I can't speak about the potential nature of the problem, but I can assure you it's impossible to provide too much natural light indoors to this plant, and most succulents. The more, the better. You can't really sunburn indoor succulents (provided they aren't coming right out of deep shade) because regular window glass cuts most of the UV from the spectrum, making the light which passes through kinder to plants. So yes, right in front of your sunniest southerly facing window should be ideal.
