Like me you've probably seen those cheap looking (but not actually that cheap) solar cells in places like Maplins and asked yourself if it is ever worth the bother given the teeny outputs.
This is another one of those products, which is the cheapest I've seen yet for a quality item. Yes, it's made in the Far East but with some US engineering this really is the one to go for.
Its rated at 5.0W which equates to 410mA in current terms at 12V - not, for one minute, that you'll get that on the average UK overcast day of course. Obviously it's outdoor rated at IP65, and there is no need for a separate regulator or reverse current device which I liked a lot. It's also fine for wet, gel, MF & AGM batteries so you needn't worry where it goes. I was surprised to see it able to run my LED lighting even with the battery disconnected on a bright day, albeit at reduced brightness.
What I've done is mount it on a pole at the site where I store my trailer tent, cut off the original plugs and connected a trailer type 'S' plug to the end. So when my trailer is parked up, the battery (80aH) gets a top up off the solar. I might even be able to connect an alarm system to it (perhaps based a Bentley universal alarm board that uses approx 5-10mA in standby) in the future without worrying about the battery drain. Good stuff indeed.
The only thing that lets it down is the lack of a pole mount, or rubber feet for temporary use.
