my battery charged.

Review by Amazon Consumer 40+ for Sunforce 50022 5-Watt Solar Battery Trickle Charger

In 2006 I took a 3 week vacation out of the country. I left my car at the airport and away I went. Upon my return, I had to have the battery boosted for 15 minutes before it would turn my car’s engine on. I have no idea what caused the drain (Sattelite Radio memory, car’s other computers, etc), but I had to do something to prevent a $50.00 boost call in the future. A coworker told me about these devices and how his brother uses them to keep his mobile home powered when parked. Higher wattage products are sold, but if all you’re doing is keeping a car battery charged, 5 watts is plenty of power for the job. No other devices (charger controllers) are needed. The charger comes with a couple of ways to hook up to the battery (direct battery terminal clips, cigarette lighter plug). I used the cigarette plug. Just plug it in to the power port, and lay the solar energy collector side face up on your dashboard. For those with heavily tinted windshields, I have no idea if the tint would cause a problem with the panel’s energy collection.
This year, after returning from another 3 week trip (and using the solar charger), my battery started better than it did before my trip to the airport!

I’m afraid I’m guilty of buying impractical transportation. Sports cars are just not made for Wisconsin winters. Fortunately I also have a 1997 Isuzu Rodeo as my winter vehicle which is very practical for winter driving. The one drawback is that left on it’s own the battery will be useless without either putting it on a charger or starting the truck every couple weeks over the summer. Between the slow drain and the harsh winters the battery is toast. I bought this charger to see how well it would work for me over the summer. I just remembered to test how well it maintained the charge on my vehicle since installing it in late April. I turned the key and my truck started right up.

Performed as stated. Keeps my deep cycle marine battery charged. When I
leave my boat after sailing for 2-3 hours my 12V LED volmeter reads system
at 11.85 volts and the next day it is charged to 12.80 after receiving sun
for 10hrs. Tops it off – trickle charge as stated.

I was looking for a few-watt solar panel for my little home project. The idea was to run a couple of ventilation fans in my house’s crawl space, using solar power. Both decent price and thorough technical specs of CDT panel have attracted me. And this product really satisfied my expectations! Panel produces current/voltage as specified. It is sturdy, easy to mount. Thanks to its sealed design, it has survived all kinds of weather during the winter – snow, ice, cold, etc. And right at this moment, it is running those fans! Highly recommended!

I have an automatic gate openner which runs on 12V battery which is charged by solar power. I was having trouble with the battery losing its charge because of trees in the area which were blocking the sun. I went to the people who installed my system and they wanted $120 just for another panel. So I began looking on the internet and found these panels. At first I was skeptical because the price seemed too low. Any way I decided to give the company a chance and my battery charging problems are solved without cutting down any trees. I just connected the new panel in parallel with the old. These are definitely high quality panels. Terry

This is simply the best 5W panel you will find – anywhere. Very rugged build quality w/ an aluminum frame and epoxy sealed tempered glass (this thing is *NEVER* coming apart!). The power output also tested better than rated. Compared to other plastic 5W products (which I’ve also owned while they worked), this is a far superior product. My next project will be much larger and I will definitely be ordering from CDT again. This was one of the better amazon.com purchases I’ve made.

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.

Have used this panel for over a month. Shipping was super quick (3 days fm purchase to mailbox fm CA to VA). Works incredibly well. Pumps out 17 volts and .3 amps. I will need another one to get me over the .48 amps I need to run a fan on a solar wood kiln. But excellent value and great product.
