I selected random date in July 2025. During that time Finland produced about 10GWh of solar. I selected random one from February 2025. During that Finland produced about 0.5GWh. February also actually doesn't have shortest daylight hours, mid-December situation is even worse. Christmas Eve 2024 produced about 0.05GWh.
You sure overprovision factor of 200x is still cheaper? This is when looking at the peak generation. From what I understand solar has about 30-40% capacity factor in summer. Just to panels (I'm not sure about total cost of grid-scale solar) seem to be about $300k per rated 1MW or $750k per 1MW during peak. $150M per 1MW during December. OL3 cost about 11B € for 1.44GW (assuming 90% capacity factor) or 7M € per MW.
Unless there has been some huge overnight exchange rate change 7M € seems much cheaper than $150M. Latter of course would actually be much higher when you factor in rest of the equipment, labor etc. Some numbers I found say that it's probably 5x higher.
