A quick suggestion... This thread will probably have better luck in the "fixed lighting" sub forum off of the "General Light Discussion" forum.
First, though, a couple of questions: What type/output solar panels are you using (ie: 10-100w panel)? Will you have an inverter or charger connected to a power supply, such as a battery or battery bank? What type of driver were you planning on using (probably a good question for our more experienced forum users)? What kind of light output do you want (ie: is this an outside spotlight for a large are, or a dim indoor, able to see enough to avoid tripping, or are you lighting a room for long periods?)? What area do you live in/how much sunlight do you get per day, year round (will you need a larger solar panel)?
Think of your intended uses, and post another response, if a moderator doesn't move this thread for you.
