Fancy goldfish growth

Actually it doesn't get any direct light in the summer. The sun rides too high. In the winter the sun is lower and will shine in on the tank a little. The tank does get a lot of natural light just not direct

Natural light will affect algae growth too but just doesn't make algae grow as fast. If the amount of natural/direct light peaks at 3 pm, make the timer turn the light on at around 9-10 am and turn off around 5-6 pm.
