Posted By: TrimArxiv PdfThat headline quote is so fundamentally wrong that it isn't worth looking further.
Today, Marco Bernardi and pals at the Massachusetts Institute of Technology in Cambridge say there is a simple fix that could dramatically increase the performance of photovoltaics. Instead of two dimensional flat panels, Bernadi and co suggest using three dimensional structures.
They've simulated the performance of various shapes and tested several of these on the roof of a building at MIT. Their results indicate that 3D structures can increase the amount of energy that can be generated by a given footprint by as much as 20 times. These structures can also double the number of useful peak hours of generation and reduce seasonal variation to boot.
How 3-D Photovoltaics Could Revolutionize Solar Power
Posted By: ping1400Just bought a 3.1 kW solar system (20 m2 panels, inverter, cables, construction rails and bolts) for 3600 Euro including tax. With a residential electricity price of 23 cents/kWh my solar system will pay back in 5 years. The panels are guaranteed for 25 years.
Edit: price of solar systems is dropping at redicule tempo, same system did cost 6500 Euro 1.5 year ago. We are reaching almost 1 euro per watt peak system costs. It is expected the system prices will drop another 50% next 5 years.
