Is it heat or sunlight that causes increased evaporation of chlorine?

Technically, the chlorine does not evaporate. Chlorine reacts with the sodium bicarbonate to form sodium chloride and carbon dioxide. This reaction is temperature dependent. The higher the temperature, the faster the kinetics of the reactions, and the faster it depletes the chlorine.
The other factor in chlorine demand is how much use the pool gets. Naturally in the summer your pool gets more use, and the natural oil from your body, and on your chlothing, as well as an occasional accident by a toddler, also help to deplete the chlorine. Chlorine reacts with these substances to neutralize them, and the result is depleted chlorine.
And finally, if you have a pool heater and you heat the pool in the winter, you need to be concious of the chlorine level so you don't deplete it, and not know it.

What do you mean by chlorine? Often people call sodium hypochlorite solution by the incorrect name of chlorine. Chlorine is a gas but that is not likely to be what is in your pool. The NaOCl will not "evaporate" from the heat but rather decompose from the sunlight and added contaminants which it oxidizes.

Yes, if the water temperature is warmer. If your pool is heated to a constant temperature, the evap rate will not change. Most chemical reactions, including degradation of the pool chlorine, go faster at higher temperature.

Most definately. When that water gets hotter, the solubility of chlorine in the pool water goes down. Therefore it escapes into the atmosphere.

I know in the summer that chlorine use is much greater than in the winter. I live in South Florida. Chlorine is broken down by ultraviolet light. In the summer, there is more of that, for the same reason it is lighter longer.

"UK Expert" answer is correct with respect to heat. Sunlight does not cause chlorine to evaporate, but causes it to react faster therefore it is used up quicker therefore more needs to be added.

Yes it does. Water will hold more gas in solution the lower its temperature and less the higher it is. e.g. warm Coke is always flat and without bubbles.
