Hallo Leute. In letzter Zeit war ich neugierig, wie sich Solarenergie und Batterien als stabile Energiequelle in Kalifornien entwickeln, da sie in diesem Bereich in den gesamten USA dominieren. Hier ist die Originalartikel Ich habe geschrieben, wenn Sie neugierig sind. Leider sieht es so aus, als würde es nach Sonnenuntergang nur etwa 4 Stunden lang Strom liefern. Betont wirklich den Punkt, dass wir mehr in diese Technologie investieren MÜSSEN, wenn wir damit fossile Brennstoffe ersetzen wollen.

This visualization was generated by pulling from the California ISO database, using the python API. The visualization was made using matplotlib. Check out the GitHub repo for this visualization here, which includes all code and data used to generate it:

Only provides power for 4 hours after sunset (and the whole rest of the daylight hours).
That’s 1.5 years ago. Can you do this with more recent data? I expect it has changed quite a bit?!
I’m no electricity scientist but I’d suggest that electricity use is pretty low from 12am to 6am while 95% of people are…. sleeping. Also, include wind and hydro in your analysis as well as intergrid connections and you’d have a better understanding of the feasibility.
I like that the curves look like lightbulbs though, haha
For those who weren’t aware, even Coal plants use batteries to store electricity during downtimes. Not that this is 100% relevant to the discussion here, but as it was a huge argument with my father recently, I just wanted to share some research I had to do.
That’s best case scenario in July, what about late December?
A fleet is a collection of vehicles, usually seafaring. I don’t think that’s what you meant.
Have you considered that this pattern matches demand, and that the battery usage suggests a deliberate wind down of production as households go to sleep?
„Investing“ as in Solyndra? There are issues with solar that aren’t being addressed up front – damage to units by the weather, difficulty in clearing them under heavy snowfall, normal deterioration of the cells in ten years, replacement costs of substrate when mounted on roofs (charge to remove, charge to install, revocation of roof warranty with the very first fastener) recycling materials ( gonna bury them with wind turbine blades? They recently found an illegal dump.)
While the socalled fossil fuels are required to report every single expense from „birth“ to disposal“.
This is good info since it shows how the Texas Winter and no grid connection was a disaster, and applying it to RV use means many report things not working well other than desert areas. In winter prone locations with high power consumption and weeks of cloudy weather plus reduced winter sunlight its promoting the use of diesel heaters and even wood stove installations.
Lets also remember than our source for most of these panels were underwritten by their .Gov to create an unfair market advantage. Now that they have to compete with other sources and there is no taxpayer incentives we are seeing how the real market influences sales.
I still see a better return on proper windows and insulating a home, any legit survey of a potential solar installation usually involves upgrades to lower energy consumption modern appliances and much better weatherproofing – reduce your demand first to meet the reduced supply. That works regardless of the utility you use to power the house, yet its often ignored in the influencer focus on solar.
I think you are misinterpreting your own graph. The batteries are never going empty; they only stop providing power after 4 hours because demand is less than supply.
A few more batteries should sort it out.
The answer to the headline is: incredibly stable
That little sliver between solar and combined is our battery storage capacity (MWh)… that’s all that we’re bringing over to the evening. We need enough battery storage to have some energy left in the batteries when the sun comes up, if we want to even consider replacing natural gas.
„hey guys, I don’t know shit about energy demand and battery usage, but here’s a graph“
conclusion: „solar bad, oil good“
