A 15 Watt Solar Panel:

Can a 15 Watt solar panel do what it should, or will it just let you down?

Ahhhhh, the eternal question of a person considering a solar panel of miniature proportions. Considering the fact that SunPower and Schuco have solar panels that produce 315 Watts and 350 Watts of power respectively, I think it's also safe to say that a 15 Watter does not belong in the 'large' category of solar modules. |
If a 1 Watt panel is extra small and a 350 Watt panel is extra large, a medium sized panel would have to fall into the range of the 85 Watt KC 85T from Kyocera Solar or the 120 Watt MF-120 module by Mitsubishi Solar.
This definitely confirms that a 15 Watt solar panel belongs in the small category. Let's just say it is in the middle section of the small solar panel category.
Now what kind of power can we expect from this "middle of the small category" kind of solar panel?
A simple rule of thumb to remember is that a 15 Watt module should provide about 1 amp per hour in direct sunlight.
This kind of power can help you keep the batteries charged on your:
If you're planning on using your panel for battery charging you might
want to look for one that comes as part of a kit that includes a 12V car
adapter, a length of wire, and battery clamps.
Also, it is recommended that you use a charge controller with a panel this size to prevent overcharging and discharging.
Other ways you can put a 15 Watt panel to work include powering up a deer feeder or an electric fence.
Now
that you've got some ideas for what you can do with your 15 Watt solar
panel, you're probably starting to wonder just how much one of these
gadgets will cost you.
Of course there is quite a range of prices
available and they are changing all the time (welcome to the wacky
world of the cost
of solar panels). Nevertheless, the following results from a
few dozen internet searches should give you a good starting point:
