Eventually day time solar power production could be more than 100% of what is being used at that time. In that case the power grid would need to be changed to allow storage for later use.

Storage is cheaper if it is used more frequently. More income is produced.

Moving late night electricity to the morning peak and solar into the late day peak means that storage would get used twice a day.

One such place is the “The Energy Collective”. However it happens everywhere. Is there a centralized list of these propaganda sources?

Euro 1500-1700.

Despite the fact that the Germany is already above 5% solar electricity, and despite the fact that electricity is cheaper at night, coal power plants are still producing more power during day time than at night.

Introducing day time storage would be very unwise, since it would only increase coal power demand!

All the stuff aside from the panels. Racks, inverter, wire, conduit, labor, permits, etc.

Just a few years back panel prices greatly exceeded the BOS stuff, now it’s the other way around.

Here I was under the impression that energy in Germany was being sold at peak hours to neighboring countries at outrageous prices. Making Germany rich rich and richer. And anything that can’t be used or sold is being taken up by the power-to-gas projects to supply the transportation industry. Germany is just laughing all the way to the bank while we try to justify what they do as “possible”.

We have seen articles here in Cleantechnica on how Germany is attempting to compete against China by automating the entire fabrication of PVs. Apparently Germany feels they can recapture the market and produce the PVs with machines cheaper than China can with slave labor. How then can the author Christian Roselund claim China is dumping when Germany thinks they can still out compete them fairly?

Or that prices aren’t coming down?

Or that other countries won’t be able to install as cheaply as Germany can?

Oh, and what areas might they work in? Not nuclear research by chance?

Apparently being able to fill the roof with panels is one way to bring down the price per watt cost. It certainly spreads the cost of sale, setup and delivery costs over more watts. Getting labor and equipment to the site costs. A full roof array requires no more labor to run cable and hook to the grid than a smaller array.

I think we need a model where companies lease entire rooftops from home/business owners, fill the sunny slopes with panels, and sell power to the utility. I suspect done right they could be competitive with utility sized solar. Line up a bunch of roofs in a small area and send in specialized crews to do the various parts of the job.

That means that overall company profits will be made based on volume and volume will be determined by price which is largely determined by manufacturer efficiency.

And that means that the weaker/less efficient manufacturers are being pushed out.

It’s something that happens with almost any emerging technology as they mature. It happened with computers and with cell phones. There were a lot of players along the way but only the strong survived. And we got cheap technology out of the process.
