shani: yes, your panel that you used for RV batteries is perfect, if you still have a charge controller, thats even better.

Don't understand why do you run lights from 4am to 9am? Doesn't it get bright around 6 am anyway and why not have the lights run let's say from 9-10 pm till 4-5 am?Hello Folks,
I think I figured it out, it works awesome and does not break the bank. Here is how you do it:
1) Find a 12v battery, deep cycle (like an old RV battery or a boat battery)
2) Get a cheap 12 v inverter, these are the ones that plug into your cigarette lighter in the car, they put 120v out. I found one for 8$
3) Get a light fixture for regular bulbs 2$
4) Get a 120v LED bulb. I use a 2w LED ceiling fan bulb, it was 12$ and puts out the equivalent of 40w
5) Get a cheap timer 4$
6) Get a solar panel, can be a small one anywhere from 20$-100$
Setup:
Solar panel charges car battery.
car battery feeds 12v to inverter.
timer sits on inverter plug and controls the early morning light.
inverter feeds 120v to Light bulb.
It has been very reliable for me and because the bulb only consumes 2w and is only on from 4 am - 9 am or so, the power consumption is very small and the solar panel can easily replenish the power.
The most expensive piece is the battery and the solar panel. but for the whole installation you can get away with well under 100$.
