   « Another weekend, another weekend of negative wholesale #power prices this time across most of #Europe. Basically from 11.00-17.00 today most countries from #France to #Finland will have power prices of zero or below. » #RePowerEU

     ☀️⚡️ Everyone in Switzerland agrees we need more solar. But often, there's disagreement about where to put the panels without impacting the landscapes too much.

     🛤️ Looking back, this one is a no-brainer, why not lay them down between train rails: there's already a strong connection to the grid, and it's infrastructure that's already ‘built’.

     🇨🇭 First segment of the tracks got inaugurated today in canton Neuchâtel.

     « It’s an increasingly common phenomenon as Europe races to build more cheap solar farms to cut demand for fossil fuels. Intraday prices in Germany, the region’s biggest power market, turned negative from 1 p.m. to 3 p.m. on Tuesday, according to data from Epex Spot SE. » https://www.bloomberg.com/news/articles/2023-07-04/power-prices-drop-below-zero-as-solar-output-surges-in-europe

     @fj do the panels stay clean enough? isn't it quite dirty with dust, abrasions and since it's lying down flat? :l_curious:

     @kaia @fj Brushie brushie train carriages
     (realistically, if it's laid like that it requires people on cleaning duty, and good luck if there's heavy rains or snow)
