Sunforce 50032 15 Watt Solar Battery Charger

These are the third and fourth panels of this type that I have purchased...there are others better, but for the price, rate of return (amps), and reliability I like these best. Brian

I pull a two horse trailer. When we get to the location and I shut off my truck (Ford F250), the power is then shut to the trailer. I installed my Starter-Booster in the trailer to power lights, fans and a water pump while we are at a location.The Starter-Booster would not fully charge on the trip home, so I often had to plug it into AC to recharge it. I installed the solar panel and the regulator and it is maintaining a steady 13.5 volts.

First panel arrived broken, but Amazon quickly replaced it.

The panel is well constructed. I mounted it on the roof of the trailer between two intake / exhaust vents. The vents will give it some protection from branches that occasionally rub along the top of the trailer.

This panel works like a charm. But if you want a little more power, i would recomend the 50 Watt Solar Panel - CDT-50w 12V Crystalline PV module #31050. It comes out to be cheaper $/watt.

Saw the reviews about receiving broken units but thought I'd chance it anyways since the price was so low. The first one arrived completely smashed. Amazon was very easy about returning it and getting a replacement. Second one arrived and looked good. Small plastic pieces were found on the ground where it was unpacked. I looked the panel over and didn't see any damage. Later, when I went to plug it into a 12V adapter I realized the Sunforce 12V connector was smashed. Overall, very poor packaging. If I were to do it again, I'd pay extra $$ and buy it from a brick & mortar location like Camping World. I have no idea how it works yet since I'm still trying to fix broken parts.

I've had the Solar Charger for awhile now. For its size, it does very well. I'm a little concerned about how fragile it is. The output even in indirect sunlight is approx. 18volts. I used it with Sunforce's 7 amp regulator. Their regulator died after 2 weeks. I sent it back to them and haven't heard back. They where good about the RMA, but again. I have not heard what happened yet. The bottom line is if you want a small unit for a boat, vehicle and you have a day or two to charge the battery. This unit will do. I wish I could say the same for their regulator.
