They're getting 180 watts per meter, so it would take 50 km of panels to power one high speed train. And that's when the sun is shining. Double this at least if you want to store the energy and run trains in the evening.
replyThis is incorrect, you mean 180 kWp/m.
reply> in one year, the project has produced around 16,000 kWh.
160 kWh per meter.
Urban Metro / Trams: 2 to 10 kWh/km
Commuter Trains (EMUs): 4 to 12 kWh/km
Regional / Intercity Trains: 6 to 20 kWh/km
High-Speed Trains: 15 to 60 kWh/km
Freight Locomotives: 10 to 50+ kWh/kmIt's obviously not 180 kWp/m. If it was I could put 1 meter of panels on my roof and power my house and 200 of my neighbors.
replyI didn't try to calculate the amount of energy it produces in a year, just the length of panels required to power a high speed train when the sun is shining. 18,000 watts / 100 meters is 180 watts per meter. At 180 watts per meter, 50 km gives you 9 MW, which is about what a high speed train consumes at cruise.
> This is incorrect, you mean 180 kWp/m.
replyThis is incorrect. 18000 Wp/100m = 180 Wp/m or 180 kWp/km. So parent is correct, and you can either add or drop a "k".
That is peak power, obtainable in summer months & muuch less in winter.
Over the whole year: 16000 kWh/100m = 160 kWh/m = 160 MWh (160,000 kWh) per km.
