The napkin math factor I use is to get the average power you need to divide solar and wind's name plate power by about 4. So to get the same amount of total yearly energy as a 1GW nuke plant that runs 24/7 you need 4GW of solar. Because solar produces about 6 hours of power per 24 hour day.
From a capital cost perspective this is not nice at all. Too be fair upside of solar/wind is solar and wind farms don't go down for a year and a half of unplanned maintenance like nuke plants sometimes do.
- angiosperm 3y agoWind is rather better than 25%, most places where it is used.
- Retric 3y agoGrid PV in a good location is more like 30% capacity factor. They typically use 1 axis tracking to collect more power in morning and evening due to the demand curve. Ex: 32.8% https://en.wikipedia.org/wiki/Solar_Star https://en.wikipedia.org/wiki/Solar_Star
