Solar Powered LED Circuit (with battery)

[Scalamoosh]

Hi, I am wanting to create a 15xLED circuit powered by a solar panel. However, I am wanting the solar panel to charge a battery/capacitor (during the day) and power the LEDs (via a switch, not an LDR) at night.

I have looked around the internet, and found this page: https://www.evilmadscientist.com/article.php/solar
This page gives a few examples of schematics, but I have no idea how to step-up the circuits for a bigger battery, and a bigger solar panel.

Could anyone on here help me with the schematics for what I am wanting to create?

If you need any more information. please feel free to ask.

Technical Stuff:
LED: 15 x LEDs (Orange) with ratings of 30mA, 2.0-2.2V
Solar Panel: I do not have the exact output of the solar panel, as it was given to me from a friend, and there was no markings, or packaging with it. I have tested it with a multimeter though and the reading are: 18.2v and 0.34mA (display read 0.34 on setting 20mA DC).
NOTE: These reading were taken this morning, and it happens to be a very overcast day, so the readings would normally be higher, but this should give a rough guideline.

Any help would be greatly appreciated.

you have roughly 6mw of output power on your panel... Try first to make a characterization of your panel ... Full sunlight at 12 hours heading south with sun rays perpendicular to your panel --> take V ; add different loads --> measure V an I

OK, I will try it tomorrow midday. What sort of load are you talking about? I haven't really got anything to wire up to it, until I have created the circuit. I thought testing it with just a multimeter would be OK?

OK, I have just re-tested the solar panel, on a sunny day, at 12 noon, facing south.

The readings are: 22v 69mA

Anyone? No... Really?
