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

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?

answer your own questions.

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

As stated above, in places where the alternatives are more costly and/
or less 'green' than setting up an effective solar system. You suggest
that you have a generator and they can be cost effective, but are
certainly not 'green'. A micro hydro plant would likely be more costly
but can be exceedingly 'green'.
