Do solar panels work at night?

Which panel should face the sun?

The post is fixed, 16 meters of range, and the cheapest kilowatt if you only care about noon. It stores nothing, so a press that runs into dusk will stall. The twin is also fixed, so you aim it when you place it, and its 4 kWh is the small night buffer. Range on that row is 24 meters. The tracker spends $300 to rotate, holds 10 kWh, and reaches 34 meters. I would buy a twin before a tracker if the load is one 10 kW chamber, because a post plus a twin is the $225 pair the solar page already names. A lone tracker at 16 kW still does not cover an 18 kW Stone Press.

Foundations and whether a pad shades a panel are a thin topic. One search asks if foundation affects output. The solar page does not give a penalty number, so I will not invent a percent. Place panels where the sun graphic is obvious and do not stack them under a roof you cannot prove is harmless.

The array that adds no kilowatts

Solar Array is a different row, $250, listed at 0 kW on the machine table. One source says it does not enter the power sum. I am not recommending it as a generator. Battery Bank exists as its own row in the machine list and is not given a kilowatt-hour figure in the short fields I copied, so its capacity stays on the table rather than in this sentence. Night length itself is not settled: a 60 minute cycle with 30 minutes of sun is one summary, and a 20 minute loop of 13 minutes day, 1 minute sunset, and 6 minutes night is another. The third comment is that the studio never published a single clock. I refuse to average those into 40 minutes.
