I've been using something similar to this https://www.amazon.co.uk/Ring-RSP600-Solar-Tricle-Charger/dp/B00C9ZLSE6 on my Porsche for over a year now. So yes, you can use the light. If you have windows it's OK, if not, leave the light on.
It strikes me that converting electricity into illumination from an incandescent light bulb then back into electricity via a solar panel would not be the absolute last word in efficiency.
