  • Solar panels don’t generate constant power! That’s why it’s wrong because you’ll get wrong numbers. You can’t assume you’ll get peak output continously.

    You *** must *** calculate incoming and absorbed light. The Watt output will vary continously as the sun moves and weather changes. If you have average kWh / day stats and a battery solution that can store a day of battery, THEN you can calculate average Watts if weather doesn’t change too much.








  • Technically yes but also no.

    Synchronized reading is hard when the pixel count is high. At some point it’s hard enough to pull all the data through the controller at once quickly so you need either multiple circuits, or one circuit that reads a section of pixels at once (row by row = rolling shutter effect).

    Some of this is processing limits in the internal controller in the sensor, but it’s also timing and signal routing and synchronized readout for a massive amount of pixel sensors. It’s literally tens of millions of triplets of RGB detectors which has to be read simultaneously 60 times per second, and basic color correction has to happen right in the controller, before the main CPU / GPU gets the image stream.

    At some point you even get cooling issues, and need a cooling system behind the sensor.

    In Sweden it’s default to have 3 phase available, and different groups of rooms are often on a different phase in bigger apartments or homes.

    Connecting two different phases directly puts 400 V on a “short-circuited” wire instead of 230V with no current…
