Every dot is a solar installation someone submitted. Its colour = how big the whole system is (total capacity, every panel added together, in kWp). The red mark is the one you just saved — click it to see everything you entered. This turns lots of small, separate installations into a picture of the country's solar.
kWp = kilowatts peak: the capacity of the whole system, with every panel added together. Example: 8 panels of 400 W each = 3.2 kWp for the whole system, while one panel on its own is only 0.4 kWp.
