Good one. Maybe the best comment of the week.
Sounds like an installer problem – with a good legal claim
Good luck with that mate. You’re dealing with a French company.
Looks like a lot of pollution. Luckily it wasn’t a hail storm.
the solar panels also don’t work well when they’re covered in snow. they don’t do much at all when it’s dark out, like in the winter when it’s dark 2/3 of the day. probably a super cloudy day isn’t a big money maker either. Add that all up and you would think that those are good reasons not to have solar farms, but apparently the greenies think those are reasons to have more of them.
And they are a ridiculous notion for anywhere in Great Britain because according to MODIS data there is an average 21.3% chance of a cloud free day over the whole region.
And London has 35 clear days, 180 partly cloudy days, and 150 overcast days per year.
My small solar/battery back up system for our Florida Hurricane season has 400 watts nameplate solar panels (monocrystaline, the highest efficiency), and on the best cloud free time, they only put out about 320 watts. And even a teensy white cumulus cloud will drop the output to 130 watts. Overcast will drop it to 70 watts. So in overcast the panels are only 17.5% of nameplate, and partly cloudy are then 32.5% of nameplate and even full sun are only 80% of nameplate.
And solar is only good for 6 hours a day or 25% of a day.
Combining these empirical values yields:
Sunny in GB = 80% nameplate capacity x 25% = 20% of daily output
Partly cloudy in GB = 32.5% x 25% = 8.13% of daily output
Overcast in GB = 17.5% x 25% = 4.38% daily output
What the heck is wrong with people who design and install these systems? You cannot expect a reasonable return on investment with these low efficiency values, especially with a 15 year lifetime of solar panels, and worse if they are storm damaged.
So my 400 watt nameplate example, set in GB yields a nameplate annual value of 876 kW-hours. And with actual sunny, cloudy and overcast taken into account they would only generate 288.6 kW-hours of energy annually.
So the system cost about $2,100 for panels, structure, batteries, inverter, charge controller and wiring. If you got $0.10 per kW-hour wholesale that would be $28.86 per year income, so it would take 72.8 years to recover the initial cost. Of course economy of scale would apply to a big solar farm, so maybe it would take 25 years to recover the initial cost at scale, but they only last 15 maybe 18 years at best….
Solar is just not feasible for replacing a full time power grid. Special cases where you cannot access the grid, and cannot easily get fuel to an engine/genertor yes solar is a good idea, otherwise it simply does not measure up or add up.
(I built mine because our condo association does not allow generators, so this way when mains power is out after a storm, we can run the fridge, microwave, some fans and lights)
Damn you for pointing out the cloud cover “challenge”. Now, watermelons will INSIST on MOBILE solar plantations–so they can chase the sun;-}
The watermelons overlook the fact that the energy required to chase the sun will nullify the energy generated by the plantations, a kind of Net Zero. And it may be cloudy during the duration of the chase. Not to mention that plantations are racis’. But in the Green Utopia of the future that chasing energy will be generated by Majick
Good sarcasm! Reminds me of some legendary lyrics:
And you run, and you run
To catch up with the sun, but it’s sinking
And racing around
To come up behind you again
The sun is the same in a relative way
But you’re older
Shorter of breath
And one day closer to death
(Pink Floyd – “Time”)
The left is infatuated with land consuming technologies.
The solar farm’s owners need to be charged with littering…
Yeah, what happened to life cycle costs, e.g. the disposal costs for old solar collectors, or damaged ones? We will have an equal sized area for solar collector waste disposal?
These days many modern solar panels operate on daylight and do not need sunlight. So many more panels will still work well in conditions of cloud cover..
Nice polishing of the solar turd Patrick. So are you claiming these “daylight” solar panels are 100% efficient on cloudy days?
Asking for a friend 😉
My panels which are only a year old drop to around 5-10% efficiency in cloud cover. Hardly enough energy to lift the lid on a rice pudding.
Once upon a time storms were storms. Now they are Killer Storms with names. The increase in the number of “named storms” is then presented as evidence that Global Boiling is real. Questionable logic. By extension if solar farms had been built decades ago instead of burning fossils for energy “Darragh” never would have happened. The blood of these expensive but inefficient solar panels is on the hands of Climate Deniers.
The same thing has happened in other countries – with both solar “farms” and wind turbines – both solar and wind power are vulnerable to storms.
In short, green energy ain’t so friggin’ green…. if even at all.
