> Sorry buddy, the level of ignorance you continue to exhibit about real-life solar is astounding. The fact that you say tuff like this continues to show you are what I call a “google search expert”. Go build something. Learn. Maybe then you’ll understand. Good thing the industry has specific metrics and models for all of these things and there is plenty of data published for integration studies. GTI on a fictional perfect bifacial system on a good day at that latitude in January would be 70-80kWh not 50. A real utility system in easy transmission range of LA including an 85-90% performance ratio is about 50kWh/day in January. You can see clearly from the posted graphs that the system has poor low light performance, less than ideal tilt and that's where the missing energy is. A utility site or well sited standalone off grid system (or one wherebthe building was designed with solar in mind) would not have this. 3.8kWh/day/kWp in January in california isn't some magical ideal. It's completely normal. > You mentioned Singapore. One of our customers has a 300 kW solar array there. Care to guess how much power they actually generate. Hint: Rain. Lots of rain. You completely missed the point here and made it for me. Weather is not latitude. The idea that solar is useless anywhere outside the tropics or that a summer optimised system's winter performance is representative of a winter-optimized system is a myth made up by insane conservatives. Local weather has a larger effect than 50 degrees of latitude during winter. Tilt is also very important -- you do not want to install an off grid system (or a system in a saturated market) at the angle which maximises annual output, you install it at the angle which maximises winter output. Once Europe saturates summer PV, adding more doesn't become useless, you just slap some on a south facing wall or use it as a fence in a paddock. Read. Pay some minimal amount of attention to what you're responding to and to new developments. You also have to learn to listen to people who know more than you think you know.

Your google search isn't a substitute for reality. Lots of words. No link whatsoever to practical, realizable reality. We've had prolonged back-and-forth on this subject a few times. Not interested. I am more than thrilled to talk to anyone who is actually interested in exploring and learning. Just like me. It is obvious that you have no experience whatsoever with solar. If you did you would not continue to post these platitudes. They simply do not make sense to anyone who actually owns and operates a non-trivial solar array. Zero. I understand where you are coming from. You don't know much about this yet think you do because google allows you to post great sounding statement. As the great race car mechanic Smokey Yunick was fond of saying: When all the smoke and bullshit clears out, you have to drive the car and win the race. Smoke and bullshit = Fantasy. Go build a nice solar array. Run if for a few years. Then come back and read some of the stuff you are posting. I know exactly what your reaction will be at that time. Anyhow, as I have said in the past. Good luck buddy. Live long and prosper.

  Care to share which make and model of panels the array is, what the controller is, what angle they're at and what sight lines they have? Or would that prove me right? Being a condescending twit isn't the same thing as knowledge. And being unable to understand that a utility array designed for maximum uptime might behave differently to a home array doesn't make you right. And not understanding that clouds aren't infinitely large doesn't help your case either. Even if you insist that all solar must behave exactly like your array, then simply upping the dispatchable power + pumped hydro to 20% of the total power for the year or adding wind still easily covers a constant load with 12 hours storage and <50% curtailment.
