Interesting point that because solar panels are connected in series, if e.g a leaf falls on the panel, it will prevent the entire series from generating power (and sometimes even burn the cells).

Cones are for color, rods are for night and peripheral vision.
Human eye can take in ranges of light across 12 orders of magnitide (better than any sensor we've built). But we can only take 3 orders of magnitude in at the same time. In a bright environment, your body sprays water into your cones to dilute them.
There are 4 quantities to know. 2 numbers to describe light sources, and 2 numbers to describe a space. Luminous flux: how bright a light is, luminous flux: the spectral intensity of a light, illuminance and luminance: the amount of light you get.
Luminous intensity is measured by candellas. The power emitted by a light source in a particular direction.
Luminous flux (power) if most often used when dealing with a lighting system. Measured by lumens.
Depending on the tech used, we can create more or less visible light with the same input. The most energy efficient is monochromatic green light.
Luminance. What most people find confusing. A quantity used to describe how someone views a space. We can measure it with an expensive device or with high dynamic range photography.
Being able to measure and evaluate these quantities through new tech has enabled a lot more discussion and analysis around them. They are much more accessible than in the past.
As a rule of thumb, keep a 3:1 ratio of luminance between the near and far field in the field of view. This kind of thing is really easier to check with the software.
Illuminance is easier to understand. The overall amount of visible light that falls on a sensor.
People don't often change their dimming system after they set it once, but that doesn't mean its a waste to provide the capability. Compare with e.g. an office chair.
Another very straightforward assignment for Track 1. Basically just plug numbers into some simple formulas. I do wish I was on top of the track 2 assignments but there's just not quite enough resources for me to make the jump.
