If we had a 300 Watt solar panel in direct sun,that relies on photons to hit the solar cells in it, when the most photons are hitting it, it can send 300 Watts to a battery in an HOUR. Not in a moment. The time during a day when the most photons are likely to be on the panel is between 10:00 AM and maybe 3:00 or 4:00 PM in the summer. Lower light levels in the winter would narrow those hours down. Shade narrows those hours down.
So if a computer screen or a TV screen uses 300 Watts an hour, yet we have them turned on for many hours, that's where the solar cannot keep up with our draining the system by using appliances. Most kitchen appliances use 1000-1500 Watts an hour, coffee pots, microwaves, blenders, a one-burner electric cooktop, an electric water heater -- anything that makes heat or has a small motor. We may not have them on that long, but together they add up and drain the system faster, especially in the winter.
Luckily we have LED lights, and those make it possible to have lights that don't drain the system so much.
I have enough panels to give me 1,000 Watts in an hour. It's not a big system. However, if it's foggy or cloudy they can generate 25 Watts an hour, all of them put together. Doesn't matter if it's noon, if the photons from the sun are being blocked by clouds or fog.
So that ought to help us appreciate how efficient the human eye is, and how it can use the photons in miraculous ways, much better than a solar panel can.
