I think the idea is that it’s the same amount of light is being used but the actual expensive part of the solar cell is cheaper and designed to take the increased heat. So the same size “solar unit” on the roof collecting the same amount of light and generating the same amount of energy but cheaper overall. At least that was my take. Correct me if I’m wrong.

What was the stuff like this of 15 years ago ?

Solar energy experts in Germany are putting sun-catching cells under the magnifying glass with astounding results, according to multiple reports.

The Fraunhofer Institute for Solar Energy Systems team is perfecting the use of lenses to concentrate sunlight onto solar panels, reducing size and costs while increasing performance, Interesting Engineering and PV Magazine reported.

The "technology has the potential to contribute to the energy transition, facilitating the shift toward more sustainable and renewable energy sources by combining minimal carbon footprint and energy demand with low levelized cost of electricity," the researchers wrote in a study published by the IEEE Journal of Photovoltaics.

The sun-catcher is called a micro-concentrating photovoltaic, or CPV, cell. The lens makes it different from standard solar panels that convert sunlight to energy with average efficiency rates around 20%, per MarketWatch. Fraunhofer's improved CPV cell has an astounding 36% rate in ideal conditions and is made with lower-cost parts. It cuts semiconductor materials "by a factor of 1,300 and reduces module areas by 30% compared to current state-of-the-art CPV systems," per IE.

OK, take that Fresnel lens that you were using to melt pennies and then focus it on a PV cell that is also made of metal. What might be the expected response? The science in this case is making PV cells that can handle the intense heat.

Honestly solar panels and electric cars. I know those existed over 15 years ago, but they weren't serious market options until like 5 or so years ago.

If I had a penny for every time I heard about new advancements about to revolutionise solar panel technology, I'd have glazed the bloody Sahara with them by now.

First known electric car was built in 1837. Yes, 1837, not 1937. In 1910's and 1920's there were tens of thousands electric cars in USA and Europe. So electric cars has been here for a long time right now.

First (known) solar panel was built in 1954.

"Has the potential to contribute...." Wow. Amazing.

Solar panels are already quite cheap. What we need is much cheaper grid forming inverters so we can stop destabilizing the grid with solar.

Wait for something fucking idiotic like:

"U.S. government to implement 5,000% tax on new solar technology...."

I suspect that the lens makes the whole solar assembly more directional and the Sun moves in the sky.

Would the cost chart of PV cells look something like this?
