Cool, but you still get below 5% capacity factor on solar in Poland during the day, and guess what? There's night 16 hours a day.

To calculate the energy produced by a 1 GW solar power plant during a winter month in Germany, we need to consider a few factors: 1. *Solar Insolation*: The average solar energy received per day in winter. 2. *Day Length*: Winter days are shorter, so there's less daylight for solar panels to operate. 3. *Panel Efficiency*: The efficiency of the solar panels in converting sunlight to electricity. 4. *Weather Conditions*: Overcast days are common in winter, which can reduce solar panel output. Let's make some assumptions for a rough estimate: - *Solar Insolation*: In Germany, the winter solar insolation is roughly 1.5 kWh/m²/day. - *Day Length*: We'll assume an average of 8 hours of effective daylight in winter. - *Panel Efficiency*: Modern solar panels are about 15-20% efficient. Let's use 18%. - *Weather Conditions*: We'll assume that overcast conditions reduce effective insolation by 25%. Now, let's calculate: 1. The daily energy output (in kWh) = 1 GW * 8 hours * 18% efficiency * 75% weather factor. 2. Multiply this by the number of days in a month (30 days for simplicity). A 1 GW solar power plant in Germany could produce approximately 32.4 million kWh (or 32.4 GWh) of energy during a typical 30-day winter month, considering the factors and assumptions outlined earlier. Hit me up in 2040 when Poland’s first nuclear power plant finally opens a decade behind schedule snd costing the usual ~10x of the estimate.

  You do so much assumptions yet they don't match reality _at all_. >A 1 GW solar power plant in Germany could produce approximately 32.4 million kWh (or 32.4 GWh) of energy during a typical 30-day winter month, considering the factors and assumptions outlined earlier. Okay, so this means on average 1GW of solar power should output ~1GWh of energy daily, right? So Germany's roughly 80GW of power would produce on average 80GWh of electricity? Well, let's look at _real_ data: https://app.electricitymaps.com/zone/DE https://app.electricitymaps.com/zone/DE In the last 30 days there was exactly one day with over 80GWh of solar power produced: 9th January. And it was just 81GWh. Yet there was multiple days where actual electricity produced barely went over 10GWh... or not even 10GWh, like 21 December with 7GWh produced. Three days ago, it was 14,5GWh. Overall solar power production in Germany in December was 795GWh, below 1/3 of your estimate.
