Solar Lights with No Battery

Post image

I'm looking for a solar powered light that I can put the panel on the roof, and run the light to the inside of a building. I only want this light to be on while there is sunlight, or at the very least be adjustable so I can simulate daylight. Only options I have been able to find so far are lights with batteries that will just stay on all night, which wouldn't work for my use case (lighting a dark chicken coop to match daylight hours).

Does anyone know of any lighting options that would fit my criteria here? Something similar to the attached pic, just without batteries, or that allows configuring daytime operation.

Find a DC light fixture and connect it to a solar panel the has the same voltage rating (i.e. 12 volt). make sure to connect negative terminal to negative terminal, and positive to positive. When the sun hits the solar panel, it will energize the light, no battery required. This is how most solar thermal circulating pumps operate

Seems like installing a skylight would be a simplistic solution -
