I am thinking green here. I have recently seen a couple of 15W solar
panels (15 X 2) on sale at Canadian Tire for $99.00. If I have those
hooked up to an electric generator, could I :

1) Trickle charge the generator
2) Have enough power to run some lamps, computers etc

Any suggestions would be great. Thanks

You need to do a little detective work.

How many watts does the lamp in your bedroom use?
How many watts does your computer use?
How many hours per day can you get 30 watts from your solar panels?
If you put 30 watts for one hour into a battery how many watts will come
out? Hint; It won't be 30.
What is the efficiency of converting 12 volts dc to 120 volts ac?

After you have some idea about the answers to these questions.you can
answer your own questions.

So my question is why would anyone buy a solar panel then to run a
battery inverter?


Putting aside all the tech stuff and the well made point of the cost at
the tire joint, if you run your stuff on 12v (LED lamps and use a
computer that will operate off 12v) it can be done and plenty of people
are doing that. It will however take an initial capital outlay of more
than the $99 level :-)
