Lessons Learned

Compared to Planta Solar 10, Planta Solar 20 made many modifications, it has much longer steam accumulators, bigger pipe and equipment sizes, and bigger displacements relative to the thermal expansion. The engineering design was created by MicroStation and OpenPlant. Currently, the PS20 solar field could generate 48GWh/year, and will be able to supply about 12000 households.
