Many regions around the world have moderate sunshine.

What do we mean by moderate sunshine, in a mathematical sense?

We mean that the Direct Normal Irradiance (DNI), a measure of solar radiation, will be in the range 3.5-5.5 kWh/m2/day for these regions. That is, the direct sunlight you get per m2 per day will be in the range 3.5-5.5 kWh.

For these regions, how much electricity generation can you can expect from a 1 kW solar panel?

Assuming you have bought a good quality solar panel and are maintaining it well through periodical cleaning, you can get on average 3.5-4 kWh per day for these regions.

Please note that this average is over a year – which means that on some days (summer for instance), you could get a lot more than 4 kWh per day while on a rainy day, you could be getting a lot less, but taking the total over a year, you will get on average 3.5-4 kWh/day for these moderate sunshine regions.
