Island power
The generators are carrying the island and charging the batteries.
There is no power line to the mainland. Everything the island runs on is made here — by the solar array, the battery bank it charges, and the generators that cover the rest.

Each bar is how much power is moving, and the arrow says which way. When the batteries are full or the sun sets, they stop filling up and start feeding the island instead.
Battery bank
18%
Charging. The bank stores daytime sunshine so the island can run on it after dark instead of burning diesel.
Powered by the sun right now
0%
Nothing from the array after dark — but a large share of tonight's power was made by the sun today.
Made by the sun today
0 kWh
That is energy, not power — the total collected since midnight. The array has made 418k kWh in the last thirty days.
Today so far
Every reading from the island since midnight. Where the gold rises above the blue, the sun is making more than the island can use and the extra is going into the batteries.

What the numbers mean
kW — kilowatts
How much power something is making or using at this instant. One kilowatt is roughly one hair dryer running. The whole island sits somewhere between 450 and 1,000 of them.
kWh— kilowatt‑hours
Power added up over time — the same word your electricity bill uses at home. One kilowatt running for one hour is one kilowatt‑hour.
Why the generators still run
They cover the gap before sunrise, after a long grey day, and whenever the batteries run low. Every kilowatt the sun and the batteries supply is a kilowatt of diesel not burned.
Readings come from the island’s own power system and refresh every few minutes. The full engineering view lives at solar.chubcay.com.
